The second outer cylinder 21 is a hollow cylindrical body, and an insertion part 211 is disposed on one end of the second outer cylinder 21 corresponding to the opening 111 of the first outer cylinder 11. The transmission screw rod 22 is received in the second outer cylinder 21, and has a passive end 221 protruding from the insertion part 211, and a plurality of outer teeth 221A engaged with each of the inner teeth 121A are formed on an outer edge of the passive end 221. The insertion part 211 is longitudinally extended with a plurality of connection pieces 212 corresponding to each of the elastic latching hooks 113, and each of the connection pieces 212 is annularly disposed at an outer periphery of the passive end 221. In some embodiments, the actuating unit 20 further includes a bearing 23. The bearing 23 is adapted to sheathe the transmission screw rod 22, and a plurality of inner reverse hooks 212A are concavely disposed on an inner edge of each of the connection pieces 212. Each of the inner reverse hooks 212A and the insertion part 211 jointly clamp and fasten the bearing 23 to allow a central location of transmission screw rod 22 to be kept.

[0016] Details are provided as follows. The actuating unit 20 further includes a moveable inner cylinder 24. The moveable inner cylinder 24 is moveably disposed in the second outer cylinder 21, and the moveable inner cylinder 24 is engaged with and connected to the transmission screw rod 22 to make the transmission screw rod 22 drive the moveable inner cylinder 24 to retractably move relative to the second outer cylinder 21. The moveable inner cylinder 24 has a fasten end 241 exposed outside the second outer cylinder 21. The fasten end 241 has a rotary connector 241A, and the rotary connector 241A has a fasten hole 241B to fasten the actuating unit 20 on the door frame or the vehicle frame.

[0017] Please refer to FIG. 1 and FIG. 2, the actuating unit 20 is connected to the driving unit 10. In some embodiments, the insertion part 211 of the second outer cylinder 21 is inserted to the opening 111 of the first outer cylinder 11, thus the passive end 221 of the transmission screw rod 22 may be engaged with the transmission slot 121 of the driver 12, and each of the connection pieces 212 is correspondingly hooked with each of the elastic latching hooks 113 to longitudinally lock the driving unit 10 and the actuating unit 20. As such, a connecting and fastening relation may be achieved between the driving unit 10 and the actuating unit 20, the transmission slot 121 of the driver 12 and the passive end 221 of the transmission screw rod 22 are connected for transmitting power, thus the driver 12 drives the transmission screw rod 22 to rotate to make the moveable inner cylinder 24 retractably move.

Each of the hook parts 113C is correspondingly hooked with each of the outer reverse hooks 212B to longitudinally block each of the connection pieces 212. In some embodiments, every two of the elastic latching hooks 113 are defined as a set to latch one of the corresponding connection pieces 212 (in other words, the amount of the elastic latching hooks 113 is double comparing to the amount of the connection pieces 212), the two elastic latching hooks 113 defined as the set are oppositely disposed, thus the hook parts 113C of the two elastic arms 113B are jointly latched with the outer reverse hook 212B of the corresponding connection piece 212. The present disclosure is not intended to be limiting, for example there are elastic latching hooks 113 as many as the connection pieces 212 as long as a latching and restraining effect may be effectively provided.

[0019] The insertion part 211 of the second outer cylinder 21 is further extended with a plurality of positioning columns 213, and the driver 12 is concavely formed with a plurality of positioning holes 122 surrounding the transmission slot 121. In some embodiments, each of the positioning columns 213 and each of the connection pieces 212 are arranged at intervals, but here is not intended to be limiting. Each of the positioning columns 213 is respectively inserted in each of the corresponding positioning holes 122 to achieve a positioning effect. As such, when the transmission slot 121 of the driver 12 drives the transmission screw rod 22 to rotate, the second outer cylinder 21 of the actuating unit 20 may be prevented from being driven to rotate. In some embodiments, there are four positioning columns 213, but here is not intended to be limiting. For example there may be two, three, four or more than four of positioning columns 213, as long as the positioning effect may be achieved and a rotating situation may be prevented.

[0020] Please refer from FIG. 5 to FIG. 9, which are schematic views showing the actuating unit 20 and the driving unit 10 being assembled.

When the insertion part 211 is inserted in the opening 111, each of the connection pieces 212 pushes a top end and a bottom end of the two corresponding elastic arms 113B (not shown in figures), thus each of the connection pieces 212 may be inserted between the two sets of corresponding elastic latching hooks 113. Please refer from FIG. 7 to FIG. 9, when the actuating unit 20 is inserted and positioned, the insertion part 211 of the second outer cylinder 21 is latched in the opening 111 of the first outer cylinder 11, the passive end 221 of the transmission screw rod 22 is engaged with the transmission slot 121 of the driver 12, and each of the positioning columns 213 is correspondingly inserted in each of the positioning holes 122 to prevent the second outer cylinder 21 from rotating as shown in FIG. 7. The outer reverse hook 212B of each of the connection pieces 212 is latched and blocked by the hook parts 113C of the two corresponding elastic arms 113B as shown in FIG. 8 and FIG. 9, thus the actuating unit 20 and the driving unit 10 may be longitudinally locked and assembled.

[0021] Please refer from FIG. 10 to FIG. 12, which disclose a second embodiment of the present disclosure, a difference between the first embodiment and the second embodiment is that each of the positioning columns 213 is extended to a distal end of each of the connection pieces 212, and each of the connection pieces 212 and the corresponding positioning column 213 and the corresponding positioning hole 122 may be aligned on the same linear line. Please refer to FIG. 10, before the actuating unit 20 and the driving unit 10 are assembled, the passive end 221 of the transmission screw rod 22 is aligned with the transmission slot 121 of the driver 12, each of the positioning columns 213 is aligned with each of the positioning holes 122. Because the connection pin 212, the corresponding positioning column 213 and the corresponding positioning hole 122 are aligned on the same linear line, each of the connection pieces 212 is aligned with each of the corresponding elastic latching hooks 113. Please refer to FIG. 11 and FIG. 12, after the actuating unit 20 is assembled with the driving unit 10, the outer reverse hook 212B of each of the connection pieces 212 is latched and blocked by the hook parts 113C of the two corresponding elastic arms 113B, and each of the positioning columns 213 located at the front may be inserted in each of the corresponding positioning holes 122. Accordingly, the design provided by the second embodiment may effectively simplify the whole structure, reduce the assembly error and lower the production cost, and the same technical feature provided in the first embodiment may be kept.
