摘要： A power tool with a metal housing (12) has motor (20) positioned within the housing (12). An output (22), positioned within the housing (12), is coupled with the motor (20) and is adapted to drive a tool. An activation member (26) is coupled with the motor (20). A battery pack (30) is electrically coupled with the activation member (26). The activation member (26) energizes and deenergizes the motor (20), which in turn, drives the output (22).

摘要： A power tool has a mechanism for ejecting a battery pack which includes a receiving frame which defines a cavity to receive a battery pack. A receiving member is adjacent the cavity. The receiving member meshes with a member on the battery pack to hold the battery pack in the cavity. A biasing member is in the cavity adjacent the receiving member. The biasing member ejects the battery pack from the ejecting mechanism. A member retains the biasing member in the cavity. The member guides a portion of the battery pack meshing with the receiving member into contact with the biasing member such that when the battery pack is locked onto the frame, the biasing member is in a compressed condition and when the battery pack is an unlocked position, the biasing member ejects the battery pack from the frame.
