Abstract
A toy power tool is disclosed which includes the provision of an external housing in the shape of a power tool including a handle portion for grasping by the user. A sounding device is mounted within the housing and produces an audible signal simulating the sound of a power tool. The sounding device includes a flywheel, pullstring, and a wafer-type leaf spring movable into engagement with a sounding gear to produce the audible sounds. A blade guard is biased by a spring outwardly with respect to the housing so that as the housing is placed in engagement with a work piece and moved relative thereto, the blade guard moves into the housing. A cam on the blade guard engages a wafer and moves it into contact with the sounding gear to cause an audible signal to be produced.
