The present invention discloses a scissor jack comprising four arms hingedly arranged to provide two opposite elbows between a base and a load support. A pair of trunnions are provided with an outer trunnion at one outer elbow and a threaded trunnion at another outer elbow opposite to the one outer elbow connected through a threaded shaft. The inner third trunnion is connected to two rods to form a yoke. The yoke is configured to slideably pass through the outer trunnion of the one outer elbow to extend beyond the one outer elbow. A pair of levers are provided which are configured to be secured to the inner third trunnion. The scissor jack further comprises springs or any other retaining mechanism attached to a pair of levers, to ensure that the pair of levers return to their original location or position when the scissor jack is lowered.
