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 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.

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

3. The connector for a tool in accordance with claim 1, wherein the body has one end provided with a drive body having a form of a ratchet wheel.

4. The connector for a tool in accordance with claim 3, wherein the body has a rectangular locking end formed on and protruded from a center of the drive body.

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

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

7. The connector for a tool in accordance with claim 1, wherein the urging body has an outer wall formed with a drive portion that is in the form of an anti-skid friction face, thereby increasing a driving force of the user'"'"'s hand on the urging body.

8. The connector for a tool 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.

9. The connector for a tool in accordance with claim 1, wherein the engaging portion of the urging body is in the form of a threaded column extended downward, the engaging portion of the drive end of the body is in the form of an inner thread, whereby the engaging portion of the urging body may be screwed in the engaging portion of the drive end of the body.

10. The connector for a tool in accordance with claim 1, wherein the urging body is provided with a stepped urging portion rested on a top face of the tool, the drive end of the body is provided with a flange-shaped urging portion rested on a bottom face of the tool, so that the tool may be urged between the urging portion of the urging body and the urging portion of the drive end of the body.

11. The connector for a tool in accordance with claim 10, wherein the urging body has a rotation disk formed on and protruded from a bottom of the urging portion of the urging body, and the rotation disk has an outer diameter exceeding that of the tool, so that the user may rotate the rotation disk.

12. The connector for a tool in accordance with claim 1, wherein the drive end of the body has an outer wall provided with multiple locking members, and the tool is formed with recessed locking portions for locking the locking members of the drive end of the body, thereby preventing the tool from detaching from the drive end of the body in a horizontal direction.

13. The connector for a tool in accordance with claim 1, wherein the further comprising a locking member having a ring-shaped mounting portion mounted on an outer wall of the drive end of the body and having an inner wall provided with two opposite locking portions, wherein the tool is formed with two opposite recessed locking portions for locking the locking portions of the locking member, thereby preventing the tool from detaching from the drive end of the body in a horizontal direction.

14. The connector for a tool in accordance with claim 1, wherein the further comprising a locking member having a ring-shaped mounting portion mounted on an outer wall of the drive end of the body and provided with a T-shaped extension formed with two hook portions hooking an outer edge of the tool, thereby preventing the tool from detaching from the drive end of the body in a horizontal direction.
