Reset mechanism

A reset mechanism for a key duplication device, wherein the reset mechanism comprises a reset apparatus, a spindle and a body, wherein the spindle is inserted into the body and is rotatably connected to the body, wherein the body is repeatedly moveable along the spindle, between a workspace and a loading area, wherein

• the reset apparatus comprises an elastic member connected with the body, wherein elastic forces of the elastic member always act on and move the body toward the workspace, wherein 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 influence of the elastic forces, wherein
• the reset mechanism comprises a first subshaft, a first elastic member and a tension spring, wherein
• the first subshaft is provided with a drive part, a first ratchet, a second ratchet, a third ratchet and a second wedge respectively, wherein the two ends of the first subshaft 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 one end of the tension spring is connected with the body and another 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, and 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, wherein
• the reset mechanism comprises the reset apparatus comprising a second subshaft connected with the body, wherein
• the second subshaft is parallel to the first subshaft and one end of the second wedge is installed on the second subshaft, and corresponds to the first wedge, wherein
• when the second wedge moves axially along the second subshaft to the corresponding position of the first wedge, the position of the second wedge is limited by the position of the first wedge.

• the reset apparatus comprises an elastic member connected with the body, wherein elastic forces of the elastic member always act on and move the body toward the workspace, wherein 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 influence of the elastic forces, wherein
• the reset mechanism comprises a locking device, said locking device comprising a pin member and a toggle lever, wherein the toggle lever is inserted into the body and rotates relative to the body, wherein
• a second wedge is provided with a groove adapted to the pin member, and wherein the pin member controlled by the toggle lever is inserted or separated from the groove, thereby tightening or loosening the second wedge, wherein
• the locking device further comprises a rotor, a pressing block and a second elastic member, wherein
• the pin member is inserted into a connection block connected with the body, wherein the elastic member is arranged between a connection block and the pin member, and is fitted on the pin member, wherein
• the pressing block is hinged to the connection block, wherein one end of the pressing block is pressed on the pin member and another end is connected to the rotor, and wherein
• the rotor is rotatable by the toggle lever to rotate the pressing block, thereby pressing or loosening the pin member which is inserted or separated from the groove on the second wedge.
