Abstract
The utility model discloses a special tool for extracting broken screws, which is composed of a body with a large end and a small end, wherein the small end face of the body is a quadrilateral plane, and the taper of the small end of the body is 1.5: 60. Compared with the prior art, the utility model has the advantages of simple structure, convenient use, etc., and solves the problem that the broken screws affect the operation of replacing components, etc.
Description
Technical field:
The utility model relates to a kind of maintenance of machine instrument, and especially a kind of broken end screw takes out specific purpose tool.
Background technology:
At present, in the I﹠M process of equipment, pipeline etc., screw broken end phenomenon often taking place, in case broken end can't take out screw routinely, makes troubles to work, even take out also fragile original screw thread.
The utility model content:
The purpose of this utility model is in order to address the above problem, to provide a kind of fracture of wire simple in structure to take out specific purpose tool.
The utility model adopts following technical proposals: a kind of fracture of wire takes out specific purpose tool, is made up of the little main body of the big end of an end, and the small end face of main body is a quadrangular plan.
The tapering of main body small end is 1.5: 60.
The utility model compared with prior art is simple in structure and convenient in use, and has solved because of problems such as broken end screw influence replacing parts.
Description of drawings:
Fig. 1 is the utility model structural representation
Fig. 2 implements state diagram for the utility model
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, a kind of fracture of wire takes out specific purpose tool, is made up of the little main body 1 of the big end of an end, and 2 of the small ends of main body are quadrangular plan.
The tapering of main body small end 2 is 1.5: 60.
When the screw broken end takes place, make a call to a hole 4 by the drill bit of corresponding specification on broken end screw 3 earlier, then 2 ones of small ends of the present utility model are rapped in the hand-hole 4, as shown in Figure 2, utilize the shearing force at 2 four angles of small end, reverse rotation can be taken out the broken end screw.
