Of course, the transmission method provided in this embodiment is only for exemplary description and should not be understood as limiting the scope of protection of this application.

[0034] When in use, the driving motor rotates to drive the bidirectional screw to rotate, thereby driving the two sliders to move relative to each other in the slide slot, thereby achieving the purpose of adjusting the distance between the two arc-shaped clamping plates.
