Illumination lamp with adjustable illumination angle

The utility model discloses an illumination lamp with an adjustable illumination angle. The illumination lamp comprises an installation block (21), a mounting frame (23); wherein the mounting frame (23) is rotatably connected with the mounting block (21), the lamp (1) is connected to the mounting frame (23), and the mounting frame (23) is provided with a plurality of spline grooves (242) which aredistributed in a radial shape; at least one lifting pin (22), wherein the lifting pin (22) is connected with the mounting block (21) in a sliding fit manner; and the third spring (25) drives the lifting pin (22) to abut against the spline groove (242). When the illumination angle of the lamp needs to be adjusted, only force needs to be applied to rotate the mounting frame, the transition surfaceof the spline groove can automatically push away the lifting pin, and when the illumination angle is adjusted to a proper angle, the mounting frame is released, the lifting pin can automatically abutagainst the spline groove,
