FIELD: process engineering.SUBSTANCE: invention relates to mechanised tool. Proposed tool comprises dust sucker and working mode selector. Said dust sucker incorporates suction part displacing between first position whereat said suction part covers at least the replaceable tool end and second position whereat said end is exposed. Mode selector can switch over between first mode whereat suction part stays in first position to displace between first and second position and second mode whereat suction part is shifted from first position to second position and locked thereat. Mode selector is located in the area of the part being gripped or nearby it. Said mode selector comprises locking element of suction part shifted from first position to second position and element to unlock said locking element. Second mode is selected by locking the suction part shifted from first position to second position at second position of locking element while first mode is selected by actuating unlocking element.EFFECT: friendly operation of mechanised tool.16 cl, 29 dwg |
