[0002] During construction, dust will be raised, and dust suppression is required. The sprinkler is inserted into the ground and fixed, and then the sprinkler sprays water mist to suppress the dust in the air.

[0003] For example, a Chinese patent with publication number CN215774643U discloses a mushroom sprinkler, comprising a sprinkler head and a mounting bracket; the sprinkler head can be rotatably connected to the mounting bracket; the sprinkler head is mushroom-shaped, and a central waterway and a plurality of branch waterways are arranged inside the sprinkler head, the central waterway is connected to an external water source, and the branch waterways are connected to the central waterway, the outer surface of the sprinkler head is arranged in an arc shape, and the outer surface of the sprinkler head is axially symmetrical or centrally symmetrically provided with a plurality of groups of water outlet grooves, and the water outlet grooves are connected to the branch waterways; the sprinkler head can rotate to spray by water pressure during spraying; the product is mushroom-shaped and has a beautiful appearance, and the arrangement and orientation of the nozzles and the orientation of the water outlet make the water sprayed outward form thrust, so that the sprinkler head rotates by the power of the water flow, and the oblique spraying makes the water flow during irrigation spray farther and the irrigation range larger; the rotatable structure of the sprinkler head makes the plant irrigation more sufficient and uniform, avoiding the occurrence of irrigation dead corners.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when used, such as: after the device is fixed to the ground, long-term placement may cause the entire device to tilt, and the tilt of the device will cause the watering angle to tilt, and then the device needs to be reinserted into the soil to fix it. At the same time, long-term use of the nozzle will cause the nozzle to be blocked, and then the entire device needs to be pulled out to repair the nozzle. After the repair is completed, the device needs to be inserted into the soil again, which wastes time. In view of this, we propose a construction sprinkler. Utility Model Content

When the sprinkler head needs to be taken out, the operating disk is rotated in the opposite direction to drive the worm to rotate, the worm gear engaged with it rotates, the worm gear drives the rotating column to rotate, and the rotating column drives several turntables to rotate. At this time, the circumferential arc surface of the turntable is no longer in contact with the sliding column. Under the action of the tension of the tension spring, the tension spring pulls the fixing ring to slide in the direction of the turntable, and the fixing ring drives the sliding column to slide in the direction of the turntable. When the sliding column enters the power chamber, it is convenient for personnel to pull out the fixed column.
