Abstract: The invention relates to a reset mechanism of the key duplication device which comprises a reset apparatus, a spindle and a body, wherein the spindle is inserted into the body and is rotatably connected to the body. Between workspace and a loading area, the body is repeatedly moveable along the spindle. The reset mechanism comprises an elastic member connected with the body. Elastic forces of the elastic member always act on the body and move the body toward the workspace. After the body is rotated to the loading area against the elastic forces of the elastic member, when a withdrawal force exceeds the elastic forces, the body automatically returns to the workspace under the influence of the elastic forces. The fewer and easier operating steps the more efficient work of the reset mechanism is, and the mechanism more conforms to the ergonomics design.
