Description

Adjustable spanners

Technical field

The invention belongs to hardware ＆ tools technical field, specifically, more particularly, to a kind of adjustable spanners.

Background technology

Spanner is a kind of conventional installation and extracting tool.Twist bolt, screw, nut and other spiral shells using lever principle Line tightly holds bolt or the opening of nut or the hand tools of trepanning firmware.Spanner is generally formed with clamping in the one or both ends of shank The opening of bolt or nut or set hole, during use, threadingly direction of rotation applies external force in shank, just can twist bolt or nut. At present, conventional spanner has open-end wrench, double offset ring spanner, adjustable wrench and monkey wrench.Open-end wrench and double offset ring spanner can only Realize the elastic of single specification firmware；Adjustable wrench, because of complex process, easily skids, and utility ratio is relatively low；Monkey wrench pair The surface breakdown of workpiece is more serious.

Because the specification of firmware is various, workman needs to carry the spanner of plurality of specifications species, there is presently no one kind Spanner is not in the case of destroying stud or nut it is adaptable to the firmware of plurality of specifications or special size.

Content of the invention

It is an object of the invention to overcoming drawbacks described above, provide a kind of adjustable spanners, its structure is simple, easy to use, Enable elastic to different specification size firmware, locking power is greatly it is not easy to skid, and protects workpiece injury-free.

Described adjustable spanners, including wrench body, described wrench body is provided with set hole and equally distributed groove, It is provided with the mobile fluted disc cooperating and ratchet, mobile fluted disc is provided with the deep-slotted chip breaker A with groove cooperation, groove in wrench body Inside it is provided with sliding shoe, sliding shoe passes through deep-slotted chip breaker A to be flexibly connected with mobile fluted disc by bearing pin, and described mobile fluted disc circumference is taken up an official post Anticipate the tangent line of any with cross this point deep-slotted chip breaker A excircle on tangent line angle a be 45 ° 60 °.

Further, described mobile fluted disc is additionally provided with the deep-slotted chip breaker B of concentric therewith, wrench body is passed through by bearing pin Deep-slotted chip breaker B is flexibly connected with mobile fluted disc.

Further, described ratchet is hinged with wrench body by bearing pin, is provided with elasticity dress between ratchet and wrench body Put.

Further, on the deep-slotted chip breaker A excircle of the tangent line of any point and this point of mistake on described mobile fluted disc circumference The angle a of tangent line is 55 °.

Further, the chemical component weight percentage of described mobile fluted disc and sliding shoe is C：0.45 0.6%, Si： 0.35%th, Mn：0.35 0.45%, Cu：0.2 0.4%, Ti：0.03 0.05%, Cr：0.08%th, Ni：0.13%th, RE： 0.02%, remaining is Fe.

Further, the chemical component weight percentage of described mobile fluted disc and sliding shoe is C：0.55%th, Si： 0.35%th, Mn：0.4%th, Cu：0.3%th, Ti：0.04%th, Cr：0.08%th, Ni：0.13%th, RE：0.02%, remaining is Fe.

Compared with prior art, the invention has the beneficial effects as follows：

1st, present configuration is simple, easy to use, is joined with the deep-slotted chip breaker A in mobile fluted disc by the groove in wrench body Close, the orientation realizing sliding shoe clamps and unclamps, so that the present invention is applied to the firmware of plurality of specifications and special size, carries Convenient, highly versatile；

2nd, ratchet and the tooth socket fit on mobile fluted disc carry out locking, and locking power is strong, safe and reliable；

3rd, mobile fluted disc carries out rotary spacing by the deep-slotted chip breaker B of concentric therewith it is achieved that moving effective shifting of fluted disc Dynamic, using more convenient；

4th, for ensureing hardness and the intensity of mobile fluted disc and sliding shoe, it is made using special substance, substantially prolongs The service life of the present invention.
