Abstract
An electric tool () allowing an external battery pack () to detachably connect thereto is disclosed. The electric tool () includes a housing and a motor () installed in the housing, and in addition the electric tool () includes a supporting part fixedly coupled to the housing; and a terminal holder (). The terminal holder () is adapted to contact with terminals on an external battery pack () in order to form a consistent electrical connection. The terminal holder () is confined by the supporting member () and in the meantime adapted to move relative to the supporting part. The terminal holder () has a hollow shape and is adapted to contact with the support member () at an exterior surface of the terminal holder (). As the terminal holder () is tightly fitted with the battery pack () but at the same time loosely fitted with the tool housing, chances of generating sparks or electric arc between the metal terminals can be minimized.
