Claims

1. A multi-functional stationery tool combination, comprising:

a top casing (1), a bottom casing (3) connected to said top casing, a top guiding plate (2) connected between said top and bottom casings and a bottom guiding plate (4) connected between said top guiding plate and said bottom casing, said top casing having a narrow opening (101) therethrough, said top guiding plate having a protruding edge (20) thereon and a fixation hole (21) therethrough, said top guiding plate having a stepped platform (23) defining a measuring tape space with said top casing;

a slidable base (12) slidable mounted along said protruding edge;

a blade (N) mounted for sliding with said slidable base between said top casing and said top guiding plate;

fastening means (11) for connecting said slidable base to said blade, said fastening means having at least a portion extending through said narrow opening of said top casing for movement along said narrow opening for guiding the sliding movement of said blade;

a staple removing device (R) pivotally mounted to said fixation hole of said top guiding plate for pivotal movement on said top guiding plate;

measuring tape means (M) mounted in said measuring tape space for discharging and retrieving a measuring tape;

said bottom guiding plate including a plurality of protruding elements (41);

a pencil sharpener (S) engaged with at least one of said protruding elements of said bottom guiding plate for positioning said pencil sharpener on said bottom guiding plate;

a container (5) for receiving pencil sharpening debris, said container having an opening facing said sharpener and being engaged with at least one of said protruding elements of said bottom guiding plate for positioning said container on said bottom guiding plate;

said top and bottom guiding plates each having a first elongated slot (25,

     42) with the first elongated slot of said bottom guiding plate extending parallel to the first elongated slot of said top guiding plate, said top and bottom guiding plates each having a second elongated slot (26,

     43) with the second elongated slot of said top guiding plate extending parallel to the second elongated slot of said bottom guiding plate;

a storage box (6) having a protruding knob (6) slidably engaged in the first elongated slot of each of said top and bottom guiding plates for sliding movement of said storage box along said first elongated slots and between said top and bottom guiding plates;

a stapler (B) having an engaging element (B2) slidably engaged with said second elongated slot of each of said top and bottom guiding plates for sliding of said stapler along said second elongated slots and between said top and bottom sliding plates;

a paper punch (C) mounted between said top and bottom guiding plates for punching a hole in paper;

a knife (D) pivotally mounted to said bottom guiding plate;

said bottom guiding plate having an L-shaped opening (40) therethrough and said bottom casing having an elongated opening (31) therethrough with at least a portion of said L-shaped opening extending parallel to said elongated opening;

a fixation element (A3) slidably mounted along and between said L-shaped and elongated openings;

two scissor blades (A1) pivotally mounted to said fixation element and being slidable between a storage position between said bottom guiding plate and said bottom casing, and a use position extending from said bottom guiding plate and bottom casing with sliding movement of said fixation element along said elongated and L-shaped openings;

and spring means (A2) connected between said two scissor blades for biassing said scissor blades to spread when said scissor blades are in their use position extending out of said bottom guiding plate and said bottom casing.

2. The combination of claim 1 wherein said top casing includes a horizontal depression (10) extending around said narrow opening for receiving said fastening means, said fastening means comprising a fastening nut (11) connected to said slidable base and extending through an opening in said blade.

3. The combination of claim 1 wherein said paper punch comprises a base (C1) connected to said top and bottom casings, a punching element (C20) mounted between said top and bottom guiding plates and a pressing element (C3) mounted for movement between said top and bottom guiding plates for pressing said punching element to cooperate with said base to punch a hole in paper.

4. The combination of claim 1 wherein said bottom casing includes a protruding periphery (32) for receiving said two scissor blades in their storage position between said bottom guiding plate and said bottom casing, said spring means comprising an L-shaped elastic spring (A2) having opposite ends each engaged with one of said scissor blades.

5. The combination according to claim 1 including a partition plate (48) fixed between said top and bottom guiding plates and over said storage box for covering said storage box when said storage box is between said top and bottom guiding plates.
