Abstract: The present disclosure relates to a quick-install structure for an electrical device, including a base and a module. The base is provided with at least two gripping slots. The module is detachably installed on the base. The module is provided with at least two gripping hooks, and the gripping hooks are in one-to-one correspondence with the gripping slots. When the gripping hooks are inserted in the gripping slots, the module has a first position and a second position relative to the base. When in the first position, the gripping books grip with the gripping slots tightly. When in the second position, the gripping hooks are detached from the tight gripping with the gripping slots. The module is switchable between the first position and the second position.
