when two magnets in the magnetic tension controller are heteropoles, larger damping can be generated due to the fact that the two magnets are opposite in polarity, the paying-off speed is reduced, when the two magnets are the same in polarity, the two magnets repel each other correspondingly, the damping is minimum, the paying-off speed is in an accelerating state, the paying-off speed is transmitted to a right end plate rotating shaft through a synchronous pulley set, and rotating resistance which can be adjusted along with cable tension is applied to the rotation of the optical cable disc 11;
the first embodiment is as follows:
(1) When the damping value of the magnetic tension controller 12 is between the first positive damping value and the first negative damping value, the left and right oscillating bars 16 are pulled to oscillate up and down through the cable tension, and the damping of the rotating shaft of the magnetic tension controller 12 is adjusted to be maintained between the first positive damping value and the first negative damping value through the magnetic tension controller 12 connected with the oscillating bars 16, so that the optical cable disc is ensured to rotate at a constant speed;

Example two: the difference is that a buffer spring matched with the slide block is arranged in the buffer chute,
in addition to the effect of the first embodiment, the swing rod 16 further swings to drive the sliding block to slide in the buffering sliding groove 21, and the relative movement enables the damping of the rotating shaft of the magnetic tension controller 12 to be under the action of the magnet and to be matched with the restoring force of the buffering spring, so that the damping of the tension controller 12 and the restoring force of the combined buffering spring are overcome, and the unmanned aerial vehicle is more favorably adjusted between the first positive damping value and the first negative damping value, and the flying attitude of the unmanned aerial vehicle is stabilized.

when the damping value of the magnetic tension controller (12) reaches the second positive damping value or the second negative damping value; the swing rod (16) drives the sliding block (22) to slide in the buffering sliding groove (21), the damping of the tension controller (12) is overcome, the collision needle touches the throwing touch switch (23), and the unmanned aerial vehicle pay-off rack is thrown down.
9. An application method of the unmanned aerial vehicle pay-off rack adopts the unmanned aerial vehicle pay-off rack of claim 7, and is characterized in that: the using method of the pay-off rack of the unmanned aerial vehicle is provided with a first positive damping value, a second positive damping value, a first negative damping value and a second negative damping value according to the damping value of the magnetic tension controller (12);
when the damping value of the magnetic tension controller (12) is between the first positive damping value and the first negative damping value, the left and right swing rods (16) are pulled to swing up and down through the tension of the cable, and the damping of the rotating shaft of the magnetic tension controller (12) is adjusted to be maintained between the first positive damping value and the first negative damping value through the magnetic tension controller (12) connected with the swing rods (16), so that the optical cable disc (11) is ensured to rotate at a constant speed;
when the damping value of the magnetic tension controller (12) is between the first positive damping value and the second positive damping value or between the first negative damping value and the second negative damping value, the left swing rod (16) and the right swing rod (16) are pulled to swing up and down through cable tension and combined with a buffer spring matched with the sliding block (22), the relative state of a magnet of the magnetic tension controller (12) is further changed through the swing rods (16), the damping of the tension controller (12) and the restoring force of the buffer spring are overcome, the damping of a rotating shaft of the magnetic tension controller (12) is adjusted to be maintained between the first positive damping value and the first negative damping value, the optical cable disc (11) is ensured to rotate at a constant speed, the swing rods (16) drive the sliding block (22) to slide, and as the second positive damping value or the second negative damping value is not reached, a touch needle cannot touch a throwing switch (23), and the throwing of the unmanned aerial vehicle pay-off stand caused by misoperation is avoided from dropping;
when the damping value of the magnetic tension controller (12) is at the second positive damping value or the second negative damping value; the swing rod (16) drives the sliding block (22) to slide, the damping of the tension controller (12) is overcome, the restoring force of the buffer spring is combined, the touch needle touches the throwing touch switch (23), and the unmanned aerial vehicle pay-off rack is thrown.
