[0028] The gripping component includes a positioning rod 2, which is placed inside the connecting frame 1. The top and bottom surfaces of the connecting frame 1 are provided with sliding grooves 9. Sliding blocks 3 are placed inside the two sliding grooves 9. Electric push rods 4 are fixedly installed on the side of the two sliding blocks 3 away from the positioning rod 2. The output ends of the two electric push rods 4 pass through the two sliding blocks 3 and extend into the interior of the connecting frame 1.

The output ends of the two electric push rods 4 pass through the two through holes and are fitted with the gap.

[0030] Specifically, the sliding connection between the sliding block 3 and the sliding groove 9 drives the clamping plate 5 to move, thereby adjusting the position of the clamping plate 5.
