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, relate to particularly that a kind of its structure is firm, controlling party is to direction control structure (three) convenient, that use the ratchet that precisely, more is suitable for practical improvement.

The direction control structure (three) of the ratchet of the present invention's improvement, it mainly comprises a wrench body, ratchet-gear wheel, brake block and a direction control structure, this direction control structure and comprise that a control is to piece and the two elastic top device of pulling wherein, pull device and comprise a steel ball, spring and a headgear of this elastic top, this control is provided with two containing holes to piece, and this two containing hole is for the elastic top ccontaining usefulness of device of pulling, promptly this containing hole can supply above-mentioned headgear, spring and steel ball to receive into, and its steel ball can be pushed up pull about the top pull in the hole slot; The back side of brake block then forms and is provided with a stopper recess, and can be for pulled by elastic top usefulness that the headgear top of device pulls, so by said structure, can form the direction control structure with practicality of another different structure, be one have that structure is fully firm, controlling party to very convenient, can not produce conflict in the use, and use very accurate, more be suitable for practical ratchet tool direction control structure, and become a kind of new design that quite has practicality and progressive, be 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 inventor 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 defective of the direction control structure existence of existing ratchet, and provide a kind of direction control structure (three) of ratchet of improvement, technical problem underlying to be solved is to make it can improve general existing control of commonly using the ratchet tool existence has conflict in inconvenient or use drawback, and provide that a kind of structure is fully firm, controlling party to very convenient, can not produce conflict in the use, and use very accurate, more be suitable for practical ratchet tool direction control structure, and 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 control structure convenient in assembling, structural design is more reasonable, meet user demand more, and can increase economic efficiency, thereby have the effect of enhancement on the whole, and have the value on the industry.
