[0040] Specifically, a hydraulic pump truck 5 is arranged on one side of the fixed bracket 1, and the hydraulic oil port of the hydraulic pump truck 5 is connected to the hydraulic oil port of the hydraulic jack body 3 through a hydraulic connecting pipe 4. The hydraulic pump truck 5 has a built-in hydraulic pump and a hydraulic oil tank, and uses the hydraulic pump to inject or extract hydraulic oil into the hydraulic jack body 3.

[0041] Furthermore, the insert block 603 is configured to be square, and the insert block 603 is adapted to the slot 6011 ; the square insert block 603 remains stable after being inserted into the slot 6011 .
