## Abstract

A goods propulsion device and a shelf with the propulsion device include a partition plate, a push plate slidably connected with the partition plate, a gear rack configured on the partition plate, a gear rotatably connected to the push plate and a reset member connected to the push plate and the partition plate. The gear is meshed with the gear rack. The gear rack is configured along the length direction of the partition plate. The reset member is used for driving the push plate to reset relative to the partition plate. The present invention has a simple and compact structure. Users can assemble the goods propulsion devices with different types or sizes of bottom plates according to their actual needs.
