This invention discloses a housing insertion device and a multi-station housing insertion equipment. The housing insertion device includes a mounting frame, a positioning and bearing module, and a push rod assembly. The positioning and bearing module carries the receiving component and element. The push rod assembly includes a rod, a sliding sleeve, a pressure sensor, a pressure plate, and a magnetic attractor. The rod extends along a first direction, and the sliding sleeve is fitted and slidably connected to the rod.
