Length-adjustable electric hair trimmer

Abstract

The invention relates to a length-adjustable electric hair trimmer which comprises a body assembly and a head assembly. The body assembly comprises a shell, a battery cover, a motor, a motor rack, a battery and a circuit assembly. The head assembly comprises a head, a head cover, a cutter assembly, a swing rod, a combing sheet, an adjusting button and clamping points. The motor rack is mounted inan inner cavity of the shell; the motor is clamped at the top end of the inner cavity of the shell; the cutter assembly is tightly mounted at the top end of the head; holes are formed in two sides ofthe head; the adjusting button is mounted in each of the holes and can slide up and down in the hole; the combing sheet is arranged at the upper portion of the head in a sleeving manner, hook heads are arranged at two ends of the combing sheet to hook the adjusting button and to be linked with the adjusting button; and slots are formed in the holes in two sides of the head, the clamping points aremounted in the slots, the clamping points are elastic, and the sticking points of the clamping points clamp the adjusting button to limit the upper and lower positions of the adjusting button.

Description

technical field [0001] The invention relates to a hair trimmer, in particular to an electric hair trimmer with adjustable length. Background technique [0002] People have hair on their body surface, which grows continuously and needs to be trimmed frequently. Hair trimmers are mainly composed of handles and blades. There are manual and electric ones; The motor installed in the handle drives the moving knife in the blade group to reciprocate, the teeth of the moving knife and the teeth of the fixed knife are constantly misaligned, and the hair entering between the teeth is cut; since the moving knife is reciprocating at high speed , Improper operation may accidentally injure the skin, so electric hair trimmers are generally equipped with combs to protect the skin; the distance from the top of the comb to the moving knife determines the length of the trimmed hair, and you want to trim different lengths Some of the hair can be achieved by replacing the combs of different spec...

[0002] People have hair on their body surface, which grows continuously and needs to be trimmed frequently. Hair trimmers are mainly composed of handles and blades. There are manual and electric ones; The motor installed in the handle drives the moving knife in the blade group to reciprocate, the teeth of the moving knife and the teeth of the fixed knife are constantly misaligned, and the hair entering between the teeth is cut; since the moving knife is reciprocating at high speed , Improper operation may accidentally injure the skin, so electric hair trimmers are generally equipped with combs to protect the skin; the distance from the top of the comb to the moving knife determines the length of the trimmed hair, and you want to trim different lengths Some of the hair can be achieved by replacing the combs of different specifications. This operation is not only troublesome but also wasteful. It can also be realized by adjusting the distance between the comb and the moving knife. The existing technical solutions are all controlled by the large switch in the middle of the front surface. The linkage comb produces displacement. Because the large control switch is in the middle, the thickness of the machine head increases, and it is inconvenient to trim the ears or other corners. Moreover, the large control switch is on one side, the torque is unbalanced, the blocking force is large, and the control is inconvenient.
