The rear side of the adjustment plate 8 is installed with Multiple limiting rollers 11, and convex strips are fixedly installed on the top and bottom surfaces of the guide frame 2. The limiting rollers 11 are rollingly connected to the outer side of the convex strip to ensure the stable movement of the adjustment plate 8. A groove is provided on the guide frame 2, and a first rack is provided on the inner wall of the groove. Two first motors 4 are symmetrically installed on the front side of the adjustment plate 8, and the output ends of the first motors 4 are provided with second gear pieces 15. The second gear pieces 15 are located on the rear side of the adjustment plate 8, and the second gear pieces 15 and the first rack mesh with each other to drive the movement of the adjustment plate 8.

[0023] Specifically, two adjusting brackets 3 are symmetrically installed, and the two adjusting brackets 3 are movably connected to the front side of the adjusting plate 8. A second rack is installed on one side of the adjusting bracket 3, and the outer side of the second rack is engaged with a first tooth piece 9 to control the up and down movement of the adjusting bracket 3. A driving end is provided on the rear side of the first tooth piece 9, and the driving end is rotatably connected to the rear side of the adjusting plate 8. A belt 14 is connected between the two driving ends to achieve synchronous lifting and lowering of the two adjusting brackets 3, and a second motor 10 is installed on one of the driving ends, and the second motor 10 is provided on the rear side of the adjusting plate 8.

[0024] Furthermore, the lifting plate 5 is fixedly installed between the bottom ends of the two adjustment brackets 3, the clamping motor 12 is installed in the middle position of the top surface of the lifting plate 5, the output end of the clamping motor 12 passes through the bottom surface of the lifting plate 5, and the pulling piece 16 is located on the bottom side of the lifting plate 5, and it is fixedly installed on the output end of the clamping motor 12.

[0025] In this embodiment, two arc-shaped clips 6 are symmetrically installed, a slide groove is opened on the bottom surface of the lifting plate 5, and a slider is installed on the arc-shaped clip 6. The slider is movably connected in the slide groove. A driving piece 13 is connected between the two arc-shaped clips 6 and the ends of the pulling piece 16.
