Abstract

The present invention relates to a nut screw release aid, wherein the nut screw release aid is damaged when the nut screw thread is damaged when the nut is released, and the nut screw release aid is located in a narrow space when there is no space to use a tool such as a spanner. It is a nut screw release aid characterized in that it is fixed to the nut screw and integrated to make it easy to transmit torque.

Description

Nut Screw Removal Tool

The present invention relates to a nut screw release aid.

A wrench is used to release the nut screw. However, when the screw of the nut screw is damaged and the shape is deformed, and when it is located in a narrow space and there is no space to use a tool such as a spanner, the torque cannot be properly transmitted by the wrench, which causes difficulty in releasing the nut screw. Occurs. Conventional methods for solving this problem include lubricating and hacking with a hacksaw or file to turn the screw head into a spanner. However, the conventional methods have a problem that the nut screw is likely to damage an object to which the nut screw is attached and is located in a narrow area, and there is not enough space to use a tool such as a spanner and is troublesome to perform.

The object of the present invention devised to solve the above problems is to secure the space for use of a tool such as a spanner, even when located in a narrow place without damaging the object to which the nut screw is attached to release the nut screw without troublesome to perform The present invention provides a technique for nut screw release assist.

The nut screw release aid of the present invention for achieving the above object is an outer portion that has a shape that is good for the blade and the nut can be fixed by inserting the nut screw and the thread of the nut screw can be fixed by cutting. Characterized in that made.

In addition, the nut screw release aid according to the present invention is characterized in that the diameter of the through hole is narrowed in one direction in order to increase the effect of tightening after mounting the nut screw to be released integrally.

In addition, the nut screw release aid according to the present invention is characterized in that the diameter of the through hole has a stepped slope in order to be able to be used for various sizes of nut screws.

As described above, the present invention transmits torque through the outer portion of the nut screw release aid, not the thread of the nut screw, so that the nut screw can be easily released and the long nut screw release aid when the nut screw is located in a narrow space. Use to secure space for the spanner to easily release the nut screw.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a nut screw release aid according to the present invention.

As shown in Figure 1, the nut screw release aid 10 according to the present invention is provided with a through-hole 12 that can be fixed integrally with the nut screw release aid by mounting the nut screw to be released In addition, the surface of the through hole 12 is a blade 13 for cutting the thread on the outer surface of the nut screw to be mounted and fixed integrally formed in the shape of a thread, the diameter of the through hole 12 The inner side becomes narrower as you go in, so that the screw to be released can be tightened well. The outer surface of the nut screw release aid itself is, for example, formed with an angle 11 of the outer portion so that torque can be transmitted well from the outside.

The target nut screw is inserted into the through hole 12, and is cut and fixed by the threaded blade 13. In that state, torque is easily transmitted through the angle 11 of the outer portion to release the nut screw.
