The fixed base 1 has several positioning grooves 2 evenly distributed horizontally in the middle of its upper surface. A buffer device 3 is inserted into the center of each positioning groove 2. Telescopic brackets 4 are symmetrically connected to the outer edges of the upper surface of each positioning groove 2. A locking screw is inserted into the middle of the rear surface of the right telescopic bracket 4.

A fixing post 7 is connected to the middle of the rear surface of the clamping device 6. The buffer device 3 includes a support plate 3-1, a rubber pad 3-2, rubber posts 3-3, and a spring 3-4. The rubber pad 3-2 is connected to the lower inner surface of the support plate 3-1. Several rubber posts 3-3 are evenly distributed around the outer surface of the support plate 3-1. A spring 3-4 is connected to the center of the lower surface of the support plate 3-1. The support plate 3-1 is hemispherical in shape. The support plate 3-1 is inserted into the positioning groove 2, and the lower end of the spring 3-4 is connected to the inside of the positioning groove 2. The telescopic bracket 4 includes a lower plate 4-1, a tension spring 4-2, an insert plate 4-3, and a threaded hole 4-4. The tension spring 4-2 is connected to the middle of the lower inner surface of the lower plate 4-1, and the insert plate 4-3 is inserted into the middle of the upper surface of the lower plate 4-1.
