<p>Motorized tool (1) for extruding or sucking in semi-dense materials, such as sealants and similar substances, comprising a body in pistol form (2) containing a screw and nut system (3, 4) driven by means of a reversible electric motor (7) to move a piston (13). The electric motor (7) is controlled by a trigger switch (15) connected to an electronic variator (17) for controlling the motor (7) rotation speed and an adjustable stop device (18) to select the length of the backward stroke of the trigger switch (15) and therefore the rotation speed of the motor (7). Furthermore, a switch for selecting the rotation direction of the motor (7), consisting of the button (24) of a microswitch (23), is located in front of the trigger (15). <IMAGE></p> |
