Abstract
The invention discloses a demounting device which comprises a handle and a fork portion formed on the end portion of the handle. The fork portion has an upper surface and a lower surface, the lower surface is a smooth plane, the upper surface is nonplanar, and the demounting device is made of stainless steel. The upper surface of the lower surface is arranged to be nonplanar, so that when the fork portion is inserted in a gap between a turning screw and a connecting rod, contact friction force can be increased, and a demounting tool is enabled not to be easy to slide out. In addition, the demounting device is made of the stainless steel which has good resistance to oxidation and high hardness, thereby being less prone to being broken and worn during use, so that service life of the demounting tool is greatly improved.
Description
Technical field
The present invention relates to a kind of automobile-used extracting tool, relate in particular to a kind of extracting tool that is used for dismantling the suspention connecting rod.
Background technology
Traditional vehicle dismounting device, in order to from turning to screw of vehicle suspension system, connecting rod is pulled down, the fork that it comprises handle and is formed at the handle front end, this fork is wedge shape, can turn to the gap between screw and connected connecting rod for injecting, so as by connecting rod from turning to screw to pry open.
The fork of traditional provision for disengagement, its upper surface and lower surface are smooth surface, in the course of the work, due to the frictional force deficiency, and easily skid off, and it is very inconvenient to use.
In addition, the material of traditional extracting tool generally adopts iron and alloying metal, adopts iron to get rusty easily, and adopts general alloying metal, and its hardness also difficulty meets instructions for use, in use easy to wear.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, a kind of extracting tool be provided, solve in prior art extracting tool frictional force not enough, easily get rusty and problem easy to wear.
The technical solution adopted for the present invention to solve the technical problems is: a kind of provision for disengagement comprises:
Handle;
Be formed at the fork of described handle end, described fork has a upper surface and a lower surface, and described lower surface is smooth plane, and described upper surface is non-planar, and described provision for disengagement is made by stainless steel.
Preferably, in above-mentioned provision for disengagement, described upper surface is zigzag.
Preferably, in above-mentioned provision for disengagement, described upper surface is formed with the centrum of a plurality of projections.
Preferably, in above-mentioned provision for disengagement, the surface of described handle is formed with anti-skidding lines.
Preferably, in above-mentioned provision for disengagement, between described handle and fork, removably connect.
Preferably, in above-mentioned provision for disengagement, the end of described handle is formed with external screw thread, and described fork is formed with and coordinates described externally threaded screw.
Preferably, in above-mentioned provision for disengagement, described stainless material comprises by weight percentage: 0.25% carbon; 3.0% molybdenum; 2.8% copper; 12.8% chromium; 0.65% silicon; 0.03% neodymium; 0.04% sulphur; 0.01% phosphorus; 0.8% manganese; Surplus is iron.
Preferably, in above-mentioned provision for disengagement, in described stainless material, also include nickel.
Preferably, in above-mentioned provision for disengagement, the percentage by weight of described nickel is 0.5%.
Preferably, in above-mentioned provision for disengagement, described fork is wedge shape.
The invention has the beneficial effects as follows:
The upper surface of fork of the present invention is set to molded non-planar, such as: the centrums of zigzag, projection etc., when the fork insertion is turned to the gap between screw and connecting rod, can increase the frictional force of contact, and make extracting tool be difficult for skidding off.
In addition, provision for disengagement is made by stainless steel, and the stainless steel adopted has good oxidative resistance and good hardness, so not frangibility and wearing and tearing in use procedure, the service life of greatly improving extracting tool.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of provision for disengagement in the specific embodiment of the invention.
In figure:
The specific embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
Most preferred embodiment of the present invention as shown in Figure 1, the provision for disengagement in this enforcement, comprise handle 1, handle 1 has a handheld terminal 11, and the surface of handheld terminal 11 is provided with anti-skidding lines 111, and this anti-skidding lines is preferably the centrum of a plurality of projections, being easy to expect, can be also other lines such as corrugated.Handle 1 also has a link 12, and link 12 arranges screw 121.
Provision for disengagement also comprises a fork 2, and fork 2 is the shape of a hoof, and its working end is the wedge shape setting, to facilitate to insert, turns to the gap between screw and connected connecting rod.
The rear end of fork 2 is provided with the external screw thread 23 coordinated with screw 121, to realize removably connecting of fork 2 and handle 1.
Be easy to expect, external screw thread also can be arranged on handle, correspondingly, is equipped with screw on fork.
Fork 2 has upper surface 21 and lower surface 22, and wherein, lower surface 22 is level and smooth plane, and upper surface 21 is zigzag 211.By jagged upper surface, to increase the frictional force of extracting tool.
Be easy to expect, the upper surface 21 of fork 2 can be also the nonplanar structure of other shapes, such as protruding centrum etc.
In order to make the provision for disengagement in the present embodiment have good hardness and non-oxidizability, in the present embodiment, provision for disengagement is made by stainless steel material, and this stainless material comprises by weight percentage: 0.25% carbon; 3.0% molybdenum; 2.8% copper; 12.8% chromium; 0.65% silicon; 0.03% neodymium; 0.04% sulphur; 0.01% phosphorus; 0.8% manganese; Surplus is iron and inevitable impurity.
Can also contain 0.5% nickel in above-mentioned stainless steel, further to promote the rust-proof effect of extracting tool.
