While moving, the slider 804 can drive the disc 803 to move synchronously, so that the disc 803 is no longer engaged with the groove on the surface of the first toothed belt pulley 805, so that when the rotating shaft 10 rotates, it will not drive the first toothed belt pulley 805 to rotate. According to the above operation, the group of discs 803 and the first toothed belt pulley 805 to be reeled in are kept connected, and the other groups are disconnected. After the adjustment is completed, the motor 6 on one side of the first reel 18 is controlled to work, so that the motor 6 can drive the group of first reels 18 to be reeled in to rotate (the specific process is the same as above), so that the first reel 18 can reel in the covering net 12.
