Abstract
The present invention relates to a power tool with battery power supply comprising a main body and a detachable battery package which are connected with each other via a securing frame and a locking assembly. The securing frame includes a guiding device, an locking/unlocking button located on one of the main body and the battery package. An electrical connection is provided between a motor in the main body and the battery package, and includes a plurality of electrode connectors and corresponding electrode contact tabs. A mechanism for creating a non-mechanical force is located between the main body and the battery package for pushing the battery package out of the securing frame. With such a mechanism, when the battery package is required to be replaced by another one or detached for charging, it is merely necessary to press the unlocking button downward, and the battery package then automatically slides out of the securing frame via the effect of the force so as to facilitate detaching the battery package from the main body of the power tool.
