Abstract

The invention relates to a spanner which comprises a handle and a spanner jaw, wherein one side face of the spanner jaw is provided with a threaded hole, a screw is assembled in the threaded hole, and the outer side of the screw is provided with a mechanism which enables the screw to be screwed. When in use, if a nut is worn, the screw is screwed into the threaded hole to abut against the nut, thereby ensuring the surface contact of the nut; and even if the hexagonal edges are worn, the nut can be demounted normally. The functions of the spanner can be realized by using a common tool, and thus, the structure is simple and the manufacture is easy.

Description

Spanner
Technical field
The present invention relates to a kind of spanner.
Background technology
Existing spanner, the opening size of spanner are greater than the nut size could guarantee that spanner can entangle nut, nutting again.There is a clearance C (Fig. 1) between nut and the spanner, existence just because of this gap, it when making the open-end wrench nutting the complete and spanner side applying in nut side, but the sideline of the turret head of nut and spanner contacts side surfaces (Fig. 2), so just cause the wearing and tearing of nut hexagonal sideline easily,, skidding can occur if it is excessive to wear and tear, the nut rotation be can't make, thereby the decomposition and the assembling of nut influenced.
Summary of the invention
The purpose of this invention is to provide a kind of spanner, can eliminate the device in gap between spanner and the nut, the line contact condition when changing spanner rotation nut is avoided wearing and tearing.
Technical scheme of the present invention is; Spanner comprises handle and pulls mouth that a described side of pulling mouth is provided with screwed hole, is equipped with screw in the screwed hole.The outside of described screw is provided with the mechanism that can make its precession, and described precession structure is a groove.
The present invention is provided with screwed hole by a side of pulling mouth, is equipped with screw in the screwed hole, in use, if wearing and tearing have appearred in nut, is screwed into screw by screwed hole, holds out against nut.The one side of nut hex surface is held out against by screw, and another side and spanner side are close to, and during rotating spanner, has just guaranteed that nut is the face contact like this, rather than the line contact, can not wear and tear in the hexagonal sideline.Even having worn and torn, the hexagonal sideline also can guarantee normally to dismantle nut.Simultaneously, be provided with the precession structure of screw in the outside of screw, can be easy to be screwed into screw, described precession structure is a groove, can use instrument commonly used just can realize its function, and is simple in structure, is easy to make.
Structure of the present invention is not limited to described common wrench, also comprises passing through moment loading and being easy to generate the spanner of wearing and tearing of other form, as casing tongs or the like.
Description of drawings
Fig. 1 is a gap schematic diagram between common wrench and the nut;
Fig. 2 is the schematic diagram of common wrench nutting;
Fig. 3 is a structural representation of the present invention;
Fig. 4 is the schematic diagram of nutting of the present invention.
The specific embodiment
As shown in the figure, spanner comprises handle and pulls mouth 1, it is characterized in that, a described side of pulling mouth 1 is provided with screwed hole, is equipped with screw 2 in the screwed hole; The outside of described screw 2 is provided with the mechanism that can make its precession; Described precession structure is a groove.

Claims (3)
