Description
Technical field
The present invention relates to a kind of haircut equipment, relate to a kind of adjustment structure of hair scissors torsion spring torsion specifically.
Background technology
Along with development of technology, the performance of hair scissors and structure all are greatly improved and improve.In the cutter head structure of hair scissors, need make both keep in use being close to through compressing structure between cutting blade and the fixed blade, this compressing generally all is to adopt stage clip or torsion spring to realize; The stage clip compressing structure can be good at realizing that cutting blade and fixed blade be close to, and can realize the compressing degree between cutting blade and the fixed blade through regulating bolt, but this structure more complicated that compresses mode; Make manufacturing, installation and the maintenance of hair scissors all bother very much, therefore, for avoiding in cutter head, being provided with too complex installation structure; Increasing hair scissors has adopted the compressing structure of torsion spring type; Though this compressing structure is fairly simple, can not adjust the compressing degree between cutting blade and the fixed blade, long-time the time after; The torsion of torsion spring can change; Cause also can producing between cutting blade and the fixed blade certain becoming flexible, will influence the shearing sharpness of cutting blade and fixed blade like this, thereby influence the serviceability of hair scissors.
Summary of the invention
For solving above-mentioned technical problem, the present invention provides a kind of adjustment structure of simple in structure, the hair scissors torsion spring torsion that helps improving the hair scissors serviceability.
Technical scheme of the present invention is, a kind of adjustment structure with hair scissors torsion spring torsion of following structure is provided, and it comprises quiet knife assembly, moving knife assembly, shell and torsion spring; Quiet knife assembly and moving knife assembly are close to, and it also comprises adjusting bracket, and adjusting bracket is installed on the shell through adjusting device; Adjusting device drives adjusting bracket and moves back and forth; Torsion spring is installed on the adjusting bracket, and an end and the adjusting bracket of torsion spring offset, and the other end and moving knife assembly offset moving knife assembly and quiet knife assembly are compressed.
After adopting said structure, the present invention has following beneficial effect and remarkable advantage:
Under normal circumstances need be to the adjusting bracket control, when the torsion of torsion spring was not enough to guarantee that moving knife assembly and quiet knife assembly keep being close to, adjusting device can drive regulating block and move; Can realize adjusting through moving of adjusting bracket to torsion spring torsion; According to actual use needs, the position of regulating block is adjusted, make the torsion of torsion spring free variation; Thereby make between moving knife assembly and the quiet knife assembly and remaining suitable compressing, make hair scissors have the effect of getting a haircut preferably.
Preferable, described adjusting device comprises stage clip and push rod, the both sides of outer casing inner wall bottom are provided with guide pillar; Compression spring sleeve is outside guide pillar; The both sides of adjusting bracket are provided with trepanning, and adjusting bracket is enclosed within on the guide pillar and compresses stage clip, and the upper end of guide pillar is provided with blocks the block that adjusting bracket breaks away from from guide pillar; Push rod is threaded with the top of shell, and the lower end of push rod reaches in the shell and is connected with adjusting bracket, and the upper end is positioned at outside the shell.Under the normal situation of torsion spring torsion, need not regulate torsion spring, this moment, the top that is positioned at guide rod, position of regulating block was located by stage clip and block; Position when this position is product export, after long-time the use, the torsion of torsion spring changes and when needing to regulate torsion; Just rotate push rod, push rod moves down the regulating block pressed downward, and it is big that the torsion of torsion spring becomes; Make to remain between moving knife assembly and the quiet knife assembly and be close to; Thread connecting mode between push rod and the shell makes that adjusting is very simple and convenient, and the guide pillar structure helps regulating block and in moving process, keeps stable, and the feasible regulation and control to regulating block of stage clip have better adjusting function.
Preferable, adjusting bracket is provided with the groove that is used to put the torsion spring main body, and the centre position of adjusting bracket is provided with pit, and the lower end of push rod is against in the pit, and the front side of adjusting bracket also is provided with the indent that is used to fasten the torsion spring arm.This structure helps improving the stability that cooperates between regulating block and torsion spring, the push rod, and the installation of torsion spring is more stable, cooperates the location accurately between push rod and the regulating block.
Preferable, described shell comprises loam cake and lower cover, cover under guide pillar is positioned at, on cover and be provided with screwed hole, push rod is a screw rod, push rod and on the screwed hole that covers screw.Shell is made up of two parts, is convenient to assembling like this, and push rod covers on the position, and the upper end of push rod reaches loam cake and both had been convenient in use the torsion of torsion spring regulated and control so outward, can not impact hairdresser or haircut person again.
Preferable, the upper end of push rod also is provided with knob.Be convenient to like this push rod is operated.
