Kind Code:

Abstract:
A guide comb adjustment structure and a hair clipper. The guide comb adjustment structure comprises an adjustment wheel (1), a pushing plate (2), and a guide comb (3); the guide comb (3) is connected to the adjustment wheel (1) by means of the pushing plate (2); the inner wall of the adjustment wheel (1) is provided with a plurality of spiral grooves (11) which are communicated with each other; the pitch of each spiral groove (11) is different; the pushing plate (2) is provided with a guide post (21); the plurality of spiral grooves (11) alternatively cooperate with the guide post (21), so that when the adjustment wheel (1) rotates, the pushing plate (2) is driven to move in a front-back direction, and the pushing plate (2) drives the guide comb (3) to move synchronously. A plurality of spiral grooves (11) having different pitches and communicated with each other are provided in the adjustment wheel (1), so that the protruding length of the guide comb (3) can be finely adjusted, and the range of the protruding length of the guide comb (3) can be expanded in a case where the total rotation stroke of the adjustment wheel (1) is constant; in addition, on the basis that the design structure of the spiral grooves (11) does not need to be adjusted, the difference between gears of the protruding length of the guide comb (3) can be adjusted by only adjusting the rotation angle of the adjustment wheel (1) when said adjustment wheel is rotated by one gear, and thus, higher universality is achieved.
