Trachea cutting forceps

Abstract

The trachea cutting forceps comprise a first forceps body and a second forceps body, the first forceps body comprises a supporting end and a first forceps handle which are connected with each other, and the second forceps body comprises a cutting end and a second forceps handle which are connected with each other; the first forceps handle and the second forceps handle are rotationally connected through a connecting shaft, the supporting end and the cutting end are matched to form a forceps mouth capable of cutting off a trachea, the supporting end is provided with an arc-shaped supporting surface which is in a convex arc shape, the arc-shaped supporting surface supports the trachea, the cutting end is provided with two clamping arms and a blade, the blade is arranged between the two clamping arms, and the clamping arms are connected with the cutting end. The clamping end of the clamping arm abuts against the air pipe, the air pipe is extruded and deformed to form an arc-shaped air pipe, and the blade abuts against the arc-shaped air pipe. According to the trachea cutting forceps, the arc-shaped supporting face is arranged at the supporting end, the trachea on the arc-shaped supporting face is in a radian shape through extrusion of external force, the blade correspondingly makes contact with the arc-shaped trachea, and cutting is convenient, easy and labor-saving.

Description

technical field [0001] The present application relates to the field of hardware tools, in particular to a trachea cutting pliers. Background technique [0002] Industrial pneumatic air pipes are widely used, mostly using polyurethane and nylon materials, with stable quality, high strength and pressure resistance, wear resistance, bending resistance, and not easy to cut. However, in the process of use, it is often necessary to cut industrial pneumatic air pipes, such as assembling and designing some pneumatic equipment and pneumatic fixtures. When maintaining such equipment on site, the air pipes on the equipment need to be replaced many times. Need to size, need to cut the trachea. [0003] At present, the commonly used tracheal cutting tools are blades, scissors, ordinary cutting pliers, laser cutting, high-pressure water cutting, etc. Due to the high strength and pressure resistance of tracheal materials, these cutting tools are not easy to cut when cutting the trachea. ...

AI Technical Summary

Problems solved by technology

[0003] Currently commonly used trachea cutting tools are blades, scissors, ordinary scissors, laser cutting, high-pressure water cutting, etc. Due to the high strength and pressure resistance of the trachea material, these cutting tools are not easy to cut when cutting the trachea

When cutting with blades and scissors, the blade blade is straight, the contact area between the straight edge and the surface of the trachea is large, the pressure distributed on the blade is small, and the cutting is not easy; when cutting with ordinary scissors, it is convenient to cut the smaller diameter and thicker pipe wall. Thin trachea, but it is not easy to cut a trachea with a large diameter and a thick tube wall; when cutting with laser equipment, the equipment is relatively large, and it is easy to generate dust and combustion exhaust gas, so it is not suitable for purification of workshop equipment; when using high-pressure water cutting, the equipment is relatively large, Produce waste water, not suitable for purification workshop configuration
