[0028] Please also refer to Figs. 1 to 4The utility model provides a ball valve with labour saving operation handle device, including valve body assembly 1, drive assembly 7 is rotatably connected in valve body assembly 1, rotatable assembly 12 is rotatably connected in valve body assembly 1, hydraulic assembly 19 is fixed in valve body assembly 1, rotatable assembly 12 includes pivot 13, pivot 13 is directly fixedly connected with valve ball in the inside of support pipe 2, pivot 13 is rotatably connected in valve body assembly 1, pivot 13 is rotatably connected in protective shell 5, stud 14 is fixed in the inside of pivot 13, pivot 13 can move up and down by the rotation of stud 14, pivot 13 top is fixed with turntable 15, turntable 15 is equivalent to increasing the radius of pivot 13, that is equivalent to lengthening the length of rotating arm, turntable 15 one side is fixed with gear ring 16, pivot 13 one side is fixed with connecting rod 17, connecting rod 17 one side is fixed with guide ring 18, and guide ring 18 is slidably and sealingly connected in hydraulic groove 6.

[0029] Further, valve body assembly 1 includes support pipe 2, and the end of support pipe 2 is fixedly connected with a screw head 3. The screw head 3 is sleeved with a sealing gasket 4 on one side. The sealing gasket 4 plays a sealing role. The top of the support pipe 2 is fixedly connected with a protective shell 5. The inside of the protective shell 5 is provided with a hydraulic groove 6. The hydraulic groove 6 is filled with hydraulic oil.

[0030] Further, the drive assembly 7 includes a rotating rod 8, which plays a supporting and transitional connecting role. The rotating rod 8 is rotatably connected in the protective shell 5. The rotating rod 8 is fixedly connected with a gear 9 on one side. The gear 9 is engaged with the gear ring 16. The rotating rod 8 is fixedly connected with a rotating arm 10 on one side. The rotating arm 10 is equivalent to increasing the radius of the rotating rod 8, that is, equivalent to lengthening the length of the rotating arm.

[0031] Further, the hydraulic assembly 19 includes a bottom cylinder 20, which is fixed in the protective shell 5. The bottom cylinder 20 is provided with an oil inlet hole 21 at the bottom. The oil inlet hole 21 can make the hydraulic oil in the hydraulic groove 6 enter the bottom cylinder 20. The inside of the bottom cylinder 20 is slidably connected with a sliding cylinder 22. The sliding cylinder 22 plays a role in limiting the moving direction of the connecting plate 25 and changing the space in the bottom cylinder 20. Therefore, when the sliding cylinder 22 moves upwards, the hydraulic oil in the bottom cylinder 20 and the hydraulic groove 6 can be pumped, so that a negative pressure is formed in the hydraulic groove 6. Therefore, under the action of external air pressure, the guide ring 18 can be deeply inserted into the hydraulic groove 6.
