Abstract

The invention relates to a charging type screwdriver, which comprises a shell with a handle, wherein the handle is provided with a switch control device; a motor is arranged on the shell, and the shaft of the motor is used as a gear wheel mechanism of an input shaft; an output shaft of the gear wheel mechanism is connected with a connector; a screwdriver clamp is arranged on the part of the connector protruding out the shell; and a charging device comprising a battery pack and a circuit board is also arranged in the shell. Through the technical scheme of the invention, the screwdriver can be applied to the place without the power supply or where the power supply cannot be touched, and the fastening operation of a screw or stop of the losing operation of the screw can be automatically realized.

Description

technical field [0001] The invention belongs to the field of electric tools, in particular to an electric screwdriver. Background technique [0002] At present, the existing electric screwdrivers have the following problems. When using an electric screwdriver to fasten the screw, if the operator cannot lift the screwdriver in time, the tightening force on the screw will be too large, which will cause damage to the screw or when the screw is screwed, When the screw has been loosened, if the operator does not lift the screwdriver in time, the screwdriver is still turning, resulting in waste. [0003] In order to improve the defects of electric screwdrivers, the prior art proposes to adopt multi-speed shifting to realize different demands on screws. However, this technical solution only changes the power output of the screwdriver, and does not really solve the above-mentioned problems. Contents of the invention [0004] The purpose of the present invention is to provide an ...
