Description
Technical field
The utility model relates to a kind of ratchet wrench.
Background technology
Ratchet wrench is a kind of hand-operated tools of controlling the idle running direction, because it can allow the operator under the state that does not take off spanner, the rotating screw that does not stop, bolt or nut, not only make things convenient for user's operation, also overcome simultaneously the restriction on the segment space, so ratchet wrench is to use at present very extensively and important hand-held tool.
Existing sleeve, the overwhelming majority is an end hexagon groove, and an end square groove is by a square tenon transmission.This sleeve is in differing heights because transmission body and passive muscle power amount are transmitted in use, so sleeve is subjected to the shearing force effect, small dimension is difficult to transmitting large torque.
In addition, the meeting of existing sleeve exterior contour size is different because specification is different, at design and development, in storage and the transportation, is difficult to carry out standardization.
In addition, existing ratchet spanner is to be one horizontal fixed because of its driving head and handle, and the folding that can't break, thus when operating, narrower or other barrier is arranged as if the operating space, and make the driving head of spanner can't stretch into use, bring many inconvenience to the user.
The utility model content
The purpose of this utility model is to solve the problems of the prior art, and the ratchet wrench of a kind of fit easily and fast or taking-up carrier is provided.
The technical solution of the utility model is: a kind of ratchet wrench comprises wrench body and carrier; Described wrench body comprises handle and is arranged on the ratchet wheel pulling head of handle one end, be provided with the containing cavity that is regular polygon in this ratchet wheel pulling head, but described containing cavity inwall middle position is provided with the fixedly projection of carrier of blocking, and described carrier outer peripheral face middle position is provided with the end difference that matches with described projection.
Described containing cavity inwall middle part has a groove, is embedded with a C shape jump ring in this groove and forms described projection, and the inside diameter of this jump ring is less than the external diameter of a circle of described containing cavity.
Described carrier is a sleeve, and described sleeve outside is regular polygon, is complementary with described containing cavity, and the middle part, exterior angle of described sleeve is provided with described end difference; Described sleeve inner offers the jack that is regular polygon.
Described carrier is the sleeve conversion head, and this sleeve conversion head comprises that one is the solid body of regular polygon, and this solid body and described containing cavity are complementary; Described solid body upper and lower end has the plug that can link to each other with sleeve, convex with the hoodle that is used to tighten the sleeve ends in the insertion plug on the described plug sidewalls, the middle part of inwardly offering chamfering and solid body exterior angle in the top and/or the bottom at place, solid body exterior angle forms described end difference.
Also convex with some hoodles on the described containing cavity inwall.
The beneficial effects of the utility model are: utilize the projection be arranged on the ratchet wheel pulling head captured cavity wall that carrier (sleeve or connect sleeved sleeve conversion head) is imposed radially chucking power, and carrier outside middle position is provided with end difference, make things convenient for the depth location of carrier in containing cavity, so blocking good fixing effect between carrier and the ratchet wheel pulling head, easy to loading and unloading, and jump ring is a rigid body, and member firmly and not can frequently produce fatigue with using; The utility model also can be adjusted angle between ratchet wheel pulling head and the handle according to actual conditions in addition, and is practical more.
