The invention discloses a spraying angle-adjustable spraying mechanism, belonging to landscaping spraying tools. The spraying angle-adjustable spraying mechanism structurally comprises a water inlet base, a connecting plate, a plurality of flexible spray pipes, slide blocks, adjusting assemblies, a cover plate and the like. The adjusting assemblies drive the slide blocks which are in threaded connection with the adjusting assemblies through the rotation of a driving screw rod to do a reciprocating motion so as to drive the top ends of the flexible spray pipes to do axial reciprocating swing, a multi-stage step structure or an oblique plane structure is creatively designed on each slide block, and a plurality of through holes are formed in the multi-stage step or the oblique plane, so that the top ends of the flexible spray pipes with the same height can penetrate through the slide blocks and stretch out; and due to the specificity of the step structure or the oblique plane structure, the heights of the top ends, stretching out of the through holes, of the flexible spray pipes are different, so that the oblique adjustment of the top ends of the flexible spray pipes in different angles can be realized through the axial reciprocating movement of the slide blocks. The improved structure is compact in design, small in volume, convenient to mount and reliable to operate.
