Technical Field

The utility model relates to the field of electric hair clippers, in particular to an electric hair clipper with gear adjusting sense and gear self-locking.

Background

Electric hair clippers are commonly known and commonly used tools for repairing hair or animal hair. The structure of the electric hair clipper mainly comprises a shell, wherein a motor and a power supply assembly are arranged in the shell, and a blade assembly driven by the motor is arranged at the front end of the shell. In order to facilitate the use, most of the electric hair clippers in the market are provided with blade adjusting mechanisms, and the positions of the movable blades are adjusted by the blade adjusting mechanisms, so that the effect of cutting hair with different lengths is achieved. However, the prior electric hair clipper is inconvenient to use because the structural arrangement of the blade adjusting mechanism is unreasonable, so that the electric hair clipper is poor in feeling when in gear adjustment and is easy to be touched by mistake for gear adjustment again after the gear adjustment.

Chinese patent publication No. CN213971312U discloses an electric hair clipper with multi-gear adjusting function, including electric hair clipper shell, be located the switch of electric hair clipper shell front end and be located the hair clipper tool bit at electric hair clipper shell top, vertical spout and oblique spout have all been seted up to the both sides at electric hair clipper shell top, wherein the spout that inclines is located the top of vertical spout, the mounting groove has all been seted up to the circumference side of electric hair clipper shell, the slip breach has all been seted up to the both sides of mounting groove inside, the outside of mounting groove is equipped with multi-gear adjusting structure and is located the check ring at multi-gear adjusting structure top, multi-gear adjusting structure includes the adjusting ring. The utility model solves the problems that the existing electric hair clipper needs to be provided with the limiting comb to control the length of the left hair when cutting short hair, but the limiting comb with different lengths needs to be replaced frequently when facing different users, and the problem of trouble is solved. Although the gear is adjusted by the shell, the hand feeling is poor when the gear is adjusted, the adjusted gear cannot be self-locked, and gear false touch is easy to occur.

Chinese patent publication No. CN205148370U provides a gear adjusting device and electric clipper, including casing, push button and push rod assembly on the fuselage, the push rod assembly includes section jack-prop, section spring.
