The invention discloses a paper shredder facilitating discharging, and relates to the technical field of office equipment. The paper shredder comprises a shell and a crushing bin, wherein the two sides of the crushing bin are fixedly connected with the two surfaces of the inner cavity of the shell, the top of the inner cavity of the shell is fixedly connected with a motor, an output shaft of the motor is fixedly connected with a crushing shaft, a feeding motor is fixedly connected to one side of the top of the inner cavity of the shell, a first rotating wheel is fixedly connected to an outputshaft of the feeding motor, the surface of the first rotating wheel is in transmission connection with a second rotating wheel through a chain, one side of the second rotating wheel is fixedly connected with a rolling wheel, and the left side of the inner cavity of the shell and the bottom of the rolling wheel are fixedly connected with a feeding plate. The feeding motor works to drive the rollingwheel to rotate, paper is conveyed into the crushing bin, the gear is driven to rotate through the working of a discharging motor, and a movable plate is driven to move through the mutual movement ofthe gear and a toothed plate, so that a discharging box is conveyed out of the shell, the working efficiency is improved, and the use is convenient.
