electrical tools

Abstract

The invention discloses an electric tool, which has at least one screwdriver mode. The electric tool includes: a power supply; an output shaft that only rotates around the first axis in the screwdriver mode; a motor; an output setting component that is in the screwdriver mode It is for the user to set the maximum output torque of the output shaft; the output control component controls the maximum output torque of the output shaft according to the setting of the output setting component in the screwdriver mode; the output setting component includes: operating parts for the user to operate; The control signal device generates different control signals according to different settings of the operating parts by the user; the output control component includes: a control switch to control whether the power supply is powered by the motor; the controller has at least one torque control mode; in the torque control mode, The controller controls the control switch to power off the motor when the current of the motor reaches a current threshold corresponding to the control signal. The electric tool of the present invention has three modes of electric hammer, electric drill and screwdriver respectively.

Description

technical field [0001] The invention relates to an electric tool, in particular to a multifunctional electric tool which can be used as a screwdriver, an electric drill and an electric hammer. Background technique [0002] With the development of society, electric tools are used more and more widely, and people's performance requirements for electric tools are also getting higher and higher. As a kind of electric hammer, it usually has two modes: hammer-drill gear and drill gear. Autorotation movement, so that it can drill holes on hard substrates such as concrete; in the drill gear mode, the output shaft only works with autorotation movement, and it outputs at its maximum torque at this time, which cannot be adjusted by the user. But in some working conditions, the user may need to use a small torque to control the state of screwing in. At this time, because the ordinary electric hammer has no torque adjustment function, it can only be operated by the user's own feeling, w...

Problems solved by technology

As a kind of electric hammer, it usually has two modes: hammer-drill gear and drill gear. Autorotation movement, so that it is possible to drill holes on harder substrates such as concrete; in the drill gear mode, the output shaft only works with autorotation movement, at this time it outputs at its maximum torque, which cannot be adjusted by the user

But in some working conditions, the user may need to use a small torque to control the state of screwing in. At this time, because the ordinary electric hammer has no torque adjustment function, it can only be operated by the user's own feeling, which is very inconvenient.
