TAPE HOLDING WHEEL FOR A TAPE DISPENSER

1 . A tape holding wheel for a tape dispenser being provided; said tape dispenser including a handle for users to hold, a standing board fixed at a side of said handle, a fixing post perpendicularly disposed on said standing board, and a sleeve superimposed on said fixing post; a plurality of parallel rails being protruded on an external circumference of said sleeve and parallel to an axle of said sleeve; said rails being able to axially engaged with a tape of a small dimension; said sleeve of said tape dispenser being further superimposed by a tape holding wheel; said tape holding wheel being able to axially engaged with a tape of a large dimension;

wherein, said tape holding wheel has an axial opening defined at a center thereof; parallel sliding grooves depressed in an inner wall of said tape holding wheel being defined correspondingly to said rails of said sleeve, thereby being synchronically motivated with said sleeve; a plurality of lengthwise supporting ribs being protruded on an external cambered surface of said tape holding wheel, parallel to an axle thereof; a propping part being integrally and laterally extended from a top end of each supporting rib, toward a direction to said external cambered surface of said tape holding wheel; a propping rib being axially extended on an external end of said propping part; a guiding ramp being formed on an introducing point of said propping rib; a blocking end being outward extended from an end of said propping part;

a first engaging unit being disposed on a front end of said tape holding wheel for said sleeve to firmly cooperate with said tape holding wheel; and

a second engaging unit being disposed on a rear end of said tape holding wheel for said sleeve to firmly cooperate with said tape holding wheel.

2 . The tape holding wheel as claimed in claim 1 , wherein, an outward crook is protruded from a fore part of said sleeve; two ripped grooves in a predetermined length are defined on two sides of said crook, respectively; a hook part of said crook stretches out of an external part of said sleeve; said first engaging unit comprises a contacting part which is formed on said front end of said tape holding wheel, corresponding to said crook.

3 . The tape holding wheel as claimed in claim 2 , wherein, said second engaging unit comprises a reversed hook which stretches inwardly from said rear end of said tape holding wheel; two ripped grooves in a predetermined length are defined on two sides of said reversed hook, respectively; a hook part of said reversed hook stretches out of an inner end of said tape holding wheel.

4 . The tape holding wheel as claimed in claim 1 , wherein, said second engaging unit comprises a reversed hook which stretches inwardly from said rear end of said tape holding wheel; two ripped grooves in a predetermined length are defined on two sides of said reversed hook, respectively; a hook part of said reversed hook stretches out of an inner end of said tape holding wheel; at least one depressed slot is defined on a fore part of said sleeve, corresponding to said reversed hook.

5 . The tape holding wheel as claimed in claim 1 , wherein, said supporting ribs are protruded from said external circumference of said tape holding wheel, corresponding to two sides of said sliding grooves.

6 . The tape holding wheel as claimed in claim 1 , wherein, said propping parts are formed into an arc.

7 . The tape holding wheel as claimed in claim 1 , wherein, said propping parts face to each other; said propping parts are extended from top ends of said supporting ribs toward a direction to a middle of two sliding grooves.

8 . The tape holding wheel as claimed in claim 1 , wherein, said propping rib is outward extended from said external end of each propping part.

9 . The tape holding wheel as claimed in claim 1 , wherein, each propping rib has a top end formed into an arc.
