[0027] The buffer mechanism 3 is arranged on the support frame 21. The buffer mechanism 3 includes a fixed groove 31. There are three fixed grooves 31 and they are respectively opened on the right side of the support frame 21. A moving block 32 is slidably contacted on the inner wall of the fixed groove 31. A rubber ball 33 is fixedly connected to the side of the moving block 32 close to the valve plate 24.
