[0029] Since the support member 1 is cylindrical, hollow inside and open towards one side, a partition plate 11 is provided inside the support member 1. The partition plate 11 divides the space of the support member 1 into two parts. One side of the partition plate 11 is provided with a support rod 2. The end face of the support rod 2 is rotatably connected to the support member 1. The support rod 2 is strip-shaped, and a chamfering tool 3 is provided on the support rod 2.

The guide rod 13 is arc-shaped and has a circular cross-section. The guide rod 13 is inserted through the support rod 2. A reset member 14 is sleeved on the guide rod 13. The reset member 14 is a spring. One end of the reset member 14 is fixedly connected to the support member 1, and the other end of the reset member 14 is fixedly connected to the support rod 2. Thus, when the regulating member 42 moves left and right, the support member 1 is always in contact with the regulating member 42 to prevent shaking. A second rod 51 is threadedly connected to the support member 1. The second rod 51 is inserted through the first rod 41 but does not contact the second rod 51. The rotation of the first rod 41 does not affect the rotation of the second rod 51. A height plate 52 is provided on the end face of the first rod 41.
