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.
