[0027] Among them, the limiting rod 21 passes through the sliding block 10 to guide and limit the sliding block 10 to prevent the sliding block 10 from detaching. When the track wheel 6 vibrates, the sliding plate 4 slides up and down in the fixed frame 3, and the sliding plate 4 can drive the guide block 24 to slide in the guide groove 25.
