A return spring 21 is fixedly connected to the bottom surface of one of the fixed blocks 18, and one end of the return spring 21 is in contact with the outer surface of the sealing ball 20. The docking screw sleeve 22 is used to connect the docking tube 4 and the feed pipe 5. By setting the hollow stopper 19, a continuous thrust can be applied to the sealing ball 20 during the docking process, so that the feed pipe 5 is connected, and there is sufficient clearance when the sealing ball 20 is inside the fixed block 18.

[0021] like Figure 2 and Figure 3 As shown, a sealing ring 6 is fixedly connected to the inside of the butt joint 4, an adjusting cover 7 is slidably connected to the inside of the sealing ring 6, a plurality of feed through holes 8 of different lengths are connected through the outer surface of the adjusting cover 7, an adjusting rack 9 is fixedly connected to one end of the adjusting cover 7, an adjusting gear 10 is engaged with the outer surface of the adjusting rack 9, and an adjusting rod 11 is fixedly connected to the inside of the adjusting gear 10. By setting the sealing ring 6, the adjusting cover 7 can be divided into two parts on the sealing ring 6, and then the effective gap size of the feed through hole 8 on the adjusting cover 7 can be controlled. By setting the adjusting gear 10, the adjusting rack 9 can be driven to move, and then the position of the adjusting cover 7 can be adjusted.
