Abstract
The invention discloses a friction type manual wrench. The manual wrench comprises a base, a rectangular steel sleeve is arranged on the base, a steel sliding plate is in sliding fit in the rectangular steel sleeve, a jaw front end and a jaw rear end which are corresponding are fixed at the same ends of the steel sliding sleeve and the base respectively and are perpendicular to the steel sliding plate and the base respectively, a pressing plate is hinged to the rear end of the steel sliding plate, and matched wavy upper protrusions and lower protrusions are arranged on the inner walls of the pressing plate and the inner wall of the rear portion of the base. According to the friction type manual wrench, the steel sliding plate is pushed or retracted according to the size of a nut to be rotated, the pressing plate is put down to enable the lower protrusions to contact with the upper protrusions, the rear end of the wrench is held with a hand, and accordingly, an object to be rotated can be fastened or loosened, and rotation requirements of various nuts are met.
Description
Technical field
The present invention relates to mechanical wrench, specifically belong to friction-type manual wrench.
Background technology
1), the phenomenon that spanner and nut slide mutually appears in spanner when rotary nut the mechanical wrench of prior art, exists following shortcoming:.2), traditional spanner can only rotating diameter the nut that is certain fixed range.3) distance that, needs loaded down with trivial details operation just can reach jaw is consistent with the diameter of the object that will rotate.
Summary of the invention
The object of this invention is to provide a kind of friction-type manual wrench, according to the size of the nut that will rotate, promote or retraction steel slide plate, then putting down pressing plate contacts with projection by lower convexity, with the rear end of holding spanner, just the object that will rotate can be screwed or unclamps, meet the rotation requirement of various nuts.
Technical scheme of the present invention is as follows:
Friction-type manual wrench, include base, base is provided with rectangle steel bushing, in rectangle steel bushing, be sliding combined with steel slide plate, steel slide plate is fixed with respectively mutual corresponding jaw front end, jaw rear end with same one end of base, jaw front end, jaw rear end respectively with steel slide plate, the perpendicular setting of base, steel skateboard back-end is hinged with pressing plate, on the inwall at pressing plate and base rear portion, has respectively mutual wavy projection, the lower convexity mating.
The front end of described pressing plate is provided with pressing plate termination, and the rear end that is arranged at steel slide plate is rotated in pressing plate termination by rotating shaft.
The width of described pressing plate termination is less than pressing plate.
With prior art, beneficial effect of the present invention is as follows:
1, owing to having respectively lower convexity and projection on pressing plate and base, when contacting with projection, lower convexity has very large frictional resistance, can keep the stable distance between them by adjusting jaw front end and jaw rear end like this, overcome traditional spanner and when rotary nut, occurred the phenomenon that spanner and nut slide mutually.
2, pressing plate and steel slide plate link together by rotating shaft, touch steel slide plate and just can arbitrarily control the distance between jaw front end and jaw rear end after pressing plate is raised, and having overcome traditional spanner can only rotating diameter be the nut of certain fixed range.
3,, due to as long as promote or retract steel slide plate just to control the distance between jaw front end and jaw rear end, overcome the distance that the loaded down with trivial details operation of traditional needs just can reach jaw and be consistent with the diameter of the object that will rotate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
Referring to accompanying drawing, friction-type manual wrench, include base 1, base 1 is provided with rectangle steel bushing 2, in rectangle steel bushing 2, be sliding combined with steel slide plate 3, steel slide plate 3 is fixed with respectively mutual corresponding jaw front end 4 with same one end of base 1, jaw rear end 5, jaw front end 4, jaw rear end 5 respectively with steel slide plate 3, the perpendicular setting of base 1, steel slide plate 3 rear ends are hinged with pressing plate 6, on the inwall at pressing plate 6 and base 1 rear portion, there is respectively mutual wavy projection 7 of mating, lower convexity 8, the front end of pressing plate 6 is provided with pressing plate termination 9, the rear end that is arranged at steel slide plate is rotated in pressing plate termination 9 by rotating shaft, the width of pressing plate termination is less than pressing plate.
Claims (3)
1. friction-type manual wrench, include base, base is provided with rectangle steel bushing, it is characterized in that: in rectangle steel bushing, be sliding combined with steel slide plate, steel slide plate is fixed with respectively mutual corresponding jaw front end, jaw rear end with same one end of base, jaw front end, jaw rear end respectively with steel slide plate, the perpendicular setting of base, steel skateboard back-end is hinged with pressing plate, on the inwall at pressing plate and base rear portion, has respectively mutual wavy projection, the lower convexity mating.
2. friction-type manual wrench according to claim 1, is characterized in that: the front end of described pressing plate is provided with pressing plate termination, and the rear end that is arranged at steel slide plate is rotated in pressing plate termination by rotating shaft.
