Description

Continuously turned multi-gear pipe wrench

The utility model relates to and a kind ofly has only two main parts but need not adjust spanner, the pipe wrench all-purpose instrument of continuously switching.

Now, the pipe wrench of national standard (GB8406-87) has five kinds of forms, all need clamp female the adjusting, not only bothersome but also switching work continuously, and the active pipe tongs wrench degree of regulation of novel eave tile is too little, use value is limited.

The purpose of this utility model will provide a kind of exactly and need not adjust and spanner, the pipe wrench dual tool of continuously switching, and two main parts are only arranged, and cost is extremely low.

The purpose of this utility model is achieved in that continuously turned multi-gear pipe wrench clamps handle by many grades of binding clips and high mountain and forms, the colluding the shape jaw and can form of many grades of binding clips by cambered surface, also can form by a plurality of angled planes warpage, the high mountain that the shelves offered from the side more than one mouthful is arranged on the turning arm of many grades of binding clips or have a grade hole, a high mountain pincers handle is provided with pin shaft hole, after binding clip being penetrated the cavity of high mountain centre, the use bearing pin is fixed, and binding clip can wide-angle rotate in cavity; The method of gear shift has two kinds, for the shelves mouth structure, need only mention binding clip, and it is broken away from from bearing pin, and the shelves that select to need then mouthful are hung bearing pin and get final product, for the shelves pore structure, then need to fix on the lock of high mountain is protruding with bearing pin with collar groove and collar; The pincers handle can connect together with regular jaw, also can be divided into two, slots on the pincers handle, in the regular jaw embedded groove, uses rivet to tighten together, and regular jaw can form cambered surface, also can be formed by a plurality of angled planes warpage; In the groove of high mountain cavity bottom, the supporting reed is housed, under the nature, because the effect of reed, the perk of turning arm rear end goes back to receipts under the hook-shaped jaw, is close to closure with regular jaw.

Though the utility model only has binding clip and two main parts of pincers handle, but owing to collude shape jaw and many grades of conversion, its jaw can reach state's dimensioning continuously and can surpass state's dimensioning to super large from zero, but because turning arm wide-angle rotation, depressing turning arm rear end jaw magnifies, unclamping the turning arm rear end in reed effect lower jaw closure, thereby switching work continuously, is the simplest and pipe wrench, spanner that best performance is different of structure in the world at present.

Concrete structure of the present utility model is provided by following examples and accompanying drawing thereof.

A kind of continuously turned multi-gear pipe wrench schematic diagram that Fig. 1 provides for the utility model.

Fig. 2 is for colluding shape jaw schematic diagram.

Fig. 3 is two kinds of different rotary arm configuration schematic diagrames.

Fig. 4 is the fixing schematic diagram of collar.

As shown in Figure 1, (1) for colluding the shape binding clip, (2) are high mountain pincers handle, and (3) are bearing pin, and (4) are rivet.Wherein (2.1) are high mountain, which is provided with pin shaft hole (2.2), and turning arm (1.2) uses bearing pin to fix, and can wide-angle rotate in cavity (2.3).Regular jaw (2.4) can connect together with the pincers handle, also can be divided into two, uses rivet to tighten together.

As shown in Figure 2, colluding shape jaw (1.1) can have various ways, and Fig. 2 (a) is formed by cambered surface, and Fig. 2 (b), Fig. 2 (c) are formed by a plurality of angled planes warpage, and Fig. 2 (d) is different with former three can not to establish teeth.

Shown in Fig. 3 (a), have the shelves mouthful (1.3) that can slip on the turning arm (1.2) with upper pin, also can shown in Fig. 3 (b), offer a grade hole (1.4).The gear shift of shelves mouth structure is very convenient, bearing pin is deviate from from the shelves mouth, the shelves that select to need again mouthful are hung bearing pin and are got final product, the bearing pin (5) that the gear shift of shelves pore structure then needs to collar groove (5.1) to be arranged inserts, re-use last pinning of the lock of collar (6) on high mountain protruding (2.5) and get final product, shown in Fig. 4 (a), Fig. 4 (b).

Many grades of rotatable wrench of company do not need to regulate, as long as one hang and promptly work fastenedly on the work package, are mentioning counterclockwise when clamping handle, because twisting force compressing reed, jaw is forced to magnify and forms less unyielding idle running, when pulling the pincers handle clockwise, kills workpiece and makes workpiece follow rotation because of teeth resistance jaw diminishes, form continuous switching, therefore claim the present invention to connect rotatablely, one hang can continuous switching, i.e. pipe fitting fastenedly, nut fastenedly again, diverse in function.Pincers are female to be adjusted owing to do not use, also needn't tooth punching on binding clip, and manufacturing is conformed to the principle of simplicity, and cost accounting reduces greatly, is the replacement elaboration of new century.

Claims (1)

1, a kind of continuously turned multi-gear pipe wrench is characterized in that being made up of many grades of binding clips and high mountain pincers handle:

(A) many grades of binding clips (1) colludes shape jaw (1.1) and can be formed by cambered surface, also can form by a plurality of angled planes warpage, the shelves of offering from the side more than one mouthful (1.3) are arranged on the turning arm (1.2) or have a grade hole (1.4), the high mountain (2.1) of high mountain pincers handles (2) is provided with pin shaft hole (2.2), after binding clip being penetrated the cavity (2.3) of high mountain centre, use bearing pin (3) fixing, binding clip can wide-angle rotate in cavity;

(B) method of gear shift has two kinds, for the shelves mouth structure, need only mention binding clip, it is broken away from from bearing pin, the shelves that select to need then mouthful are hung bearing pin and get final product, and for the shelves pore structure, the bearing pin (5) and the lock of collar (6) on high mountain protruding (2.5) that then need to have collar groove (5.1) are upward fixed;

(C) the pincers handle can connect together by same regular jaw (2.4), also can be divided into two, slots on the pincers handle, in the regular jaw embedded groove, use rivet (6) to tighten together, regular jaw can form cambered surface, also can be formed by a plurality of angled planes warpage;

(D) in the groove below the high mountain cavity, the supporting reed is housed, under the nature, because the effect of reed, the perk of turning arm rear end goes back to receipts under the hook-shaped jaw, is close to closure with regular jaw.
