Description

Variable type socket}

The present invention relates to a variable socket, and more particularly, to a socket wrench used when loosening or tightening various bolts or nuts.

A socket wrench is composed of a socket and a handle, and is mainly used when loosening or tightening bolts and nuts according to the size of the socket and the industrial field. Conventionally, socket sets were required to fasten hexagon nuts of various sizes, hexagon jam nuts for connectors, hexagon bolts, and the like, and there was inconvenience such as requiring a large space to store them.

Due to these problems, a prefabricated box socket wrench, etc., was developed to reduce the volume of the tool holder. However, the need for disassembling or assembling the corresponding socket in order to use a box socket of the required size was required, thus limiting the rapid use of the tool.

In addition, although hexagonal fasteners of various sizes can be assembled or disassembled with a monkey spanner, there is a problem that a socket box is essential when the fasteners are adjacent and there is an obstacle in the range of rotation of the spanner handle.

The matters described as the above background art are only for improving the understanding of the background of the present invention, and should not be taken as acknowledging that they correspond to the prior art already known to those of ordinary skill in the art.
