Easily releasable locking device for detachably securing a battery pack to a portable battery-powered apparatus

摘要

An easily releasable locking device includes upper and lower assemblies of latch and cavity members adapted to be disposed between a right lateral wall of a battery pack and a right inner side wall of a bottom wall of a portable battery-powered apparatus respectively, and aligned with each other and spaced apart in a transverse direction. The latch member and the cavity member of each assembly are disposed on the right inner side wall and the right lateral wall, respectively. The latch members are biased by two biasing members to be movable towards the corresponding cavity members. Two ejecting members are disposed between the right lateral wall and the right inner side wall, respectively. Each ejecting member is disposed along the transverse direction and is actuated in response to a manual movement which is against the biasing action of a respective biasing member to lift the right lateral wall of the battery pack to move away from the right inner side wall of the bottom wall of the portable battery-powered apparatus and out of a major surface of the bottom wall so as to rotate a left lateral wall of the battery pack, thereby facilitating removal of the battery pack from the portable battery-powered apparatus.
