The invention belongs to the technical field of hoisting equipment, and particularly relates to a vehicle-mounted mechanical jack which comprises a base, a first contact plate is arranged above the base, two second contact plates are arranged on the two sides of the first contact plate, and a first lifting assembly is connected between each second contact plate and the base. A second lifting assembly is connected between the first contact plate and the base, a moving plate is fixedly arranged on the lower side of each first lifting assembly, two magnetic sliding blocks are fixedly arranged on the two sides of the lower end face of each moving plate, and a first supporting block is fixedly arranged on the lower end face of each magnetic sliding block; four second supporting blocks are fixedly arranged on the lower end face of the base. The supporting positions of the first supporting block and the second contact plate can be adjusted firstly, then the lifting effect is achieved through the first lifting assembly and the second lifting assembly, and therefore it is guaranteed that the supporting strength is enhanced before the jack is lifted continuously, and the jack is prevented from sliding.

    本发明属于起重设备技术领域,尤其涉及一种车载式机械千斤顶,包括底座,所述底座的上方设有第一接触板,所述第一接触板的两侧设有两个第二接触板,每个所述第二接触板与底座之间连接设有第一升降组件,所述第一接触板与底座之间连接设有第二升降组件,每个所述第一升降组件的下侧固设有移动板,每个所述移动板的下端面两侧固设有两个磁性滑块,每个所述磁性滑块的下端面固设有第一支撑块,所述底座的下端面固设有四个第二支撑块。本发明能够先进行调整第一支撑块和第二接触板的支撑位置,再通过第一升降组件与第二升降组件进行升降作用,从而保证了千斤顶不断抬高前加强支撑强度,防止千斤顶滑动。
