Description

The direction control structure of the ratchet of improvement

Technical field

The present invention relates to the direction control structure that a kind of field of hand is used for the ratchet of fastening, connection, dismounting or clamping tools, particularly relate to a kind of direction control structure () of ratchet of the improvement with simple and easy installation function.It is to utilize control to the effect of pulling of the top of piece and elastic component, makes it reach the direction control structure of ratchet control to the ratchet of effect because of the effect that is subjected to different top and pulls, and becomes a kind of new design that quite has practicality and progressive, is suitable for the industrial circle wide popularization and application.

Background technology

Existing general ratchet screw or ratchet tool have been popular being extensive use of now, and it is quite convenient in the use, and torque value also can both reach the level that requires of industrial use along with the progress of science and technology.

Yet along with the change of consumer spending custom, even a lot of thing instrument is required that all different types and outward appearance will be arranged, same, the direction control structure of ratchet screw also is constantly to change and to develop, and just can meet the requirement of modern consumer now.

The current existing common ratchet screw or the direction control structure of ratchet tool, as No. 386476 " ratchet spanner structure-improved " (seeing annex one bulletin text for details) of Taiwan patent announcement, No. 422158 " the combined type reversing ratchet wrench structural improvement of high torsion " (seeing annex two bulletin texts for details) of Taiwan patent announcement, No. 382298 " switching construction that turns to of ratchet spanner is improved " (seeing annex three bulletin texts for details) of Taiwan patent announcement, No. 408653 " ratchet-driven tool (one) " (seeing annex four bulletin texts for details) of Taiwan patent announcement, Taiwan patent announcement No. 399510 " a kind of ratchet spanner switching button structure improvement " (seeing annex five bulletin texts for details).The content of above-mentioned each patent all is the different structure-improveds of relevant direction control structure, it serves to show that industry is all developing towards these direction research and development.

Above-mentioned is the direction control structure of general existing ratchet, though it can provide effect that user one has the reversing ratchet wrench structure, really has progressive, but when using, reality but finds also to have in its structure controlling party to defective inconvenient and that conflict is arranged in the use, requirement apart from the user still has certain distance, the direction control structure that causes this ratchet fails to reach best result of use in practical application.This shows that the direction control structure of above-mentioned existing ratchet is still demanded urgently further being improved.

In order further to improve the direction control structure of ratchet, relevant manufacturer there's no one who doesn't or isn't seeks the road that solves painstakingly, but does not see always that for a long time suitable design finished by development, and this obviously is the problem that the anxious desire of relevant dealer solves.

The applicant also is the leading industry of instrument circle, naturally also at the row of being devoted to make great efforts improvement, therefore because the problem that the direction control structure of above-mentioned existing ratchet exists, the design people is based on being engaged in this type of product design manufacturing abundant for many years practical experience and professional knowledge, actively studied innovation, in the hope of founding a kind of direction control structure of new and improved ratchet, can improve the direction control structure of general existing on the market conventional ratchet, make it have more practicality.Through constantly research, design, and after studying sample and improvement repeatedly, create the present invention who has practical value finally.

Summary of the invention

Main purpose of the present invention is, overcome the problem of the direction control structure existence of existing ratchet, and provide a kind of direction control structure () of new and improved ratchet, technical problem underlying to be solved is can improve the general existing controlling party of ratchet tool existence of commonly using to defective inconvenient and that conflict is arranged in the use, make its direction control structure comprise that a control is to a piece and an elastic component, this control is provided with a locating slot and two top supporting parts to piece, elastic component comprises that two push up pull an end and an axial region, with certain hyte part elastic component is positioned in the locating slot, the back side of brake block then is provided with two stopper portions and pushes up the end top of pulling for two of elastic component and pull, and it is firm fully to reach structure, controlling party is to very convenient, can not produce conflict in the use, and use effect very accurately, quite have industrial utilization.

Another object of the present invention is to, a kind of direction control structure of ratchet of improvement is provided, technical problem to be solved is to make its control structure convenient in assembling, more meet design concept, be suitable for practicality more, and can increase economic efficiency, thereby have the effect of enhancement on the whole, and have the value on the industry.
