Electric screwdriver with rotary wire stripping device

Abstract

The invention discloses an electric screwdriver with a rotary wire stripping device. The electric screwdriver comprises a middle sleeve, a tool fixing part and a movable tool bit. A cylindric cavity coaxial with the middle sleeve is arranged in the middle sleeve. A through hole penetrating a sleeve body of the middle sleeve is formed in the middle of the middle sleeve. The axis of the through hole is perpendicular to and intersects with the axis of the cavity. The position of the through hole is located at a front end opening of the cavity. Two strip-shaped grooves are formed in the inner wall in the middle sleeve. The movable tool bit comprises a movable shaft and a shearing tool bit. The movable shaft is in threaded sleeve connection in the middle sleeve. The shearing tool bit is provided with a semicircular tool edge, the upper end and the lower end of the shearing tool bit penetrate the strip-shaped grooves, and the middle of the shearing tool bit is movably connected to the front end of the movable shaft. According to the electric screwdriver with the rotary wire stripping device, the wire stripping process of cables is effectively achieved, and the cables can be fast and effectively clipped; and the overall structure is simple, use is convenient, and high practicality is achieved.

Description

[0001] Technical field: [0002] The invention relates to an electric screwdriver with a rotary stripping device, and relates to the field of hardware cutters. [0003] Background technique: [0004] A screwdriver is a tool used to turn a screw to force it into place. It usually has a thin wedge-shaped head that can be inserted into a slot or notch in the screw head. There are mainly two types: a word and a cross. There are also hexagonal screwdrivers that are common, including inner hexagonal and outer hexagonal. When the screwdriver is used to pry the paint cover, the working principle of the lever is used. The larger the distance from the power point to the fulcrum, the more labor-saving, so the long screwdriver is more labor-saving than the short screwdriver. When screwing screws, the working principle of the wheel shaft is used. The larger the wheel, the more labor-saving it is. Therefore, it is more labor-saving to use a screwdriver with a thick handle than to use a screw...

AI Technical Summary

Problems solved by technology

There are also hexagonal screwdrivers that are common, including inner hexagonal and outer hexagonal. When the screwdriver is used to pry the paint cover, the working principle of the lever is used. The larger the distance from the power point to the fulcrum, the more labor-saving, so the long screwdriver is more labor-saving than the short screwdriver. When screwing screws, the working principle of the wheel shaft is used. The larger the wheel, the more labor-saving it is. Therefore, it is more labor-saving to use a screwdriver with a thick handle than to use a screwdriver with a thin handle. Some current electric screwdrivers also have a stripping function. , but in actual use, the stripping blade is placed outside the screwdriver body, which makes it easy to scratch the user during use, and the safety is low, and its actual use is inconvenient and the stripping efficiency is low
