Beschreibung
Zusammenfassung:	The hydraulic jack convenient to adjust comprises a fixed chassis, a jack body, a hydraulic adjusting device and a supporting anti-skid device, the jack body is welded to the top of the fixed chassis, and a connecting boss is integrally formed on one side of the periphery of the fixed chassis; a hydraulic adjusting device is connected to the periphery of the connecting boss through bolts, a supporting anti-skid device is installed at the top of the output end of the jack body, four built-in storage grooves distributed in an annular array are formed in the bottom of the fixed chassis, and positioning claws are embedded in inner cavities of the built-in storage grooves. The hydraulic adjusting device comprises a connecting frame and a hydraulic cylinder which are fixed to the periphery of the connecting boss through bolts. According to the hydraulic jack convenient to adjust, the supporting and jacking stability of loaded objects can be improved, meanwhile, the possibility that soil is pressed to deform and cau
