The liquid-phase sensor 21 is electrically connected to an indicator light 30, and the indicator light 30 is installed on the frame body 10;

[0027] After the liquid-phase joint 70 is inserted into the liquid-phase returning joint 20, when the liquid-phase sensor 21 detects the liquid-phase joint 70, the liquid-phase sensor 21 feeds back a signal to the indicator light 30, and the indicator light 30 lights up.

[0028] For the above-provided single-liquid-phase fluid loading and unloading arm returning device, the frame body 10 can be used for the liquid-phase joint 70 to be inserted and positioned through the liquid-phase returning joint 20, reducing the space and increasing the space utilization rate. The liquid-phase returning joint 20 uses the liquid-phase sensor 21 to detect whether the liquid-phase joint 70 is inserted in place. The liquid-phase sensor 21 reminds the staff through the indicator light 30, making the operation more convenient and the returning more effortless, and solving the problem that the liquid-phase joint 70 is prone to cause safety accidents due to random rotation and collision.
