The outside of the stopper 12 is elastically connected to the middle inside of the U-shaped groove 3 through the spring 2 11, and the stopper 12 is squeezed by the spring 2 11 to maintain the state of sliding down. One end of the spring 2 11 is fixedly connected to the upper end of the U-shaped groove 3. The spring 2 11 is kept in the state of squeezing the stopper 12 by the U-shaped groove 3. The other end of the spring 2 11 is fixedly connected to the upper part of the stopper 12, and the stopper 12 A positioning block 13 is fixedly connected to the side end, and the positioning block 13 limits the block 12 to only slide relatively vertically.
