Description

Hand tool sleeve structure

The invention relates to the structure of the hand tool sleeve portion, in particular to a hand tool sleeve portion which is provided with a protruding portion and a receiving portion 14 and is annularly arranged at intervals so that the sleeve portion can fit the hexagon. Two kinds of screwing parts of the screwing piece and the six-toothed screwing piece.

As is known in the prior art, the conventional hand tool arranging structure, such as U.S. Patent No. 4,512,220, is based on the structure of the body 10 having a ferrule 11 at one end, and the ferrule 11 is a hexagonal groove. The fitting portion 11 is a screwing member for fitting six side faces. Referring to the third figure, the fitting portion 11 includes a first curved surface 20, a second curved surface 21, and a third portion. The curved surface 30, the first curved surface 20, the second curved surface 21, and the third curved surface 30 are each provided with six and are arranged in an annular staggered manner, and each of the first curved surfaces 20 has two sides. Each of the first curved surface 21 and the second curved surface 21 is formed in a convex shape, and the third curved surface 30 is concavely shaped, and the third arc is formed. The opening angle of the surface 40 is not more than 34 degrees, and each of the first curved surfaces 20 is abutted against each side of the screwing member, and the six angular ends of the screwing member are respectively located in the third curved surface 30.

But the lack of the patent structure lies in:

1. The sleeve portion 11 of the body 10 is provided with a first curved surface 20, a second curved surface 21 and a third curved surface 40, and the third curved surface 40 is opened at an angle of 34 degrees, but the third curved surface 30 is 30. The depth is shallower. As shown in the fifth figure, the sleeve portion 11 of the structure is only for the screwing of the six side surface screws. The joint portion 11 cannot rotate the screw of other shapes, and the expansion of the body 10 is insufficient.

2. The first curved surface 20 and the second curved surface 21 are linear, and the two are connected by a chamfer D, and the first curved surface 20 and the second curved surface 21 are convex. Therefore, the chamfer D is the most convex portion, and the chamfer D radius is limited to the first curved surface 20 and the second curved surface 21, and the radius of the chamfer D is unlikely to be too large when the screwing member is rotated. If there is a large tolerance between the fitting portion 11 and the screwing member, it must be at the chamfering point D at the top of the six sides between the screw members, and the twisting torque is chamfered by the small radius. D is subjected to, the chamfer D is small radius and cannot be subjected to a large torque. When the torque is applied, the chamfer D is easy to wear. After the chamfer D is worn, the sleeve 11 will be larger and the snail will be larger. There are more tolerances between the parts.

In view of the lack of the structure of the above-mentioned conventional patent case, the inventor has borrowed the experience of the relevant industry for many years, and finally has a product that is practical and can improve the drawbacks.

The present system of the conventional structure can only rotate the hexagonal screw joint. The hand tool sleeve part of the present invention is provided with a protruding portion and a receiving portion, so that the sleeve portion can be fitted with a hexagonal screwing. The piece and the six-toothed screw are rotated.

A hand tool sleeve portion structure includes: a sleeve portion at one end of the body, the sleeve portion includes a protrusion portion and a receiving portion; each of the protrusion portions includes a first curved surface And two second curved surfaces, the two second curved surfaces are disposed on two sides of the first curved surface, and are symmetric with respect to the first curved surface, and the first curved surface is tangent to the second curved surface, the first The radius of the arc surface is greater than the radius of the second arc surface; each of the accommodating portions is received by each of the protruding ends of the six-toothed screwing member, and each of the accommodating portions includes a first concave edge and two Second concave edge, the two first The two concave edges are disposed on two sides of the first concave edge and are symmetric with the first concave edge. The first concave edge is tangent to the second concave edge, and the radius of the first concave edge is greater than the radius of the second concave edge. The second concave edge is connected to the protruding portion; the protruding portion is provided with a first angle, and the first angle is not more than thirty degrees.

The six protruding portions of the fitting portion of the body are abutted against each side of the hexagonal screwing member, and the fitting portion is driven by the hexagonal screwing member, and each of the fitting portions is driven A receiving portion is received by each of the protruding ends of the six-toothed screwing member, and the second curved surface of the protruding portion is abutted against the protruding end, and the fitting portion can fit the six teeth The screw-shaped component can rotate the screw of the two shapes and is expandable when used. Basically, the body has the highest probability of rotating the hexagonal screwing member, and each of the protruding portions includes a first curved surface and two second curved surfaces, and the radius of the first curved surface is greater than the second arc. The radius of the surface, when rotated, is six first curved surface clips on each side of the hexagonal screw, the first curved surface has a maximum radius, and the first curved surface has a larger The first curved surface is also not easily worn when the torque is rotated and rotated.
