Abstract: An auto electricity breaker includes a breaker switch, an energy storage device driven by a cutting blade ensemble, a variable gear set driven by the energy storage device, a trigger driven by the variable gear set to turn on the breaker switch, and a starting switch for restoring the trigger. The energy storage device stores energy concurrently during the operation of the cutting blade ensemble. When the cutting blade ensemble stops operation, the variable gear set is driven to operate. When the variable gear set operates to a certain extent, the trigger takes action to turn on the breaker switch. The breaker switch breaks the electrical power of the shredder to stop its operation. The user can turn on the starting switch for restoring the trigger and thus turn on the power of the shredder again for normal operation. The breaker then resumes its auto electricity breaker function.

Abstract: A control mechanism for the feed of a brush chipper is disclosed. A lower feed stop bar, located under a feed table, pivots on a pivot axis located below and toward the brush chipper from the control bar of the lower feed stop bar. The center of gravity of the lower feed stop bar, then, tends to pivot the lower feed stop bar away from the feed disengage position. Hence, nuisance trips due to vibration, impact of brush on the table, etc., are reduced.

Abstract: This specification discloses a variable protection board that can change the width of the opening of a paper shredder. A sliding block is disposed on one side of the paper shredder opening to change the relative position between the sliding block and the opening.
