• a snap-fit assembly comprising a mounting seat, a snap-fit member, and an elastic reset member;
• wherein the mounting seat defines an accommodating cavity and a first opening, the first opening extends through a side wall of the mounting seat in a first direction and is in communication with the accommodating cavity, and the mounting seat is configured to connect the fastened body;
• the snap-fit member is slidably mounted in the accommodating cavity in the first direction, and the snap-fit member is able to slide between a first position and a second position in the first direction;
• the snap-fit member comprises a snap-fit portion, and the snap-fit portion is opposite to the first opening in the first direction;
• the elastic reset member is connected between the mounting seat and the snap-fit member, and the elastic reset member is configured to provide the snap-fit portion with an elastic force against the first opening;
• and
• a connector comprising a clamping portion and a connecting portion, wherein the clamping portion is connected to the connecting portion, and the connecting portion is configured to connect the fastening body;
• wherein when the snap-fit member is in the first position, the snap-fit portion is away from the first opening, and the clamping portion is operable to be inserted into the accommodating cavity through the first opening;
• and
• wherein when the snap-fit member is in the second position, the snap-fit portion is adjacent to the first opening and restricts the clamping portion to separate from the accommodating cavity through the first opening.
