Then, the first threaded rod 21 is threaded into the first threaded groove 2. The installation height of the limiting plate 24 is adjusted, and then the position of the limiting plate 24 is adjusted so that the arc-shaped block 26 on the limiting plate 24 is above the basic limiting position. The second threaded rod 25 is rotated so that the arc-shaped block 26 presses down on the positioning base plate to complete the fixing operation. When disassembling or adjusting the position, the limiting mechanism can be removed by directly rotating the first threaded rod 21. After the limiting plate 24 is adjusted to the required position, the positioning pin 28 passes through the limiting plate 24 and is then inserted into the positioning hole 27 to limit and fix the entire limiting plate 24 to ensure basic stability.
