When the first connecting pipe rotates, the limiting protrusion is matched with the groove matched with the limiting protrusion to limit the shaft pipe, and the shaft pipe is prevented from rotating, so that the relative position of the shaft pipe and the second connecting pipe cannot change, and therefore, only the first connecting pipe and the shaft pipe change in position.

In order to discharge water during rotation, the water outlet hole on the shaft tube comprises a first auxiliary water outlet hole and a second auxiliary water outlet hole; the first connecting pipe can rotate around the shaft pipe in a range between the first auxiliary water outlet hole and the second auxiliary water outlet hole. When the first connecting pipe rotates, only the first connecting pipe and the shaft pipe are subjected to position change, more specifically, the water outlet on the first connecting pipe and the water outlet on the shaft pipe are subjected to position change, and the rotation range of the first connecting pipe is between the first auxiliary water outlet and the second auxiliary water outlet, so that no matter how the first connecting pipe rotates, the water outlet of the first connecting pipe can be ensured to be in the range of the water outlet on the shaft pipe, and the water outlet effect is ensured.

In order to prevent the connecting pipe infiltration, be equipped with the bulge loop of many rings on its outer wall of central siphon, be equipped with waterproof rubber ring between the bulge loop cover. The arrangement of the multi-layer waterproof rubber ring can increase the tightness of the first fixing ring and the second fixing ring.

In order to increase the water inflow, one side of the shaft tube facing the first connecting tube is provided with a backflow hole, and the backflow hole and the water inflow hole are arranged at two ends of the same backflow path formed by the two convex rings. When the waterway is connected, water enters the shaft tube from the water inlet on the second connecting tube, and a part of water enters the shaft tube through the reflux path and the reflux hole, so that the structural arrangement clearly increases the water inflow.

In order not to weaken the jet speed when the water flows out, the water outlet holes are arranged on the convex ring. The water outlet is directly arranged on the convex ring, and no cavity formed by the convex ring and the fixed ring is arranged on two sides of the water outlet, so that water flow can not be dispersed, and the water body injection speed from the water outlet can be ensured.

Compared with the prior art, the structure is greatly simplified, the water inflow is increased through the arrangement that the water inlets in the two fixing rings, the backflow holes in the shaft tube and the whole shaft tube can be communicated with water, and the first connecting tube, the second connecting tube and the shaft tube can realize the function of stepless angle adjustment, so that the structure is simple, the cost is lower, and in sum, the structure has reasonable design and convenient assembly.
