Abstract: A disk data destroyer comprises a housing, a data destroying shaft set, a motor driver and a sensor. The housing is provided with a hollow receiving chamber, a disk insertion slot and a disk outlet opposite said insertion slot. The sensor is mounted inside said housing adjacent to said disk insertion slot and adapted to output a driving signal to start said motor driver to drive the data destroying shaft set to rotate upon insertion of a data storage disk into said disk insertion slot such that the inserted disk is pressed by the data destroying shaft set so as to destroy storage data thereof.

Abstract: The present invention relates to a frame width adjusting structure of the paper shredder and is mounted on a paper shredder main body containing a paper shredding tool, a control circuit, and a drive motor. The main body is provided in one side with a retaining piece extending downwards. The frame width adjusting structure comprises two expandable rods parallel to each other and disposed in other side of the main body to be opposite to the retaining piece; a bridging member connecting the outer ends of the two expandable rods and having a receiving cell with an opening that faces downwards; two fixation pillars disposed at top end sin the top of the receiving cell of the bridging member; two connection rods pivoted with bottom ends of the two fixation pillars; a pull handle provided at the outer end with a retaining piece extending downwards and pivoted with other end of the two connection rods.

Abstract: A blade is designed for use in the paper shredder and is formed of a main body which is provided in the center thereof with a through hole for mounting the blade on a shaft rod. The main body is provided in the periphery thereof with one or more notches, blade edges, edge head ends, and edge tail ends. The main body is provided in the outer edge surface thereof with a plurality of cavities.

Abstract: A device is designed to shred paper and to sharpen pencil. The device comprises a housing, a paper-shredding tool, a drive apparatus, a link mechanism, a rotation mechanism, and a pencil sharpening tool. The housing is provided with a long hole and a through hole. The paper-shredding tool is mounted in the housing and is corresponding in location to the long hole of the housing. The drive apparatus is mounted in the housing to provide a driving force, which is transmitted via the link mechanism to the paper-shredding tool. The rotation mechanism is mounted in the housing and is connected with the link mechanism. The pencil-sharpening tool is disposed in the rotation mechanism to turn along with the rotation mechanism. The pencil-sharpening tool is corresponding in location to the through hole of the housing.

Abstract: A device is intended to monitor the paper shredding action of a paper shredder and composed of two paper guiding grid plates, a microswitch, and a detecting rod. A paper guiding passage is formed between the two grid plates. A first paper guiding grid plate is provided with a fastening seat. The detecting rod is fastened pivotally with the fastening seat such that the detecting rod extends between the two paper guiding grid plates. The microswitch is mounted on the fastening seat such that the microswitch is contiguous to the detecting rod. As the front end of a paper sheet has passed the paper guiding passage, the detecting rod is pushed by the front end of the paper sheet to swivel to trigger the microswitch to activate the shredding tools of the paper shredder.

Abstract: A paper feeding sensor mounted in the paper shredder is composed of a microswitch and a detection rod capable of triggering the microswitch so as to actuate two cutters of the paper shredder. The detection rod is received in a receiving cell of the paper guiding grid plate of the paper shredder such that the detection rod is pushed to trigger the microswitch by a paper which is fed into the receiving cell of the paper guiding grid plate.
