Abstract
A rapid opening-closing rotary spanner comprises a fixed spanner body and a clamp claw, the spanner is characterized in that the clamp claw is hinged with the fixed spanner body by hinge, a torsion spring is arranged between the fixed spanner body and the clamp claw, one end of the torsion spring is arranged fixedly on the fixed spanner body, the other end of the torsion spring is connected with the clamp claw. The benefit of the utility model is to screw the various model of nuts. When screwing nut, the clamp claw can tightly cling to the clamped object under the spring force,when required to repeat clamping, the spanner can rotate back, when rotating back, the nut will not become loose while the nut will be clamped tight once again, during screwing nut, the original line contact to the sharp angle of nut is changed into face contact, the nut will not be screwed bald and uneasy to be deformed, the utility model has simple process, wide application, and convenient operation.
Description
Technical field
The utility model belongs to the manually operated tools field, relates to a kind of spanner.
Background technology
Generally by fixedly pulling body and jaw is formed, the application of adjustable wrench is very general for existing adjustable wrench.But there are many drawbacks in existing adjustable wrench when turning nut: (1) when turning nut, stress point is easily twisted the wedge angle of nut bald on the nut wedge angle.(2) if the surrounding space of nut is very little, when turning, every rotation clamping again of once all will stopping turns again, has reduced operating efficiency.For addressing the above problem, the patent No. is that the Chinese utility model patent of ZL92105567 discloses a kind of " Wedge type spanner ", when utilizing this spanner to turn nut, two voussoirs can tightly cooperate with nut, when after turning once, needing to change clip position again, only the spanner revolution need be got final product, improve operating efficiency.But there are the following problems in making and using for this kind spanner: (1) is because the clamping face of jaw is arcwall face, when the front end face of two jaws contacts closure, leave the space between the rear end clamping face of two jaws, when turning the nut of minor diameter, this kind spanner is just powerless, has limited the range of application of spanner.(2) manufacturing process complexity.Because need bore two orthogonal holes of center line on jaw, and also need place voussoir, spring etc. in the hole, structure member is more, difficulty of processing is very big.
Summary of the invention
In order to overcome the deficiency that prior art exists, the utility model provides a kind of rapid folding revolution spanner, and this spanner does not need to change clip position again when turning nut, and manufacturing process is simple, and is applied widely.
The technical scheme that its technical problem that solves the utility model adopts is: design a kind of rapid folding revolution spanner, comprise and fixedly pull body and jaw, it is characterized in that jaw and fixedly pull body hinged by hinge, fixedly pull between body and the jaw torsion spring be set, an end of torsion spring be fixed on fixedly pull on the body, the other end and jaw link.
The utility model is offered dentate groove on the clamping face of fixedly pulling body, can increase chucking power.For adapting to the nut of different-diameter, the clamping face setting of jaw is step-like.
The beneficial effects of the utility model are:
(1) can be applicable to turn the nut of multiple model.When turning nut, jaw is clipped on the gripping object by the interaction energy subsides tightly of spring force and is unlikely to loosening; When needs clamping again, spanner revolution get final product, during the spanner revolution, neither can be with nut loosening, and the while clamps nut once more effectively; When turning nut, change over the face contact by original line contact to the nut wedge angle, can nut is stubborn bald, nut is not yielding.
(2) be provided with dentate groove owing to fixedly pull the clamping face of body, when turning gripping object, increased chucking power, can clamp bald nut and pipe spare, played the effect of pipe wrench.
(3) simple, the applied range, extremely easy to use of the utility model manufacturing process.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further elaborated.
Fig. 1 is the structural representation of an embodiment of the utility model;
Fig. 2 is another user mode schematic diagram embodiment illustrated in fig. 1;
Fig. 3 is the A-A schematic diagram of Fig. 1.
Among the figure, 1. hinge is 2. fixedly pulled body, 3. dentate groove, 4. nut, 5. jaw, 6. torsion spring.
The specific embodiment
As shown in Figure 1, jaw 5 is with fixedly to pull body 2 hinged by hinge 1, and jaw 5 can rotate around fixedly pulling body 2.Among Fig. 3, fixedly pull between body 2 and the jaw 5 torsion spring 6 be set, an end of torsion spring 6 be fixed on fixedly pull on the body 2, the other end and jaw 5 link.Fixedly pull on the clamping face of body 2 and offer dentate groove 3.The clamping face of jaw 5 is step-like.
When turning nut, nut 4 is placed between the clamping face of fixedly pulling body 2 and jaw 5, and jaw 5 is by the elastic force of torsion spring 6 and be pressed on the nut 4.When need changing clip position, body 2 is fixedly pulled in revolution, and jaw 5 rotates to an angle around fixedly pulling body 2, reset clip position after, continue to turn nut again, jaw tightly is pressed on the nut by torsion spring again.So constantly repeatedly and with nut screwing clamping.
For adaptation turns the nut of different-diameter, the clamping face setting of jaw 5 is step-like.So, the clamping face of jaw 5 and the width of fixedly pulling between body 2 clamping faces also gradually change, and have adapted to the requirement of different nut diameters.
Claims (3)
1. a rapid folding revolution spanner comprises and fixedly pulls body and jaw, and to pass through hinge hinged with fixedly pulling body to it is characterized in that jaw, fixedly pull between body and the jaw torsion spring be set, an end of torsion spring be fixed on fixedly pull on the body, the other end and jaw link.
2. rapid folding revolution spanner according to claim 1 is characterized in that fixedly pulling on the clamping face of body and offers dentate groove.
3. rapid folding revolution spanner according to claim 1 is characterized in that the clamping face of jaw is step-like.
