发明名称 Alarmed chuck wrench
摘要 A novel safety-equipped chuck wrench is provided, as well as a method for using the same. The safety-equipped chuck wrench comprises a chuck wrench and a safety device associated with the chuck wrench, where the safety device comprises an alarm, a power source and an alarm activation switch. The alarm activation switch causes the alarm to activate so long as the chuck wrench is engaged in a chuck, subject to de-activation by engagement of a cut-off switch, if any. The alarm may be an audible alarm, a visual alarm, or both. The safety-equipped chuck wrench may include a mechanism for temporarily disabling the alarm, preferably through the use of a cutoff switch.
