<p>A toy pistol-drill comprises a body 1 to which is attached a part 3 having the appearance of a chuck. A drill bit 4 is axially movable in a sleeve 6 and is biased by a spring 5. The sleeve is movable into the housing so as to press a strip 7 against a toothed wheel 8, which is driven by an inertial mechanism 9 containing a flywheel which is spun by an automatically retracting pull-string 11. Contact of the strip 7 on the toothed wheel 8 produces a sound simulating a real drill. <IMAGE></p> |
