It should be noted that the inner wall of each splint 5 is against the outer wall of the discharge pipe 4, so that the fixing device can be fixedly connected to the discharge pipe 4.

[0026] Each limiting device includes a limiting groove 10 opened on the upper end surface of the clamping plate 5 and a movable groove 11 opened on the inner side wall of the clamping plate 5, and each movable groove 11 is connected to the limiting groove 10 at the corresponding position, and a spring 12 is fixedly connected in the movable groove 11, one end of the spring 12 is fixedly connected to a top block 13, and the top block 13 is slidably clamped in the movable groove 11, and one end of the top block 13 is clamped in the fixed hole 15 at the corresponding position, and a push plate 14 is fixedly installed on the outer wall of the top block 13, and the push plate 14 is slidably clamped in the limiting groove 10.
