Bidirectional plunger hydraulic pump

The invention relates to the technical field of hydraulic pumps, in particular to a bidirectional plunger hydraulic pump. The pump comprises a pump body, a winding structure, a winding roll, a first pressing plate, a rotating shaft, a first sliding block, a first spring, a second spring, a second sliding block and a second pressing plate. The pump has the beneficial effects that a power line can be stored on the winding roll through the winding roll slidably connected to the bottom end of the pump body, one end of the winding roll is slidably connected with a first clamping plate, the first clamping plate is fixedly connected with the rotating shaft, one end of the rotating shaft is rotatably connected to the first sliding block, the elastic force of the first spring fixed connected to thefirst sliding block can drive the first clamping plate to slide towards the inner side of the winding roll, and the wound power line can be propped against and clamped, so that the situation that when the wound power line fa
