[0030] The specific usage and function of this embodiment are as follows:

[0031] In the present utility model, Figure 1 As shown, the tool body 1 is in the assembled state, at this time the regular hexagonal prism of the detachable tool head 3 is inside the regular hexagonal groove of the movable lock cylinder 5, the state is as shown in FIG. Figure 2 As shown, the detachable cutter head 3 cannot be rotated on the carrier cutter bar 2, thereby achieving the anti-loosening assembly of the carrier cutter bar 2 and the detachable cutter head 3; Figure 1 As shown, when the detachable cutter head 3 is disassembled, the rotating carrier cylinder 4 is rotated to engage with the carrier cutter rod 2, so that the rotating carrier cylinder 4 is raised through the thread engagement, and the rotating carrier cylinder 4 drives the movable lock cylinder 5 to rise synchronously through the bearing, so that the movable lock cylinder 5 rises and separates from the outside of the regular hexagonal prism of the detachable cutter head 3, and the state is as shown in FIG. Figure 4 As shown, the anti-loosening state of the movable lock cylinder 5 on the detachable cutter head 3 is released, so that the detachable cutter head 3 can be rotated inside the threaded blind hole of the carrier cutter rod 2, and then the detachable cutter head 3 is rotated by a tool to engage with the thread of the carrier cutter rod 2, so that the detachable cutter head 3 is lowered and disengaged from the threaded blind hole of the carrier cutter rod 2 through the thread engagement, thereby realizing the disassembly of the detachable cutter head 3.

[0032] Example 2:

[0033] The difference from Example 1 is that the bottom end surface of the threaded column carrying the tool rod 2 can also be set to a frosted surface, thereby increasing the friction between the bottom end surface of the threaded column carrying the tool rod 2 and the detachable tool head 3, preventing the detachable tool head 3 from loosening.

[0034] Example 3:

[0035] The difference from Example 1 is that the regular hexagonal groove of the anti-rotation stud 6 can also be set as a regular heptagonal groove, so that the anti-rotation stud 6 can only be rotated by a special tool that cooperates with the regular heptagonal groove, preventing non-staff from rotating and disassembling the anti-rotation stud 6.
