[0034] Furthermore, the clutch mode of the motor 2 and the cam 4 is electromagnetic coil clutch.

[0035] The present invention provides a driving clutch for a distributed fill light adjustment system through improvement, and its working principle is as follows:

[0036] First, the outer frame 1 is the outer shell of the clutch, and is the carrier and fixing structure of the entire clutch. A motor 2 is arranged inside the outer frame 1 and is installed and fixed by a motor bracket 3;

[0037] Second, the output shaft of the motor 2 passes through the motor bracket 3, and the end is connected to the cam 4, so that the motor 2 drives the cam 4 to rotate after working;

[0038] Third, an opening is provided on the right side of the outer frame 1, a positioning hole 61 is provided on the spline sleeve 6 to be matched and fixed with the opening on the right side of the outer frame 1, and a retaining ring 63 is provided on the spline sleeve 6 near the inner side of the positioning hole to limit the position of the spline sleeve 6 after installation;

[0040] Fifth, the cam 4 is driven by the motor 2 to rotate. After the cam 4 rotates to the point where the protruding end contacts the gear 8, it pushes it and causes the spline shaft 5 to move on the axis in the spline sleeve 6 to compress the spring 7, causing the gear 8 to disengage from the rack 9 and lose transmission. When the cam 4 rotates to the other end, the spring 7 is reset, causing the gear 8 to re-engage with the rack 9 for transmission, thereby enabling the gear 8 to move linearly and rotationally along the axis through the spline shaft 5 in the spline sleeve 6.

[0041] The present invention provides a driving clutch for a distributed fill light adjustment system through improvement. The spline shaft 5 and the spline sleeve 6 are modified so that the gear 8 can move linearly and rotationally along the axis in the spline sleeve 6 through the spline shaft 5; the motor 2 drives the cam 4 to rotate, and cooperates with the spring 7 to drive the spline to move on the axis, thereby realizing the clutch of the gear 8 and the transmission rack 9, and the cam 4 and the spring 7 cooperate in a slow clutch mode. The clutch adopts a small box-shaped structure, which is convenient for independent use and is suitable for use in harsh environments such as humidity and dust, thereby extending the service life in the humid environment of the greenhouse.
