Abstract:
An automatic cutting device for an adhesive-tape holder including a handle and two side plates and comprising:a) an L-shaped blade holder connected between two side plates of a handle, the blade holder having: i) two fixing studs protruding upwardly; and ii) a center receiving groove; b) a blade having two first oval slide holes, the fixing studs of the blade holder being inserted into the first oval slide holes of the blade; c) an L-shaped blade slide base slidably connected to the blade holder, the blade slide base having: i) two second oval slide holes, the fixing studs of the blade holder being inserted into the second oval slide holes of the blade slide base; ii) a spring positioned between the center receiving groove in the blade holder and the blade slide base; and iii) a projecting stud inserted through the spring, wherein the blade slide base and blade are slidable between a retracted position and a cutting position; and d) an S-shaped press plate having two pivotal studs on opposing sides and a push plate on a first end thereof, each of the two pivotal studs pivotally connected to one of the two side plates, the push plate engaging the blade slide base, such that when a force is applied to the press plate on a second end opposite the push plate, the push plate compresses the spring and slides the blade slide base and blade into the cutting position, and when the force is removed from the press plate, the spring slides the blade slide base and blade into the retracted position.
