ABSTRACT:
The present invention discloses a device with an elastic shifting mechanism, which comprises: a body and a movable element, wherein the body has a first snap-fit element, and the movable element has a second snap-fit element, and the movable element is installed to the body; the body/the movable element has a transmission element, and the movable element/the body has a drive element, and the drive element engages with the transmission element; two ends of an elastic element are respectively fixed to the transmission element and the body/the movable element; when said movable is being moved to enable the second snap-fit element to snap-fit the first snap-fit element, the drive element drives the transmission element to wind up the elastic element; when the second snap-fit element is disengaged from the first snap-fit element, the elastic element releases elastic force to move the movable element. Thereby, the device with an elastic shifting mechanism disclosed by the present invention has an automatic shifting function.
