The utility model discloses a many function display of modularization mechanism, include, install fast part, positioning element, drive part and the function display module dialled on the bottom plate, stir the cam in good time function display module of stirring respectively among fast driving lever part, the locating lever among the positioning element and the drive part who dials in the part. The beneficial effects are that: because make into independent module with each function, just peripheral mechanism is supporting has relevant combination mechanism, consequently, can change corresponding module in a flexible way according to different function needs, can realize corresponding demonstration function, and can show as required on any position that the off -balancesheet was seen. In addition, also can install the indication mechanism of multiunit, the simultaneous display multiple functions, this indication mechanism has improved design efficiency, has shortened the design cycle to manufacturing cost has been reduced.
