In addition, it should be noted that only the parts related to the utility model are shown in the drawings for convenience of description, not all.

[0030] Referring to Figures 1-3 The utility model discloses a kind of hair clippers with laser line beam auxiliary, including frame 1, the razor assembly 2 of being set in the front of frame 1, the razor assembly 2 includes the cutting part 23 for cutting hair in front end, cutting line 20 is formed with over cutting part 23;Frame 1 is provided with positioning module 3, positioning module 3 can emit several positioning light beams 31, positioning light beam 31 is emitted from positioning module 3, several positioning light beams 31 evenly pass through cutting line 20, and project in the front of cutting part 23.

[0031] With reference to Figure 3 , the razor assembly 2 includes a fixed blade 21 and a moving blade 22, and the cutting part 23 includes a fixed blade tooth tip 210 formed at the front end of the fixed blade 21 and a moving blade tooth tip 220 abutting the fixed blade tooth tip 210 at the front end of the moving blade 22;

[0038] With reference to Figures 6-8 One side surface of the rotating block 40 is provided with a trigger column 400, the lower end of the trigger module 41 is provided with a trigger piece 410, when the rotating block 40 rotates, the trigger column 400 can abut and press the trigger piece 410, so as to trigger the positioning module 3 to emit the positioning light beam 31, at this time, the linkage column 401 drives the fixed blade 21 to move to the state that the fixed blade tooth tip 210 and the moving blade tooth tip 220 are in the same line. Preferably, the gear device 4 is further provided with an adjusting gear handle 42 connected to the rotating block 40.

[0039] Further, through the mechanical linkage of the gear device 4 and the trigger module 41, the intelligent cooperation of the fixed blade 21 adjustment and the positioning light beam 31 start-stop is realized, when adjusted to the state that the fixed blade tooth tip 210 and the moving blade tooth tip 220 are in the same line, the trigger piece 410 automatically activates the projection of the positioning light beam 31, the light beam line of the positioning light beam 31 is aligned with the cutting line 20 on the current fixed blade tooth tip 210.
