Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in an apparatus for attaching an outer blade to a reciprocating electric razor.

Conventionally, the outer blade of this type of electric razor is fixed to the outer blade frame in the direction of reciprocating movement of the inner blade, so when cutting beards, an impact force is applied to the outer blade and the outer blade is easily damaged. there were.

In view of this point, the present invention provides an outer blade in which a reinforcing plate having a loose fitting hole and protruding bullet pieces at both ends is fixed to both ends of a flexible outer blade blank plate having a large number of hair introduction holes. The outer cutter frame has an opening at the top and has a locking piece protruding from the inner wall of the opening perpendicular to the reciprocating direction of the inner cutter. The drawbacks of the conventional example were solved by attaching it in an arched manner.

The present invention will be explained below based on the illustrated embodiments.A is a synthetic resin plate 20 in which rectangular loose fitting holes 1, 1 are formed at appropriate intervals; elastic pieces 3, 3 are integrally protruded from both ends of the plate 20; A reinforcing plate is used to attach the bullet pieces 3 to opposite edges of the flexible outer blade blank plate, which has a large number of hair introduction holes 4, so as to protrude from the edges of the outer blade blank plate, thereby forming the outer blade Ak. B is the loose fitting hole 1, 1 in the opening inner wall 5, 5 perpendicular to the reciprocating direction Y-Y of the inner cutter G.
The outer cutter frame has an open upper surface with locking pieces 6, 6 protruding in correspondence with the outer cutter frame, and the outer cutter A is loosely fitted into the opening 1 and the locking pieces 6, 6 are loosely fitted into the holes 1, 1, respectively. The bullet pieces 3.3 are brought into elastic contact with the inner surfaces of opposing opening walls 8, 8, respectively, and are mounted in an arch shape to form an outer cutter body, and the outer cutter body having the above structure is mounted on the upper surface of the inner cutter G. A body E is arranged to reciprocate by a drive rod 9.
A reciprocating electric razor is constructed in which the inner cutter G and the outer cutter base plate are in contact with each other by the push-up spring 10 and the arched tension of the outer cutter a.

Since the present invention has the above configuration, when an impact force is applied to the outer cutter, the outer cutter moves due to the play in the loose fitting hole, and when it comes into contact with the opening wall of the outer cutter frame, the impact force is softened by the bullet. When the impact force is removed, the bullet automatically returns to its previous position.

Therefore, according to the present invention, when an impact force is applied to the outer cutter, it is relaxed, no unreasonable force is applied to the outer cutter, and the outer cutter is not damaged, thereby prolonging the life of the outer cutter.
