Preferably, the keyway 26 is externally covered by a dust ring 27.

Preferably, the tool 1 is fixed on the tool seat 28, and a second spring 29 is arranged in the axial direction of the tool seat 28 and the tool bar 21, so that the axial positions of the tool seat 28 and the tool bar 21 are adjustable; the positioning element 3 is connected to the knife bar 21 by means of a bearing 4.

Preferably, the bearing 4 is sleeved outside the cutter bar 21, a third adjusting hole is formed inside the cutter bar 21, and the cutter holder 28 extends into the third adjusting hole and is abutted against the bottom of the third adjusting hole through a second spring 29; the radial direction of the tool seat 28 and the tool shank 21 is connected by a set screw.

As shown in fig. 2, at least two abutting surfaces 281 are cut on the outer periphery of the tool holder 28, when there are two abutting surfaces 281, the two abutting surfaces 281 are arranged in parallel, and an included angle between the abutting surfaces 281 and the axis of the tool holder 28 is an acute angle; along the axial direction of the tool apron 28, at least two set screws are abutted on each abutting surface; by using the structure, after the fastening screw presses the abutting surface, the cutter holder 28 is not easy to move in the axial direction of the cutter bar 21, and the fixing of the axial positions of the cutter holder 28 and the cutter bar 21 is more reliable.
