[0003] The Chinese patent with publication number CN216946202U discloses an oil station oil gas recovery detection auxiliary device. The auxiliary device clamps one end of the detection shell with a rubber ring to one end of the oil gun. When the oil gun back gas, the wind energy capture plate on the support ball will be unfolded, and the tension of the tension spring will be applied. The tension of the tension spring is measured by the tension force measuring instrument, and the tension is displayed on the display screen. If the tension is very low, the oil gun back gas will be weakened, and the alarm light will prompt. Multiple detection shells are installed in the box to detect the idle oil gun.
