The hand held electric planer capable of running forward automatically to complete planing consists of handle, motor, driving assembly, cutter shaft, cutter edge, bottom plate, chip discharging system, driving handle, driving wheel, drive regulating knob and other parts. It features that while partial motor power is used in driving cutter shaft, cutter edge and other parts for cutting, the other part of the motor power is fed to the forward running system for the cutter to run forward automatically. The driving handle serves as the forward running driving handle and the auxiliary handle, and when it is depressed down, the planer will run forward while cutting, with the forward driving force being regulated by turning the regulating knob. The hand held electric planer has reduced labor strength and raised operation efficiency.
