An opening and closing door 14 is arranged through the bottom of the storage box 1. The opening and closing door 14 is rotatably connected with the storage box 1. The inner wall of the storage box 1 is fixedly connected with a second clamping plate 15 at the end far from the first clamping plate 7. Since the technical means of making the first clamping plate move closer to the second clamping plate while closing the opening and closing door is adopted, the items can be put into the storage box after closing the opening and closing door. In the process of the first clamping plate moving closer to the second clamping plate, it will first contact the items. When the items contact both the first clamping plate and the second clamping plate at the same time, the items can be clamped and fixed, avoiding shaking during flight and affecting the flight attitude, effectively solving the problem that the existing drone throwing mechanism in the background technology is very troublesome to operate, requires a lot of time for adjustment, increases the working time to a certain extent, and affects the efficiency of the throwing work, and then realizing the technical effects of simple and convenient operation, facilitating the fixing and throwing of items, facilitating the progress of the throwing work, and being able to improve the working efficiency.

[0024] In this embodiment, a plurality of installation grooves are arranged at equal intervals at the top of the opening and closing door 14. A roller 16 is arranged in the installation groove of the opening and closing door 14. The roller 16 is rotatably connected with the opening and closing door 14.

[0025] In this embodiment, two limiting rods 17 are arranged on both of the two L-shaped plates 10. The L-shaped plates 10 are slidably connected with the limiting rods 17. Two square plates 18 are fixedly connected to both sides of the storage box 1. The limiting rods 17 are fixedly connected with the square plates 18.

[0026] In this embodiment, two fixing plates 19 are fixedly connected to both top ends of the storage box 1. The four fixing plates 19 are all fixedly connected with the same drone body 20.

[0027] In this embodiment, a housing 24 is fixedly connected to the bottom of the drone body 20. The housing 24 is fixedly connected to the top of the storage box 1.

[0028] In this embodiment, a motor 23 is arranged inside the outer shell 24. The motor 23 is electrically connected to the power supply of the UAV body 20. The motor 23 is fixedly connected to the storage box 1. The output end of the motor 23 is fixedly connected with a second gear 22. The second gear 22 is meshed with a first gear 21. The first gear 21 is sleeved on the outer wall of the bidirectional lead screw 3. The first gear 21 is fixedly connected to the bidirectional lead screw 3.

[0029] In this embodiment, a chute 25 adapted to the slider 6 is formed at the top of the storage box 1. The slider 6 is arranged in the chute 25. The slider 6 is slidably connected to the storage box 1.

[0030] Working principle: When using this device, the item to be thrown can be placed on the roller 16. Start the motor 23 using the remote control. The output end of the motor 23 will drive the second gear 22 to rotate. The second gear 22 will drive the first gear 21 to rotate. The first gear 21 will drive the bidirectional lead screw 3 to rotate. The bidirectional lead screw 3 will drive the first lead screw nut 4 and the second lead screw nut 8 to approach each other. The second lead screw nut 8 will move towards the direction of the first gear 21. The second lead screw nut 8 will drive the second sleeve plate 9 to move. The second sleeve plate 9 will drive the L-shaped plate 10 to move along the limiting rod 17. The movement of the L-shaped plate 10 will also drive the collar 11 to move. The collar 11 will drive the round rod 12 to move. The round rod 12 will drive the ring 13 to move. When the ring 13 continues to move when it touches the opening and closing door 14, the ring 13 will squeeze the opening and closing door 14 to make the opening and closing door 14 swing with the position where the opening and closing door 14 passes through the storage box 1 as the center, so that the opening and closing door 14 gradually closes, making the storage box 1 in a closed environment, and the item to be thrown can be put into the storage box 1. Subsequently, when the output end of the motor 23 continues to rotate, the first lead screw nut 4 continues to move. The movement of the first lead screw nut 4 will drive the first sleeve plate 5 to move. The first sleeve plate 5 will drive the slider 6 to move along the chute 25. The movement of the slider 6 will drive the first clamping plate 7 to move closer to the item until it contacts the item. At this time, if the bidirectional lead screw 3 continues to rotate, the ring 13 will move along the bottom of the opening and closing door 14. The first clamping plate 7 will drive the item to move closer to the second clamping plate 15 until the item contacts the second clamping plate 15. The item can be clamped by the first clamping plate 7 and the second clamping plate 15, avoiding the item shaking during flight and affecting the flight attitude. When reaching the throwing location, reverse the output end of the motor 23 to make the first lead screw nut 4 and the second lead screw nut 8 move away from each other, and the ring 13 can move back to the initial position gradually, no longer being directly below the opening and closing door 14. Under the action of gravity, the opening and closing door 14 will gradually open. At the same time, the first clamping plate 7 will also move away from the second clamping plate 15, no longer clamping the item, and the item will move out of the storage box 1 along the roller 16, and the item can be thrown out.
