The outer surface of the vertical part of the L-shaped positioning ring 33 is rotatably connected with a rotating ring 32, the upper end of the rotating ring 32 is fixedly installed with four screw rods, the four screw rods are arranged in a ring array, and the upper part of the screw rod penetrates through the top wall of the inverted L-shaped mounting ring 31 and is threadedly connected with a nut;

[0029] Therefore, during initial installation, the elbow connecting pipe 2 and the tower joint 4 are tightly connected by the screw rod and the nut, but due to the rotatable connection between the rotating ring 32 and the L-shaped positioning ring 33, the tower joint 4 and the L-shaped positioning ring 33 can also be relatively rotated with the elbow connecting pipe 2 and the inverted L-shaped mounting ring 31 by dragging the rubber pipe.

[0030] Specifically, as shown in Figure 3 and Figure 4 , the inner surface of the vertical part of the L-shaped positioning ring 33 is provided with a plurality of grooves 35, the bottoms of the plurality of grooves 35 extend to the inner side of the horizontal part of the L-shaped positioning ring 33 and jointly form a ring-shaped groove 36, the lower end of the L-shaped positioning ring 33 is fixedly installed with a liquid storage bag 37 and a protection tube 38, the liquid storage bag 37 is located inside the protection tube 38, so as to avoid the liquid storage bag 37 from being exposed to the sun for a long time, causing aging and damage, and the liquid storage bag 37 is in communication with the ring-shaped groove 36;

[0031] In addition, in the initial state, the liquid storage bag 37 is in a contracted state, so as to facilitate subsequent collection of oil, and can extend out of the shielding range of the protection tube 38;
