[0018] Furthermore, the limiting unit includes a servo motor 17, a synchronous wheel 18, a first lead screw 8.1 and a second lead screw 8.2. The servo motor 17 is fixedly mounted on the docking platform 1. The output shaft of the stepper motor 16 is connected to the synchronous wheel 18 through a first synchronous belt. The synchronous wheel 18 is connected to the first lead screw 8.1. The first lead screw 8.1 is connected to the second lead screw 8.2 through a second synchronous belt 13. The first lead screw 8.1 and the second lead screw 8.2 are respectively threadedly connected to the first transmission frame 4 and the second transmission frame 5. The servo motor 17 drives the first lead screw 8.1 and the second lead screw 8.2 to rotate synchronously through the synchronous wheel 18 and the second synchronous belt 13, thereby driving the second transmission frame 5 to move horizontally.

[0019] Furthermore, the limiting unit also includes guide shafts 9, one end of the two guide shafts 9 is respectively fixed on the first transmission frame 4, and the other end is fixed on the fixed platform 2 on the docking frame 1. The two guide shafts 9 are respectively arranged on both sides of the first screw 8.1 and the second screw 8.2 and are slidably connected to the second transmission frame 5.
