The power camshaft 54 ​​is rotated by a tool such as an electric rotary, so that the cam on the surface of the power camshaft 54 ​​will squeeze the cam pressing sleeve 56, which will cause the connecting rod 55, the cam pressing sleeve 56 and the connecting block 57 to rise and fall, thereby driving the oiling piston 8 to slide in the inner cavity of the oiling cylinder 10.

[0025] See also Fig. 9 The anti-falling component 2 includes a positioning sleeve 21, and the positioning sleeve 21 is fixedly connected to the bottom of the shell 4. The surface of the positioning sleeve 21 is threaded with a bolt 22, and the surface of the positioning sleeve 21 is fixedly connected with a fixing ring 23. One end of the bolt 22 is mutually engaged with the thread groove. In this way, when the 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 telescopic cylinder shell 16 to prevent slipping and provide safety protection.

[0026] See also Fig.10 The mounting assembly 3 includes a sliding ring 31, and the sliding ring 31 is slidably sleeved on the surface of the housing 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 housing 4 before use, and is 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 housing 4, and then the lifting platform 33 is rotated on 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. When in use, when a vehicle rescue is required, first slide the sliding ring 31 to make the sliding ring 31 slide on the surface of the housing 4 and lock it through the lifting slot. After determining the position, move the quick-fix handle 32 to lock the quick-fix handle 32, and then rotate the lifting platform 33 to make it horizontal. Then, place the device on the ground through the base 1, and at the same time, the universal joint 15 can be used to rotate in the lower pressure cover 19, so that the device can be tilted horizontally by 20 degrees, 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. When the hydraulic pump is used, the stop valve 17 is closed, so that the hydraulic oil in the inner cavity of the oil guide pipe 13 can enter the inner cavity of the telescopic cylinder shell 16. The power cam shaft 54 ​​is rotated in the bearing 53 and the cover body 51 by a tool such as an electric rotary, so that the cam on the surface of the power cam shaft 54 ​​squeezes the cam sleeve 56, so that the cam sleeve 56 rises and falls in the guide groove 59, which drives the connecting rod 55 and the connecting block 57 to rise and fall in the inner cavity of the cover body 51, and also drives the pumping piston 8 to enter the inner cavity of the pumping cylinder 10. The oil pumping piston 8 first slides downward in the oil pumping cylinder 10 to realize positive pressure. The positive pressure generated will cause the oil inlet valve 72 and the oil outlet valve 73 to open and close alternately, so that the hydraulic oil in the inner cavity of the oil bag 11 first enters the inner cavity of the oil pumping cylinder 10 through the oil inlet valve 72, then flows into the oil guide pipe 13 through the oil outlet valve 73, and finally stays in the inner cavity of the telescopic cylinder shell 16. Then, the oil pumping piston 8 slides downward and then slides upward to release the negative pressure. At this time, the oil inlet valve 72 and the oil outlet valve 73 will automatically close. Close, and finally slide the oiling piston 8 repeatedly, so that the hydraulic oil in the inner cavity of the oil bag 11 enters the inner cavity at the bottom of the telescopic oil cylinder shell 16 in turn, and the oil guide pipe 13 is pushed to slide upward in the inner cavity of the cylinder core shaft 12 when the bottom volume increases, and it is against the inner cavity of the valve assembly 7. Because the valve assembly 7, the reciprocating structure 5 and the outer shell 4 are all fixedly connected, the outer shell 4 is driven to slide upward on the telescopic oil cylinder shell 16 to support the object to be supported, and then the bolt 22 is turned to make one end of the bolt 22 clamped on the telescopic oil cylinder shell 1 6 is provided with a threaded groove on the surface to limit the position and prevent it from slipping. Secondly, when the oil guide pipe 13 rises to a certain height, the stop valve 17 on the top of the stop piston assembly 14 will be squeezed on the upper pressure cover 18, thereby opening the stop valve 17, so that the hydraulic oil can no longer enter the inner cavity of the telescopic cylinder shell 16, and the hydraulic oil flows back to the oil bag 11 from the oil inlet valve 72 to form a cycle, and the oil guide pipe 13 will not be squeezed up by the hydraulic oil, and the shell 4 will not be driven to rise, thereby playing a role in stroke protection.

[0027] Secondly, a wrench can be inserted into the power camshaft 54 ​​to manually rotate the power camshaft 54, or it can be raised and lowered, thereby realizing different options of manual and auxiliary tools.

[0028] There is no need to use a hydraulic pump. First, turn the bolt 22 so that one end of the bolt 22 leaves the threaded groove on the surface of the telescopic cylinder housing 16, and then turn the pressure relief handle 6 so that the pressure relief handle 6 will drive the connecting needle 20 to move downward and against the pressure relief valve 71, so that the pressure relief valve 71 opens, thereby releasing the pressure. In this way, the hydraulic oil in the inner cavity of the telescopic cylinder housing 16 will flow upward along the oil guide pipe 13 and be discharged from the pressure relief valve 71 into the inner cavity of the oil bag 11.
