The tool uses a bar (1) with a joint (2) on its top to hold part (3) with movement limitating means (4). In the annular hollow (5) a clamp (6) is foreseen which can be tightened by means of a wing nut. In the hollow (8) of part (7), a prosecution of part (3), an electrical motor (9) is positioned which is reached by the power mains (10) on terminals (11). In the space (12), the driving motor (13) transmits the motion by means of the gear pair (14) to the shaft (15) which lets the expanding clutch (16) turn within the bell (17) integral with the driving pinion (18). The tool can be brought upwards as high as wished by putting one or more components (22) in prosecution of bar (1). |
