[0043] Embodiment three;

[0044] See also Figure 6 The fixing assembly 2 includes a support frame 21, a fastening bolt 23, a clamping plate 25 and a connecting plate 27. The support frame 21 is fixed to the bottom end of the disc 1, and the connecting plate 27 is fixed to the bottom end of the support frame 21. A clamping plate 25 is slidably provided on one side of the connecting plate 27, and fastening bolts 23 are inserted through threads at both ends of the clamping plate 25.

[0045] In the utility model, the working steps of the device are as follows:

[0046] First, use the fixing component 2 to fix the device to the external table surface, then pass the object to be processed through the channel square groove 9, and then rotate the push rod 10 to push the second movable plate 6 to move close to the first movable plate 5, and the second rack 8 moves synchronously with the second movable plate 6. The movement of the second rack 8 causes the gear 13 to mesh and rotate. The rotation of the gear 13 causes the first rack 7 to mesh and move in the opposite direction of the second rack 8, and the first rack 7 drives the first movable plate 5 to move, and finally the first movable plate 5 and the second movable plate 6 move in an aligned manner at the same time. After the two sets of clamping rollers 12 move in an aligned manner with the first movable plate 5 and the second movable plate 6 and form a certain clamping force on the object, the rotation of the push rod 10 can be stopped. At this time, the object can be processed. For objects with a longer length, force can be directly applied to slide them along the inside of the channel square groove 9. Under the rotation of the two sets of clamping rollers 12, the force of manual force can be reduced to ensure that the object can move back and forth for easy processing.

[0047] If the angle of the object needs to be adjusted, such as when processing other surfaces of the object, the fasteners 4 can be rotated first to disengage one end of the two sets of fasteners 4 from the reserved holes 11, and then the supporting turntable 3 is rotated along the front of the disc 1. After it is rotated to a suitable angle, the fasteners 4 can be re-inserted through the supporting turntable 3 into the reserved holes 11 at the appropriate position.

[0048] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
