[0012] Beneficial Effects

[0013] The utility model provides a combined rotary joint mechanism, which has the following beneficial effects:

[0014] (1) A combined rotary joint mechanism. During use, the utility model inserts the mobile infusion inner tube into the interior of the rotating core shaft, and then manually rotates the limiting sleeve in the forward direction, and the movable sleeve starts to rotate in the forward direction. Since the movable sleeve and the fixed sleeve are threadedly connected, the limiting sleeve starts to rotate downward, and the lower side wall of the limiting sleeve contacts the inclined surfaces of the multiple connecting sliders. The multiple connecting sliders are forced to move in a direction away from the limiting sleeve, and the multiple moving slide bars move in a direction close to the mobile infusion inner tube. Finally, the multiple moving slide bars clamp the mobile infusion inner tube. The entire process only requires rotating the limiting sleeve, which is easy and convenient to operate, and the multiple moving slide bars move synchronously, thereby improving the anti-eccentricity effect.

[0015] (2) This combined rotary joint mechanism, during the use of the utility model, by rotating the connecting pipe, according to the different rotation directions, the fixed adjustment block can be moved closer to the inside of the injection pipe, or the fixed adjustment block can be moved away from the inside of the injection pipe, so that the distance between the outer wall of the fixed adjustment block and the inner wall of the injection pipe can be changed, thereby adjusting the water intake. The sealing effect can be increased by the anti-seepage pad. When the multiple moving slide bars approach the movable infusion inner tube, the multiple fixed blocks will also approach the outer wall of the movable infusion inner tube, and finally the multiple fixed blocks will clamp it. Since the multiple fixed blocks are located in a spherical shape, the resistance of the movable infusion inner tube in the process of being stuck into the rotating core shaft 2 and the resistance of the movable slide bar 8 can be reduced, thereby facilitating the connection operation of the movable infusion inner tube.
