A force-limiting and damping device has a body, a tapping element, and an elastic element. The body has a connecting segment and a holding segment. The connecting segment is formed on an end of the body and has a mounting hole. The holding segment is formed on the body opposite the connecting segment. The tapping element is connected to the body to move relative to the connecting segment. The elastic element is mounted between the tapping element and the connecting segment to abut against the tapping element and to enable the tapping element to move relative to the connecting segment. The structural relationship between the connecting segment, the tapping element, and the elastic element may provide a delayed rebound and damping effect to the reaction force, and the applied force is continuously transferred to a tapping object. This may reduce noise and the loss of energy.
