[0005] Furthermore, the locking boss consists of a column and a platform; the lower end of the column is fixedly connected to the upper surface of the rear part of the cutter head, and the lower surface of the platform is fixedly connected to the upper end of the column. After the column is inserted into the second socket, the lower surface of the platform contacts the upper surface of the front part of the locking slider.

[0006] Furthermore, a slide groove is provided on the upper surface of the shank along its length direction, and an insert block matching the slide groove is provided on the lower surface of the locking slider. The insert block is inserted into the slide groove and can move back and forth linearly along its length direction in the slide groove.

[0007] Furthermore, the cross section of the chute is T-shaped.

[0008] Furthermore, the rear end of the handle is provided with an outwardly convex arc surface.

[0009] Furthermore, a bevel is provided at the front end of the locking slider.

[0010] The beneficial effects of the present invention are as follows: after use, only the blade head needs to be discarded, and the handle can be reused, which reduces waste; the blade head of the present invention can be quickly connected to the handle, and the replacement and disassembly speed is fast and efficient; the present invention has a simple structure and low manufacturing cost, which reduces waste and is also easy to store and preserve. One handle can be equipped with several blade heads, which are small in size, easy to store and preserve, and also easy to carry outside. BRIEF DESCRIPTION OF THE DRAWINGS
