The slider 4 is slidably connected to the guide rail 3 through the cooperation of the limit blocks and the limit grooves, but it is not limited to the above structure, as long as the slider 4 can be moved up and down along the guide rail 3.

[0025] Specifically, there are two groups of rotating mechanisms, which are symmetrically installed on opposite sides of the two sliders 4. The rotating mechanism consists of a stepper motor 6 and a rotating frame 7. The stepper motor 6 is fixed to the side wall of the slider 4 through a support frame 5 and bolts.
