[0033] There are six damping springs 106 distributed on both sides of the steel ring 105 . The baffle 110 has a triangular shape on the side and a rectangular shape on the front.
[0034] The moving mechanism 2 includes a wheel rod 201, and the two ends of the outer wall of the wheel rod 201 that are far away from each other are rotatably connected to the pulley 202, and the two ends of the outer wall of the wheel rod 201 that are close to the pulley 202 are fixedly connected to the support plate 203, and the top of the support plate 203 is threadedly connected to the base 204, and the inner wall of the base 204 is provided with a threaded hole 205.
