Abstract: A toy gun includes a gun body, a magazine, and a gun elastic member. The gun body includes one of a retractable latch and a convex edge. The magazine is slidably mounted at the gun body and includes another one of the latch and the convex edge. The latch is configured to abut against the convex edge to stop the magazine from sliding relative to the gun body. The gun elastic member is configured to be compressed when the latch abuts against the convex edge and drive the magazine to slide relative to the gun body when the latch is separated from the convex edge.

Abstract: The present disclosure provides a Mecanum wheel. The Mecanum wheel includes a spoke, a hub, and a plurality of rollers disposed on an outer edge of the spoke. The spoke includes a receiving space to house the hub. The Mecanum wheel further includes a cushioning member, one end of the cushioning member being connected to the spoke, and the other end of the cushioning member being connected to the hub. In response to receiving an impact force, the cushioning member deforms to cause a displacement change of the hub relative to the spoke.
