Hand tool rotation structure

The invention relates to the structure of the rotary part of the hand tool, and the structure of the rotary part of the hand tool is provided with a sleeve part, the sleeve part comprises a first driving part, a second driving part and a first receiving part. The second accommodating portion has a general swaying manner and a screwing member with a rounded corner.

As previously known by us, the conventional hand tool rotation part structure, such as Taiwan Patent Application No.: 089206331, patent name: sleeve structure improvement, the patent structure is: a sleeve structure improvement, the main features are: The hexagonal groove of the sleeve 20 is formed by a large convex arc surface 22 and a small concave curved surface 21, and a plurality of oblique teeth 23 and a plurality of reverse slopes are arranged on the large convex curved surface 22. The teeth 24, the helical teeth 23 and the reverse helical teeth 24 are staggered, and the large convex curved surface 22 forms a chamfered inclined surface 25.

However, the lack of the structure of the rotary tool of this hand tool is:

The large convex arc surface 22 is provided with a plurality of slanting teeth 23 and a reverse slanting teeth 24, and the sleeve 20 is engaged by the slanting teeth 23 and the reverse slanting teeth 24 on the large convex curved surface 22 when the rotating surface 22 is rotated. The helical peripheral surface 31 of the screw member 30 has a sharp angle, and the helical teeth 23 and the reverse helical teeth 24 facilitate the screwing member 30. The hexagonal peripheral surface 31 is caused to be bitten by the oblique tooth 23 or the reverse helical tooth 24 when it is rotated.

Another Taiwan patent application number: 105205070, certificate number: M528831, patent name: progressive wrench structure, the first end angle 23 and the second end angle 32 are pointed, the first end angle 23 and the first The two end angles 32, that is, the slanting teeth 23 and the reverse slanting teeth 24 of the same application number 089206331 are arranged in a staggered manner, so that the hexagonal circumferential surface of the screwing member is liable to cause bite marks and has the same defect.

Another U.S. patent case number: US2006/0117917A1, namely Taiwan Patent Certificate No.: M270886, patent name: a sleeve with a damaged nut head, please be accompanied by the fifth and seventh figures of the bulletin, when When the sleeve 20 is engaged with the nut head 40, the card abutment 24 of the sleeve hole 22 is locked at the center of each side of the nut head 40 to drive the nut head 40 to rotate, but The card abutment 24 is in the shape of a pointed corner, and the swivel torsion force of the card abutment 24 is insufficient and causes a bite of the nut head 40.

In view of the lack of the structure of the rotary part of the above-mentioned hand tool, the inventor has been engaged in the manufacturing experience of the related industry for many years, and finally has a product that can solve the drawbacks of the hand tool rotation part structure.

The spin of the custom is used to unscrew the snail with rounded corners. When the component is rotated, the side surface of the screwing member is bitten. Generally, the hand tool rotating part structure of the present invention is provided with a fitting portion, and the fitting portion includes a first driving portion and a second portion. The driving portion, the first accommodating portion and the second accommodating portion have both a general swaying manner and a screwing member having a rounded corner.

A hand tool swirling portion structure, the system comprising: The first system has a first driving part, a second driving part, a first receiving part and a second receiving part, the first driving part, the first receiving part, The second driving portion and the second receiving portion are arranged in a ring shape in sequence, and the first driving portion and the second driving portion are three and arranged in a ring shape, and the first driving portion and the second portion The first accommodating portion and the second accommodating portion are arranged in an annular shape, and the first accommodating portion and the second accommodating portion are disposed between the driving portions. Each department has three departments.

The system can be screwed clockwise and counterclockwise When the screwing member is opened and the screwing member is unscrewed counterclockwise, the three first acting portions are only for assisting the force application, and it is less likely to cause a bite on the side surface of the screwing member, and the screwing member is ground. When the fillet is rounded, the three first acting portions can engage the three sides of the screwing member to bite into the three side surfaces and rotate the screwing member at an organic rate, thus having a general rotation. The dynamic mode and the swirling effect of rotating the screw with rounded corners.
