Description

Emergent portable multi-functional shifting spanner

Technical Field

The utility model relates to a spanner especially relates to an emergent portable multi-functional shifting spanner.

Background

The wrench is a common mounting and dismounting tool in life, is an opening hand tool for screwing bolts and nuts by utilizing the lever principle, and usually, a clamping handle part is arranged at one end or two ends of a handle part and the handle part applying external force can screw the bolts or the nuts by applying the external force. The types of wrenches are various and can be divided into a double-ended wrench, a dual-purpose wrench, a shifting wrench, and the like. Ordinary spanner can only be applicable to the nut of a model, needs the different spanners of change size that do not stop when using, moreover, many different spanners of size carry inconveniently, occupy a large amount of spaces, cause the waste. The size of the wrench opening can be adjusted by the shifting wrench in a thread rolling mode so as to screw nuts of different types. However, the conventional shifting wrench is often too smooth to cause the phenomenon of twisting and slipping; moreover, the plane opening is only limited to plane clamping operation, and non-parallel plane parts and tubular objects cannot be screwed at all, so that the application range is limited.

Disclosure of Invention

In order to solve the problem, the utility model provides a many, the wide portable multi-functional shifting spanner of emergent of application scope of function, the device can adjust the opening size, adapts to the nut of different models, bolt, also can use with the screwdriver bit cooperation simultaneously for twist and change cross and a word screw.

The utility model provides a technical scheme that its technical problem adopted is: the wrench head adopts a three-jaw chuck structure, the contact position of the tail end of the movable clamping jaw 2 and the nut is provided with a clamp tooth, the nut is tightly clamped from three directions, the nut is prevented from sliding when being screwed, and meanwhile, the three-jaw structure is also beneficial to clamping non-planar structures such as pipes. The four-corner square hole movable clamping jaw 2 on the chuck body 1 is rotated through the chuck wrench 8 so as to adjust the size of the opening and adapt to nuts of different models. Spanner handle 3 has certain radian, and 3 planes of handle have certain distances from work plane, more make things convenient for the staff to twist and change, and application scope is wider, is equipped with insulating antiskid cover on the spanner handle 3, increases the comfort level when holding. There is plastic clamping groove 4 on the handle for place chuck wrench 8 and cross 6, a 7 screwdriver bits of word, have magnetic cross, a word screwdriver bit one end is the four corners square hole, it is the same with the 10 sizes in four corners square hole on the chuck body 1, be convenient for with the cooperation of chuck wrench 8, horizontal pole 5 above the chuck wrench 8 can be dismantled and the side surface has anti-skidding screw thread 9, it is more comfortable when using as the screwdriver handle, but screwdriver bit quick replacement.

The beneficial effects of the utility model reside in that: make the shifting spanner form better pincers and hold the effect through the three-jaw centre gripping that is equipped with the pincers tooth, thereby the pincers that have increased the pincers tooth terminal surface hold the power, the phenomenon of skidding is changeed in the wrong commentaries on classics that causes to the movable clamp plate positioning accuracy difference of having solved traditional shifting spanner, can form fine pincers to non-parallel face part and tubulose class object simultaneously and hold the effect, thereby multi-functional application has been expanded, its application scope has been enlarged, the size of keeping silent through the adjustment can adapt to the nut of different specifications, still be furnished with screwdriver bit simultaneously, can do the screwdriver use when satisfying the spanner function, convenient quick fastening and the dismantlement of carrying out the screw, just the utility model discloses light, conveniently carry, but wide application in outdoor emergent maintenance field.
