the top end of the inner wall of the connecting rod (609) is provided with a circular through hole, the diameter of the circular through hole is twice that of the ejector rod (608), the number of the connecting rod (609) and the accessory components thereof is two, and the connecting rod (609) and the accessory components thereof are symmetrically arranged about the horizontal center line of the spray head (400);
the left side of the spring (602) is fixedly connected with the movable frame (501), and the movable rod (601) is fixedly connected with the left side of the movable frame (501);
a limiting block is fixedly arranged at the top end of the movable rod (601) on the right side of the rotating head (604), and the spring (602) is a compression spring;
when the medicine box is used, the medicine box (200) conveys medicine liquid to the spray head (400) through the medicine spraying pipe (300), the pushing force generated when the medicine liquid enters the spray head (400) is acted on the movable frame (501) so as to push the movable frame (501) to move rightwards, the half spiral groove (503) extrudes the rolling ball (510) when the movable frame (501) moves so that the elliptical plate (509) rotates, the elliptical plate (509) drives the bent rod (507) to rotate, the bent rod (507) drives the first spring pull rod (508) to move, the first spring pull rod (508) drives the convex rod (505) to move while rotating relative to the convex rod (505), the convex rod (505) drives the movable plate (504) to move, when the convex rod (505) moves to be close to the fixed block (506), the fixed block (506) and the convex rod (505) attract each other, the convex rod (505) drives the moving plate (504) to move continuously, so that an overflowing through hole which is originally blocked by the moving plate (504) and is arranged on the movable frame (501) is exposed, then the liquid medicine enters the inner wall of the right side of the spray head (400) through the overflowing through hole, when the movable frame (501) moves rightwards, the movable frame (501) drives the movable rod (601) to move by overcoming the acting force of the spring (602), the torsion spring (603) and the rotating head (604) are driven by the movable rod (601) to move, the rotating head (604) is contacted with the stopper (605), then the stopper (605) is driven by the rotating head (604) to move, the transmission slider (606) drives the connecting rod (609) to move by overcoming the acting force of the second spring pull rod (607), the connecting rod (609) carries the contact pin (610) to move, the contact pin (610) enters the spray hole (700) to dredge the contact pin, liquid medicine sediment and particles remained in the spray hole (700) are extruded out, the spray hole (700) is dredged to prevent the spray hole (700) from being blocked, then the transmission slide block (606) continues to move to the rightmost side, the ejector rod (608) pushes the rotating head (604) to rotate against the acting force of the torsion spring (603), so that the rotating head (604) does not exert the acting force on the stop head (605), the transmission slide block (606) moves leftwards under the action of the second spring pull rod (607) to return to the original point, the connecting rod (609) and the contact pin (610) are driven to return to the original point, then the liquid medicine is sprayed out from the inner wall of the spray head (400) through the spray hole (700), when the unmanned aerial vehicle (100) stops running, the liquid medicine does not exert pushing force on the movable frame (501), and then the movable frame (501) returns to the original point under the action of the spring (602).
