A spraying angle adjustable spraying mechanism, comprising a water inlet base (1), a connecting plate (5), a plurality of flexible spray pipes (3), slide blocks (6), adjusting assemblies (2), a cover plate (4) and the like. The adjusting assemblies (2) drive, by means of the rotation of a driving screw rod (21), the slide blocks (6) which are in threaded connection with the adjusting assemblies (2) to do a axial reciprocating movement so as to drive top ends of the plurality of flexible spray pipes (3) to do axial reciprocating swing; each slide block (6) has a multi-stage step structure or oblique plane structure, and a plurality of through holes (61) are provided in the multi-stage steps or the oblique plane, so that the top ends of the plurality of flexible spray pipes (3) installed at same height can penetrate through the slide blocks (6) 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 (61), of the flexible spray pipes are different, so that oblique adjustment on the top ends of the flexible spray pipes (3) in different angles can be realized by means of the axial reciprocating movement of the slide blocks (6). The spraying mechanism is compact in structure and small in size; moreover, installation is convenient and operation is reliable.
