Similarly, a mounting plate 17 can be horizontally arranged to support the motor 6.

[0033] Working principle:

[0034] By energizing the electromagnet 9, the electromagnet 9 has magnetic force, and then the arc iron plate 11 is adsorbed by the magnetic force, so that the rotating shaft 2 in the through hole is clamped by the arc iron plate 11, and the connecting key 14 on the arc iron plate 11 is aligned with the key slot of the rotating shaft 2 and inserted, and then the rotating seat 5 is driven by the motor 6 to rotate, so as to achieve the purpose of driving the rotating shaft 2 to rotate, so that the rotating shaft 2 drives the wire rope 25 to move, and the red flag is raised or lowered; when it is necessary to manually raise the flag, the electromagnet 9 is powered off, and its magnetic force disappears. Under the action of the tension spring 12, the arc iron plate 11 is away from the rotating shaft 2, and the clamping effect disappears. At this time, the flag-raising ceremony can be manually completed by the crank 3, and the structure is simple and easy to use.
