Description

Wrench socket

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wrench socket, and more particularly, to a wrench socket that is connected to a torque wrench with a tool having a square cross section fixed.

A torque wrench is a tool that tightens bolts, nuts, and screws.

Korean Patent Laid-Open No. 10-2009-0125581 (published December 21, 2009, hereinafter referred to as "the present document") discloses a torque wrench.

The torque wrench of this document comprises a socket to which a workpiece is coupled and a handle to be connected to the socket. The socket has a single-ended shape and an insertion groove is formed at both ends. The insertion groove has a hexagonal groove shape. This is for restricting the rotation of the workpiece having a hexagonal periphery to tighten or loosen the workpiece. The handle is configured to be elongated in the longitudinal direction to impart a sufficient moment to the socket.

At this time, the socket is formed corresponding to the size of the workpiece such as a bolt, a nut, and a screw. It is necessary that the insertion groove of the socket and the size of the work object correspond to each other so that the work object can transmit sufficient torque. Accordingly, the handle and the socket are detachably coupled and separated from each other, and a plurality of sockets may be provided for various sizes.

The operator can select and use a socket having a size corresponding to the size of the object to be mounted on the handle.

However, these torque wrenches have a plurality of sockets in addition to the sockets coupled to the handle, so there is a great risk of losing the sockets.
