Referring to fig. 11, when the edge of the tooth of the movable cutter head 42 is flush with the edge of the tooth of the stationary cutter head 41, the movable plate 31 can insert the projection 711 of the reed 71 into the recess 731 of the movable rod 73 only when it is moved to the rightmost position on the shield case 23; the movable cutter head 42 is provided with the positioning groove 422, the end part of the torsion spring 43 for fixing the movable cutter head 42 is inserted into the positioning groove 422, after the movable cutter head 42 moves for a certain distance, the end part of the torsion spring 43 is abutted against the inner wall of the positioning groove 422, at the moment, the movable cutter head 42 cannot move continuously, the moving distance of the movable cutter head 42 is limited through the cooperation of the torsion spring 43 and the positioning groove 422, and therefore the limiting position of the movable cutter head 42 can be limited.

after the user takes down the limit comb 5, the reed 71 is not in a bending state, at this time, the user rotates the rotating disc 32 to the rightmost side of the protective shell 23, inserts the protruding block 711 on the side surface of the reed 71 into the groove 731 on the moving rod 73, assembles and fixes the reed 71 and the moving rod 73, rotates the rotating disc 32 again at this time, drives the moving plate 31 to move, simultaneously drives the reed 71 and the moving rod 73 to synchronously move, and drives the movable cutter head 42 to move, thereby realizing the adjustment of the movable cutter head 42.

After the user installs the spacing comb 5 to the side of the housing 11, the plugboard 51 on the side of the spacing comb 5 abuts against the side of the connecting piece 72 and drives the connecting piece 72 to move, the movement of the connecting piece 72 drives the reed 71 to bend, and the bump 711 on the reed 71 is separated from the groove 731 on the moving rod 73, at this time, the moving cutter head 42 cannot be adjusted when the rotating disc 32 rotates.

By the arrangement of the linkage assembly 7, when the limit comb 5 is installed, a user only adjusts the relative position of the limit comb 5 when rotating the rotating disc 32; when the limit comb 5 is detached, a user can rotate the rotating disc 32 to adjust the relative position of the movable cutter 42, so that the problem that the user is injured due to manual adjustment of the movable cutter 42 is avoided, and the user can conveniently adjust the relative position of the movable cutter 42.

The embodiments of this embodiment are all preferred embodiments of the present application, and are not intended to limit the scope of the present application, in which like parts are denoted by like reference numerals. Therefore: all equivalent changes in structure, shape and principle of this application should be covered in the protection scope of this application.
