Description

Hand tool fitting structure

This invention is related to the structure of a hand tool's coupling part, and particularly refers to a kind of hand tool coupling part structure. When the main body rotates the screw joint clockwise, the first surface is the main rotation surface, and the first surface rotates the second surface. On one side, the first side has a large area to rotate the screw, and the first side is less likely to cause bite marks.

According to our previous knowledge, the conventional hand tool sleeve structure, such as the United States Patent No.: US2006/0118918A1, Taiwan Patent Certificate No.: M270886, patent title: Socket to prevent nut head damage, please refer to the publication No. As shown in Figures 5 and 7, when the sleeve 20 is fitted with the nut head 40, the oblique protrusions 24 are locked at the center of each side of the nut head 40 to drive the nut head 40 to rotate. .

However, the shortcomings of this conventional hand tool joint structure are:

1. The latching oblique protrusions 24 bite the hexagonal surface, but the latching oblique protrusions 24 are in the shape of sharp angles. The latching oblique protrusions 24 easily cause the hexagonal surface to be affected by the force when rotating. It catches the sharp corner of the oblique protrusion 24 and causes bite marks.

2. The six engaging oblique protrusions 24 are in the shape of sharp angles. The structure of the engaging oblique protrusions 24 has only six lines interlocking with the six sides. The engaging oblique protrusions 24 are connected with the screw fitting. The rotational torque system between them is relatively insufficient.

In view of the above-mentioned shortcomings of the conventional hand tool coupling structure, the creators of the present invention have used many years of manufacturing experience in the industry to finally come up with a product with a hand tool coupling structure that can solve the conventional shortcomings.

In the conventional hand tool joint structure, the catch touches the sharp corner of the oblique protrusion and causes bite marks. In the hand tool coupling structure of this invention, when the main body rotates the screw fitting clockwise, the first surface is the main rotating surface, and the first surface rotates the first side surface. The face has a large area for turning the screw, and the first face is structurally less likely to cause bite marks.

The invention relates to a hand tool fitting structure, which includes: a system including a first side, a second side, a third side and a fourth side; the first side is provided with a first surface and a first groove, the first vertical line will pass through the first surface, 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 passes through the second surface; the fourth side is provided with a fourth groove, 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; the third side A fifth groove is provided at the connection between the side and the fourth side.

When the body rotates the screw joint clockwise, the first surface is the main rotating surface, and the first side rotates the first side surface. The first surface has a large area to rotate the screw joint. , the first surface is structurally unlikely to cause rotational bite marks on the first edge surface. The first groove, the second groove, the third groove and the fifth groove are aligned with the first sharp corner, In order to avoid wearing the first sharp corners, the main body rotates the screw component without causing bite marks on the six first side surfaces and wear to the six first sharp corners, thus having a protective effect. When the body rotates the screw member counterclockwise, the first surface, the second surface, the first intersection point and the fourth side can abut against the four first side surfaces of the screw member. The first side and the second side have different structures and perform respective functions.

In order to enable Jun Bureau members and people familiar with this art to fully understand the effect of this creation, the structure and composition of this creation are explained below with the help of diagrams and drawing numbers. However, the following is only used to explain the implementation of this creation. For example, there is no intention to impose any formal restrictions on this creation.
