  • Publication number: 20190323657
    Abstract: A connection device for connecting a first to-be-connected device and a second to-be-connected device includes a first connection member configured to connect with the first to-be-connected device. The first connection member includes a snap-fit groove. The connection device also includes a second connection member configured to connect with the second to-be-connected device. The second connection member includes a snap-fit hook configured to couple with the snap-fit groove to limit a relative motion between the first connection member and the second connection member.
