Description

A kind of better ratchet spanner of stability
Technical field
The utility model belongs to machine tool technical field, is related to a kind of spanner, in particular to a kind of stability is better Ratchet spanner.
Background technique
Spanner is common hardware tool in production activity, has the function of tightening or loose nut, but in life having Its thread turns of a little nuts is more, tightens a nut and needs to rotate many circles, common monkey wrench, double offset ring spanner are using When need to remove spanner from bolt or nut, then the suitable angle repetitive operation of reselection, such to pull not only Process is complicated, inefficiency, and the revolution that may cause bolt perhaps nut makes elasticity bolt or nut very not side Just.Ratchet spanner relative to common wrench at it using upper, have very strong advantage, in rotating nuts without removing lower ejector lever, only Need rotary spanner that the rotation of nut of lower a distance can be realized, can control spanner only make it is unidirectional movement without It causes to turn round.The connection structure of its internal support tooth of conventional ratchet spanner and ratchet is direct cooperation again by commutation dress at present Adjusting is set, such as a kind of combined anti-skid ratchet spanner that Patent No. 201620729403.4 is announced, the inside on head is Circular cavity structure and it is provided with ratchet, the support tooth matched with ratchet is provided between head and ratchet, it is known that support tooth is straight Connect and be arranged in Wrench head, therefore support tooth and be easy to appear latch in commutation process, and when in use between too long back brace Tooth is easy displacement, affects the stability and service life of spanner.
Summary of the invention
The purpose of this utility model be for the above-mentioned problems in the prior art, provide a kind of stability it is more preferable and The ratchet spanner of spanner service life can effectively be extended.
The purpose of this utility model can be realized by the following technical scheme: a kind of better ratchet spanner of stability, packet Shank body and the head for being set to shank body one end are included, the inside on the head is cylindrical empty cavity configuration and is disposed with positioning Axis, ratchet wheel block, baffle and snap ring, the locating shaft is vertically arranged at head center, and ratchet wheel block clearance fit is set to and determines It is rotated on the axis of position by center axis of locating shaft, the baffle passes through ratchet wheel block and ratchet wheel block and locating shaft are fixed on head Interior, baffle is connected by snap ring and head, which is characterized in that the reversing machine matched with ratchet wheel block is provided in the head Structure, the reversing mechanism include that support tooth, reversing key, reversing pin and swing link, the reversing pin are set to reversing key by spring Upper and reversing pin end is resisted against support tooth, is located at below reversing pin on the reversing key and offers card slot, the moon The arc groove matched with card slot is offered on dental lamina and is arranged in card slot, and the bottom surface of the support tooth is identical as crescent moon plate shape And it is resisted against on swing link.
The advantages of this ratchet spanner are as follows: list of the ratchet wheel block centered on locating shaft is realized by the cooperation of support tooth and ratchet wheel block To rotation, and its support tooth lower section of traditional ratchet spanner does not have support device, therefore the easy latch stability that shifts of support tooth is poor, Swing link is arranged by opening up card slot on reversing key in the utility model in card slot, allow the bottom surface of ratchet wheel block against In on swing link, supporting role is realized to ratchet wheel block by swing link, ratchet wheel block displacement can be effectively prevented, further, by Cooperated between swing link and reversing key by arc groove, therefore when reversing key rotation turns to support tooth, it can't band Dynamic swing link rotation, prevents swing link from keeping ratchet wheel block stuck.
In a kind of above-mentioned better ratchet spanner of stability, set between the head bottom surface and the contact surface of ratchet wheel block It is equipped with gasket.The design can reduce the frictional force between ratchet wheel block and head, increase the ride comfort of ratchet wheel block rotation.
In a kind of above-mentioned better ratchet spanner of stability, the end of the reversing key raises upward to form positioning Pin.Head lower end face has the circular groove matched with locating pin structure, rotates reversing key by the cooperation of positioning pin and circular groove After can tentatively fix, prevent reversing key from turning round in ratchet spanner use.
In a kind of above-mentioned better ratchet spanner of stability, spring is arranged on the locating shaft.Pass through spring Will not fall off ratchet wheel block sleeve in installation sleeve with steel ball cooperation in ratchet wheel block.
Compared with prior art, this ratchet spanner makes to support tooth and be not easy to shift have stability more preferable by the design of swing link The advantages of, and the service life of ratchet spanner can be increased.
