Abstract

The utility model provides a wrench. A jaw is composed of an arc-shaped surface and two surfaces on the inner side of an adjustable tong hook (2), the arc-shaped surface is arranged on the upper end of the handle (1), and an included angle of the two surfaces is 45 DEG to 75 DEG. The arc-shaped surface is crossed with one of the two surfaces. A spring (5) which causes the jaw to close is arranged between the adjustable tong hook and the handle. The using place of the wrench arranged in the utility model is enlarged, and the wrench arranged in the utility model overcomes the defects that original like wrenches have requirements on large working positions, etc.

Description

Spanner

The utility model relates to a kind of spanner.

ZL93244943.3 has introduced a kind of spanner, is made of handle and active pincers hook, and there is arcwall face the handle upper end, and there are four faces pincers hook inboard surely by certain angle.Though this spanner has suitable many, the advantage of simple structure of nut kind, and five faces are arranged in its jaw, and is too much to the containing of nut.When work, require to leave more operating position around the nut, can not equally with monkey spanner when some is barrier by the nut, still can use.When the nut axis was parallel to the ground, when especially requiring active pincers hook downward, must have a hand rest firmly to clamp hook could work in addition, as long as can not equally with adjustable wrench there be a hand just can work.Above-mentioned deficiency has limited the scope of application of workplace.

The purpose of this utility model is to remedy above-mentioned deficiency, provide a kind of can the big spanner of the scope of application of the same workplace with adjustable wrench.

Spanner provided by the utility model is made of handle (1) and active pincers hook (2), and it is two faces of 45 °～75 ° that the handle upper end has arcwall face, active pincers hook inboard that angle is arranged, and the arcwall face on one of them face and the handle intersects.The jaw of spanner promptly is made of two faces of active pincers hook inboard and the arcwall face on the handle.

The spanner of this structure because its containing to nut is few, still has two limits to stay outside the jaw for hex nut, and the operating position of spanner is little, endure when some obstacle of nut side.Also can make pipe vice uses.

Accompanying drawing is the utility model embodiment working state schematic representation.

1-handle among the figure, the active pincers hook of 2-, 3-obstacle, 4-nut, 5-spring

As shown in drawings:

Spanner provided by the utility model, handle (1) is hinged mutually with active pincers hook (2).The handle upper end is opened a side at jaw an arcwall face, and its arc wheel profile is that each dependence point (or line segment) when being suitable for certain specification scope nut is linked to be.Pincers hook inboard have two shapes at 45～face of 75 ° of angles, have transition face to connect on the position between two faces when being suitable for the minimum gauge nut.On these two faces and the arcwall face anti-slop serrations is arranged all.One spring (5) that mao jaw is closed up is arranged between handle and active jaw.Energy is binding nut automatically, to improve work efficiency.

Claims (2)

1. spanner, constitute by handle and active pincers hook, there is arcwall face the handle upper end, it is characterized in that there are two faces of 45 °～75 ° of angles this active pincers hook (2) inboard, arcwall face on one of them face and the handle on (1) intersects, and its jaw is made of arcwall face on two faces of active pincers hook inboard and the handle.

2. spanner as claimed in claim 1 is characterized in that having between active pincers hook (2) and the handle spring (5) that jaw is closed up.
