Abstract

The invention discloses a wrench which comprises wrench handles and jaws, wherein the wrench handles are divided into two symmetric strip-shaped structures and are connected through a hinge; jaws are sequentially and symmetrically formed in the side end faces of the wrench handles from the top down; and each jaw is semi-hexagonal. Various bolt types are integrated on the wrench, so that the wrench can work conveniently and quickly, a trouble of replacing the wrench is eliminated, and the wrench is multipurpose.

Description

Spanner

Technical field

The present invention relates to can be used for loading and unloading the instrument of hex bolts, relate in particular to the spanner that can load and unload various bolts.

Technical background

At present, people often will use the instrument of spanner when panel beating, when particularly running into bolt, generally all be 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, because bolt only has two faces stressed when twisting, 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 present invention has proposed spanner in order to overcome the above problems, 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, technical scheme of the present invention 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 the 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 crack mouthful interior hexagon.

Beneficial effect

1) integrated multiple bolt model above the wrench can be worked 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.

Description of drawings

Fig. 1 is that the master of spanner of the present invention looks schematic diagram;

Fig. 2 is the attached schematic diagram of looking of spanner of the present invention.

The specific embodiment

To shown in Figure 2, spanner comprises clamp handle and jaw such as Fig. 1, 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 the 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 crack mouthful interior hexagon.Both sides are exactly to have six altogether, can to tighten easily or looser a bolt so be difficult for skidding in the face of bolt strained with three faces simultaneously in peaceful bolt, can not make its distortion again.

Advantage of the present invention is as follows:

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

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

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 the 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.
