[0013] Preferably, the second slot on the lifting leg and the third slot on the supporting leg are fixedly connected via a second latch.

[0014] Compared with the prior art, the beneficial effects achieved by the utility model are:

[0015] The utility model places the hydraulic jack under the vehicle and moves it to the required position, so that the disc at the bottom of the upper connecting assembly contacts the top of the hydraulic jack, and the hydraulic jack is lifted upward to lift the top block and contact the top vehicle point to lift it to the required height, then the two lifting legs are inserted into the supporting legs, and the lifting legs are fixed to the supporting legs using the second latch at the required height, then the two solid lifting legs are respectively inserted into the two ends of the top rod, and the first slot corresponds to the second slot, and the first latch is inserted to fix the lifting legs to the top rod, and then the top arm of the hydraulic jack is lowered, and the hydraulic jack is removed. When the height needs to be changed, the top arm of the hydraulic jack is aligned with the disc, and the top arm of the hydraulic jack is lifted and contacts the disc, and is lifted to the required height, the first latch is removed, the lifting leg is removed, the height between the lifting leg and the supporting leg is readjusted, and then the lifting leg and the supporting leg are fixed by the second latch. The lifting frame has high stability and can be adjusted according to the required height. At the same time, it is more portable and convenient to use to meet different needs.
