It is provided with 9 lifting slots, which can quickly adjust the appropriate lifting position. The inner cavity of the aluminum alloy shell 4 is slidably sleeved with a cylinder shell 16, the surface of the cylinder shell 16 is provided with a threaded groove, and the bottom of the aluminum alloy shell 4 is provided with an anti-slip component 2, the inner cavity of the cylinder shell 16 is provided with a telescopic cylinder 12, and the inner cavity of the telescopic cylinder 12 is slidably sleeved with an oil guide pipe 13 through a stop piston assembly 14, the oil bag 11 and the surface of the telescopic cylinder 12 are sealed and fitted with each other, wherein the inner cavity of the oil bag 11 is provided with high antifreeze hydraulic oil, which can be used in a low temperature environment of minus thirty degrees to avoid the influence of temperature changes on the hydraulic oil. It is located above the top of the oil cylinder housing 16. The top of the aluminum alloy housing 4 is fixedly connected to the top of the top cover 5. The top of the top cover 5 is rotatably connected to the handle rod 7 via a connecting rod 8. The handle rod 7 is lifted approximately 5.5mm each time it is pressed down. The mechanical design is more labor-saving and easy to operate. A pressure relief valve 6 is also provided on the top of the top cover 5. The pressure relief valve 6 passes through the top cover 5 and the inner cavity of the valve assembly 17 and is interconnected with the inner cavity of the oil sac 11. The other end of the pressure relief valve 6 is interconnected with the inner cavity of the bottom of the valve assembly 17. The top of the oil guide pipe 13 is located in the inner cavity of the bottom of the valve assembly 17. In other words, the pressure relief valve 6 is also interconnected with the oil guide pipe 13 for the purpose of hydraulic oil return.

[0029] The pressure relief valve 6 has the function of descending and stopping, which can make the product slowly descend to the warehouse or stop at the position you need, preventing the jack from suddenly falling and causing harm to the operator. A valve assembly 17 is provided at the bottom of the top cover 5, and the valve assembly 17 is located in the inner cavity of the aluminum alloy shell 4. The top of the oil guide pipe 13 is threadedly sleeved on the bottom of the valve assembly 17 and is interconnected with the inner cavity of the valve assembly 17. The inner cavity of the valve assembly 17 is respectively provided with an oiling valve 171, a connecting hole 172 and an oil inlet valve 173. The oil inlet valve 173 is located in the middle of the inner cavity of the valve assembly 17 and is respectively interconnected with the oiling valve 171 and the oil inlet valve 173. The bottom of the oiling valve 171 is connected to the oil pipe, and the bottom of the valve assembly 17 is fixedly connected to the oil bag 11. The top of the valve assembly 17 is fixedly sleeved with the oiling cylinder 10, and the inner cavity of the oiling cylinder 10 is slidably sleeved with the oiling valve 171. Plug 18, the top of the oiling piston 18 passes through the inner cavity of the top cover 5 and is rotatably connected to the handle rod 7, and the top of the base 1 is fixedly connected to the universal joint 15, and the top of the universal joint 15 is rotatably sleeved on the bottom of the cylinder shell 16. The base 1 can be adaptively adjusted through the universal joint 15 to achieve a horizontal frequency tilt of 20 degrees, which can easily cope with complex terrain during use. The surface of the aluminum alloy shell 4 is provided with a mounting component 3, and the upper end of the aluminum alloy shell 4 is fixedly sleeved with a rubber protective sleeve 9, wherein the surface of the rubber protective sleeve 9 is provided with an opening, which is used to clamp the handle rod 7 to fix the handle rod 7, and the rubber protective sleeve 9 prevents the downward pressing of the operating rod from colliding with the rod body and causing wear, and plays a protective role when the jack falls sideways.

[0030] See also Figure 7 The anti-slip component 2 includes a sleeve 21, and the sleeve 21 is fixedly connected to the bottom of the aluminum alloy shell 4. The surface of the sleeve 21 is threaded with a bolt 22, and the surface of the sleeve 21 is fixedly connected with a lifting ring 23. One end of the bolt 22 is engaged with the thread groove. In this way, when the aluminum alloy shell 4 is raised, the bolt 22 is rotated so that one end of the bolt 22 is stuck in the thread groove of the cylinder shell 16 to prevent slipping.

