Abstract

The invention relates to a universal serial bus (USB) pen type electric screwdriver. The USB pen type electric screwdriver comprises an outer shell, an installation housing arranged in the shell, a screwdriver blade, a battery component, a transmission device and an illumination device. The installation housing is formed by fastening a pair of half housing parts together. The transmission device comprises a gear motor arranged in the installation housing, a transmission shaft sleeve which is in transmission connection with a spindle of the gear motor and a bearing arranged on the outer side of the transmission shaft sleeve in a sleeving mode. The screwdriver blade is in transmission connection with the transmission shaft sleeve. A printed circuit board (PCB) is further arranged in the installation housing. A socket which is electrically connected with the PCB is arranged at the top of the installation housing. The gear motor and the PCB are mutually and electrically connected through a bilateral switch. The USB pen type electric screwdriver is reasonable in structure and easy and convenient to operate and is provided with the illumination device, so that the work efficiency is improved.

Description

Technical field [0001] The invention relates to the field of screwdrivers, in particular to a USB pen-type electric screwdriver. Background technique [0002] 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 the slot or notch of the screw head. The screwdriver is used to pry the paint cover by leveraging the working principle. The greater 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. The working principle of the wheel axle is used when the screwdriver is used to screw the screw. The larger the wheel, the more labor-saving, so the use of a thick screwdriver is more labor-saving than the use of a thin screwdriver. At present, electric screwdrivers have been widely used. However, the current electric screwdrivers are complex in structure, large in size, inconvenient for small screws, complicated in...
