The invention discloses a seat lifting mechanism. The seat lifting mechanism comprises an upper support, a lower support, a left shear rack and a right shear rack. The left shear rack and the right shear rack are each internally provided with an inner shear plate and an outer shear plate. The inner shear plates and the outer shear plates are provided with a rotary volute spiral spring shaft. A ratchet wheel and two volute spiral spring coils are arranged on the volute spiral spring shaft. The two volute spiral spring coils are located on the two sides of the inner shear plates respectively, one end of each volute spiral spring coil is fixed to the volute spiral spring shaft, and the other end of each volute spiral spring coil is fixed to the corresponding inner shear plate. Two upper sliding grooves and two lower sliding grooves are formed in the corresponding positions of the upper support and the lower support. Lower sliders are installed in the two lower sliding grooves respectively. An upper slider is installed in one of the two upper sliding grooves. A locking slider is arranged in the other of the two upper sliding grooves. A lower slider connection rod is connected between the two lower sliders. The upper slider and the locking slider are connected through an upper slider connection rod. A gear groove is formed in the end of the locking slider. The seat lifting mechanism further comprises a stabilizing mechanism. Compared with the prior art, the seat lifting mechanism is convenient and stable to operate.
