Abstract

The utility model discloses a broken screw withdraw device which comprises a rod body (1), and is characterized in that a reverse thread drill bit (3) is arranged at the front end of the rod body (1); and a screwing device, which is a handle (2) arranged on the rod body (1) radially, is arranged on the rod body (1) at the rear end of the reverse thread drill bit (3). Compared with the prior art, the broken screw withdraw device has the advantages that the structure is simple; the use is convenient; and a broken screw in a threaded hole can be taken out under the condition of not damaging the threaded hole.

Description

A kind of fracture of wire withdrawing device

Technical field

The utility model relates to a kind of device of dismantling screw, especially a kind of fracture of wire withdrawing device for the disconnected screw of dismounting.

Background technology

Enterprise is in carrying out ordinary maintenance to machinery equipment; due to screw quality or dismounting during screw the reason such as overexertion often can run into holding screw from problems such as hexagonal (hexagon)nut fractures; how a hole site can not changed; do not destroy again in the situation of internal thread fracture of wire is taken out, become the new problem that runs in the machinery equipment maintenance.

Therefore, a kind of hole of not destroying, the fracture of wire withdrawing device that can take out the disconnected screw in a hole is suggested.

Summary of the invention

The purpose of this utility model is to provide a kind of device of dismantling screw, especially a kind of fracture of wire withdrawing device for the disconnected screw of dismounting.

The utility model comprises the body of rod (1), it is characterized in that the body of rod (1) front end is provided with minus thread drill bit (3), the body of rod (1) of minus thread drill bit (3) rear end is provided with screwing device, and screwing device is one and is the handle (2) that radially is arranged on the body of rod (1).

As improvement, above-mentioned screwing device is that a cross section is square or hexagon.

As improvement, the body of rod (1) of above-mentioned minus thread drill bit (3) rear end is provided with external screw thread (5) and can be at the demounting bolt (6) of the upper rotation of this external screw thread (5).

Compared with prior art, the utility model is simple in structure, and convenient the use can be in the situation that do not destroy a hole the disconnected screw in the silk hole is taken out.
