<p>A reciprocating hydraulic system includes a hydraulic output device (10) and a hydraulic input device (20). The hydraulic output device (10) comprises a hydraulic cylinder (11) with an output shaft (12). The hydraulic input device (20) comprises an input shaft (23) which is exposed to the surface of the former. The input shaft (23) can drive the hydraulic input device (20) to generate a hydraulic pressure and deliver the hydraulic pressure to the hydraulic cylinder (11) and the output shaft (12). The input shaft (23) of the hydraulic input device (20) is sleeved in a rotating seat (30) provided with a driving nut (40). An end of the driving nut (40) is fixed with the end of the input shaft (23) such that the input shaft (23) is driven to axially move when the driving nut (40) is rotated on the rotating seat (30), thereby driving the hydraulic input device (20) to generate the hydraulic pressure for driving the output shaft (12) to do work.</p> |
