The invention relates to the technical field of medical instruments, in particular to a transposable soft-magnet feeding device. The transposable soft-magnet feeding device comprises a first platform and a controller, wherein a horizontally placed expansion and contraction device is mounted on the first platform; a second platform is fixedly connected to the extending end of the expansion and contraction device; a first lifting platform and a second lifting platform are sequentially arranged on the second platform in the expansion and contraction direction of the expansion and contraction device; a first trigger and a second trigger are arranged at two ends of the second platform respectively; the first trigger, the first lifting platform, the second lifting platform and the second trigger are sequentially arranged from left to right; and the controller is electrically connected with the first trigger, the second trigger, the first lifting platform and the second lifting platform. By virtue of close cooperation between all structures and multi-point regulation and control of the controller, the overall structure is rapid and smooth in running and high in degree of automation; and owing to adoption of high-capacity members, the product production efficiency is high, and the manual cost is low.
