The invention provides a lifter with a short mounting distance and a large stroke. The lifter comprises a top plate, a bottom plate and a driving device used for controlling the top plate to ascend and descend, wherein the driving device comprises a driving motor and a lead screw, a lead screw nut is arranged on the lead screw, the driving device is fixed between the top plate and the bottom plate, a connecting plate is arranged on the driving device, connecting rod sets are arranged between the top plate and the bottom plate, the two ends of each connecting rod set are slidably connected withthe bottom plate and the top plate respectively, the middle of each connecting rod set is rotatably connected with the side face of the connecting plate, the driving device controls the connecting plate to ascend and descend, and the connecting plate drives the connecting rod set to move for ascending and descending of the top plate. The lifter has the advantages that the stroke of the lifter canbe increased by changing the connecting rod sets while the mounting distance is not increased.
