[0002] A hydraulic jack is a tool that uses the hydraulic principle to lift heavy objects. A hydraulic jack is usually composed of a hydraulic cylinder, a manual pump, a control valve and an oil pipe. When the manual pump injects hydraulic oil into the hydraulic cylinder, the piston in the hydraulic cylinder will be under pressure and move upward, thereby lifting the heavy object. Hydraulic jacks are widely used in automobile maintenance, construction, machinery manufacturing and other fields. They can be used for replacing car tires, lifting buildings, installing mechanical equipment and other tasks. With the continuous advancement of science and technology, the performance and safety of hydraulic jacks are also constantly improving. A support device is required when using a hydraulic jack for work.

[0003] When the existing hydraulic jack is used directly, when the bottom of the work site is uneven or has a certain inclination, the support point of the jack will be unstable, increasing the risk of the jack tipping over or losing balance. When the jack is used on an inclined ground, the telescopic rod of the jack will be subjected to an inclined force instead of a vertical force, which will increase the wear of the telescopic rod and even cause it to bend or be damaged, affecting its normal operation.
