<p>An AC, DC interchangeable multipurpose combination power tool system, characterized in that a main body (1) of AC power tool and a main body (5) of DC power tool are combined with a variety of tool heads (4) in interchangeable way. The combination is accomplished via an outer spline (2) arranged on the main body (1,5) and an inner spline (3) arranged on the tool head (4). The main body (1,5) is provided with locking mechanism (6) to tightly lock up the tool head (4) to the main body (1,5). The combination power tool system can be widely applied at working sites whether power supply network is available or not, and can satisfy different working requirements. <IMAGE> <IMAGE></p> |