[0031] See also Figure 8 The mounting assembly 3 includes a sliding ring 31, and the sliding ring 31 is slidably sleeved on the surface of the aluminum alloy shell 4. The inner cavity of the sliding ring 31 is rotatably sleeved with a lifting platform 33 through a quick-fix handle 32, and a lifting hole 34 is provided on the surface of the lifting platform 33. The sliding ring 31 can slide on the surface of the aluminum alloy shell 4 before use, and be positioned through the lifting slot to determine the lifting position. Then, the quick-fix handle 32 is pulled to fasten the sliding ring 31 to the aluminum alloy shell 4, and then the lifting platform 33 is rotated to the horizontal plane. After rotating to the horizontal plane, the lifting platform 33 will be resisted to form a limit. The lifting hole 34 provided in addition is used in conjunction with a chain to lift objects.

[0032] During use, when a vehicle rescue is required, first slide the sliding ring 31 so that the sliding ring 31 slides on the surface of the aluminum alloy housing 4 and is locked in place through the lifting slot. After determining the position, move the quick-fix handle 32 to lock the sliding ring 31, and then rotate the lifting platform 33 to make it horizontal. Then, place the device on the ground through the base 1. At the same time, the device can be tilted 20 degrees horizontally through the universal joint 15, which can easily cope with complex terrain during use. Then, the lifting platform 33 is placed on the bottom of the vehicle to be rescued or a chain is connected through the lifting hole 34 to tie the chain to the tire. Then, the handle rod 7 is removed from the rubber protective cover 9.

[0033] When the hydraulic jack is started to be used, the handle rod 7 moves upward through the connecting rod 8, thereby driving the oiling piston 18 to move downward in the inner cavity of the oiling cylinder 10. The pressure in the inner cavity of the oiling cylinder 10 is reduced, and the oiling valve 171 is opened. The hydraulic oil in the inner cavity of the oil bag 11 will enter the communicating hole 172 through the oiling pipe connected to the bottom of the oiling valve 171. As the handle rod 7 moves downward, the oiling piston 18 will increase the pressure in the inner cavity of the oiling cylinder 10. The pressure will push the hydraulic oil in the inner cavity of the communicating hole 172 to move downward, thereby pushing the oil inlet valve 173, so that the oil inlet valve 173 is opened, and the hydraulic fluid passes through The oil inlet valve 173 enters the oil guide pipe 13, and finally flows out to the bottom of the inner cavity of the telescopic cylinder 12 through the bottom of the oil guide pipe 13. When the volume of the bottom increases, the oil guide pipe 13 is pushed to slide upward in the inner cavity of the telescopic cylinder 12, thereby driving the aluminum alloy shell 4 to slide upward on the cylinder shell 16 to support the object to be supported. As the handle rod 7 drives the oiling piston 18 to be pressurized, the hydraulic oil continues to enter the inner cavity of the telescopic cylinder 12, and it can continue to rise to the required height. Then, the bolt 22 is turned so that one end of the bolt 22 is clamped in the threaded groove set on the surface of the cylinder shell 16 to limit it and prevent it from slipping.

[0034] There is no need to use a hydraulic jack. First, turn the bolt 22 so that one end of the bolt 22 leaves the threaded groove on the surface of the cylinder shell 16, then bend the pressure relief valve 6 to press the pressure relief valve 6 downward to open it, and manually press the top of the device to squeeze the oil guide pipe 13 inside the telescopic cylinder 12, so that the hydraulic oil in the inner cavity of the telescopic cylinder 12 enters the inner cavity of the oil guide pipe 13, wherein the top of the oil guide pipe 13 is connected to the pressure relief valve 6, so that the hydraulic oil will enter the pressure relief valve 6 and flow back to the oil bag 11 through the pressure relief valve 6.
