Abstract

The utility model relates to an open jaw type fast rotating universal spanner structure. Both side ends of the spanner body are respectively provided with a fork-shaped vice jaw, one selected side of which is provided with a plurality of consecutive thorn-shaped convex teeth, and the other side which faces the vice jaw is a smooth side. Accordingly, the utility model can be screwed quickly, and the utility model is suitable for clamping nuts with different sizes.

Description

Open type is changeed universal spanner soon

The relevant a kind of open type of the utility model is changeed the universal spanner structure soon, this spanner is constituted the jaw of its fork-shaped with a double wedge limit and a level and smooth limit that links up sour jujube shape, be to make when pulling spin nut, the mode of pulling that adopts point and face is with the turn nut, and is common to the turn operation of each size nut.

General being seen back-up wrench, its nut for a fixed dimension uses, carry out sealed to the nut of plurality of differently-sized or revolve when moving back as desire, then must possess the spanner of various different sizes for use, be the especially inconvenience that seems, therefore, it is at locating of its undersize of spanner and improvement to some extent, it still has some problems to produce on implementing, it mainly establishes the folder mouth of a fork-shaped in the side of wrench body, and be provided with some coherent folder teeth in the dual-side of folder mouth, and the mode of its turn screw of the spanner of so doing, the folder tooth that utilizes the Jia Kou both sides to be provided with fastens the place, two diagonal angles of screw and imposes that to pull rotation moving, so, the corner of nut is damaged because of stressed concentrated face, and then produce the phenomenon of skidding when moving in pulling rotation, make nut can't produce sealed or revolve the effect of moving back, and it is after whenever pulling once, being must mention once more to be desired the nut corner of clamping down on to align, is very not find a great convenience in the use.

Main purpose of the present utility model is to provide a kind of open type to change universal spanner soon, it respectively is provided with the jaw of different prong sizes with its both sides of pulling body, and each jaw has a double wedge limit and a level and smooth limit that links up sour jujube shape, utilize this sour jujube shape double wedge and level and smooth limit to clamp down on a corner and a flat limit of nut, can make this nut produce sealed or revolve the effect of moving back, and revolve when pulling body with oppositely pulling, can make the sour jujube shape double wedge of effect obtain quick transposition with direction.

The new purpose of this practicality is achieved in that a kind of open type changes universal spanner soon, comprise wrench body and jaw, the two side ends of wrench body is respectively established the jaw of a fork-shaped, then is provided with some coherent sour jujube shape double wedges on the selected limit of this jaw, and face then is a level and smooth limit in the another side of jaw.

The jaw size at its two ends of described wrench body is small one and large one shape.

The size of described sour jujube shape double wedge is equal.

Because adopt such scheme: transposition is pulled and is revolved fast, and also the nut of applicable different size is clamped down on.

Following conjunction with figs. describes feature of the present utility model and advantage in detail:

Figure 1 shows that stereo appearance figure of the present utility model.

Figure 2 shows that use floor map of the present utility model.

Figure 3 shows that user mode action schematic diagram of the present utility model.

Figure 4 shows that the action schematic diagram that the utility model resets fast.

As shown in Figures 1 and 2, the open type that the utility model is done is changeed the universal spanner structural design soon, mainly make the two side ends of wrench body 1 respectively establish the jaw 2 of a fork-shaped, on a selected limit of each jaw 2, then be provided with some coherent sour jujube shape double wedges 21, another side in jaw 2 then is a level and smooth limit 22, and jaw 2 sizes at wrench body 1 its two ends are small one and large one shape, clamp down on use with the nut 3 that different size is provided.

Change universal spanner soon when operating as above-mentioned open type, as shown in Figure 3, it utilizes this sour jujube shape double wedge 21 and level and smooth limit 22, face makes the jaw 2 of spanner can clamp down on apace on arbitrary corner of nut 3 and arbitrary flat limit and pull revolving, so that this nut 3 produces sealed or revolves the effect of moving back, and the mode of pulling that the utility model adopted is with point and the cooperation of face and turn nut 3, so can make nut 3 even stressed and do not have misgivings of damage nut 3 corners.

Moreover, as shown in Figure 4, if oppositely pull when revolving wrench body 1 with action direction, sour jujube shape double wedge 2, be that its hypotenuse emaciated face is from the state of clip in nut 3 corners, when wrench body 1 continues to pull when being threaded to an angle faces and circling round, then can make sour jujube shape double wedge 2, when cooperating level and smooth limit 22 to be held in the flat limit of nut 3 one, face once again clip on another corner of nut 3, but with make wrench body 1 its clip and pull and revolve nut 3, so pull and revolve so that jaw 2 can obtain transposition fast.

Again, the utility model do " open type is changeed universal spanner soon ", set small one and large one the jaw 2 in its two ends, being specially adapted to various big and small nuts 3 pulls and revolves, so, when in operation is carried out, running into the nut 3 that various sizes differ, only rely on both sides of the present utility model size jaw 2, can finish the handling operation of various sizes nut 3 smoothly, and must not change spanner again and again, to reach operation purpose rapidly, no matter make in factory or family, all need only have the utility model " open type is changeed universal spanner soon " and get final product, and must be the not in addition spanners of buying various single sizes, with the expenditure of paring down expenses. not more

Claims
