The height adjustment mechanism comprises a lifting column, a rotor assembly, a reducing worm gear, a pulley, an elastic piece and a rope. The rotor assembly can be located on the lifting column in a sliding manner in the vertical direction. The pulley is rotationally mounted at the upper end of one side of the lifting column. The reducing worm gear is rotationally mounted at the lower end of one side of the lifting column. A gear groove in the reducing worm gear is of a structure gradually reduced from one end to the other end. The upper end of the elastic piece is fixedly connected with the upper end of the lifting column, and the lower end of the elastic piece is connected with the upper end of the rope. The other end of the rope is closely wound around the gear groove of the reducing worm gear to turn, then is wound around the pulley to turn and is finally connected with the rotor assembly. In the lifting process of the displayer, the elastic force of the elastic piece is used for providing supporting, meanwhile, tension changes generated by different stretching degrees of the elastic piece are balanced by changing the diameter of the gear groove of the reducing worm gear, stress balancing is achieved, the displayer can keep in a suspended state at any position, and height adjustment of the displayer is easy and convenient.

The invention provides an embedded safety elevator which comprises an elevator safety lifting device and an elevator car. The elevator safety lifting device comprises a transmission rod, spiral lifting assemblies and track nut pipes. A spiral slide corresponding to a spiral slide on the inner wall of the corresponding track nut pipe and capable of being meshed with the spiral slide is arranged on the surface of a sliding bolt of each spiral lifting assembly, and each spiral lifting assembly is embedded in the corresponding track nut pipe. A first bevel gear is arranged on the end portion of the transmission rod, the bevel gear at the opening position of the track nut pipe is meshed with a second bevel gear on the end portion of the sliding bolt arranged in the corresponding spiral lifting assembly, and two spiral lifting assemblies and two track nut pipes matched with the assemblies are provided and symmetrically arranged on two sides of the elevator car. The embedded safety elevator meets the requirement for multi-direction opening, and the manufacture cost and the use cost of the elevator are effectively reduced.
