Abstract

A bolt disassembling tool comprises a steel pipe, two embedded screws fixed at one end of the steel pipe, a knocking head formed at the other end of the steel pipe, a drill bit accommodated in the steel pipe and a sleeve fixedly connected with the drill bit. The utility model discloses an usable impact force of bolt extracting tool dismantles the bolt, has solved because of unable extension bar and the problem of "L" type spanner dismantlement bolt of using, convenient to use. The disassembly process is simple, manpower and material resources are saved, and the disassembly of additional equipment is reduced.

Description

Bolt disassembling tool

Technical Field

The utility model relates to a extracting tool especially relates to a bolt extracting tool.

Background

The bolt often needs to be dismantled in the maintenance work, but has some bolt positions complicacy, can't use "L type" spanner to dismantle or use the spanner comparatively to turn round, and difficult dismantlement after the bolt is tightened can't use the extension bar, can only dismantle the equipment rear that near hinders and can go on, and the process is comparatively complicated, extravagant manpower and material resources.

Disclosure of Invention

The utility model overcomes prior art's is not enough, provides a convenient to use's bolt extracting tool.

In order to achieve the above purpose, the utility model adopts the technical scheme that: a bolt disassembling tool comprises a steel pipe, two embedded screws fixed at one end of the steel pipe, a knocking head formed at the other end of the steel pipe, a drill bit accommodated in the steel pipe and a sleeve fixedly connected with the drill bit.

The utility model discloses an usable impact force of bolt extracting tool dismantles the bolt, has solved because of unable extension bar and the problem of "L" type spanner dismantlement bolt of using, convenient to use. The disassembly process is simple, manpower and material resources are saved, and the disassembly of additional equipment is reduced.

Drawings

The present invention will be further explained with reference to the drawings and examples.

FIG. 1 is an assembled view of a bolt removal tool according to a preferred embodiment of the present invention;

FIG. 2 is an exploded view of the bolt removal tool of FIG. 1;

in the figure: 1. a steel pipe; 2. embedding screws; 3. a knocking head; 4. a drill bit; 5. a sleeve.

Detailed Description

The invention will now be described in further detail with reference to the accompanying drawings, which are simplified schematic drawings and illustrate, by way of illustration only, the basic structure of the invention, and which therefore show only the constituents relevant to the invention.

As shown in fig. 1 and 2, the bolt disassembling tool according to a preferred embodiment of the present invention includes a steel pipe 1, two embedded screws 2, a striking head 3, a drill 4, and a sleeve 5. All components of the bolt removal tool are made of steel material.

Two through holes are drilled up and down at the position, close to one end, of the steel pipe 1 by using a drilling machine, and the two embedded screws 2 are embedded into the two through holes of the steel pipe 1 and then fixed on the steel pipe 1 by welding. Two embedded screws 2 are arranged on the steel pipe 1 opposite to each other, and a gap is reserved between the two embedded screws 2 at the inner side of the steel pipe 1 so as to meet the requirement that spiral textures of the drill bit 4 enter and are led out through the embedded screws 2. The drill 4 is accommodated in the steel pipe 1 and clamped between two embedded screws 2 on the steel pipe 1. The other end of the steel pipe 1 is welded with an upper blocking plate to form the knocking head 3, so that the hammering by a hammer is facilitated. One end of the drill 4 and the sleeve 5 are fixedly connected together by welding, and the drill 4 and the sleeve 5 are integrally sleeved into the steel pipe 1 for use.

The helical texture of the drill 4 is retractable inside the steel pipe 1 by means of the embedded screw 2. A hexagonal socket head is inserted into the socket 5 and a hexagonal socket wrench is inserted onto the bolt to be removed. Use the hammer hammering to strike head 3, the impact force transmits simultaneously for drill bit 4 and interior hexagonal spanner, and when hammering struck head 3 promptly, interior hexagonal spanner drives the bolt rotation that needs the dismantlement simultaneously through 4 texture contractions of drill bit, reaches the purpose of dismantling the bolt.

The utility model discloses an usable impact force of bolt extracting tool dismantles the bolt, has solved because of unable extension bar and the problem of "L" type spanner dismantlement bolt of using, convenient to use.

The sleeve 5 of the above embodiment is an internal hexagonal sleeve, and an internal hexagonal wrench (the cross section of the wrench is a regular hexagon) is installed in the sleeve 5. The utility model discloses a bolt extracting tool technique extensibility is extensive. It will be appreciated that the bolt removal tool can be removed for different bolts by changing the form of the sleeve 5 to accommodate the installation of a screwdriver bit or other tool.

In light of the foregoing, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
