[0028] The first air permeable groove 3 is connected with the second groove 4, the movable plate 5 is located inside the first groove 2, the first air permeable groove 3 and the second air permeable groove 6 are the same in size and shape, the movable block 8 is located inside the second groove 4, and the left outer wall surface of the device shell 1 is fixedly connected with a load-bearing plate 12, the load-bearing plate 12 can play a certain supporting role for the movable block 8, and the number of the load-bearing plates 12 is multiple.
