The portable operating apparatus with interchangeable heads comprises: a) a basic unit including, inside a body (1) provided with a handle (2),: - a motor (3), - a hydraulic pump (7) driven by said motor (3), - a cylinder-piston system (18, 19) connected to said pump (7) through at least a duct (14, 29) for unidirectional feeding of the fluid, the rod (20) of the piston (19) coming out from the body, - connection flange (4) for an operating head (43, 46, 51, 56, 63, 68), said flange encircling the passage opening of said rod (20), - a tank (5) for feeding the fluid to the pump (7), - at least a duct (30) directly connecting said cylinder (18) to said tank (5), provided with a valve (31) actuable from outside, b) a plurality of operating heads (43, 46, 51, 56, 63, 68), each of them provided with a flange (42) engageable with said connection flange (4) of the basic unit, and c) means (40) for quickly binding said flanges (4, 42), coupled in facing conditions, so that the displacement of the piston rod (20) of the basic unit causes actuating of the operating head (43, 46, 51, 56, 63, 68). |
