The utility model relates to a fixing mechanism for climbing equipment and a fixed matching mechanism for the climbing equipment and a wall-attached seat. The fixing mechanism for the climbing equipment comprises a box body and a support body, wherein a support claw is arranged at one end of the support body, and is exposed from the box body; a stress part is arranged at the other end of the support body; in an initial state, the support claw is horizontally arranged, and the stress part is downwards stressed, and cannot downwards move under the limitation of the box body. According to the fixing mechanism for the climbing equipment and the fixed matching mechanism for the climbing equipment and the wall-attached seat, the support body can rotate around a rotating shaft, and when the climbing equipment upwards moves, the support claw cannot be limited by a lug boss of the wall-attached seat; the support claw is positioned on one side of the rotating shaft, and is automatically reset to the initial state when crossing the lug boss of the wall-attached seat under the action of downward stress on the stress part; when the lower end of the support claw is supported on the lug boss of the wall-attached seat, the support body is limited by the box body, so that the climbing equipment can be suspended on the lug boss of the wall-attached seat.
