The invention provides a jacking mechanism which comprises a two-way threaded lead screw, a first nut, a second nut, a first swing part, a second swing part, a guide part, a first supporting part and a second supporting part. The first rotating direction section of the two-way threaded lead screw is in threaded connection with the first nut, and the first nut is rotationally connected with the lower end of the first swing part; the middle of the first swing part is rotationally connected with the top of the carriage, the upper end of the first swing part is rotationally connected with the middle of the first supporting part, the lower end of the first supporting part is rotationally connected with the guide part and can move relative to the guide part, and the upper end of the first supporting part is rotationally connected with the top cover. The connection mode of the second nut, the second swing piece and the second supporting piece is correspondingly the same as that of the first nut, the first swing piece and the first supporting piece, the bidirectional threaded lead screw is horizontally arranged and floats up and down relative to the carriage, and the guide part is fixedly arranged at the top of the carriage. According to the technical scheme, the driving torque in the lifting process is reasonable, the structural stability is good, and the market prospect is wide.
