The theory of operation of above-mentioned watering device that this embodiment provided does: the device is fixedly arranged on a construction site, for example, the water inlet pipeline 4, the gear block 12 and the like are fixed on a mounting frame (not shown in the figure), when the device is used, the locking ring 5 is adjusted to a proper position, the pipe section of the water outlet pipeline 2 extending out of the through hole 301 is rotated, the rotation flexibility of the pipe section is checked, the pipe section cannot be loosened or tightened too much, the water outlet pipeline 2 is rotated to swing to a preset angle along the through hole 301 according to the position shown in figure 1, in the swinging process, the attaching part 7 is always in sealing contact with the inner wall of the sleeve 3, the through hole 301 is blocked, the leakage in the swinging process is avoided, and the water entering the sleeve 3 flows into the water outlet pipeline 2 through the water inlet of the water outlet pipeline 2, so that the water is sprayed. The jointing part 7 sleeved at the water inlet end of the water outlet pipeline 2 enables the water outlet pipeline to be sealed from a plurality of preset positions from the swing angle, so that the function of changing the spraying angle of the water spraying head 1 on the water outlet pipeline 2 is simply and effectively realized, the work is flexible, and water is sprayed more fully and reasonably. When the pull rope 9 pulls the water outlet pipeline 2 to rotate, the gear adjusting effect is achieved, the adjusting rod 11 can be fixed when sliding to each preset gear along the wavy gear sliding groove 1201, and therefore the angle of the water outlet pipe is fixedly arranged, and smooth gear shifting is facilitated due to the shape of the wavy gear sliding groove 1201. When the adjusting rod 11 is fixed, one of the jacks 13 is firstly pressed into the side wall for a certain length, so that the movable contact is separated from the fixed contact, the electromagnet 17 releases the other jack 20 to jack the adjusting rod 11, and the adjusting rod 11 is clamped in the recess at the corner of the corresponding gear sliding groove 1201 together with the top end of the other jack 13 still extending out, when the gear shifting needs to be carried out again, the adjusting rod 11 is manually shifted to extrude the second spring 18, so that the other jack 20 retracts for a certain distance, so that the adjusting rod 11 is released, when the adjusting rod 11 begins to be separated from the recess at the corner, one jack 13 is gradually released, finally, the movable contact 21 and the fixed contact 23 are contacted and conducted again at the corner, the electromagnet 17 attracts the other jack 20 to completely allow the adjusting rod 11 to pass through, and the adjusting rod is completely separated from. Accordingly, when the adjusting lever returns to the recess at the corner and touches one of the top posts 13, the electromagnet 17 is turned off again, and the other top post 20 is ejected to be clamped with the adjusting lever 11 together with the one top post 13. For convenience of use, the angle of the water outlet pipe 2 is adjusted before water is sprayed, and the user can select the angle to use.

Further, the sprinkler in the above embodiment may be further designed as follows: the sprinkler head 1 of the embodiment is made into a fan shape and is provided with a plurality of sprinkler heads 1, all sprinkler heads 1 are annularly surrounded into a circular disc-shaped body, the spraying openings of the sprinkler heads 1 are uniformly outward, two pipelines which are connected with each other and are positioned in the same diameter direction are opposite to each other, namely, water feeding pipes 24 which are formed by communicating respective water inlet pipes 4 and water outlet pipes 2 are arranged along the circle center direction of the disc-shaped body and are opposite to each other, so that all the water feeding pipes 24 are in a circular array by taking the circle center as the center, driven bevel gears are respectively installed at one ends of the water feeding pipes 24 towards the circle center, for example, the driven bevel gears are fixedly sleeved outside the inlet end of each water inlet pipe 4, all the water inlet pipes 4 are connected with a main water feeding pipe (not shown in the figure) communicated with a water source through respective corresponding water conveying pipes (not shown in the figure) to feed water simultaneously, the driving bevel gear 25 is connected with an output shaft of a power component, so that when the water spraying device is used, the elevation angle of each water spraying head 1 can be adjusted to different height positions by adjusting the corresponding adjusting rod 11, a more three-dimensional spraying coverage range is presented, and under certain specific working conditions, the water spraying device has a more reasonable coverage range than a single cylindrical water curtain or a single curved surface or plane water mist.
