Description

Technical Field

[0001] The utility model belongs to the technical field of hand tools, and in particular relates to a screw driver. Background Art

[0002] A screwdriver is a tool used to turn screws, sleeves, etc. to rotate them into place. It usually has a thin wedge-shaped head that can be inserted into the slot or notch of the screw or sleeve. By rotating the screwdriver, the screw or sleeve is rotated to the specified position. The handle and the bit of a traditional screwdriver are generally processed into a whole, and the bit cannot be replaced. In order to facilitate use and adapt to various types of screws and sleeves, many screwdrivers use one handle with several bits. When screws and sleeves of different specifications and models are to be turned, the corresponding bit model of the screw or sleeve can be replaced. However, the handle is generally cylindrical. During use, when the handle is turned to tighten or remove the screw or sleeve, the handle is easy to slip in the operator's hand. When the handle is small, the handle is not easy to turn, and it may not be tightened in place or the removal is too laborious, resulting in reduced work efficiency. Utility Model Content
