[0020] Reference Fig. 2 The moving mechanism 2 includes a first motor 21, a first threaded rod 22, a threaded sleeve 23, a fixed block 24, a connecting rod 25, a movable block 26, and a bracket 27. The first motor 21 is mounted on the side of the base 1. The output shaft of the first motor 21 rotates through the base 1 and is connected to the first threaded rod 22. The threaded sleeve 23 is threaded onto the first threaded rod 22. The end of the threaded sleeve 23 is fixed to the fixed block 24. The two sides of the fixed block 24 are hinged to the movable blocks 26 through the connecting rod 25.

Through the cooperation of the connecting rod 25, the movable block 26 drives the bracket 27 to move. Thus, the bracket 27 can drive the two placement seats 4 to move towards each other or away from each other, which facilitates the clamping and fixing of different specifications of plates.

[0021] Reference Fig. 3 The lifting mechanism 6 includes a second motor 61, a second threaded rod 62, a threaded block 63, a fixed rod 64, and a sliding sleeve 65.
