Carrier

A carrier, comprising:

• a frame body;
• a carrying device, detachably mounted on the frame body;
• a locking mechanism, movably provided on one of the frame body and the carrying device, and switchable between a locked state and an unlocked state, wherein the locking mechanism locks the frame body and the carrying device when the locking mechanism is in the locked state, and the carrying device is capable of separating from the frame body when the locking mechanism is in the unlocked state;
• and
• a holding mechanism, movably provided on one of the carrying device and the frame body and having a first avoidance state and a holding state, wherein when the carrying device and the frame body are connected to each other, the holding mechanism is located between the locking mechanism and the other one of the carrying device and the frame body;
• wherein, when the carrying device and the frame body are connected to each other and the locking mechanism is in the locked state, the holding mechanism deviates from a moving path of the locking mechanism, the holding mechanism is in the first avoidance state, and the locking mechanism is capable of switching from the locked state to the unlocked state relative to the holding mechanism;
• when the carrying device and the frame body are connected to each other and the locking mechanism is in the unlocked state, the holding mechanism is located on the moving path of the locking mechanism, the holding mechanism is in the holding state, and the holding mechanism maintains the locking mechanism in the unlocked state.
