Abstract
The present invention relates to a lock nut of a new structure that can be easily released as needed.
When the lock nut according to the present invention is coupled to the threaded portion 1a of the bolt 1, the coil spring 20 is opened and the tip portion is rotated along the opening, so that the coil spring 20 is suitable for the circumference of the bolt 1. It is fixed by pressing elastically so as not to loosen, and when the box 30 is coupled to the outside of the nut body 10, the coil spring 20 is pushed back by the coupling hole 31 of the box 30, the coil spring Since the inner diameter of (20) is widened, the coupling force between the coil spring 20 and the threaded portion 1a of the bolt 1 is weakened, so that the lock nut can be rotated and released.

Description
The present invention relates to a lock nut of a new structure that can be easily released as needed.
Generally, nuts are screwed into bolts and used to secure two or more different members to each other.
On the other hand, in recent years, lock nuts have been developed and widely used to prevent unintentional loosening of nuts in a state where nuts and bolts are coupled.
