Description

Hand tool sleeve structure

The invention relates to the structure of the hand tool sleeve part, in particular to a hand tool sleeve part which is provided with a protruding portion and a receiving portion and is annularly arranged at intervals, so that the sleeve portion can be fitted with a star-shaped screw. Pieces and hexagonal screws.

As previously known by us, the conventional hand tool splicing structure, such as U.S. Patent No. 3,584, 667, is based on the eighth and third figures, and the body 10 is provided with a sleeve at one end. In the portion 65, the fitting portion 65 is in the form of a star-shaped groove, and the fitting portion 65 is for fitting a star-shaped screwing member, and the star-shaped fitting portion and the screwing member are a TORX-sized fitting portion and The screwing member, as shown in the third figure, is the principle of the TORX specification, and the fitting portion 65 includes a first curved surface 18 and a second curved surface 22, and the first curved surface 18 and the second curved surface Each of the first curved surface 18 and the second curved surface 22 is annularly staggered, and each of the first curved surface 18 has a second curved surface 22, The first curved surface 18 is tangential to the two second curved surfaces 22, and the first curved surface 18 has a concave curved surface, and the second curved surface 22 has a convex curved surface.

But the lack of the patent structure lies in:

1. The sleeve portion 65 of the body 10 is only provided with a first curved surface 18 and a second curved surface 22, and the sleeve portion 65 is for fitting a star-shaped screwing member, that is, the sleeve portion 65 of the eighth figure. Only the screw of the first figure can be fitted, that is, the TORX fitting can only fit the screw of the TORX, although as shown in the third figure, the six second curved faces 22 are tangent to one. On the hexagon, but the opposite side 26 of the hexagon cannot be a metric ruler. The sleeve portion 65 of the body 10 cannot fit the metric screw member. For example, when the sleeve portion 65 is of the E26 size, the opposite side 26 is 17.5 mm, so that the sleeve portion 65 should be nested with 17 mm. When the hexagonal metric screwing member is rotated, the rotation tolerance between the fitting portion 65 and the hexagonal metric screwing member is too large, that is, the body 10 of the eighth figure can only fit and rotate the first figure. The TORX screw fittings are slightly insufficient to use the expansion system.

2. If the fitting portion 65 of the body 10 is fitted with a hexagonal screwing member, the six angular ends of the screwing member are respectively received in the second curved surface 22, which is a theoretical principle. The fitting portion 65 of the body 10 and the hexagonal screwing member are loosely matched. For example, the fitting portion of the 19 is required to be between 19.06 and 19.36, and the screwing member of the 19 is a maximum of 18.97. Tolerance, when the sleeve portion 65 of the E26 is rotated by the 17MM hexagonal screw, the sleeve portion 65 of the E26 and the hexagonal screw member are angularly different due to the tolerance state, such that the sleeve portion 65 The hexagonal metric screwing member cannot be rotated, and the six corner ends of the hexagonal screwing member abut against the fitting portion 65 to wear the corner ends, and the fitting portion 65 is larger and the screwing member There are more tolerances between them.

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 conventional fitting part can only rotate a screw of a shape, and the rotation part is not expandable, and the fitting part of the hand tool fitting part of the invention is provided with a protruding part and a receiving part and a ring. The phases are spaced apart such that the sleeve portion can be fitted with a star-shaped screw member and a hexagonal screw member.
