[0028] Working principle: Since the cable retracting mechanism in the prior art mainly winds the cable around the spool for retracting when working, and when multiple cables are retracted, it is easy to get tangled, so it is necessary to organize these cables at all times when retracting, resulting in the problem of low efficiency in retracting and releasing multiple cables at the same time.
