[0025] The lower end of the support shaft 2 is fixedly connected to a mounting frame 8, and a motor 9 is fixedly installed on the vertical part of the mounting frame 8. The output shaft of the motor 9 is rotatably connected to the mounting frame 8, and the output shaft of the motor 9 is fixedly connected to a positive and negative threaded screw 10. The positive and negative threaded screw 10 is rotatably connected to the mounting frame 8. The outer side of the positive and negative threaded screw 10 is connected to two symmetrically distributed clamping plates 11 through threads, and each clamping plate 11 is slidably connected to the mounting frame 8. A clamping hole 12 is opened on the inner wall of the mounting frame 8, and an elastic sheet 13 is bonded to the inside of the clamping plate 11, and a clamping ball 14 is bonded to the other end of the elastic sheet 13, and the clamping ball 14 is slidably connected to the clamping hole 12.

[0026] See also Figure 1 , Figure 2 The upper end of the support plate 1 is fixedly connected with a mounting piece, and two mounting pieces are provided. The two mounting pieces are symmetrically distributed on the support plate 1. Through the setting of the mounting pieces, the clamp can be subsequently installed and used. The tooth plate 6 is slidably connected to the support plate 1, and the tooth plate 6 is meshed with the gear 3. Through the meshing relationship, when the tooth plate 6 moves, the gear 3 can be rotated.

[0027] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 A friction groove is provided on the surface of the clamping plate 11, and a plurality of friction grooves are provided, and the plurality of friction grooves are evenly distributed on the clamping plate 11.

[0028] The specific implementation process of the utility model is as follows: when the special fixture of the palletizing robot needs to be used, the cylinder 7 is started to drive the telescopic end to move, so as to push the tooth plate 6 to move, so as to drive the guide block 5 to slide along the surface of the guide rod 4.

Under the action of force, the clamping ball 14 slides along the inner wall of the mounting frame 8. When the clamping ball 14 slides into the next clamping hole 12, the elastic sheet 13 resumes its deformation to push the clamping ball 14 into the clamping hole 12, and limits the position of the clamping plate 11 to avoid the problem of excessive clamping of the clamping plate 11.
