Abstract

A connector includes a body provided with a polygonal drive end that may be driven by a tool, the drive end provided with an engaging portion, and an urging body secured on the drive end of the body, and provided with an engaging portion engaged with the engaging portion of the drive end of the body, so that the tool is urged and secured between the urging body and the drive end of the body. Thus, the body of the connector and the tool may be combined integrally, whereby the connector may be exactly secured on the tool, so that the tool may function as a ratchet wrench.

Claims

1. A connector comprising:

a body provided with a drive end that can be driven by a tool, the drive end provided with an engaging portion;

an urging body secured on the drive end of the body, and provided with an engaging portion engaged with the engaging portion of the drive end of the body, so that the tool is urged and secured between a bottom of the urging body and a top of the body; and

a locking member mounted on the top of the body and having a ring-shaped mounting portion fixed on an outer wall of the drive end of the body, the mounting portion being provided with two opposite protruding locking portions, wherein;

the tool is formed with two opposite recessed locking portions secured on the locking portions of the locking member, thereby preventing the tool from detaching from the drive end of the body in a horizontal direction.

2. The connector in accordance with claim 1, wherein the body has an outer periphery formed with a friction face such that a user can directly rotate the body by his fingers in a frictional manner.

3. The connector in accordance with claim 1, wherein the drive end of the body has a center formed with a rectangular drive recess.

4. The connector in accordance with claim 1, wherein the engaging portion of the drive end of the body is an outer thread, and the engaging portion of the urging body is an inner thread screwed on the outer thread of the engaging portion of the drive end.

5. The connector in accordance with claim 1, wherein the urging body has an outer wall formed with a drive portion that is an anti-skid friction face.

6. The connector in accordance with claim 1, wherein the urging body has a bottom formed with a recessed extension portion having an inner diameter greater than that of the engaging portion of the urging body.
