Description

Hand tool sleeve structure

The present invention is related to a hand tool sleeve joint structure, in particular to a hand tool sleeve joint structure, in which when the main body rotates the screw part clockwise, the first surface is the main rotating surface, that is, the first rotating side surface, and the first surface has a large area to rotate the screw part, and the first surface is less likely to cause bite marks.

According to what we know before, the structure of the hand tool sleeve is as shown in the US patent case number: US2006/0118918A1, Taiwan patent certificate number: M270886, patent name: sleeve to prevent nut head from being damaged. Please refer to the fifth and seventh figures of the public notice. When the sleeve 20 and the nut head 40 are sleeved, the locking inclined protrusion 24 is locked in the center of each side of the nut head 40 to drive the nut head 40 to rotate.

However, the defects of the joint structure of the hand tool used in this practice are:

1. The latching bevel 24 bites into the hexagonal surface, but the latching bevel 24 is sharp-angled. The latching bevel 24 can easily cause the hexagonal surface to be bitten by the sharp angle of the latching bevel 24 when rotating.

2. The six oblique projections 24 are sharp-angled. The structure of the oblique projections 24 only has six lines that are engaged with the six side surfaces. The rotational torque between the oblique projections 24 and the screw-on component is relatively insufficient.

In view of the above-mentioned shortcomings of the conventional hand tool sleeve joint structure, the inventor, with many years of manufacturing experience in the industry, finally came up with a product with a hand tool sleeve joint structure that can solve the conventional shortcomings.

In the hand tool sleeve structure, the card hits the sharp corner of the oblique projection and causes bite marks. In the hand tool sleeve structure of the present invention, when the main body rotates the screw part clockwise, the first surface is the main rotating surface, that is, the first side surface is rotated. The first surface has a large area to rotate the screw part, and the first surface is less likely to cause bite marks in terms of structure.

The present invention relates to a hand tool sleeve structure, which includes: a body including a first side, a second side, a third side and a fourth side; the first side is provided with a first surface and the first groove, the first vertical line will pass through the first surface, and the first groove is provided with a first arc surface and a second arc surface; the second side is provided with a second groove, a second surface and a third groove, the second groove is located on the left side of the first vertical line, and the first vertical line will pass through the second surface; the fourth side is provided with a fourth groove, and the fourth groove is close to the third groove; a first angle is provided between the first side and the third side, and a second angle is provided between the second side and the fourth side; a fifth groove is provided at the connection between the third side and the fourth side.

When the main body rotates the screw-on component clockwise, the first surface is the main rotating surface, and the first surface rotates the first side surface. The first surface has a large area to rotate the screw-on component, and the first surface is structurally unlikely to cause rotation bite marks on the first side surface. The first groove, the second groove, the third groove, and the fifth groove are aligned with the first sharp corner to avoid wearing the first sharp corner. When the main body rotates the screw-on component, it will not cause bite marks on the six first side surfaces and wear the six first sharp corners, which has a protective effect. When the main body rotates the screw-on component counterclockwise, the first surface, the second surface, the first intersection, and the fourth side can press against the four first side surfaces of the screw-on component. The first side and the second side have different structures and have the function of performing their respective functions.

In order to enable the members of the Jun Bureau and those familiar with this technology to fully understand the effects of the present invention, the structure and composition of the present invention are explained below with diagrams and figure numbers. However, the following is only used to explain the implementation examples of the present invention and is not intended to limit the present invention in any form.
