Abstract

The utility model discloses a spanner which comprises tong arms and jaws, wherein the tong arms comprise two symmetrical long-strip structures and are connected through a hinge, the jaws are symmetrically formed in the side end surface of each tong arm from top to bottom sequentially and respectively, and each jaw adopts a half-hexagon shape. Multiple bolt models are integrated in the spanner, so that work can be conveniently and rapidly finished, the trouble for changing the spanner is omitted, and the spanner is multipurpose.

Description

Spanner

Technical field

The utility model relates to the instrument that can be used for loading and unloading hex bolts, relates in particular to the spanner that can load and unload various bolts.

Background technology

At present, people often will use the instrument of spanner when panel beating, while particularly running into bolt, be all generally to use double offset ring spanner, but each double offset ring spanner only have two wrench, are only applicable to two kinds of bolts, so use very inconvenient.Although monkey wrench is but arranged, can adapt to more bolt, only have two faces due to bolt stressed in stubborn, so be easy to make the bolt distortion, cause the bolt slippage, cause damage parts, so shortcoming is also clearly.

Summary of the invention

The utility model, in order to overcome the above problems, has proposed spanner, and it is difficult for skidding, and can tighten easily or looser a bolt, and can not make its distortion again.

Based on above purpose, the technical solution of the utility model is: spanner, comprise clamp handle and jaw, and described clamp handle is divided into two symmetrical length of a film strip structures and is connected through the hinge; Every clamp handle and be positioned on side end face, the symmetrical jaw that has respectively successively from top to bottom, described each jaw is half hex shape.

Also comprise two pairs of secondary spanners, described two pairs of subplate hands are connected through the hinge respectively in the bottom of each clamp handle.

The end face of described secondary spanner is the semicircular arc structure, is distributed with successively the semicircular arc groove on described clamp handle, and described secondary spanner is positioned at this groove.

The shape that two jaws piece together is the interior hexagon of crack mouthful.

Beneficial effect

1) integrated multiple bolt model above wrench, can work easily and fast, save with the trouble of changing spanner, one at most;

2) increase secondary spanner, can easierly use grasped, and increase moment.In addition, can the folded segment save space.

The accompanying drawing explanation

Fig. 1 is that the master of the utility model spanner looks schematic diagram;

Fig. 2 is the attached schematic diagram of looking of the utility model spanner;

Fig. 3 is that the spanner master that the secondary spanner of the utility model launches looks schematic diagram.

The specific embodiment

As shown in Figure 1 to Figure 3, spanner, comprise clamp handle and jaw, and described clamp handle is divided into two symmetrical length of a film strip structures and is connected through the hinge; Every clamp handle and be positioned on side end face, the symmetrical jaw that has respectively successively from top to bottom, described each jaw is half hex shape.Also comprise two pairs of secondary spanners, can increase conversely moment like this.Described two pairs of subplate hands are connected through the hinge respectively in the bottom of each clamp handle.The end face of described secondary spanner is the semicircular arc structure, is distributed with successively the semicircular arc groove on described clamp handle, and described secondary spanner is positioned at this groove.The shape that two jaws piece together is the interior hexagon of crack mouthful.In peaceful bolt, both sides are exactly to have six altogether, can tighten easily or looser a bolt so be difficult for skidding in the face of bolt strained with three faces simultaneously, can not make its distortion again.

Advantage of the present utility model is as follows:

1, integrated multiple bolt model above spanner, can work easily and fast, save with the trouble of changing spanner, one at most.

2, increase secondary spanner, can easierly use grasped, and increase moment.

3, secondary spanner can the folded segment save space.

Claims

1. spanner is characterized in that: comprise clamp handle and jaw, described clamp handle is divided into two symmetrical length of a film strip structures and is connected through the hinge; Every clamp handle and be positioned on side end face, the symmetrical jaw that has respectively successively from top to bottom, described each jaw is half hex shape.

2. spanner according to claim 1, it is characterized in that: also comprise two pairs of secondary spanners, described two pairs of subplate hands are connected through the hinge respectively in the bottom of each clamp handle.

3. spanner according to claim 2, it is characterized in that: the end face of described secondary spanner is the semicircular arc structure, is distributed with successively the semicircular arc groove on described clamp handle, and described secondary spanner is positioned at this groove.

4. spanner according to claim 1 is characterized in that: the shape that two jaws piece together is the interior hexagon of crack mouthful.
