Abstract

This cutting pliers is comprised of pinching part (1), angle part (2) for cleaning of a welding torch, face part (3) for cleaning of a welding torch, hammer face (4), cutting edge (6), two grip parts (5,7) for gripping of tip and nozzle of a welding torch.

Description

    BACKGROUND OF THE INVENTION (1) Field of Invention
  • The present invention relates to a cutting pliers which can be utilized for cleaning and changing of parts of welding torch which be used about gas shielded arc welding, inert gas arc welding and so on.
    • (2) Prior Art
  • Generally, welding torch which is utilized for welding like gas shielded arc welding is cleaned and/or changed the parts before the use.
  • Conventionally, tools as prior art for cleaning and changing of parts of welding torch are known to use together with several kind of tools,that is,cutting pliers, cutting nippers, screw driver or steel bar etc.. For example, cutting pliers or cutting nippers have mainly cut a wire of welding torch, and it is difficult to clean inside face of nozzle, to change nozzle,insulated part or tip by these tools. Screw driver or steel bar has mainly cut off spatters adhered on inside face,outside face and end face of nozzle of welding torch. But screw driver and steel bar are apt to hurt nozzle. Consequently, life of welding torch have be shorten.
  • Thus, with regard to cleaning and changing of welding torch, unitary tool which is useful is not known.
    • BRIEF SUMMARY OF THE INVENTION
  • It is an object of the present invention to provide a cutting pliers which be capable of cleaning and changing of parts of welding torch by a unit.
  • To accomplish the above object, a cutting pliers is comrised of pinching part for pinching and pulling, angle part for cleaning, face part for cleaning, hammer face for striking, cutting edge and two gripping parts that be different in size.
    • BRIEF DESCRIPTION OF THE DRAWINGS
    • Figure 1 is a perspective view of an embodiment of the present invention.
    • Figure 2 is a plan view thereof.
    • Figure 3 and 4 are perspective views thereof in explaning the operation of the invention. Figure 3 shows the operation about changing nozzle of welding torch. Figure 4 shows the operation about changing tip of the welding torch by small gripping part and cutting wire of welding torch by cutting edge.
    • Figure 5 to 7 are partial diagrammatic view thereof in explaning the operation of the invention. Figure 5 shows about cleaning of inside face of nozzle by angle part. Figure 6 shows about cleaning of inside and outside faces of nozzle by pinching part. Figure 7 shows about cleaning of end face of nozzle by face part.
    DETAILED DESCRIPTION OF PREFERD EMBODIMENT
  • Refering to the drawings as Figure 1 and 2, a pair of cutting pliers has pinching part 1,angle part 2,face part 3 for cleaning of the end face of nozzle 11 of welding torch 10,hammer face 4, small gripping part 5 for tip 12 of welding torch 10, cutting edge 6, big gripping part 7 for nozzle 11 of welding torch 15, spring 8 and handle 9.
