As shown in fig. 2 and 3, as a preferred embodiment of the present utility model, the fixing member includes:

a mounting groove 11, which is formed in the cutter body 1, wherein the mounting groove 11 comprises a first groove 111, a second groove 112 and a third groove 113 which are communicated with each other;

a locking block 4 which is arranged in the second groove 112 and is matched with the blade 3;

and the push rod 5 is arranged in the third groove 113 and is in sliding connection with the third groove 113, one end of the push rod 5 extends at the tail end inside the cutter body 1, and is close to the inner surface of the side face of the cutter body 1.

In one case of the embodiment, a pin is mounted on the top of the locking block 4, an annular spring is mounted on the pin, when external force acts, the external force is applied to the push rod 5, the locking block 4 can rotate, the push rod 5 pushes the locking block 4, the locking block 4 rotates and compresses the annular spring, the locking block 4 rotates clockwise, the cutting edge 3 is unlocked conveniently, and the cutting edge 3 can be taken down; after the external force is removed, the annular spring rotates anticlockwise, so that the locking block 4 is reset, specifically, the locking block 4 is installed in the second groove 112 and can move, the push rod 5 is installed in the third groove 113 and can slide, preferably, a small hole 6 is arranged on the side face of the cutter body, the small hole 6 is communicated with the tail end of the push rod 5, and when any needle or other tool is inserted into the small hole 6, the push rod 5 is pushed to slide forwards in the third groove 113.
