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 fits into a slot or notch in the screw head. A screwdriver works on the principle of a lever when used to pry a paint cover. The greater the distance from the power point to the fulcrum, the more labor-saving, so a long screwdriver is more labor-saving than a short screwdriver. A screwdriver makes use of the working principle of a wheel axle when it is used to turn a screw. The larger the wheel, the less effort it takes, so using a screwdriver with a thick handle saves more effort than screwing a screw with a screwdriver with a thin handle. At present, electric screwdrivers have been widely used. However, the current electric screwdrivers have complex structures and large volumes, which are inconvenient t...
