Abstract
A combination of electric tools includes a first electric tool and a second electric tool respectively having an independent power supply. The second electric tool starts working automatically responding to the startup of the first electric tool. Thereby the second electric tool starts automatically after the first electric tool is started to operate by a user without an extra operation of the user, which is convenient to the user.
