In this process, the protection mechanism 33 and the auxiliary mechanism 45 are used for synchronously limiting the rotation angle of the stage lamp 44 and adjusting the brightness of the lamp light through the resistor, so that the stage lamp 44 can be adjusted through two ways, and the situation that the lamp light of the stage lamp 44 causes dazzling of audiences is avoided.
The invention integrally works as follows:
preparing work: the adjusting rotary drum 322 is rotated according to actual use requirements, under the action of the limiting telescopic rod 338, the adjusting rotary drum 322 is rotated to drive the adjusting screw 323 to move left and right to a proper position, so that the protection mechanism 33 is driven to move to a proper position, and at the moment, the rotation angle of the stage lamp 44 is adjusted, and the sensitivity of the protection mechanism 33 for limiting the stage lamp 44 is also adjusted;
