ABSTRACT:
An adhesive tape roller fixing device for an adhesive tape dispenser includes a pivotal shaft fixed sidewise on a sidewall of the dispenser body, and a small roller, a guide roller and a blade orderly fixed at the front portion of the sidewall. The pivotal shaft has a cylindrical body, two lengthwise slots formed spaced apart in the cylindrical body to define two elastic section walls, and a one-way constrict wall extending out from the outer surface of the cylindrical body on an irregular section wall of the cylindrical body. Then when an adhesive tape roll is fitted around on the pivotal shaft, two hooks of the two elastic section walls stop the outer end of the adhesive tape roll and keep it from falling off. Further, the one-way constrict wall elastically pushes outward tightly the adhesive tape roll to let it rotate only forward, never backward.
