The drive conversion mechanism and the cutting mechanism are disposed inside the upper housing 12. The drive mechanism, the transportation mechanism and the cutting control mechanism are disposed,inside the lower housing 5. The drive mechanism includes a button 1, a spring 2, a double linked gear 3 and a rack 4. One end of the button 1 is rotatably connected with the lower housing 5, and the other end thereof is supported by the spring 2. A sector gear on the button 1 is engaged with a small gear of the double linked gear 3, and a big gear of the double linked gear 3 is engaged with straight teeth of the rack 4. A guiding groove for the rack 4 and support shafts for respectively fixing the double linked gear 3 and the button 1 are provided on the inner wall of the lower housing 5. The transportation mechanism includes a one-way pawl 7, a big roller 6, a rubber ring 10, a small roller 9 and a transportation wheel 11. The one-way pawl 7 and the big roller 6 form a ratchet wheel assembly. Teeth of the one-way pawl 7 are engaged with the straight teeth of the rack 4. The big roller 6, the small roller 9 and the transportation wheel 11 are connected by the rubber ring 10. A support shaft for fixing the one-way pawl is provided on the inner wall of the lower housing 5. The big roller 6 drives the transportation wheel 11 via the rubber ring 10 to transport the adhesive tape in the same direction. The small roller 9 is disposed on a small roller bracket 22. Two raised ribs protruding above the top surface of the small roller bracket are respectively provided at two sides of the small roller bracket 22 in order to limit the swing of the adhesive tape towards the two sides. A support shaft for tightening a rubber belt along with the ratchet wheel assembly is provided in the lower housing 5. The cutting control mechanism includes a swaying wheel 8 rotatably installed in the lower housing 5. A column on one end of the swaying wheel 8 is stretched into a slide groove of the front end of the rack 4 so as to achieve a movable connection. A support shaft for fixing the swaying wheel 8 is provided on the inner wall of the lower housing 5. The drive conversion mechanism includes a swaying rod 18, a torsion spring 19, a pressing rod 17 and a tension spring 20. The swaying rod 18 and the pressing rod 17 are connected via the torsion spring 19, and the upper housing 12 and the pressing rod 17 are connected via the tension spring 20. Support shafts for respectively fixing the swaying rod 18 and the tension spring 20 are provided on the inner wall of the upper housing 12. The cutting mechanism includes a cutting seat 16, a cutting blade seat 14 and a cutting blade 13. The cutting blade 13 is assembled on the cutting blade seat 14 to form a cutting blade assembly. The cutting blade assembly is integrally installed in an inner groove of the cutting seat 16. A guide groove for the cutting seat is provided in the inner wall of the upper housing 12. The cutting seat 16 presses the adhesive tape against the transportation wheel before the cutting blade 13 cuts the adhesive tape. The cutting blade 13 cuts off the adhesive tape in a direction perpendicular to the adhesive tape. The pressing rod 17 presses the cutting seat 16 and the cutting blade assembly downwardly when rotating downwardly. The cutting seat 16 and the transportation wheel 11 are firstly press the adhesive tape, and then the cutting blade 13 cuts off the adhesive tape. A support shaft for fixing the upper housing 12 is provided on the inner wall of the lower housing 5, so that the upper housing 12 is assembled in the lower housing 5 and is rotatable around the support shaft. Support shafts for respectively fixing the driven wheel 15 and the pressing wheel 21 are provided on the inner wall of the upper housing 12, so that the driven wheel 15 and the pressing wheel 21 are rotatably installed in the upper housing 12. When the upper housing 12 is closed on the lower housing 5, the adhesive tape is tightly pressed by the pressing wheel 21 and the driven wheel 15 together with the big roller 6, the small roller 9 and the rubber ring 10. The big roller 6, the rubber ring 10, the small roller 9 and the transportation wheel 11 form a lower passage for transporting the adhesive tape, and the driven wheel 15 and the pressing wheel 21 form an upper passage for transporting the adhesive tape. The adhesive tape is transported between the upper passage and the lower passage. An adhesive tape discharge opening of the lower housing 5 is provided with a serrate rib along a direction in which the adhesive tape goes out. The material of the rubber ring 10 is silicon rubber.

[0023] The operation principle of the present invention is given as follows. The upper housing 12 is opened, the adhesive tape is installed between the rubber ring 10 and the pressing wheel 21, and then the upper housing 12 is closed, so that the adhesive tape is tightly pressed by the pressing wheel 21, the driven wheel 15, the big roller 6, the small roller 9 and the rubber ring 10. The button 1 is pressed down, and the double linked gear 3 is rotated in the clockwise direction to move the rack 4 rearwardly, and then the reward moving rack 4 drives the one-way pawl 7 to rotate in the counter clockwise direction, so that the ratchet wheel assembly is rotated in one way, i.e. the counter clockwise direction. When the ratchet wheel assembly is rotated counter clockwise in one way, the rubber ring 10 is moved forwardly in one way, so that the adhesive tape pressed on the surface of the rubber ring 10 is automatically forwardly transported by a certain distance. During the rearward moving of the rack 4, the swaying wheel 8 is rotated forwardly, and drives the swaying rod 18 to rotate forwardly. When the swaying wheel 8 is rotated to a certain position, the swaying rod 18 is disengaged from the swaying wheel 8 and then is automatically returned by the torsion spring. During this process, the pressing rod 17 doesn't move because it is in the limit position. The button 1 is released, and then returned by the spring 2. When the button 1 is returned, the double linked gear 3 is rotated in counter clockwise direction, and the double linked gear 3 drives the rack 4 to move forwardly, and the forward moving rack 4 drives the swaying wheel 8 to swing backwardly, so as to push the swaying rod 18 to rotate backwardly, so that the pressing rod 17 is rotated downwardly. During the downward rotation of the pressing rod 17, the cutting seat 16 and the cutting blade assembly are pressed downwardly. The cutting seat 16 and the transportation wheel 11 firstly press the adhesive tape, and the cutting blade 13 cuts off the adhesive tape subsequently. When the swaying wheel 8 is moved to a certain position, the swaying wheel 8 is disengaged from the swaying rod 18, and under the action of the tension spring 20, the pressing rod 17 brings the cutting blade assembly, the cutting seat 16 and the swaying rod 18 to return. One operation of the adhesive tape dispenser is finished.

[0024] The present invention is not limited by the above preferred embodiment, and products in other forms may be made according to the enlightening given by the present invention. Any variation in shape or structure, which is the same as or similar to the technical solution of the present invention, falls into the protection scope of the present invention.
