Abstract
A multipurpose combination tool comprises a main body portion with a motor and drive shaft, and an interchangeable tool head portion that can be removably coupled to the main body portion through a locking mechanism and power transmission device for transmitting power from the main body portion to the tool head portion. The locking mechanism includes a thrust ring, a locking ring and a locking pad operably associated with the main body portion and a locking head operably associated with the tool head portion. The power transmission device comprises an internal spline on the main body portion that meshes with an external spline on the tool head portion. In this manner, the tool head portion associated with one task, such as drilling, can be changed for other tool head functions associated with other tasks, such as sanding, grinding, mixing, sawing, and so on to thereby provide multiple tasking with one machine.
