Abstract
A three-jaw holding spanner consists of an adjusting conical head, a housing, a fixed bolt, jaws, a packing and a handle, wherein the packing is arranged in the housing; the upper end surface of the packing is a conical surface structure; the fixed bolt fixed with the housing is arranged in the middle position of the conical surface structure of the packing; a taper tooth surface is arranged on the conical surface; a spiral screw thread is arranged on the lower end surface of the packing; three jaws are arranged on the periphery of the spiral screw thread and uniformly meshed with the spiral screw thread; the handle is arranged on one side of the housing; a through hole is arranged at the center of the handle; and the adjusting conical head meshed with the conical surface of the upper end surface of the packing is arranged in the through hole. The utility model has the advantages of simple and convenient operation, and convenient use, and solves the problem that a sleeve type spanner and a common spanner are often found absent and inconvenient to use. When the three-jaw holding spanner is in use for loosening or tightening operation, the clearances among the three jaws are adjusted by using the adjusting conical head according to the size of the object to be held, and until the clearances among the three jaws are so proper as to be suitable for the object to be held, all that is needed is to spin the handle.
Description
Technical field:
The utility model relates to a kind of spanner, relates in particular to a kind of three-pawl type clamping spanner.
Background technology:
When using box spanner of the prior art, need carry the sleeves of more different sizes, when nuts that run into different sizes or bolt, will constantly change sleeve in the work, use trouble, when losing a certain sleeve, also can bring certain trouble to work; Common spanner just must be changed the direction of spanner, inefficiency when pulling nut or bolt and turn to certain angle.
The utility model content:
The purpose of this utility model is, overcomes the deficiencies in the prior art part, provides a kind of easy and simple to handle, but the three-pawl type clamping spanner of regulated at will size easy to use.
Three-pawl type clamping spanner described in the utility model, including shell, packing, handle, claw and set bolt constitutes, be provided with packing in the enclosure, the upper surface of said packing is the taper surface structure, in the centre position of taper surface structure, be provided with and the fixing set bolt of shell, taper surface is provided with the tapering flank of tooth, the lower surface of said packing is provided with the screw thread that spirals, and is provided with three claws with the even interlock of screw thread of spiraling around the said screw thread that spirals.Side at said shell is provided with handle, and said handle center is provided with a through hole, is provided with the adjusting conehead with the taper surface interlock of packing upper surface in through hole.
A kind of three-pawl type clamping wrench operated described in the utility model is easy, easy to use, has solved that telescopic spanner and common wrench are easily lost, awkward problem.When carrying out degree of tightness work with three-pawl type clamping spanner, can be according to the size that is held part, earlier by regulating the size between the conehead adjusting three-jaw, when the suitable size between the three-jaw is held part, rotary handle gets final product, the degree of tightness of six square nuts in this three-pawl type clamping spanner is also suitable.
Description of drawings:
Accompanying drawing is the structural representation of a kind of three-pawl type clamping spanner described in the utility model.Accompanying drawing 1 is a structural representation of analysing and observe state; Accompanying drawing is the structural representation of side-looking state.1-adjusting conehead, 2-shell, 3-set bolt, 4-claw, 5-packing, 6-handle
The specific embodiment:
Referring now to accompanying drawing 1 and accompanying drawing 2, be described as follows in conjunction with the embodiments: a kind of three-pawl type clamping spanner described in the utility model, include and regulate conehead 1, shell 2, set bolt 3, claw 4, packing 5 and handle 6 formations, in shell 2, be provided with packing 5.The upper surface of said packing 5 is the taper surface structure, centre position in packing 5 taper surface structures, be provided with the set bolt of fixing with shell 23, taper surface is provided with the tapering flank of tooth, the lower surface of said packing 5 is provided with the screw thread that spirals, and is provided with three claws 4 with the even interlock of screw thread of spiraling around the said screw thread that spirals.Side at said shell 2 is provided with handle 6, and said handle 6 centers are provided with a through hole, is provided with in through hole and the taper surface of the packing 5 upper surfaces adjusting conehead 1 of interlock mutually.A kind of three-pawl type clamping wrench operated described in the utility model is easy, easy to use, has solved that telescopic spanner and common wrench are easily lost, awkward problem.When carrying out degree of tightness work with three-pawl type clamping spanner, can be according to the size that is held part, earlier by regulating the size that conehead 1 is regulated between the three-jaw, when the suitable size between the three-jaw is held part, rotary handle 6 gets final product, the degree of tightness of six square nuts in the said three-pawl type clamping of the utility model spanner is also suitable.
