<p>This design is about a knife sharpener which can polish one or both sides of a blade. It connects a gear(10) to the both sides of a motor(12), connects a gear connection tube(9) forming a hole within to the gear(10), installs an abrasive control spring on the gear connection tube(9), inserts one-side part of abrasive connecting rod(8) to the inside hole of the above gear connection tube(9), combines the other-side part with the abrasive(4) having a leathern blade protective(7) built in the central part, thus forms one pair ofboth-side abrasives(4), installs two or three pairs of the above both-side abrasives, fits one of the shake prevention security springs(2) installed at the left and right sides of the V-formed polishing insertion hole located on top of the above central both-side abrasive(4) with a motor operating switch(3) and connects it with a motor electrically. This enables the motor operating switch(3) to be pressed and operated, the motor (12) to be driven, two or three pairs of both-side abrasives(4) to be rotated by a gear(10), if a knife is inserted into the polishing insertion hole(14) by opening a polishing security cover(1), the motor to be stopped by installing a polishing completion perception sensor(15) and perceiving a polished knife, and the single-side blade to be polished by installing a single-side abrasive at one side of the motor.</p> |
