During the use, through rotating first nut 6 to offset with the outside of first curb plate 2 and second curb plate 12 respectively through first nut 6, thereby can adjust and spacing the position of first curb plate 2 and second curb plate 12.
It should be noted that the threaded rod 5 and the first side plate 2 and the second side plate 12 do not need to be connected by threads, and only the first side plate 2 and the second side plate 12 can be ensured to move on the threaded rod 5. In order to reduce wear of the first nut 6 and the first and second side plates 2, 12, rubber gaskets may be provided between the first nut 6 and the first and second side plates 2, 12.
In other embodiments, the threaded rod 5 and the first nut 6 may be straight rods that are not threaded, and a clamp is disposed on the straight rods, so that the position of the first side plate 2 and the second side plate 12 is limited by the position of the clamp.
