Connector for socket wrench

This creation is related to a connector of a tool, and in particular to a connector for a socket wrench.

Generally, a pneumatic tool or a power tool can provide greater power to improve work efficiency. When a screw is locked or loosened, it is fitted with a sleeve to fit the screw, and the screw is sleeved at one end of the sleeve. The other end of the sleeve is provided with a protruding joint for connecting a pneumatic tool or a power tool to drive the sleeve to rotate. Generally, the protruding joint has a cross-sectional area smaller than the sleeve. The cross-sectional area of the position, that is, the protruding joint is a small head, and the sleeve is a large head.

The early sleeve is integrally formed with a protruding joint. Since a torque is output from the small head to the big end, there is stress concentration at the intersection of the protruding joint and the sleeve. After the sleeve is used for a period of time, The protruding joint will break at the junction and the sleeve will not be used.

Further, a protruding joint and a sleeve are designed as a separate structure, in other words, the protruding joint and the sleeve are two separate components, and the sleeve is provided with a square hole to receive the square protruding joint. A protruding structure is disposed between the protruding joint and the sleeve, and when the protruding joint is broken, a new protruding joint can be replaced, but if the protruding joint breaks is located inside the square hole , it is the case that it is not easy or impossible to disassemble the protruding joint.

The main purpose of this creation is to provide a connector for a socket wrench that can replace the connector immediately and easily.

A secondary objective of the present invention is to provide a connector for a socket wrench that has better strength.

A further object of the present invention is to provide a connector for a socket wrench that reduces man-hour costs and component costs.

Therefore, in order to achieve the foregoing purpose, the present invention provides a connector for a socket wrench, the connector includes at least a first portion, a second portion and a convex portion, and the first portion has a first end a connecting portion for connecting a power output end of a driver for driving the first portion to rotate corresponding to a rotating shaft, the second portion being formed by extending the other end of the first portion, the second portion being The first portion is coupled to the rotating shaft for rotation, and is provided with a second connecting portion for connecting to one end opening of the female seat for interlocking the female seat to rotate corresponding to the rotating shaft, the protruding portion is configured The first portion and the second portion are located outside the female seat opening, wherein the convex portion can abut the side of the female seat or not abut the side surface of the female seat.
