Abstract:
1. A stamping apparatus for stamping a shading film, comprising: a stamping head being substantially cylindrical and has at least one blind hole defined in a periphery wall of one end of the stamping head radially; at least one locking member comprising a traverse locking tenon and a longitudinal locking tenon fixed to one end of the traverse locking tenon; a sleeving ring defining an axial sleeving hole, at least one radial locking hole, and at least one axial hole, the at least one radial locking hole communicating with the axial sleeving hole, the at least one axial hole communicating with the at least one radial locking hole; the sleeving ring comprising a stamping portion formed on a distal end thereof and surrounding the axial sleeving hole, wherein the at least one locking member is releasably assembled within the at least one radial locking hole of the sleeving ring and engages into the corresponding at least one blind hole of the stamping head, thereby locking the sleeving ring to the stamping head; the stamping portion matches with the stamping head for cooperatively stamping the shading film; and an elastic member, wherein the locking member is releasably assembled within the radial locking hole via the elastic member, the traverse locking tenon and the longitudinal locking tenon are respectively received within the radial locking hole and the axial hole of the sleeving ring, and the elastic member is received within the radial locking hole and resists against traverse locking tenon of the locking member.
