Description

Technical Field

[0001] The utility model relates to the technical field of screwdriver rods, in particular to a fast-folding screwdriver rod. Background Art

[0002] The screwdriver shank is the main part of the screwdriver, which is usually made of metal (such as chrome vanadium steel, stainless steel or carbon steel) and is used to transmit torque (rotational force) to the screw head to tighten or loosen the screw.

[0003] For example, a Chinese patent discloses a screwdriver, publication number: CN218984617U, which operates the blades to move closer or farther from each other through operating components and elastic parts, thereby driving the blade heads to move closer or farther from each other. When the blade heads move closer to each other, the height of the insertion part becomes larger, and it is in close contact with the slot or notch of the screw, so that the screw can be prevented from falling by tension and friction; when the blade heads move away from each other, the height of the insertion part becomes smaller, and it is separated from the slot or notch of the screw, which is convenient for detaching from the screw. The screwdriver is easy to operate with one hand, and can prevent the screw from falling or being lost, and prevent the screw from falling into the device, thereby preventing it from causing damage to the device. However, most existing screwdrivers are not easy to fold, and the screwdriver heads are mostly directly exposed to the outside. When used, some staff members will put the screwdriver in their pockets. When the staff members perform large-scale exercises such as climbing electric poles and running, the screwdriver heads placed in their pockets can easily injure people by mistake, and the safety is low.
