The fixed portion 301 of the button seat 30 may be provided with a protruded portion 3011. The protruded portion 3011 may extend outward from an outer side of the extended portion 302 along a radial direction of the extended portion 302 and may extend by a predetermined width along a circumferential direction of the extended portion 302. The protruded portion 3011 may be provided with an installation hole 3011-a through which the button seat 30 and the main body 1 can be fixedly connected by a connector. The button shaft 31 may include a fixed end 311 and an extended segment 312 extending from the fixed end 311 in a direction towards the main body 1. The fixed end 311 and the pull handle 2 may be fixedly connected, and the extended segment 312 may extend into the cavity of the button seat 30. The extended segment 312 may include a cross-section along the axial direction, and the cross-section may be recessed in a radial direction of the extended segment 312, and the chute structure 310 may be disposed on the cross-section, i.e. the cross-section may provide an arrangement space for the chute structure 310, and the cross-section may be provided as a horizontal cross-section. An inclined notch 3110 may be provided at the fixed end 311, the fixed end 311 may be installed in the housing hole 2010, and the inclined notch 3110 may be clamped with the positioning post 201 to prevent the fixed end 311 from falling off. The elastic element 33 may be provided in the cavity of the button seat 30, and may include a connecting end 330 fixed to the fixed portion 301 and a positioning end 331 extending from the connecting end 330 in a direction towards the pull handle 2.

In this embodiment, the elastic element 33 may be provided as a spring, and the extended segment 312 and the slide positioning element 32 may be sleeved in the spring. The slide positioning element 32 in the embodiment of the present application may be provided as a hook and slide hooks 320 (as shown in FIG. 10) may be respectively provided at both ends of the slide positioning element. The button seat 30 may include a circlip 3012 provided at the fixed portion 301. After the fixed portion 301 is installed to the main body 1, the fixed portion 301 may be limited by the circlip 3012 to prevent the fixed portion 301 from falling off.

[0015] As shown in FIG. 7 and FIG. 8, the chute structure 310 may be of a vane type as a whole and may include a first travel groove 3101 and a second travel groove 3102 that form a cyclic path. The first travel groove 3101 may include a first arc groove 3103 and a first bend groove 3104. The second travel groove 3102 may include a second bend groove 3105 and a second arc groove 3106. The first bend groove 3104 and the second bend groove 3105 may intersect to present a V-shape, and a first lock position 3107 may be provided at their intersection. The first arc groove 3103 and the second arc groove 3106 may intersect to present a V-shape, and a second lock position 3108 may be provided at their intersection, and the first lock position 3107 and the second lock position 3108 may be spaced apart with a predetermined distance along a full length direction of the extended segment 312. The slide positioning element 32 can slide in the chute structure 310 and can be clamped at the first lock position 3107 or the second lock position 3108, so as to drive the pull handle 2 to switch between the first state and the second state. When the slide positioning element 32 is clamped in the first lock position 3107, the pull handle 2 may be in the first state, and when the slide positioning element 32 is clamped in the second lock position 3108, the pull handle 2 may be in the second state.

[0016] Transition steps may be disposed at joints between the first arc groove 3103, the first bend groove 3104, the second bend groove 3105, and the second arc groove 3106, and heights of the transition steps may be reduced along a direction of a sliding cyclic movement of the slide positioning element 32 within the chute structure 310. As shown in FIG. 8, the slide positioning element 32 may move in a counter-clockwise cyclic direction within the chute structure 310, and a transition step may be provided at a joint between the first arc groove 3103 and the first bend groove 3104, so that a height of the first arc groove 3103 is greater than that of the first bend groove 3104 at the joint. A transition step may be provided at a joint between the first bend groove 3104 and the second bend groove 3105, so that a height of the first bend groove 3104 is greater than that of the second bend groove 3105 at the joint. A transition step may be provided at a joint between the second bend groove 3105 and the second arc groove 3106, so that a height of the second bend groove 3015 is greater than that of the second arc groove 3106 at the joint. A transition step may be provided at a joint between the second arc groove 3106 and the first arc groove 3103, so that a height of the second arc groove 3103 is greater than that of the first arc groove 3105 at the joint.

[0017] According to the embodiment of the present application, transition steps with reduced heights are provided at the joints between the first arc groove 3103, the first bend groove 3104, the second bend groove 3105 and the second arc groove 3106, so that the slide positioning element 32 can be guided to change its state in an orderly manner during cyclic movement, and reverse sliding, sticking, positioning failure and the like can be prevented.

[0018] As shown in FIG. 9-FIG. 13, when the sliding switch device 3 is installed to the main body 1 and the pull handle 2, the fixed portion 301 of the button seat 30 may be installed in an installation groove 101 of the main body 1, and the protruded portion 3011 may be connected and fixed to the bottom wall of the main body 1 through a connector. An outer wall of the fixed portion 301 may be provided with a recess 3010, and the installation groove 101 may be provided with a buckle portion 1010, and the recess 3010 and the buckle portion 1010 may be clamped with each other. The fixed end 311 of the button shaft 31 may be installed in the housing hole 2010. The extended segment 312 may extend into the button seat 30 and may be sleeved within the elastic element 33. A slide hook 320 at one end of the slide positioning element 32 may be fixed to the fixed portion 301, and a slide hook 320 at the other end of the slide positioning element 32 can extend into the chute structure 310 and slide in the chute structure 310.

[0019] During operation of the door handle of the embodiment of the present application, assuming that the door handle is in an initial state in which the door handle is in a position released from the housing groove 10, the slide positioning element 32 is clamped at the second locking position 3108 (as shown in FIG. 13), and the pull handle 2 is in the second state. When the pull handle 2 is pressed, the elastic element 33 is compressed, the button shaft 31 is forced to move in a direction towards the main body 1, a slide hook 320 of the slide positioning element 32 undergoes a pressing force from the button shaft 31 to move along a counterclockwise direction within the chute structure 310, to slide from the first arc groove 3103 towards the first bend groove 3104, and after the slide hook 320 reaches the first bend groove 3104, the pull handle 2 is no longer pressed, the elastic element 33 is partially released, which drives the slide hook 320 to retract and be clamped at the first lock position 3107 (as shown in FIG. 12), and a distance between the pull handle 2 and the main body 1 is reduced. In this case, the pull handle 2 can be received in the housing groove 10 of the main body 1 and is in the first state. The pull handle 2 is pressed again, the button shaft 31 is forced to move in the direction towards the main body 1, the slide positioning element 32 is disengaged from the first lock position 3107, moves along the second bend groove 3105 towards the second arc groove 3106, and after the slide hook 320 reaches the second arc groove 3106, the pull handle 2 is no longer pressed, the elastic element 33 is released and pushes the button shaft 31 to move outward. Under the driving of the elastic element 33, the slide positioning element 32 can slide along the second arc groove 3106 towards the second lock position 3018 and clamped at the second lock position 3018, so that the distance between the pull handle 2 and the main body 1 is increased, and the pull handle 2 is released from the housing groove 10 of the main body 1. In this case, the pull handle 2 is in the second state again.

[0020] The sliding switch device 3 of the embodiment of the present application has advantages of simple structure, convenient installation and operation, good pressing effect and being uneasy to get stuck.
