Abstract

A connection compensating device of multiangular wrench socket, including a main body and a connecting section. The main body is a cylindrical body. The outer circumference of the main body between two ends thereof is formed with several radially arranged flutes which extend along a circular axis by a certain length. The flutes have different cross-sectional areas. The connecting section includes a first tubular body fitted around the main body. The first tubular body is rotatable about the circular axis of the main body. The first tubular body is partially overlaid on the flutes. The geometric central axis of the profile of inner circumference of the first tubular body does not coincide with the circular axis of the main body. A user can selectively insert an L-shaped multiangular wrench into one of the flutes and the first tubular body. By means of rotating the first tubular body, the inner circumference of the first tubular body can tightly abut against the multiangular wrench for the user to more reliably and conveniently operate the wrench.

Claims

1. A connection compensating device of multiangular wrench socket, comprising:

a main body which is a cylindrical body, outer circumference of the main body between two ends thereof being formed with several radially arranged flutes which extend along a circular axis of the main body by a certain length, the flutes having different cross-sectional areas; and

a connecting section including a first tubular body fitted around the main body, the first tubular body being rotatable about the circular axis of the main body, the first tubular body being partially overlaid on the flutes, a geometric central axis of the profile of inner circumference of the first tubular body being not coincided with the circular axis of the main body.

2. The connection compensating device of multiangular wrench socket as claimed in claim 1, wherein the connecting section further includes a third and a fourth tubular bodies, the second and third tubular bodies being fixedly fitted on the main body and respectively positioned at two ends of the first tubular body, the two ends of the first tubular body being respectively pivotally fitted with one end of the second tubular body and one end of the third tubular body, whereby when rotating the first tubular body, the geometric central axis of the profile of the inner circumference of the first tubular body is rotated about the circular axis of the main body.

3. The connection compensating device of multiangular wrench socket as claimed in claim 2, wherein the flutes have openings at at least one end of the main body, a fourth tubular body being fixedly fitted on the end of the main body for collectively storing several multiangular wrenches.

4. The connection compensating device of multiangular wrench socket as claimed in claim 3, wherein each flute has a polygonal cross-section.

5. The connection compensating device of multiangular wrench socket as claimed in claim 4, wherein each flute has a pentagonal cross-section.

6. The connection compensating device of multiangular wrench socket as claimed in claim 3, wherein each flute has an arched cross-section.

7. The connection compensating device of multiangular wrench socket as claimed in claim 2, wherein each flute has a polygonal cross-section.

8. The connection compensating device of multiangular wrench socket as claimed in claim 7, wherein each flute has a pentagonal cross-section.

9. The connection compensating device of multiangular wrench socket as claimed in claim 2, wherein each flute has an arched cross-section.

10. The connection compensating device of multiangular wrench socket as claimed in claim 1, wherein the flutes have openings at at least one end of the main body, a fourth tubular body being fixedly fitted on the end of the main body for collectively storing several multiangular wrenches.

11. The connection compensating device of multiangular wrench socket as claimed in claim 10, wherein each flute has a polygonal cross-section.

12. The connection compensating device of multiangular wrench socket as claimed in claim 11, wherein each flute has a pentagonal cross-section.

13. The connection compensating device of multiangular wrench socket as claimed in claim 10, wherein each flute has an arched cross-section.

14. The connection compensating device of multiangular wrench socket as claimed in claim 1, wherein each flute has a polygonal cross-section.

15. The connection compensating device of multiangular wrench socket as claimed in claim 14, wherein each flute has a pentagonal cross-section.

16. The connection compensating device of multiangular wrench socket as claimed in claim 1, wherein each flute has an arched cross-section.
