Support device for car jack, has hub unit supported on rotatable unit using support rod in functional position of device, where rod and rotatable unit are vertically aligned to base plate

摘要

The device has a hydraulic cylinder, and two pulling units (130) that are swivellably attached at a hub arm (20) using bolts and are held under tension using coil springs, where the parallel distance of pulling units corresponds to the distance of rotatable bolts (123) of rotatable units (115). Each pulling unit is provided with a groove, where the width of groove corresponds to the diameter of bolts (123). A hub unit (30) is supported on the unit (115) using a support rod (102) in a functional position of the device, where the rod and the unit (115) are vertically aligned to a base plate.
