[0036] Embodiment two
[0037] Referring to the figure, the transmission assembly comprises a first gear 7 and a second gear 8 that are engaged with each other, the second gear 8 is sleeved on the connecting piece 2 and is screwed to the connecting piece 2, the inner side of the second gear 8 is provided with an internal thread, and the outer side of the connecting piece 2 is provided with an external thread that matches the internal thread in this embodiment. Since the positions of the first gear 7 and the second gear 8 are relatively fixed inside the inner cavity, when the first gear 7 rotates, the second gear 8 rotates accordingly, thereby driving the threaded connecting piece 2 to protrude further from the carrier 1 or to retract back into the carrier 1. The fixing assembly comprises a third abutting block 9 for abutting against the connecting piece 2, the third abutting block 9 is in a cylindrical shape and is rotatably connected to the carrier 1. A protruding block 90 for abutting against the connecting piece 2 is provided on the curved outer side of the third abutting block 9. The carrier 1 is provided with a mounting groove 19 for mounting the third abutting block 9, and a fan-shaped groove 191 is provided outside the mounting groove 19 for accommodating the protruding block 90 and providing space for the protruding block 90 to approach or move away from the connecting piece 2.

A polygonal hole 91 is provided in the middle of the third abutting block 9, which corresponds to the center of the end face of the first gear 7. The third abutting block 9 is a resilient member. After adjustment is completed, the third abutting block 9 is rotated, and the protruding block 90 of the third abutting block 9 abuts against the connecting piece 2. The protruding block 90 is in a circular arc shape, and as the third abutting block 9 is gradually rotated to one side wall of the fan-shaped groove 191, the most protruding part of the protruding block 90 abuts against the connecting piece 2 to fix the connecting piece 2. The third abutting block 9 can be made of plastic material, which utilizes the elasticity of plastic itself. The center of the end face of the first gear 7 is provided with a polygonal groove 92, which is smaller than the polygonal hole 91, so that the same opening 11 can be used for the operation of the first gear 7 and the third abutting block 9. This can reduce the number of openings 11 of the carrier 1, and people can operate through the same opening 11. The opening 11 of this embodiment is provided as one, and is further blocked from the internal structure under the shielding of the first gear 7.
[0038] In summary, the connecting piece 2 is arranged in the carrier 1, one end of which protrudes from the top surface of the carrier 1, and the other end can be arranged to protrude from the bottom surface of the carrier 1 or can be hidden in the inner cavity without protruding. At this time, the protruding block 90 on the third abutting block 9 does not abut against the connecting piece 2. A small tool is inserted into the opening 11 and inserted into the polygonal groove 92 of the first gear 7, and the first gear 7 is twisted, thereby rotating the second gear 8 and making the connecting piece 2 that is screwed to the second gear 8 protrude further from the carrier 1 or retract back into the carrier 1. After adjustment is completed, a large tool is replaced, that is, a tool that matches the polygonal hole 91 is used to rotate the third abutting block 9, so that the protruding block 90 is rotated to the connecting piece 2 and abuts against the connecting piece 2 to achieve the purpose of fixation.
[0039] The above embodiments are the preferred embodiments of the present application, and any similar structure and equivalent changes made should belong to the protection scope of the present application.
