When the pressure head 11 is pressed tightly on the landing gear of the unmanned aerial vehicle 2, the toothed plate 10 is pushed to just press against the limit stop ear 16, so that the pressure head 11 remains stationary, and then the threaded sleeve 34 continues to move to drive the charging plug 6 to continue to move up, so as to be plugged into the charging port of the unmanned aerial vehicle 2 for charging.

[0024] The threaded rod 5 passes through the middle part of the pushing gear seat 28, and a pushing spring 31 is wound around the outer side of the threaded rod 5.

At this time, the reset spring 26 contracts and deforms, allowing the pushing gear seat 28 to move normally.

[0025] A guiding ridge 32 extends from the inner bottom surface of the arc-shaped groove 8, and a concave seat 33 extends from the lower end surface of the threaded sleeve 34. The concave seat 33 fits the outer surface of the guiding ridge 32. The cooperation between the guiding ridge 32 and the concave seat 33 guides the threaded sleeve 34. A No. 2 pulley 35 is coaxially inlaid at the end of the threaded rod 5, and a No. 1 pulley 22 is coaxially inlaid at the output end of the servo motor 3. A synchronous belt 23 is connected between the No. 1 pulley 22 and the No. 2 pulley 35.

[0026] When in use, the unmanned aerial vehicle 2 stops on the platform body 1, and then the servo motor 3 works to drive the threaded rod 5 to rotate, so that the threaded sleeve 34 tightened on the threaded rod 5 can move, so as to push the push gear seat 28 through the jacking spring 31. At this time, the reset spring 26 shrinks and deforms, allowing the push gear seat 28 to move normally, so that the push gear seat 28 drives the push gear frame 29 to move, and pushes the push gear plate 10, so that the push gear plate 10 can slide on the T-shaped slide seat 17, so as to drive the flip gear 15 to rotate, and then drive the pressure head 11 on the flip shaft 14 to flip, so as to press on the landing gear of the unmanned aerial vehicle 2, so as to firmly fix the unmanned aerial vehicle 2 on the platform body 1. In this process, the threaded sleeve 34 will also synchronously drive the charging push frame 4 to move to push the plug socket 7, so that the charging plug 6 moves up under the guidance of the guide edge rod 18 and the guide sleeve 20 to get close to the charging port of the unmanned aerial vehicle 2. When the pressure head 11 is pressed tightly against the landing gear of the unmanned aerial vehicle 2, the tooth plate 10 is pushed to just press against the limit stop ear 16, so that the pressure head 11 remains stationary, and then the threaded sleeve 34 continues to move to drive the charging plug 6 to continue to move up so as to be plugged into the charging port of the unmanned aerial vehicle 2 for charging. In this process, the pushing spring 31 contracts and deforms to offset the force generated by the continued movement of the threaded sleeve 34, so that the movement of the charging plug 6 will not be hindered while the pressure head 11 remains stationary.
