Abstract
The present invention discloses a control system for the blade teeth superposition of a cutting tool, which comprises a housing 1 and double blades 6, 7, and at least one switch. A motor control circuit and a blade position detecting device are arranged in the housing, the motor control circuit detecting the position of the blades and controlling the blades to stop when the teeth are superimposed when the at least one switch is switched off. The blade position detecting device may comprise a Hall element 3 arranged in the housing and a magnet 4 provided on the blade. The control system and method for the blade teeth superposition of the cutting tool allows for an object to be cut to be disengaged from the tool. The superimposition of the blades also acts as a safety feature.
