The invention discloses a hauling-up device capable of elastically lifting a jack. The hauling-up device capable of elastically lifting the jack comprises a trolley base body and the manual hydraulic jack. An inward concave square groove is formed in the middle of the upper surface of the trolley base body. The manual hydraulic jack is arranged in the square groove. A through hole corresponding to the bottom of the manual hydraulic jack is formed in the bottom of the square groove. The bottom of the manual hydraulic jack extends to the lower portion of the trolley base body through the through hole. Baffles are arranged on the two sides of the manual hydraulic jack respectively. Springs are arranged between the baffles and the square groove for supporting and connecting the baffles and the square groove. In this way, according to the hauling-up device capable of elastically lifting the jack, when lifting is conducted, the manual hydraulic jack is stressed to descend, so that the bottom of the manual hydraulic jack is down to the ground, and the lifting stability and the lifting safety are improved; when non-lifting moving is conducted, the manual hydraulic jack is supported by the springs to be suspended in midair, so that the contact between the manual hydraulic jack and the ground is avoided, and the moving convenience is improved.
