[0032] A closed mother ring 411 is connected below the four first connecting rods 413, one end of the first connecting rod 413 is connected to the second connecting rod 417 through a spring hinge 418, a closed disk 415 is connected below the four second connecting rods 417, the other end of the second connecting rod 417 is connected to a sleeve rod 410, and a vertical rod 49 is connected to the sleeve rod 410. The power generated by the oil unloading pump and the oil delivery pump can be used to open the pipe mouth opener 4, without manual operation, which is convenient for closing the vertical pipe 3 after pumping oil and avoiding residual oil dripping and polluting the environment.

[0033] See also Figure 3 , Figure 4 , Figure 5 A guide frame 45 is sleeved on the vertical rod 49, and a guide groove 44 matching the vertical rod 49 is opened in the guide frame 45. Four guide blocks 416 are installed above the rod body of the vertical rod 49 at equal distances along the circumference.

[0034] A second slide groove 422 for the guide block 416 to slide is defined in the guide groove 44 . A second limit block 424 is disposed at the bottom of the second slide groove 422 . A slide column 423 is disposed on the second limit block 424 . The slide column 423 penetrates the guide block 416 and is slidably connected to the guide block 416 .

[0035] First slide grooves 46 are provided on both sides of the outer wall of the guide frame 45, and a first limit block 48 is installed at the bottom end of the first slide groove 46. A slide rod 47 is slidably connected in the first slide groove 46, and the other end of the slide rod 47 is fixedly connected to the inner wall of the vertical pipe 3. The vertical pipe 3 can be opened manually to realize the recovery of residual oil, which is more beneficial to environmental protection. In addition, the use of an independent guide frame 45 structure will not affect the automatic opening and closing of the pipe mouth opener 4, which is more practical and convenient.

[0036] See also Figure 4A rack 43 is also provided on the outer side of the guide frame 45, and a gear 42 is meshed on the rack 43. A wheel rod 420 is connected to the axis of the gear 42.
