DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a safety cover for a sculpted knife equipped with an illumination lamp according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3, a safety cover for a sculpted knife equipped with an illumination lamp according to an embodiment of the present invention includes:

A front cover 12 to which a lower end is closely attached to the piece to be plated 10 and to which an illuminating lamp 11 is mounted on the inner side;

A protective cover 13 formed of a transparent material such as an acrylic material extending from the upper end of the front cover 12;

A handle 16 of a piece knife 15 for engraving the piece to be plated 10 is detachably connected to one end of the protective cover 13 by a fixing pin 14, A holding portion 17;

A battery 18 mounted on the holding part 17 or the protective cover 13 for supplying power to the illumination lamp 11 through a power cable;

A limit switch (19) for interrupting a power source applied to the illumination lamp (11) by folding the holding part (17) against the protective cover (13);

A state in which the holding portion 17 that is foldably connected to the protective cover 13 is expanded (a state in which the upper surfaces of the protective cover 13 and the holding portion 17 are flush with each other) And an elastic member 20 (e.g., a torsion spring can be used).

More preferably, the illumination lamp 11 may be an LED lamp or an incandescent lamp. The illumination lamp 11 may be sufficiently used as a lamp having a brightness capable of illuminating the working position of the engraving knife 15 on the punched plate 10.

The holding portion 17

The cutout portion 21 may be formed on one side of the holding portion 17 so that the knob 16 of the knife 15 having an outer diameter larger than the inner diameter of the holding portion 17 can be engaged.

The front cover 12 is formed on the bottom surface of the front cover 12 to prevent the bottom end of the front cover 12 from hanging on the pierced plate 10 during operation, And a U-shaped latching bending portion 22 may be provided.

As the battery 18, two 1.5 V mercury batteries or two 1.5 V batteries may be used.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an example of the use of a safety cover for a carpet knife equipped with an illumination lamp according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIGS. 1 and 2, when the handle 16 of the engraving knife 15 is engaged with the holding portion 17 and the engraved knife 15 is not used to operate the engraved plate material 10 (A state in which the work is being prepared, or when the work piece 15 is not used by resting temporarily during work).

When the knob 16 of the engraving knife 15 is engaged by the cutout portion 21 formed in the holding portion 17, the outer diameter of the knob 16 is not limited. That is, since the holding portion 17 is elastically deformed in the radial direction by the cutout portion 21, the knob 16 of the knife 15 having an outer diameter slightly larger than the inner diameter of the holding portion 17 is engaged .

At this time, the handle 16 of the engraving knife 15 is kept in the form of a straight line with respect to the protective cover 13, so that the limit switch 19 is kept OFF. Accordingly, the illumination lamp 11 connected to the battery 18 so as to be energized maintains the unlit state because the limit switch 19 does not supply power from the battery 18.

The protective cover 13 and the holding portion 17 are expanded so that the upper surface of the protective cover 13 is kept in the same plane by the elastic force of the elastic member 20, The handle 16 of the handle 15 can maintain its shape.

1 and 3, the handle 16 of the engraving knife 15 is caught by using the engraving knife 15 coupled to the holding portion 17 to engrave the engraved engraving plate 10 A pressing force is exerted on the elastic member 20 so that the handle 16 of the engraving knife 15 can move freely against the protective cover 13 maintaining the horizontal state, Thereby maintaining an inclined state at an angle.

At this time, the lower end of the front cover 12, which is formed at the front end of the protective cover 13 in a vertical direction, is kept in close contact with the punched plate 10.

The limit switch 19 is kept ON when the knob 16 of the engraving knife 15 is inclined at an angle with respect to the protective cover 13 so that the battery 18 The lighting lamp 11 connected to be energized can receive power from the battery 18 by the limit switch 17 and maintain the lighting state.

Therefore, when the handle 16 of the engraving knife 15 is held while the engraved portion of the engraved knife 15 is illuminated by the illumination lamp 11, It is possible to perform the engraving operation by pushing it in an arbitrary direction on the screen 10.

At this time, the lower end of the front cover 12 is prevented from being caught by the recessed bending portion 22 formed at the lower end of the front cover 12 by the recessed portion (not shown) formed in the punched plate 10 can do.

Therefore, the engraving knife 15 can be freely pivoted on the plated plate 10 in any direction.

When the operating knife 15 is pushed on the pierced plate 10 during the operation, the protective cover 13 is in the form of a straight line with the holding portion 17 due to the elastic restoring force of the elastic member 20 . Therefore, it is possible to prevent the operator from being injured by blocking the direct contact between the body part of the operator and the knife 15.
