Push fork locking structure for hair scissors

Abstract

The invention relates to a push fork locking structure for hair scissors. The push fork locking structure comprises a housing, a push fork, a regulating push key and a lock catch button, wherein the push fork is positioned in the housing and is used for pushing a moving blade; the regulating push key is arranged outside the housing and is used for pushing the push fork to move; the lock catch button moves synchronously with the regulating push key; the push fork is in sliding fit with the housing; the inner side wall of the housing is provided with tooth spaces; the side edges of the push fork are provided with limit control rods matched with the tooth spaces; a locking groove is formed at the positions, which correspond to the lock catch button, on the push fork; a lock catch engaged with the locking groove is arranged on the lock catch button; a returning spring is arranged between the lock catch button and the push fork.

Description

Technical field: [0001] The invention relates to hair cutting equipment, in particular to a locking structure of a push fork of hair cutting scissors. Background technique: [0002] Most of the hair clippers now have the ability to adjust the length of the haircut, which is realized by adjusting the distance between the moving knife and the static knife. The moving knife is pushed by a push fork, but when the push fork moves back and forth to adjust the moving knife, after the position is adjusted in place, there must be a positioning device or mechanism to position the push fork so that the moving knife and the static knife can work normally. In the prior art, the structures of the devices or mechanisms for positioning the push forks are different, and the effects also have their own advantages, but their respective shortcomings are also obvious, and some operations are relatively cumbersome. In some cases, the correlation between the various parts is too strong. As long a...

Problems solved by technology

The moving knife is pushed by a push fork, but when the push fork moves back and forth to adjust the moving knife, after the position is adjusted in place, there must be a positioning device or mechanism to position the push fork so that the moving knife and the static knife can work normally. In the prior art, the structures of the devices or mechanisms used for positioning the push forks are different, and the effects also have their own advantages, but their respective shortcomings are also obvious, and some operations are more cumbersome

In some cases, the correlation between various parts is too strong, as long as there is a problem with one, the whole mechanism has to be disassembled again, which is not only costly but also troublesome to operate
