Description

Technical Field

[0001] The utility model relates to the technical field of screwdrivers, in particular to an anti-falling screwdriver. Background Art

[0002] A screwdriver is a commonly used hand tool. The basic principle is to use the mechanical principle of the spiral to transfer the rotating force to the screw through the lever to achieve the tightening or loosening operation. A screwdriver usually consists of two parts: the handle and the bit. The handle is the hand-held part, usually in the shape of a straight rod, which is easy to hold and turn. The bit is one end of the handle, usually a metal head ground into a specific shape. According to the shape and purpose of the bit, it can be divided into many types such as flat head screwdriver, cross screwdriver, hexagonal screwdriver, etc.

[0003] With the rapid development of science and technology, industrial, mining, civil, and household appliances that are lightweight, small in footprint, and highly intelligent have sprung up like mushrooms after a rain. Due to the small size of the equipment, the maintenance space is limited. When disassembling and installing a certain part with a screwdriver, it is impossible to hold the screw with one hand and turn the screwdriver with the other hand, which prolongs the maintenance time and increases the labor intensity of the operators. Sometimes, the equipment must be disassembled into the smallest unit to complete the work. There are indeed screwdrivers with magnetic blades on the market, but they lose their proper performance after being demagnetized for a certain period of daily use, and cannot complete the disassembly and assembly work.
