[0036] Among them, a push ring 30 is provided at one end of the driven push rod 18, and the inner wall of the push ring 30 is rotatably connected to the outer wall of the second parallel frame 303. A return hose 31 is fixedly connected between the active input port 23 and the driven output port 28, and an output hose 32 is fixedly connected between the active output port 24 and the driven input port 29.

[0037] Among them, the end of the active push rod 14 away from the active hydraulic cylinder 13 is fixedly connected to the inner top wall of the lower pressing frame 7 to facilitate the conversion of the pressure of pressing down the pressing frame 8 into the pressure of hydraulic transmission.

[0038] Among them, an extension column 9 is integrally connected to the outer wall of the lower pressing frame 7. Pressing holes 10 are respectively formed through both sides of the pressing frame 8, and the inner wall of the pressing hole 10 is slidably connected to the outer wall of the extension column 9 to facilitate the conversion of the downward pressing and upward prying movements of the pressing frame 8 into the linear lifting movement of the lower pressing frame 7.

[0039] Working principle: When in use, insert the support fork 1 around the barrel opening so that the inclined cut 404 is aligned with the gap between the barrel opening and the barrel lid. Twist the torsion wheel 406, and the torsion wheel 406 drives the worm 405 to rotate. The worm 405 uses the thread to push the turbine 402 to rotate. When the turbine 402 rotates, it drives the engaging rod 403 and the inclined cut 404 to contract and press, and uses the inclined cut 404 to squeeze the gap to engage the engaging rod 403 on the edge of the barrel lid. At the same time, the barrel lid is squeezed upward and has a certain looseness. The thread on the surface of the worm and the inclined surface of the inclined cut 404 provide labor saving. Then press down the pressing frame 8. The pressing frame 8 rotates around the connecting frame 5. At the same time, when the pressing frame 8 is pressed down, it squeezes the extension column 9 through the pressing hole 10, thereby squeezing the lower pressing frame 7 to descend. When the lower pressing frame 7 descends, it drives the active push rod 14 to descend. When the active push rod 14 descends, it pushes the internal hydraulic oil to enter the driven input port 29 from the active output port 24 through the output hose 32, and then enters the driven hydraulic cylinder 17 to push the driven push rod 18 to extend. At the same time, when the driven push rod 18 extends, it will squeeze the hydraulic oil on the other side to enter the active input port 23 from the driven output port 28 through the return hose 31, so as to enter the other side of the active hydraulic cylinder 13 for replenishment. Since the hydraulic force receiving area of the active push rod 14 is smaller than the force receiving area of the driven push rod 18, the torque is amplified. When the driven push rod 18 extends, it will push the second parallel frame 303 to pry upward. The second parallel frame 303 drives the connecting rod 304 to rise through the parallelogram mechanism formed by the mounting block 301, the first parallel frame 302 and the connecting rod 304, thereby driving the fixed frame 401 to rise. When the fixed frame 401 rises, it will push the engaging rod 403 to rise, and the engaging rod 403 pushes the barrel lid to rise and open.
