Abstract
The utility model discloses a wrench which has the non-skid performance in the process of turning a nut. The non-skid wrench is characterized in that a multi-angle turning opening of a plum blossom wrench is changed into a hexagonal turning opening without an angle. The hexagonal turning opening without an angle is a hexagon whose corner angle parts are not closed. The side lines of the hexagon are selectively provided with fastening screws. The hexagonal turning opening without an angle can carry out turning various nuts with corresponding specifications. Besides, the non-skid wrench can carry out turning a nut whose sliding angle is rusted.
Description
The utility model relates to a kind of Wrench, a kind of spanner that in use has non-skid property.
Usually, double offset ring spanner, box spanner, adjustable wrench, fork spanner are main spanner class instruments.They pull the characteristics of turning round nut all is that the force concentrates on the top of the horn with the diagonal angle, angle, and this class spanner in use can produce a spot of sliding angle phenomenon, and reason is as follows: (1) the top of the horn to pull torsion point more shallow narrower; (2) some inexact Wrench; (3) use repeatedly of same nut; (4) the dead fiery nut of corrosion.The generation of sliding angle nut can cause unnecessary trouble and loss.
The purpose of this invention is to provide the anti-skidding spanner of a kind of energy, it not only in use has antiskid function, and can pull the nut that causes sliding angle and turn round.
The object of the present invention is achieved like this: based on double offset ring spanner, it is an acerous mouth of pulling of hexagon that double offset ring spanner polygonal pulled a mouthful transformation of the way, and this hexagon is acerous to be pulled mouth and come down to the hexagon that its angle position is not all sealed.The position of not sealing is by the outside parallel opening in former drift angle both sides (account on one side former sideline 1/4), extend through the top of the horn point rear enclosed.The hexagon that this drift angle does not seal is acerous to be pulled mouthful has two kinds, and the one, the acerous mouth of pulling of the open broad in angle position is beneficial to easy to usely, and a kind of is the acerous mouth of pulling that drift angle is open narrower, the sideline is provided with holding screw, to tackle sliding angle corrosion nut.This hexagon is acerous pulls that mouthful to pull the characteristics of turning round nut be that the force is on the both sides of the top of the horn with the acerous angle that is with.The anti-skidding of this spanner be the reasons are as follows:
1, pulls when turning round to the top of the horn generation frictional property pressure, difficult sliding angle.
2, the top of the horn is not produced frictional property pressure, also can as usually pull the nut at sliding angle and turn round.
3, pull mouthful sideline and the nut contact-making surface is longer, have necessarily to pull to turn round to slide safety coefficient.
4, the line of force of pulling when turning round is tightr than spanner commonly used.
5, have holding screw, that can avoid making is inaccurate.
Fig. 1, double offset ring spanner basic model.
Fig. 2, the anti-skidding spanner of the present invention.
Below in conjunction with accompanying drawing in detail operation instruction is described in detail:
Fig. 1, double offset ring spanner (box spanner is also basic identical) have to be pulled mouthful 1, trigger piece 2, pulls and mouthful have 12 angles, is a polygonal mouth of pulling.
Fig. 2, anti-skidding spanner have acerous mouth 1, trigger piece 2, the holding screw 3 pulled of hexagon.An end of pulling mouth uses the acerous mouth of pulling of the open broad in angle position, and other end use is provided with acerous pull mouthful (the same specification in two ends) of holding screw.During use,, just can normally pull and turn round as long as,, rotate trigger piece 2 then with the acerous angle that is with the acerous mouthful corresponding specifications of nuts of 1 aligning of pulling.When running into sliding angle corrosion nut, then use the acerous mouth of pulling that is provided with holding screw 3, earlier with the acerous mouthful corresponding specifications of nuts of 1 cover of pulling, enable then holding screw 3 fixing after, just can rotate trigger piece 2 easily and pull and turn round.
Claims (1)
- A kind of anti-skidding spanner, by the acerous mouth 1 of pulling of hexagon, trigger piece 2, holding screw 3 constitutes, it is characterized in that the polygonal mouth 1 of pulling of double offset ring spanner is changed system into an acerous mouth 1 of pulling of hexagon, this hexagon is acerous, and to pull mouthful 1 be a hexagon that its angle position is not all sealed, the position of not sealing is by the outside parallel opening in former drift angle both sides (account on one side former sideline 1/4), extend through the top of the horn point rear enclosed, the hexagon that this drift angle does not seal is acerous pulls mouth two kinds: the one, and the acerous mouth of pulling of the open broad in angle position, the 2nd, the angle position is open narrower, sets up the acerous mouth of pulling of holding screw on the sideline.
