[0002] In today's society, earthquakes, mining disasters, traffic accidents and other emergencies occur frequently, and people often talk about them with fear. Once a disaster suddenly strikes, people are often in a panic and at a loss. The rescue also consumes a lot of manpower and material resources, and takes a long time, which is very detrimental to the lives in danger.

[0003] It is critical to take necessary measures to rescue the lives of people trapped under heavy objects in the shortest possible time. The existing ordinary jacks have limited lifting height and poor flexibility. Due to the uneven ground and lack of effective support points, the jacks and other equipment cannot work effectively. In the specific rescue process, the space is often relatively small and the rescue equipment cannot be put in, which reduces the overall use effect. Existing rescue equipment such as shears, expanders, rescue pliers, and top supports are often complicated, inconvenient to carry and expensive.

Due to the uneven ground and lack of effective support points, the jacks and other equipment cannot work effectively. In the specific rescue process, the space is often relatively small and the rescue equipment cannot be placed in, which reduces the overall use effect. A hydraulic jack that can rotate in multiple directions can be designed, and a base adjustment device can be added. The connecting device can realize the multi-directional rotation of the lever body.

[0026] The additional details are

[0027] (1) The lever body can freely slide. The lever body can adjust the position of the fulcrum according to different distances and different loads. The front rod 4 of the lever body can slide freely on the connecting piece, and the jack 101 can be raised and lowered to adjust the height, so that lifting at different angles and different loads can be achieved.

[0028] (2) The 360° rotating connection device allows the lever to be pried at multiple angles without changing the fulcrum position. Since the lever can rotate freely, its practicality is greatly enhanced.

[0029] (3) The height-adjustable jack 101 can adjust the support point height while maintaining the original function of the jack 101; the height adjustment range is 358mm to 548mm.

[0030] (4) Stability Adjustment The stability of operation can be enhanced by adjusting the adjustment device of the base 1. The height adjustment of the base 1 bracket 103 stabilizes the lever force point, reduces the side effects of radial unbalanced force, and reaches the level of the base 1, which can meet the requirements of the device for stable operation at different angles and planes.

[0031] (5) Convenient and quick disassembly and easy to carry. The four components of this device can be disassembled, easy to carry, and easy to adjust during use.

[0032] When working, place the overall base 1 in a suitable position and install it through the mounting hole 107 on the balance mounting plate 106. Use the adjusting bolt sleeve 104 to adjust the overall height, and observe the mercury balance identification column 105 and the mercury balance identification plate 102 to observe the overall longitudinal and planar balance status. When rotating, the ring sleeve 305 uses the second guide sleeve 303 to make its second movable pin 302 rotate along the inside of the second fixed sleeve 304, which can achieve 360° rotation and all-round prying. The lever body can slide back and forth in the sleeve 6 to achieve prying of objects at different distances.

[0033] Through the above steps, the lever body can arbitrarily adjust the position of the fulcrum according to different distances and different loads. The connecting device can enable the lever body to achieve multi-angle prying without changing the position of the fulcrum. The jack 101 can adjust the support point height while maintaining the original function of the jack 101; by adjusting the adjustment device of the base 1, the stability of the operation can be enhanced, and disassembly and carrying are convenient.
