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.

Claim (Index 4):
The reset mechanism according to  claim 3 , wherein the mechanism comprises a first subshaft, a first elastic member and a tension spring, wherein\n the first subshaft is provided with the drive part, a first ratchet, a second ratchet, a third ratchet and the second wedge respectively, wherein the two ends of the first sub shaft are rotationally connected with the body, wherein the drive part is fixedly connected with the first ratchet and is rotatable with respect to the first subshaft, wherein the one end of the tension spring is connected with the body and the other end is connected with the drive part accordingly, and the drive part can be reset, wherein the second ratchet is fixed to the first subshaft and the first ratchet drives the second ratchet to rotate directionally, wherein the third ratchet is fixed to the second wedge, and the third ratchet and the second wedge move axially together in relation to the first subshaft, wherein the third ratchet is provided with a first detent and a second detent, wherein the first detent and the second detent are spaced from each other, and are adapted to the second ratchet, wherein when the second ratchet engages the first detent of the third ratchet, the second wedge is driven away from the first wedge by the third ratchet, wherein the first elastic member is provided between the body and the second wedge, wherein when the second ratchet engages the second detent of the third ratchet, the second wedge is moved to a position limited by the first wedge.
