How to reduce the telescopic rod of the upper suspender

The method is simple. First, we need to find the fastening screw at the joint of the telescopic rod, and then we only need to loosen this fastening screw to recover the telescopic rod.

Of course, if the telescopic rod cannot be retracted after being loosened, it is likely that the parts have been rusted for too long to be used normally. At this time, we can drop a few drops of lubricating oil on the node, let it stand for a few minutes and then try to retract.

If it really doesn't work, you can only find a professional to repair and replace it.
