When the hydraulic oil pumped out by the oil outlet pipe 16 is output outward through the output interface 15, rotating the adjusting rod 20 at the top of the adjusting seat 19 can drive the valve core 24 to move up and down inside the adjusting seat 19. By adjusting the flow area inside the port 23, the flow rate is reduced, and the output pressure of the assembly can be quickly adjusted. At the same time, when the hydraulic assembly is in use, a flip-open and closable top cover 3 is set on the top of the oil tank 1. The top cover 3 can be used to provide auxiliary outer cover and anti-collision protection for the top components of the assembly. Furthermore, when the hydraulic assembly is installed and used, the exhaust fan 10 can be started to draw outside air into the top cover 3 after it has been filtered and dust-removed by the filter screen 26 in the side frame 5. Then, the exhaust fan 10 draws it outward. By increasing the air flow rate outside the top drive component, heat is carried away, the temperature outside the drive component is reduced, and auxiliary heat dissipation is provided for the hydraulic assembly drive component.
