Description

technical field [0001] The invention relates to the field of auto parts, in particular to a scissor jack. Background technique [0002] Scissor jack is a kind of lifting equipment, which is mainly used for jacking up and supporting small-tonnage cars such as cars. The bearings of traditional jacks are made of metal, but the bearings made of metal are noisy and easy to accumulate dust during use. Contents of the invention [0003] Aiming at the problems existing in the prior art, the invention provides a scissor jack to solve the problems that the traditional scissor jack adopts metal bearings with high noise and easy accumulation of dust. [0004] The technical solution of the present invention is: a scissor jack, including an upper bracket and a lower bracket, the upper bracket and the lower bracket are connected by a threaded rod, one end of the screw rod is fixed with a bearing, and the bearing includes PA66 Bearing cage and balls, the edge of the bearing cage is prov...
