The staff member can also rotate the third connecting rod (233), and drive the second rotating tube (232) to rotate through the third connecting rod (233), and drive another group of third connecting rods (233) to rotate through the second rotating tube (232), and drive the second connecting plate (234) to follow the movement through the rotation of the third connecting rod (233), and the movement of the second connecting plate (234) drives the first connecting rod (230) to move, and then indirectly drives the first rotating tube (220) to rotate through the first connecting rod (230), and then drives the hydraulic pump body (100) to perform hydraulic work through the rotation of the first rotating tube (220).
