[0051] Working principle: in use, when the color, fixed pattern and rotating pattern combined pattern of the light emitted on the stage need to be adjusted, the first motor, the second motor and the third motor are started respectively, so that the color disc body 101, the fixed pattern disc body 201 and the rotating pattern disc body 301 can be driven to rotate through the corresponding driving pulley 6a and the transmission belt 7, until the required color, fixed pattern and rotating pattern are adjusted to the light emitting channel, when the light is emitted, the fourth motor is started to drive the pattern rotating pulley 305 to rotate, and the large gear ring 304 on the pattern rotating pulley 305 is engaged with each small gear ring 303, so as to drive the rotating pattern lens 302 to rotate, so as to complete the required light emission;

[0052] Wherein the positioning groove 802 on the fixed ring 801 corresponds to the position of the light emitting channel, and wherein two electromagnets 80656 in each fixed cylinder 8031 are connected in series, and the electromagnets 80656 in each fixed cylinder 8031 are controlled by the controller, in use, the electromagnets 80656 in the fixed cylinder 8031 at the corresponding position can be selected by the controller according to the required color, fixed pattern and rotating pattern to be energized;

[0053] At this time, the electromagnet 80656 generates an attractive force on the magnetic block 80655, pulling the second tooth plate 80653 to move downward, and since the second tooth plate 80653 is engaged with the rotating gear 8063, the rotating gear 8063 is driven to rotate, and the rotating gear 8063 is engaged with the first tooth plate 80646, so that the clamping rod 80644 moves away from the positioning rod 8035, so that the clamping rod 80644 is disengaged from the clamping groove 80310, and at this time, the clamping rod 80644 moves to the limit position, when the first tooth plate 80646 cannot continue to move, the second tooth plate 80653 continues to move downward, driving the rotating gear 8063 to continue to rotate, and the rotating support arm 80641 is driven to rotate upward around the end shaft 80642, so as to lift the positioning rod 8035 upward, until the top wall of the positioning rod 8035 contacts the upper plate body, at this time, the two ends of the conductive rod 8038 respectively contact the two side contacts 8039, and the upper plate body here refers to: the upper corresponding plate body of the rotating pattern positioning member 803c is the fixed pattern disc body 201, the upper corresponding plate body of the fixed pattern positioning member 803b is the color disc body 101, and the upper corresponding plate body of the color disc positioning member 803a is the fixed ring 801;

[0054] When the conductive rod 8038 is in contact with the two side contacts 8039 respectively, and the two side contacts 8039 are electrically connected with the outer conductive ring 804 and the inner conductive ring 805 respectively, and the outer conductive ring 804 and the inner conductive ring 805 at different positions are electrically connected with the first motor, the second motor and the third motor through the fixed contact 807 respectively, at this time the corresponding first motor, the second motor and the third motor are powered on to work, thereby driving the color disc body 101, the fixed pattern disc body 201 and the rotating pattern disc body 301 to rotate, when the color disc body 101 rotates to the position corresponding to the color lens 102 corresponding to the required color and the light emitting channel, the corresponding color disc positioning piece 803a moves to the position below the positioning groove 802, at this time the positioning rod 8035 is pushed by the clamping support module 8064 to continue to rotate upward, and is clamped into the positioning groove 802, thereby positioning and fixing the color disc body 101, and the same is true for the fixed pattern disc body 201 rotating, until the positioning rod 8035 on the fixed pattern positioning piece 803b is clamped into the color disc positioning piece 803a, and the end groove 8032 inside the bottom of the fixed cylinder 8031, thereby positioning and fixing the fixed pattern disc body 201, and the rotating pattern disc body 301 rotates, until the positioning rod 8035 on the rotating pattern positioning piece 803c is clamped into the fixed pattern positioning piece 803b, and the end groove 8032 inside the bottom of the fixed cylinder 8031.

[0055] When the positioning rod 8035 continues to move upward, the conductive rod 8038 is separated from the side contact 8039, so that the corresponding driving motor 5 is automatically powered off and stopped, wherein the first motor, the second motor and the third motor are non-self-locking system motors.

[0056] Meanwhile, the first motor, the second motor and the third motor are externally connected with independent control circuits, so that the multiple disc bodies with different functions are not simply stacked, but can be controlled by independent motors and control circuits, so that each disc body can be individually controlled in the motion state, such as rotation / stop, rotation speed and rotation direction, and through the control of different motion combinations of multiple disc bodies, the infinite dynamic effect superposition of “dynamic pattern + dynamic color + fixed / fine background” is realized, which is a function that cannot be realized by traditional single-layer or double-layer color disc.
