The disc 13 is elastically connected to the rotating plate 6 through the spring 9. After pressing the rotating plate 6, the spring 9 can be squeezed. At the same time, after the rotating plate 6 is squeezed by the reverse force of the squeezed spring 9, the rotating plate 6 is limited by the limiting plate 14 so that the rotating plate 6 always squeezes the limiting plate 14 and cooperates with the rubber sleeve 10 to increase the friction between the rotating plate 6 and the rubber sleeve 10 and the limiting plate 14, thereby preventing the vibration during the processing of the workpiece from causing the worm wheel 4 and the worm 7 to rotate, thereby improving the stability.

After the pull rod 31 is pulled to stretch the second spring 36, the slide bar 35 can slide out of the limit groove 37 to release the limit of the roller 32. At the same time, the reverse force of the stretched spring 36 allows the pull rod 31 to reset and drive the slide bar 35 to reset and slide into the limit groove 37 to limit the roller 32. The second spring 36 is sleeved on the rear end outer wall of the pull rod 31.

[0039] Working principle: When clamping an uneven workpiece, the limit rod 34 can be pulled to squeeze the spring three 38, and the limit rod 34 slides out of the circular groove 39. At this time, the support plate 33 can be moved. After the support plate 33 is adjusted to an appropriate height, the reverse force of the squeezed spring three 38 drives the limit rod 34 to reset and slide into the circular groove 39 to limit the support plate 33. At this time, the pull rod 31 is pulled to drive the slide rod 35 to move and at the same time stretch the spring two 36, so that the slide rod 35 slides out of the limit groove 37. At this time, the roller 33 can be rotated.

The plurality of rollers 32 are connected to each other by a plurality of clamping plates. The plurality of rollers 32 are connected to each other, and the plurality of clamping plates are connected to each other. The plurality of rollers 32 are connected to each other, and the plurality of clamping plates are connected to each other.

[0040] When it is necessary to process in different directions, the rotating plate 6 can be rotated to drive the worm 7 to rotate, and the worm 7 is meshed with the worm wheel 4 to make the worm wheel 4 rotate. After the workpiece is rotated to the appropriate direction, the limiting plate 14 is rotated at this time, and the rotating plate 6 is pressed to make the rotating plate 6 slide into the rubber sleeve 10 and contact the rubber sleeve 10 after squeezing the spring 9. At the same time, the rotating plate 6 is squeezed by the rubber sleeve 10. At this time, the limiting plate 14 is rotated to limit the rotating plate 6 to prevent the rotating plate 6 from slipping out. At this time, the rotating plate 6 can be limited in the rubber sleeve 10 and the spring 9 is used to squeeze the rotating plate 6 so that the rotating plate 6 always squeezes the limiting plate 14, thereby increasing the friction of the rotating plate 6, thereby preventing vibration from being generated during the processing of the workpiece, causing the worm wheel 4 and the worm 7 to rotate, thereby increasing stability and improving the processing effect.
