Background

A screwdriver is a tool used to turn a screw to force it into place, usually having a thin wedge-shaped head that can be inserted into a slot or recess in the head of the screw, also known as a "screwdriver". The screwdriver is generally composed of a handle, a screwdriver rod and a screwdriver head, and is mainly divided into a straight line, a cross, a Chinese character 'mi', a square head, a hexagon and the like according to the shape of the screwdriver head. The method mainly comprises the following steps: 1. the common screwdriver: a screwdriver with the head and the handle being connected together. 2. The combined screwdriver: a screwdriver with a screwdriver head and a handle separated; when in use, different screwdriver heads can be replaced according to the requirements.

At present, with the continuous development of science and technology and the continuous update of products, the use scene of the screwdriver is continuously changed, and the screwdriver used by people is developed towards the trend of more portability and multiple functions.

The existing screwdriver is relatively fixed in length, is limited in the actual use process, and is inconvenient to use due to the fact that the screwdriver is too long or too short, so that the applicability of the screwdriver is reduced. If the cutter bar is too long, the screwdriver cannot completely enter narrow occasions, and the screwdriver is troublesome to use, and if the cutter bar is too short, the screwdriver head cannot reach the screwdriver when screws arranged in deeper holes or screws far away from a hand station need to be rotated. The existing screwdriver is inconvenient in length adjustment, and is inconvenient and complex in actual operation due to the fact that the limitation of the length of the screwdriver causes great force for screwing or unscrewing the screw nail.
