Description

Sleeve structure

The creation system is related to a sleeve structure. When the rotation is performed, the second vertical line of the first screw member and the first vertical line of the first sleeve portion of the first body may coincide. Therefore, the first fitting portion must be rotated at the middle of each side of the first screwing member, and the first fitting portion is unlikely to wear to the corner end of the first screwing member.

As is known to us, the conventional sleeve structure, as shown in the tenth and eleventh figures, the second body 30 is a Phillips wrench structure, of course, the second body 30 can also be a ratchet or sleeve structure. The second body 30 is provided with a second sleeve portion, and the second body 30 is provided with a third end and a fourth end. The third end and the fourth end are separated from each other. The second end portion and the fourth end portion, the second sleeve portion includes a plurality of third driving portions 32 and a plurality of third receiving portions 33, that is, the third driving portion 32 and the third receiving portion 33 is also arranged through the third end and the fourth end and is six and arranged in a spaced annular shape.

However, the missing structure of the conventional sleeve is that, as shown in the tenth and eleventh drawings, the second sleeve portion of the second body 30 is engaged with the first screw member 20 The second vertical line 34 is formed between the second vertical line 21 of the first screw member 20 and the second sleeve portion when the second angle 34 is too large. The portion 32 is close to the corner end of the first screw member 20, and may be rotated after a period of time The corner end of the first screwing member 20 is rounded, and the corner end of the first screwing member 20 is rounded to make it difficult to unscrew the first screwing member 20 from the screw hole. The screw member 20 is to be unscrewed in a broken manner.

In view of the lack of the above-mentioned conventional sleeve structure, the creator has been engaged in the manufacturing, production and design experience of related industries for many years, and finally has a product that can solve the drawbacks of the sleeve structure.

The first part of the structure of the hand tool of the conventional hand tool When the second sleeve portion of the second body is engaged with the first screwing member, it is loosely fitted, and after the rotation for a period of time, the corner end of the first screwing member may be rounded and caused trouble. When the sleeve structure of the present invention is rotated, the second vertical line of the first screw member and the first vertical line of the first sleeve portion of the first body may coincide, so The first set of joints must be rotated at the middle of each side of the first screw member, and the first sleeve portion is unlikely to wear to the corner end of the first screw member.

A sleeve structure comprising: a first The system is provided with a first sleeve portion, the first sleeve portion is in the shape of a hexagonal groove, the first sleeve portion includes a first end and a second end, and the first system is a sleeve structure; The first end portion includes a plurality of first driving portions and a plurality of first receiving portions, and the first driving portion and the first receiving portion are each six in number, the first driving portion The first accommodating portion includes a first convex arc surface, and the first accommodating portion includes a first concave curved surface, the first convex curved surface and the first accommodating portion The first concave arc surface is tangent; the first sleeve is at the second end The second driving portion includes a second convex arc surface, and the second receiving portion includes a second concave curved surface, the second convex curved surface system It is tangent to the second concave curved surface.

The second vertical line of the first screw member when rotating And the first vertical line of the first sleeve portion of the first body coincides with each other, so that each of the first driving portions must be rotated at the middle of each side of the first screw member, the first The driving portion is unlikely to be worn to the corner end of the first screwing member, and the first driving portion of the first body is provided with the first driving portion and the second driving portion, and is designed to be of a metric specification. In addition to the first screwing member that can be screwed into the metric, the first fitting portion can also rotate the first screw member of the inch size to have operational expandability.
