Description

Hand tool structure

The present invention provides a hand tool structure, in particular a hand tool structure with a rod body having a hollow structure.

Hand tools have become an indispensable tool in industrial development. They are frequently used not only by professional technicians but also by ordinary users in daily life. There are many types of hand tools known, such as socket wrenches and screwdrivers, most of which are forged from metal materials to enhance the durability of hand tools. However, when such metal tools are used for a long time, their weight will cause users to have difficulty in operation, muscle soreness and joint discomfort.

To this end, plastic or rubber handles have emerged on the market to replace metal handles in order to achieve the goal of lightweighting hand tools. However, plastic or rubber handles still have the disadvantage of being easily aged and deteriorated.

The head is disposed at the first end of the rod, and the head is used to set a sleeve or a screw element. The grip is disposed at the second end of the rod. The head is integrally connected to the rod.

According to the hand tool structure of the aforementioned embodiment, the thickness of the supporting sheet can be 1 mm to 2 mm.

According to the hand tool structure of the aforementioned embodiment, the rod may further include a connecting structure, which is disposed at the second end and connected to the gripping member.

According to the hand tool structure of the aforementioned embodiment, the connecting structure may be in the shape of a hollow cylinder.
