Abstract
An automatic cutting device for an adhesive-tape holder includes a handle, a blade holder, a blade and a press plate. The blade holder is provided with two fixing studs and a receiving groove. The blade has two oval holes fitted around the fixing studs of the blade holder. The blade slide base is mounted on the blade to activate the blade to move forward, and provided with two oval holes, a projecting stud and a spring. The press plate is formed with a push plate at the lower end for pushing the blade slide base. The blade is sandwiched between the blade slide base and the blade holder to be guided and restricted in shifting, so that it can automatically cut off an adhesive tape with precision when the press plate is pressed.
