Reciprocating linear razor

A reciprocating linear razor comprising:

• a housing functioning as a grip unit;
• a head unit coupled to one side of the housing;
• a razor blade cartridge disposed in a front surface of an upper portion of the head unit for cutting;
• an eccentric cam module making the razor blade cartridge perform a reciprocating motion in a cutting direction, and
• at least one or more of vacuum-guards disposed parallel to the razor blade cartridge in a front surface of the head unit, wherein,
• when a vibration is generated by a reciprocating motion of the razor blade cartridge, the vacuum-guard vibrates together, and thus, a compression motion and an expansion motion are provided, wherein
• the vacuum-guard comprises:
• a first guard adjacent to the razor blade cartridge in one side of a cutting direction of the razor blade cartridge, and disposed parallel to the razor blade cartridge;
• and
• a second guard adjacent to the razor blade cartridge in other side of the cutting direction of the razor blade cartridge, disposed parallel to the razor blade cartridge and the first guard, disposed in the same plane as the first guard, and disposed to face the first guard with respect to the razor blade cartridge,
• wherein the first and second side elastic cover guides are symmetrically disposed at first and second sides of the head unit, respectively, to fix the razor blade cartridge and the vacuum-guard to the head unit, the first and second sides being vertical with respect to a cutting direction of the razor blade cartridge, such that the razor blade cartridge and a vacuum-guard are configured to be attached to and detached from a front surface of an upper portion of the head unit.
