The outer surface of the 3 is provided with an arc-shaped groove 14, and the upper surface of the adjusting plate 13 is provided with a slot 19. The number of slots 19 is 9 U-shaped clamps arranged in a circular array to prevent the rotation of the rotating shaft 5. The outer surface of the gas pipe 3 is fixedly connected to the sealing gasket 2 to facilitate the introduction of gas into the oil storage tank. The outer surface of the rotating shaft 5 is rotatably connected to the fixed plate 1. The inner surface of the slide groove 6 is adapted to the slider 8. The number of U-shaped clamps 9 is 4 and arranged in a circular array. The contact block 10 is made of rubber and the outer surface of the contact block 10 is provided with anti-slip texture to improve the stability of the device after installation. The inner surface of the arc-shaped groove 14 is adapted to the limiting post 11 to limit the movement of the limiting post 11. The lower surface of the limiting disc 12 is in contact with the adjusting plate 13 to limit the adjusting plate 13.

[0021] A square plate 15 is fixedly connected to the upper end of the rotating shaft 5. A spring 16 is provided on the outer surface of the rotating shaft 5. A hexagonal rotating block 17 is slidably connected to the outer surface of the rotating shaft 5. An insert block 18 is fixedly connected to the lower surface of the hexagonal rotating block 17.

[0022] Working principle: During operation, the fixed plate 1 is placed over the oil filling pipe opening on the oil storage tank, and the fixed plate 1 is pressed down to force the sealing gasket 2 into close contact with the oil filling port of the oil storage tank. Then, the fixed plate 1 is pressed down to temporarily limit its position, and the hexagonal rotating block 17 is pulled upward to force the insert block 18 to disengage from the slot 19 under the limiting action of the square plate 15, and to compress the spring 16. Then, the hexagonal rotating block 17 is rotated to drive the rotating shaft 5 to drive the adjusting plate 13 to rotate. Then, under the limiting action of the arc groove 14, the limiting post 11 and the limiting disc 12, the U-shaped clamping frame 9, the slider 8, and the contact block 10 slide along the inside of the sliding groove 6. The rod 7 slides to clamp four points on the outer surface of the oil filling pipe of the oil storage tank, thereby fixing the entire device at the oil filling pipe. Then, the hexagonal rotating block 17 is released. Under the action of the spring 16, the insert block 18 will be inserted into the corresponding slot 19, thereby limiting the rotating shaft 5 to prevent loosening and improving the stability of the entire device after installation. After the entire device is fixed, the air pipe 3 is connected to the air pump, and air is injected into the oil storage tank. After maintaining the rated air pressure for a period of time, the pressure gauge on the air pump is observed. If there is no significant change in air pressure, it indicates that the oil storage tank has good sealing performance; otherwise, it indicates that the oil storage tank has poor sealing performance.
