[0040] As Figures 6-9As shown, an electromagnetic drive module 2 includes a base plate 21 and a telescopic core rod 22. The telescopic core rod is mounted above the base plate via a precision-positioning linear rolling bearing 1. The base plate has a first positioning hole 211 that mates with a first positioning pin.

[0043] It should be noted that the electromagnetic driving module disclosed in the application can also be applied to other occasions, such as a rocking bed.
