secondly, when the rotating ring 304g rotates outwards, the repulsive force between the magnet ring 304h on the rotating ring and the cylindrical magnet piece 304f close to the side thereof is rapidly increased, so that the elastic force of the jacking spring 303d close to one side of the cylindrical magnet piece 304f after being compressed is overcome, and the jacking spring 303d on the other side is released, because the sleeving connection cannot fall down, the square column 304c without the cylindrical magnet piece 304f is only used for limiting installation, and does not protrude outside the square cavity channel 304a, so that stable plugging can be ensured in the square cavity channel 304 a;

thirdly, after the cylindrical magnet piece 304f is pushed outwards by the magnet ring 304h, the square column 304c on the side slides to one side together with the fixing frame 304b and the direct current dry battery 303b, so that the motor of the direct current dry battery 303b is just abutted to the conducting strip 303c, the circuit of the solenoid 302c is communicated, the permanent magnet piece 202 and the sunshade net 13 are repelled to jack up and open for effective photosynthesis, and when the magnet ring 304h rotates inwards and retracts, the direct current dry battery 303b is retracted together with the square column 304c, the conducting strip 303c is restored to open circuit, and the sunshade net 13 restores horizontal sunshade effect;

fourthly, the pair of conducting strips 303c on the side of the cylindrical magnet piece 304f is not provided, and after the side of the cylindrical magnet piece 304f is pushed in by hand, contact conduction can be carried out, at the moment, the hand is not taken away, the sunshade net 13 keeps rotating and opening, operations such as pesticide spraying and fruit picking can be carried out in a short time, once the hand is taken away, the sunshade net 13 recovers the horizontal sunshade effect, therefore, the group of conducting strips 303c on the side are used for conducting contact when being driven by hand, and the sunshade net 13 is effectively rotated and opened in a short time;

fifthly, the conducting plate 303c comprises a bowl-shaped conducting plate body arranged on the inner top surface of the battery jar 303a and a strip-shaped conducting plate body arranged on the bowl-shaped conducting plate body and penetrating through the U-shaped frame plate 301 to be arranged upwards, the supporting spring 303d is arranged in the bowl-shaped conducting plate body, so that the conducting plate 303c has the bending strength of the bowl-shaped conducting plate body and the driving force for keeping the two parts of the elastic force of the supporting spring 303d to be bent, when the electrode of the direct current dry battery 303b is contacted, the electrode is ensured to be stably abutted against the electrode, and after the direct current dry battery 303b is removed, the direct current dry battery 303b can be bent and jacked up again to be contacted next time, and the electrode of the direct current dry battery 303b is ensured to have;

sixthly, just because there are two sets of the conductive sheets 303c, one of the conductive plates 302d on the two solenoids 302c on both sides has two wires welded for conduction, and the other conductive plate 302d is connected in series with the next solenoid 302c through one wire, so that it is ensured that the two sets of the conductive sheets 303c can effectively communicate with all the solenoids 302 c.
