Suspension traction seat elevator

The invention aims to provide a suspension traction seat elevator. The suspension traction seat elevator comprises a seat, a rhombus rail, V-shaped wheels, a driving motor, a rail supporting plate, a seat suspending plate, a guide rack, a traction connection plate and V-shaped wheel connection plates. The rhombus rail is fixed on the rail supporting plate. An upper supporting V-shaped wheel and alower movable V-shaped wheel are fixed on the seat suspending plate and are overlapped at the upper and lower edges of the rhombus rail respectively. An upper traction V-shaped wheel and a lower traction V-shaped wheel are fixed on the traction connection plate and are overlapped at the upper and lower edges of the rhombus rail respectively. The upper supporting V-shaped wheel and the upper traction V-shaped wheel are connected with a universal connector through the V-shaped wheel connection plates. The driving motor is fixed on the traction connection plate. The guide rack is fixed on the rhombus rail. The guide rack
