Multiple working plates 2 can rotate circumferentially along the same axis to adjust the direction of the concave surface of the working plate 2, so that the arc-shaped concave surface formed by multiple working plates 2 faces / away from the handle 1.

[0025] In this embodiment, there are two work panels 2, which can be joined together to form a semicircle. This embodiment has a simple structure and can be adjusted to be used for chamfering arc-shaped external or internal corners. It is low in cost. By joining the work panels 2 together to form an arc, it can avoid the impact of labor differences on construction quality and ensure uniform chamfer size and flatness.
