The damping component 2 is internally provided with a cavity, the inner cavity surface of the damping component adopts parabolic design and is formed by connecting four convex-concave curves, and as shown in figure 3, the sliding throwing block 3 is attached to the inner cavity surface of the damping component 2.
In the invention, the damping member 2 is internally provided with a cavity, the inner cavity surface of the damping member 2 adopts parabolic design, and the sliding throwing block 3 is attached to the inner cavity surface of the damping member 2. The sliding throwing block 3 moves in the cavity in the damping member 2 along with the falling process of the invention, and the sliding throwing block 3 is attached to the inner cavity surface of the damping member 2 along with the cavity action in the throwing block mounting frame 10 during the rotation process of the throwing block mounting frame 10 along with the falling of the damper.
