    [0036] After the rotary shift set 20, the height adjusting assembly 30, and the tightness adjusting set 40 are coupled together, the abutting post 32 is clamped by the two retaining portions 31 of the first retainer 11 and the second retainer 12, and the two hollow engaging portions 13 of the first retainer 11 and the second retainer 12 are engaged with the handlebar 60, then the positioning bolt 14 is screwed with the first retainer 11 and the second retainer 12 so as to lock the handlebar 60 and the abutting post 32, hence the rotary shift set 20, the height adjusting assembly 30, and the tightness adjusting set 40 are mounted on the handlebar 60, and the rotary shift set 20 and the abutting post 32 are fixed by the two retaining portions 31 of the first retainer 11 and the second retainer 12.

    [0037] Referring to FIGS. 3-5, as desiring to adjust a position or a height of any one of the clamping assembly 10, the rotary shift set 20, the height adjusting assembly 30, and the tightness adjusting set 40, the positioning bolt 14 is unscrewed but not moved away from the first retainer 11 and the second retainer 12 so that the two hollow engaging portions 13 of the first retainer 11 and the second retainer 12 disengage from the handlebar 60, the abutting post 32 is unclamped by the two retaining portions 31 of the first retainer 11 and the second retainer 12, hence the handlebar 60 and the abutting post 32 are moved relative to the two hollow engaging portions 13 and the two retaining portions 31 so that the clamping assembly 10, the rotary shift set 20, the height adjusting assembly 30, and the tightness adjusting set 40 are moved linearly along a central axis direction of the handlebar 60, and the rotary shift set 20 and the height adjusting assembly 30 move along a central axis direction of the abutting post 32, such that the rotary shift set 20 and the height adjusting assembly 30 slants at a predetermined angle θ relative to the handlebar 60.

    [0038] After the positioning bolt 14 is screwed, the first retainer 11 and the second retainer 12 are engaged together so as to retain the handlebar 60 and the abutting post 32, hence the two hollow engaging portions 13 of the first retainer 11 and the second retainer 12 engage with the handlebar 60, and the abutting post 32 is clamped by the two retaining portions 31 of the first retainer 11 and the second retainer 12.

    [0039] With reference to FIGS. 6 and 7, as desiring to drive the bicycle device 50, the rotation member 22 is shifted so that the second end of the steel rope 44 is pulled to become curved, and a part of the steel rope 44 inserted into the abutting post 32, the screwing element 41 and the fitting member 43 is pulled to move toward the rotation member 22, thus driving the bicycle device 50.

    [0040] After releasing a shift of the rotation member 22, the part of the steel rope 44 inserted into the abutting post 32, the screwing element 41, and the fitting member 43 is pulled to move away from the rotation member 22 so that the second end of the steel rope 44 is pulled to return back to an original position.

    [0041] As shown in FIG. 8, after rotating the rotatable button 42 to adjust a position of the screwing element 41 relative to the abutting post 32, the longer the length of the screwing element 41 exposes outside the abutting post 32, the longer a length of the steel rope 44 exposes outside the fitting member 43, so the steel rope 44 is pulled tightly to rotate the rotation member 22, thus driving the bicycle device 50 finely. On the contrary, the shorter the length of the screwing element 41 exposes outside the abutting post 32, the shorter the length of the steel rope 44 exposes outside the fitting member 43, so the steel rope 44 is pulled loosely to rotate the rotation member 22, thus driving the bicycle device 50 insensitively.

    [0042] The height adjusting assembly 30 is provided to adjust the height of the rotary shift set 20 based on using requirement.

    [0043] The height adjusting assembly 30 is one piece formed on the clamping assembly 10 and the rotary shift set 20, thus simplifying structure and lowering weight.

    [0044] By unscrewing the positioning bolt 14, the position of any one of the clamping assembly 10, the rotary shift set 20, the height adjusting assembly 30, and the tightness adjusting set 40 are adjusted relative to the handlebar 60, and the height of any one of the clamping assembly 10, the rotary shift set 20, the height adjusting assembly 30, and the tightness adjusting set 40 relative to the handlebar 60 are adjusted according to using requirement, thus adjusting positions and heights of the clamping assembly 10, the rotary shift set 20, the height adjusting assembly 30, and the tightness adjusting set 40 relative to the handlebar 60 easily.

    [0045] The rotating the rotatable button 42 is rotated to adjust the position of the screwing element 41 relative to the abutting post 32, wherein the longer the length of the screwing element 41 exposes outside the abutting post 32, the longer the length of the steel rope 44 exposes outside the fitting member 43, so the steel rope 44 is pulled tightly to rotate the rotation member 22, thus driving the bicycle device 50 finely. On the contrary, the shorter the length of the screwing element 41 exposes outside the abutting post 32, the shorter the length of the steel rope 44 exposes outside the fitting member 43, so the steel rope 44 is pulled loosely to rotate the rotation member 22, thus driving the bicycle device 50 insensitively. In other words, the user can adjust the tightness of the steel rope 44 on basis of using requirement.

    [0046] FIG. 8 is a cross sectional view showing the application of the shifting structure for the bicycle according to the first embodiment of the present invention, wherein the bicycle device 50 is a front fork damper, a braking device, or a seat adjustment device, and wherein the first end of the steel rope 44 is connected with the bicycle device 50 so as to control an operation of the front fork damper, the braking device, or the seat adjustment device. Likewise, the shifting structure can be also fixed on any one of a top tube, a down tube, a seat stay, a chain stay, and a front fork tube of a bicycle frame.

    [0047] With reference to FIGS. 10 and 11, a difference of a shifting structure for a bicycle of a second embodiment from that of the first embodiment comprises: two retaining portions 31, each having an obliquely quadrilateral trench formed thereon; an abutting post 32 formed in a quadrilateral column shape so as to contact with the two retaining portions 31, such that the rotary shift set 20 and the height adjusting assembly 30 move linearly without rotating radially, so the rotation member 22 will not offset to rotate the handlebar 60 counterclockwise or clockwise, thus obtaining stable adjustment.

    [0048] Referring further to FIG. 12-13, a difference of a shifting structure for a bicycle of a third embodiment from that of the first embodiment comprises: two retaining portions 31, each including a beveled trench formed in a wave shape and having a predetermined tilted angle θ; an abutting post 32 formed in a waved column shape so as to contact with the two retaining portions 31, such that the rotary shift set 20 and the tightness adjusting set 40 move linearly without rotation, and the rotation member 22 moves along the central axis of the abutting post 32 so as to achieve multi-section shifting adjustment, i.e., the rotation member 22 rotates toward the handlebar 60 counterclockwise or clockwise, thus obtaining stable adjustment.

    [0049] Thereby, the shifting structure of the present invention is fixed on any one of the top tube, the down tube, the seat stay, the chain stay, and the front fork tube of the bicycle frame and is applied to adjust the position and the height of the rotary shift set and the height adjusting assembly simultaneously. The shifting structure is simplified and produced easily. Also, the shifting structure is lightweight and operated quickly, and the height adjusting assembly includes the tightness adjusting set mounted thereon so as to pull the steel rope tightly or loosely based on using requirement.
