Abstract
The invention discloses an electric chain saw. The electric chain saw comprises a front handle arranged at the front part of a machine shell and a rear handle arranged at the rear part of the machine shell. The rear handle is provided with a switch button. The front handle is provided with a micro switch which is connected with the switch button in series. When the switch button and the micro switch are started at the same time, the electric chain saw works. When any one of the switch button and the micro switch is in a closed state, the electric chain saw cannot be started. According to the electric chain saw, a front switch and rear switch linking structure is arranged on the electric chain saw for controlling the starting of the machine and improving the safety of an operator. A switch pulling rod of the handle in the front handle can be connected with the switch along two directions, so that the operability of machine under different environments is improved.
