Then starting the cylinder 16 to drive the support plate 18 to move upwards, the support plate 18 moves upwards to drive the password transportation box 19 to move upwards to the transportation cavity 25, the password transportation box 19 moves towards the transportation cavity 25 to make, the movable conical block 23 moves towards one side close to the center line of the password transportation box 19 under the drive of the end wall of the transportation cavity 25 and compresses the fixed spring 22, when the movable conical block 23 moves to the inner side of the connection cavity 32, the resilience force of the fixed spring 22 is far greater than the compression force of the connection spring 31, so that the movable conical block 23 moves towards the connection cavity 32 under the drive of the fixed spring 22 and drives the sliding closing block 30 to move towards one side far away from the center line of the transportation cavity 25.

3. The sliding closing block 30 moves to the side far from the center line of the transportation chamber 25 to compress the connecting spring 31 and drive the sliding plate 70 to move downwards through the connecting rod 61, the sliding plate 70 moves downwards through the engaging rod 65 to drive the pressure block 66 to move to the side close to the center line of the transportation chamber 25, the pressure block 66 first compresses the engaging spring 67, when the clamping groove 20 moves to the inner side of the pressure chamber 69, the connecting clamping block 68 moves to the side close to the center line of the school transportation chamber 25 to move into the clamping groove 20 under the drive of the engaging spring 67, so that the connecting clamping block 68 is clamped in the clamping groove 20, and the movable conical block 23 is clamped in the connecting chamber 32.

4. Then the pushing head 54 is manually pushed to move to the right, the pushing head 54 moves to the right to drive the left pushing block 55 to move to the right, the left pushing block 55 moves to the right to drive the threaded shaft 59 to rotate by the threaded block 56 to move to the side close to the center line of the transportation cavity 25, the threaded shaft 59 rotates to drive the engaging pulley 60 to rotate, the engaging pulley 60 rotates to drive the driving pulley 28 to rotate by the driving belt 27, the driving pulley 28 rotates to drive the connecting shaft 29, and the connecting shaft 29 rotates to drive the right pushing block 55 to move to the side close to the center line of the transportation cavity 25.

5. The pushing block 55 moves to a side close to the center line of the transportation cavity 25 to drive the connecting plate 71 and the triangular block 74 to move to a side close to the center line of the transportation cavity 25, the connecting plate 71 moves to a side close to the center line of the transportation cavity 25 to compress the compression spring 72, the triangular block 74 moves to a side close to the center line of the transportation cavity 25 to drive the charging latch 53 to move downwards, the charging latch 53 moves downwards to electrically disconnect the connecting charging block 50 from the connecting charging block 51, and when the charging latch 53 leaves the supporting cavity 52, the flying shell 26 flies to a destination needing to send a workpiece.

6. After the flight shell 26 flies to the destination where the delivery is needed, the recipient takes out the express mail by inputting the correct password on the password input block 33.

The above description is only an embodiment of the invention, but the scope of the invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the invention. Therefore, the protection scope of the invention should be subject to the protection scope defined by the claims.
