A power supply apparatus for an electric bottle opener is used to open a bottle sealed with a cork. The electric bottle opener comprises a shell body (100), a worm (200), and a driving apparatus (300) fixed on the shell body and electrically connected to a power supply apparatus (400). The driving apparatus fits and is connected to the worm and drives the worm. The power supply apparatus comprises a battery (410), a battery case (420) disposed inside the shell body, and a battery cover (430) used to close the battery case. An end of the battery cover is connected to the shell body by using a pin shaft (431), and a fastener (451) fastened to the shell body is disposed at the other end of the battery cover. The power supply apparatus further comprises a retractable mechanism that controls the fastener to retract. The retractable mechanism controls the fastener to retract, so that the battery cover is conveniently closed, and the fastener can be prevented from damages. |
