Socket tool

Abstract

This invention relates to a sleeve tool, comprising: a tubular component including a working end, a set of connecting ends, and a piercing groove. The working end includes a polygonal sleeve hole, and the set of connecting ends includes a shaft hole. The piercing groove pierces the working end at least radially and connects the sleeve hole and the shaft hole. The sleeve hole includes multiple hole edges and multiple vertices. The piercing groove includes two opposing groove edges, the radial extension lines of which intersect two adjacent hole edges respectively, and one of the vertices is located between the radial extension lines of the two groove edges.

Claims

1. A socket tool, comprising: A tubular component includes a working end, a set of connecting ends, and a through groove. The working end includes a polygonal sleeve hole, and the set of connecting ends includes a shaft hole. The through groove at least radially penetrates the working end and connects the sleeve hole and the shaft hole. The sleeve hole includes multiple hole edges and multiple vertices. The through groove includes two opposing groove edges, the radial extension lines of which intersect two adjacent hole edges, and a vertex is located between the radial extension lines of the two groove edges. The tubular component includes a first pipe fitting and a second pipe fitting, which are detachably inserted into each other. The first pipe fitting includes a large-diameter section and a small-diameter section, and the small-diameter section is detachably inserted into the second pipe fitting.

2. The sleeve tool as claimed in claim 1, wherein the width of the piercing groove is smaller than the diameter of the shaft hole.

3. The sleeve tool as claimed in claim 2, wherein, viewed along an axial direction of the tubular member, the shaft hole is part of a circle and includes a superior arc, the two groove edges being respectively connected to the two ends of the superior arc.

4. The sleeve tool as claimed in claim 1, wherein a apex of the sleeve hole and a radial extension of the center of the sleeve hole pass through the midpoint of the opening of the piercing groove.

5. The sleeve tool as claimed in claim 1, wherein each of the groove edges has at least one chamfer.

6. The sleeve tool as claimed in claim 3, wherein the sleeve hole is part of a regular hexagon; the major arc is greater than 200 degrees; a apex of the sleeve hole and a radial extension of the center of the sleeve hole pass through the midpoint of the opening of the piercing groove; each edge of the groove has at least one chamfer.

7. The sleeve tool as claimed in claim 1, wherein the inner surface of the second fitting includes at least one groove, and the outer peripheral surface of the small diameter section is provided with at least one retainer, the at least one retainer being releasably engaged in the at least one groove.

8. The sleeve tool as claimed in any one of claims 1 to 7, wherein the radial dimension of at least one of the groove edges is not less than the shortest distance from any point on each of the hole edges to the outer peripheral surface of the tubular member.
