Portable electric tool equipped with a device enabling the relative position of two members of said tool at least one of which can move to be determined
Portable electric tool, particularly electric or electronic secateurs, comprising a body (1) designed to act as a handgrip and at one of the ends of which there is mounted a moving active member (2) the movements of which are brought about by an actuator (8), characterized in that the moving part of the actuator (8) is equipped with an oriented magnetization magnet (13) that can be moved past a magneto-resistive sensor (14) fixed to a fixed element (1c) of the body, and in that the trigger (6) is equipped with an oriented magnetization magnet (15) that can be moved past a magneto-resistive sensor (16) fixed to a fixed element (1a) of the body, the said portable electric tool further comprising an electronic board for analysing the information emitted by each magneto-resistive sensor (14, 16) according to the inclination of the magnetic field lines presented to it, in order to control the operation of the actuator (8) so as to position the moving part (2) accurately according to the position of the control device (6).
