There is considerable difficulty in manufacturing because it has a complicated structure in which a means for restraining the movement of the lever and a means for restoring the outer side of the fixing plate and an mounting rod for fixing the lock body and the other fixing plate are formed inside. .

In other words, there is a complexity in the design process of the mold for forming the fixed plate, but the considerable difficulty in the molding process, as well as the initial design provides a cause for the increase in manufacturing cost.

Particularly, in the case of the mounting rod, the mounting rod is integrally formed or separately formed and fixed to the fixing plate. The mounting rod is accommodated in the lock body, and the fastening bolts are coupled to each other through the fixing plate on the other side. It will be fixed firmly.

However, in order to couple the fastening bolts to the mounting rods inserted into the lock body, the coupling bolts are fastened through the coupling holes formed in the lock body, which makes it difficult to match the coupling holes of the fastening bolts and the mounting rods.

In order to solve the difficulty of fastening, the screw may be formed on the body spindles protruding to both sides of the lock body, and may be fastened by forming a screw on the fixing plate or the fixing plate which closes the inner side of the fixing plate.

In this case, the ease of fastening can be provided, but there are a number of problems, such as a decrease in productivity and cost burden due to a separate process of forming screws.

Therefore, the present invention is designed to solve the above problems, by improving the fixing plate that the lever is coupled to the outside and the lock body to the inside to prevent the return and over-rotation of the lever to facilitate the mounting with the lock body The aim is to improve productivity and assembly.
