[0028] In the embodiment of the utility model, the first motor 3 is started, and the start of the first motor 3 can drive the one-way screw 4 to rotate. Since the moving block 5 is threadedly connected to the outer ring of the one-way screw 4, starting the first motor 3 can drive the moving block 5 to move left and right.

[0029] Embodiment 2:

[0030] Please refer to Figure 1-4 A second limiting rod 14 is fixedly connected to the inner cavity of the lifting frame 9, and the second limiting rod 14 is inserted into the inner cavity of the connecting block 12. Two groups of second limiting rods 14 are provided and are symmetrically distributed with the connecting block 12.
