Trimmer

Abstract

The invention discloses a trimmer. According to the technical scheme, the trimmer is mainly characterized by comprising a machine body, a motor, a tool bit assembly and a blade assembly. The tool bitassembly comprises a tool bit bracket and an installation seat, wherein the tool bit bracket and the installation seat are connected in a hinged manner. The installation seat is provided with an elastic assembly capable of pushing the tool bit bracket to rotate, and the elastic assembly is located on one side of the tool bit bracket in the width direction and can push the tool bit bracket to rotate around a hinge shaft of the installation seat towards the other side. The output end of the motor is provided with a transmission arm, the transmission arm comprises a hinge block, an upper arm anda lower arm. The length directions of the upper arm and the lower arm and the length direction of the hinge block are all inclined. When the motor drives an eccentric wheel to rotate, the motor can drive the transmission arm to swing around the hinged position with the machine body by pushing a butt-joint piece, and a movable blade is driven to perform cutting swing through reciprocating swing ofthe transmission arm and meanwhile through pushing of butt-joint pushing pieces on the two sides of the upper arm. By means of the connection structure of the trimmer, the machining and assembling precision can be lowered, and the trimming direction can be adjusted through a tool bit.

Description

technical field [0001] The invention relates to the technical field of hair clipping equipment manufacturing, more specifically, it relates to a trimmer. Background technique [0002] Electric hair trimmers or barber clippers are generally used by stylists, barbers or individuals to style hair and typically include a handle and a blade portion connected to the handle, wherein the handle has a housing containing an electric motor, in order to receive the electric motor The driving force of the knife head part is usually mounted on the handle. The blade set in the blade assembly includes a fixed blade and a movable movable blade. The movable blade is roughly parallel to the fixed blade and reciprocates in the lateral direction to form a cutting similar to scissors. sports.

AI Technical Summary

Problems solved by technology

[0003] At present, the following problems are found in the use of existing trimmers: 1. After the cutter head is installed on the handle, the output end of the motor is directly connected through the movable blade, so that the rotary drive of the motor can be converted into the reciprocating motion of the movable blade. Sliding, so that the cutting hair of the cutter head is realized

However, during the installation process of the cutter head, the eccentric wheel on the output end of the motor needs to be installed in cooperation with the conversion piece on the movable blade, so the installation of the cutter head requires high assembly accuracy requirements, which limits the installation structure of the motor and the movable blade. The requirements for processing and assembly precision are enhanced, and at the same time, due to the limitation of installation space, it is not conducive to the design of the shell, which is not conducive to improving the design aesthetics of the trimmer

[0004] 2. Even if you adjust the swing direction of the trimmer, there will be areas that are difficult to trim, such as behind the ears or the nape of the neck

This action is inconvenient and often causes discomfort to the user's wrist or hand after continuous use, and reduces the precision and / or efficiency of the trimmer since the blades are not fully in contact with the trimmed area

For this reason, many manufacturers and people of insight have developed and developed, but so far no ideal products have come out.
