Irrigation sprinkler and pipeline fixing device

The invention provides a fixing device which is used for fixing pipelines different in diameter and sprinklers in a sprinkling irrigation system. The irrigation sprinkler and pipeline fixing device comprises a support stabilizing plate, double-end studs, ground inserting needles and a spare nut. The double-end studs can prevent a pipeline from moving vertically. The support stabilizing plate is composed of a bottom plate with guide rails, movable fixing plates, positioning bolts and support pipe positioning ribs. The tops of the movable fixing plates are provided with ground inserting needle holding holes and reinforcing plates on two sides. The bottom plate and the movable fixing plates are connected with T-shaped guide rails through bottoms of the reinforcing plates, and the ground inserting needles are connected with the bottom plate in a threaded manner. When using the irrigation sprinkler and pipeline fixing device in a field, a user only needs to fix connected pipelines between the fixing plates, connect a sprinkler with a vertical pipe and insert the ground inserting needles into the soil. When to move and demount the fixing device, the user can loosen sprinkling irrigation pipelines at two ends of a tee joint and pull out the sprinkler and pipeline fixing device together with the sprinkler and the vertical pipe. The irrigation sprinkler and pipeline fixing device is reliable in connection, convenient to move, timesaving and laborsaving and applicable to flat cement ground, fields and slopes.
