Patent attributes
A battery retention system for a power tool having a motor, a drive mechanism coupled to the motor, an output element coupled to the drive mechanism, and latch-receiving recesses for receiving battery pack latches. The battery retention system includes a battery pack for powering the motor. The battery pack is removably coupled to the power tool and includes latches and elongated rails. The system includes a cavity in the power tool for receiving the battery pack in a direction of insertion. Spring arms extend generally in the direction of insertion and each have a projection extending into the cavity for coupling the battery pack to the power tool. The spring arms are configured to deform in engagement with the respective rails of the battery pack when the battery pack is inserted into the cavity. The rails are elongated generally in the direction of insertion.
