Patent ID: 8590162

Claim:
A shaver, comprising: a removable cartridge, comprising: a cartridge body shaped such that part of upper and lower surfaces thereof is open; at least one blade mounted to the lower surface of the cartridge body; a connector mounting part provided on the upper surface of the cartridge body; and a connector mounted to the connector mounting part, and having at a rear end thereof a holder mounting part; and a handle assembly, comprising: a handle body; a housing provided on a front end of the handle body; a holder mounted to a front end of the housing in such a way as to rotate around a pivot shaft; means for removably coupling the holder to the holder mounting part; means for separating the holder from the holder mounting part when physical force is applied to the means for removably coupling by external force, the holder being restored to an original position thereof by elastic force, the means for separating being installed in the housing and being operated in conjunction with the means for removably coupling; and means for elastically supporting rotating motion of the holder using elastic force, the means for elastically supporting being installed in the housing and being operated in conjunction with the holder, wherein the means for removably coupling comprises: a removing protrusion provided on a center of an upper portion of a rear end of the holder mounting part; elastic steps extending downwards from opposite sides of the removing protrusion, and configured to be elastically rotated by the removing protrusion; and a removing hook provided on a front end of the holder to correspond to each of the elastic steps, the means for separating comprises: an actuating button mounted to an upper surface of the housing, and having an extension part which extends into the housing; a pusher installed in the housing, and comprising a pusher protrusion which is provided on a front end of the pusher to be in close contact with the removing protrusion of the holder mounting part, and an insert hole which is formed in a rear end of the pusher so that the extension part is inserted into the insert hole; and an elastic member providing the elastic force functioning to elastically support the pusher, and the means for elastically supporting comprises: an inner housing installed in the housing, and defining a plunger mounting space in which a plunger can be slid; the plunger mounted to a front end of the plunger mounting part, and having a contact protrusion which is in close contact with a rear end of the holder; a plunger guide mounted to a rear end of the plunger mounting part; and an elastic member interposed between the plunger and the plunger guide, and providing the elastic force elastically supporting the plunger.
