At this time, the screw is taken out of the threaded hole to facilitate disassembly.

However, before adjusting the height of the anti-fall plate, the position of the anti-fall plate needs to be adjusted in advance, and it needs to be adjusted back and forth during use so that the anti-fall plate can be in the correct position, which makes the operation process more cumbersome and the operation process longer.
