Mechanical delaying device of shredder
A mechanical delaying device of a shredder includes a lever connected with a spindle at frames of blade assemblies, a roller accommodated around a shaft at an end of the lever, a baffle fastened at an end of the shaft, a spring disposed between the roller and the baffle, and a helical cam disposed at an outer side of a fixing plate of one of the blade assemblies. When paper is not inserted, the roller presses against the spring and blocks at an outer end of the cam. When paper is inserted, paper is pressed downward for driving and rotating the spindle such that the roller is displaced outward from the cam. A restoring force of the spring pushes the roller inward. The roller follows the cam as the cam is rotated by the blade assemblies, driving the roller to an outermost end of the cam, thereby accomplishing delaying and halting purposes.
