1. A reciprocating type head-moving razor including a head part, having a drive motor and a double cutting blade, which is movable relative to a body part, wherein
the body part has an upper end disposed below the lower surface of the head part, the head part is provided at the rear surface thereof with a receiving part, in which a protrusion formed at the upper end of the body part is inserted, and the body part is provided at opposite sides of the upper end thereof with supporting walls, to which opposite sides of the head part are attached, respectively, such that the head part can be moved a predetermined angular distance.
2. The razor as set forth in claim 1, wherein the head part is constructed such that an insertion part is attached, at a right angle, to a drive shaft of the drive motor and an eccentric shaft formed at the upper end of the drive shaft to angularly move the cutting blade.
3. The razor as set forth in claim 1, wherein the head part can be moved an angular distance of 30 degrees to 60 degrees either manually or by the operation of a rack and pinion unit, which is operated by a moving switch disposed at one side of the main body.
The claims below are in addition to those above.
