Powered hand-held tool with unitary sub-assembly mounted by the tool housing sections |
摘要 |
A cordless electric drill has a housing formed by two clam-shell sections secured together by a plurality of fasteners. These housing sections define a closed motor and gear compartment which receives a sub-assembly, the latter including a generally U-shaped gear box frame mounting a small D.C. electric motor, a plurality of reduction gears and a spindle. A drill chuck is mounted on the spindle. The sub-assembly and the housing sections include co-operating mounting formations, defined in part by projections and cavities, which mounting formations serve to mount the sub-assembly in place in response to securing the clam-shell housing sections together by the aforesaid fasteners.
