Spanner with anti-skid structure

Abstract

The invention discloses a spanner with anti-slip structure, which contains handle, wherein the handle surface possesses two gripping surfaces, which adjacent laterals of two gripping surfaces; the end of handle possesses driving head to span screw; the anti-slip part with irregular line is set on the handle surface, which provides non-directional friction on the thumb and fore-finger to obtain stable gripping force without stripping.

Description

Technical field [0001] The invention relates to a wrench with an anti-skid structure, in particular to a wrench with an anti-skid structure directly arranged on a handle. Background technique [0002] Wrenches are a necessity for people’s livelihood in the field of hand tools. Taiwan’s hand tool industry is already the world’s leader in the production of wrenches. There are many types of wrenches, and there are hundreds of related patent cases. It is a narrow field in the industry, so innovation and reform are more driven by small changes. It is a route that is not easy to expand. However, small improvements still contribute to users, which is a commendable thing. [0003] Refer to the case of a ratchet wrench with a non-slip grip sheath of Taiwan Patent Certificate No. M240308, which mainly includes a wrench body 10 and a non-slip grip sheath 20. The middle section of the wrench body 10 is recessed with a handle 11, and the non-slip handle sheath 20 is integrally formed on the h...

Problems solved by technology

However, the anti-slip handle sheath 20 is not covered on the neck of the wrench body 10, and the neck of the wrench body 10 is still smooth, so it cannot provide anti-slip function, so it is easy for the operator's hand to slip out of the wrench body 10. Disadvantages of injury caused by hitting the hand with a foreign object

[0007] In addition, even when the non-slip grip sheath 20 is completely covered on the neck of the wrench body 10, there are still disadvantages. Because the material of the non-slip grip sheath 20 made of rubber or plastic is relatively soft, it is easy to contact with the metal. After the tools made by the system collide with each other, they will be scratched and damaged, resulting in the shortcoming that the anti-skid effect is gradually reduced

And after the colloidal anti-slip handle sheath 20 contacts with oil stains, it will become brittle due to deterioration, so there is a shortcoming that the anti-slip handle sheath 20 is damaged and loses the anti-skid effect

[0008] In addition, in the second to fourth embodiments of the existing structure, the anti-skid design is not directly designed on the wrench body 10, but the upper and lower fixing grooves 111, 112 are additionally set on the wrench body 10, or a The perforated hole 113 or the threaded hole 114 are used to respectively install the non-slip handle sheaths 20 and 20' of different structures. Such a complicated structural design will cause a burden on the production cost and cannot really solve the slippage of the wrench body 10. The problem is quite inconsistent with industrial application, so it is necessary to develop and improve
