Description

A kind of special pliers for leather pegboard

technical field

The utility model relates to a hand tool, in particular to a special pliers for leather nail boards.

Background technique

In the current tanning process, peg board drying is still widely used for small leathers, especially special leathers with high surface pattern requirements, such as crocodile skin, sturgeon skin, pearl fish skin, etc. Nail board drying is a method of fixing leather with nails for drying. Compared with ordinary stretch board drying, nail board drying has many advantages. It can adjust the flatness of leather to the greatest extent and increase the yield of leather. It is a special Preferred drying method for leather processing.

However, in the peg board process, there is still no suitable leather traction and stretching tool. At present, the pliers used in the nailing process of tanneries have not been improved. The teeth of the pliers are relatively smooth, and the heads and handles of the pliers have not been specially designed. If the length is not enough, it is easy to slip during the process of stretching the wet leather. At the same time, the strength of the worker's hand is very high, and it is very easy to get tired. Therefore, it is urgent to redesign and improve the existing traction and stretching tools, which is of great significance to reduce the fatigue of workers and realize the efficient processing of leather.

Contents of the invention

In order to solve the existing technical problems, the purpose of this utility model is to provide a special pliers for leather nail boards, which solves the problem that the teeth of the pliers used in the leather nail board process are smooth and slippery, and the handles of the pliers are time-consuming and labor-intensive without improvement. , Nail board efficiency is low, operators are prone to fatigue and other problems.

In order to achieve the above object, the technical scheme of the utility model is:

A kind of special pliers for leather nail boards, comprising a first pliers handle and a second pliers handle hinged to each other through a pliers shaft, the top ends of the first pliers handle and the second pliers handle are respectively connected with a first pliers mouth and a second pliers mouth, the The first pliers handle is S-shaped; the second pliers handle is back-shaped; the first pliers mouth and the second pliers mouth are tapered, and the inside of the first pliers mouth and the second pliers mouth are provided with a direction toward The pliers teeth in the direction of the pliers axis; the outer sides of the first pliers mouth and the second pliers mouth are provided with vertical edges.

Both the outer sides of the first tong handle and the second tong handle are sheathed with an insulating plastic layer.

The vertical rib is wide at the bottom and narrow at the top, and its structural form is convex.

The beneficial effects of the utility model are:

1. The design of the S-shaped pliers handle of the utility model makes the pressing grip of the thumb provide the main occlusal force in the occlusal process of the pliers mouth during work, and at the same time the thumb can also provide a certain pulling force by means of the arc shape;

2. The design of the back-shaped pliers handle of the utility model fully realizes the traction effect of the four fingers, which can generate outward pulling force along the plane where the leather is located, improve the elongation rate of the leather, and at the same time easily open the pliers handle to improve work efficiency;

3. The special orientation design of the teeth of the utility model can increase the friction between the teeth and the leather, and there will be no slippage during work;

4. Through the "convex" vertical edge design on the outside of the front end of the pliers, it can reduce the deformation of the pliers under the working state and enhance the stability of the bite;

5. Using the leather pegboard pliers in this utility model to carry out the nailboard process can overcome the problem of workers' fatigue, improve the elongation rate of leather, and improve work efficiency.
