Abstract

The utility model relates to a universal spanner, which is composed of a single pincers hook, a double-pincers hook, a handle and a cylindrical pin. The utility model is characterized in that one end of the handle is provided with a spanner device; the other end is provided with a spanner scissors and a spanner devices. The wrenching, tonging, and cutting of workpieces with various shapes can be carried out effectively by the spanner. The spanner forms integration of the functions of wrenching, pipe wrenching, cutting, etc. The utility model has the advantages of simple structure, easy fabrication, complete functions, and low cost. Thus, the utility model is good for mechanization mass production and meeting the requirements of convenient use of people.

Description

The general-purpose wrench

The utility model relates to a kind of wrench instrument

At present, the spanner of use, pliers, function singleness.They are in degree of tightness, when pincers are cut workpiece, and the defective of existence is: fork spanner is the workpiece of degree of tightness single size, specification only; Monkey wrench and pliers, degree of tightness is less with the scope that clamps the dimensions of cutting workpiece, and makes workpiece slippage and mill lose corner angle easily.

At above-mentioned deficiency, the utility model provides a kind of spanner, pipe wrench, pincers of integrating function such as to cut, and degree of tightness, pincers are cut the big general-purpose wrench of workpiece size scope.Its advantage is: simple in structure, with low cost, function is many, the many usefulness of pincers, makes people in use, selects to pull, twist, clamp, to shear workpiece according to purposes.

For realizing this purpose, the technical solution of the utility model is:

A kind of general-purpose wrench.Connect and compose by the two pincers hooks of single, double pincers hook or two and handle and garden pin or screw thread pivot pin.An end that it is characterized in that handle is provided with the wrench device, the other end be provided with pull cut, clamp device.The handle two ends all are made as two arcs, and are equipped with the hole, garden, are equipped with teeth on two arcs limit of an end, one side the teeth another side that is provided with of the two arcs of the other end is provided with arc scissors; One end of single pincers hook is provided with hole, connection garden, and the inboard of single pincers hook is made up of 4 medial surfaces; The middle part of two pincers hooks is provided with hole, connection garden, and the inboard of two pincers hooks is made up of 7-9 medial surface; Single pincers hook, two pincers hook combine with handle, be to couple together by garden pin or screw thread pivot pin, because single pincers hook, two pincers hook combine with handle, be to connect by garden pin or screw thread pivot pin, so single pincers hook and two pincers hook all are active, so as long as the pincers hook hooks workpiece, pull the handle card and press workpiece to rotate, can reach free degree of tightness, clamp the purpose of cutting the various sizes workpiece.

Structure of the present utility model is provided by the following drawings and embodiment.

The figure one of accompanying drawing is the structural representation according to the utility model embodiment.

The figure two of accompanying drawing is the structural representation of another embodiment.

Below in conjunction with concrete structure and the details of accompanying drawing detailed description according to the general-purpose wrench that the utility model proposes.

The general-purpose wrench is by single pincers hook (8) two pincers hooks (1) wrench handles (2) and garden pin (3) or screw thread pivot pin formation.Two ends of handle (2) are two arcs, and two ends respectively are provided with hole, a garden.One end is equipped with teeth (4) on two arc limits; One arc limit of the two arcs of the other end is provided with another arc limit of teeth (7) and is made as arc scissors (6).One end of single pincers hooks (8) is provided with hole, connection garden, and the garden nose end head of single pincers hooks (8) is provided with the groove of being convenient to handle (2) rotation to being shown in dotted line part, and groove width and tiller grip thickness coincide, and single pincers hooks (8) are inboard to be made up of four medial surfaces; The middle part of two pincers hooks (1) is provided with hole, connection garden, and two pincers hooks (1) are inboard to be made up of 7-9 medial surface; The hole to two, connection garden of two pincers hooks (1) is shown in dotted line part, is provided with to be convenient to the movable groove of handle (2), and groove width and tiller grip thickness coincide.Handle (2) is connected by garden pin (5) riveted joint or Luo line with single the pincers between hook (8) or the two pincers hook; Rivet by garden pin (3) between handle (2) and the two pincers hooks (1) or be threaded.During use, will clamp hook (1) or (8) earlier and hook workpiece, and pull handle (2) card then and press workpiece to rotate, and can reach degree of tightness, clamp the purpose of cutting workpiece, and oppositely pull handle (2) slippage then and take out.
