Embodiment Construction

[0036] The invention provides a turning tool with a set of holes, so that the turning tool can be socketed and screwed. The turning tool that can apply the sleeve hole 20 of the present invention can be figure 2 sleeve 22 as shown; or image 3 Torx wrench 24 as shown, or as Figure 4 The ratchet wrench 26 etc. shown, in other words, the invention can be implemented in any wrenching tool capable of manipulating screws.

[0037] Figure 5 It is an end view of the sleeve hole 20 of a preferred embodiment of the present invention. The set of holes 20 is basically formed by two polygonal holes with the same configuration but different sizes, such as regular polygons of triangle, quadrangle or pentagon. In this embodiment, a regular hexagonal hole is taken as an example. The two hexagonal holes are arranged in a concentric manner, and have an angular difference, that is, the six inner corners 30 of the first hexagonal hole are staggered with the six inner corners 40 of the seco...

Abstract

The invention provides a turning tool used for turning boltings, which is provided with a polygonal trepan boring; and the trepan boring is internally provided with a first regular polygonal hole and a second regular polygonal hole which have the same structure, different sizes and angular difference, are arranged concentrically, and form two socketed positions for being sheathed with the boltings. In the invention, a first small interior angle is arranged at one side of each interior angle of the first polygonal hole to lead the first interior angles to form another one socketed position, so as to sheathe an other-sized bolting. The turning tool of the invention has the beneficial effects of capability of being suitable for the multi-sized boltings, capabilities of reducing the production quality and the preparation processes of the tools with different sizes by manufacturers and achieving the environmental protection requirement of saving resources, and capabilities of reducing the purchase quantity of the tools and the expenses for the users, reducing the carrying quantity and the transportation expenses of the tools and providing convenience.

Description

technical field [0001] The invention relates to a turning tool, in particular to a screw turning tool with strong applicability. Background technique [0002] The sleeve is a commonly used tool when turning the screw. The sleeve is mainly provided with a polygonal sleeve hole, so as to socket and rotate the screw. [0003] Existing a kind of sleeve 10 such as figure 1 As shown, its sleeve hole 12 is made of two hexagonal holes, and the two hexagonal holes are concentrically arranged so that the sleeve hole 12 has twelve inner angles. The first hexagonal hole is formed by six inner corners 14 and the second hexagonal hole is formed by the other six inner corners 16 . The first hexagonal hole formed by the first set of inner angles 14 can be made into a larger size, and a screw can be socketed, while the second hexagonal hole formed by the second set of inner angles 16 can be made smaller size to operate smaller screws. Thereby, the sleeve 10 can use two sizes of screws. ...
