With the cooperation of the rotating adjustment device and the adjusting device, the workpiece can be linearly moved or rotationally adjusted, which is convenient for all-round chamfering of the workpiece in the later stage.

[0027] In actual use, it is further convenient to chamfer all lateral positions of the workpiece. In this embodiment, the adjusting device includes a threaded rod 11, a square nut 12 and a first motor 13. A rectangular groove 14 is horizontally opened on the top wall of the workbench 1.

When the rack 8 moves, the slide groove 19 provided on the support frame 10 slides, which guides the movement of the rack 8 and prevents the rack 8 from deviating from its motion trajectory.

[0031] In actual use, in order to further prevent the slider 4 from rotating, in this embodiment, a limiting groove 20 for accommodating the slider 4 is opened on the moving seat 2. The limiting groove 20 guides and limits the slider 4, preventing the slider 4 from rotating and preventing the slider 4 from deviating from the motion trajectory.

[0032] In actual use, in order to further ensure the stability of the workbench 1, in this embodiment, support plates 21 are fixedly installed at both ends of the bottom wall of the workbench 1.
