Layered and detachable pelvis three-plane model display device with pelvis bottom

The invention discloses a layered and detachable pelvis three-plane model display device with a pelvis bottom, relates to the technical field of teaching aids, and solves the problems that an existingpelvis model is generally of an integral structure of a pelvis, it is difficult to well display the internal structure in use, particularly, the structure is difficult to display when the pelvis three-plane structure is used, and the teaching effect is not good. The device comprises a mounting base; the rear part of the mounting base is fixedly connected with a group of display driving pieces; agroup of overturning driving sliding pieces are connected into display cross rods in a sliding manner; the inner sides of the display cross rods located at the same height are jointly and rotationallyconnected with a set of model mounting bases. The device is of a three-layer structure, a model can be rotated while the three-layer model rises synchronously, a three-plane structure in the model iswell displayed, the display
