[0028] In the initial state, the two locking blocks 5 are respectively squeezed by the two limiting plates 14, so that the opposite faces of the two locking blocks 5 are attached to each other. At this time, the two locking springs 4 are both in a stretched state. When installing and fixing the tail fin 6, pull the pull plate 13 outwards to drive the two limiting plates 14 to move outwards along the two limiting grooves 9 respectively. During this process, the two positioning springs 12 are in a stretched state. Finally, the two limiting plates 14 are separated from the two locking blocks 5 respectively, and the two locking springs 4 rebound, respectively causing the two locking blocks 5 to retract into the retractable slots 3. Then, insert the insertion plate 7 connected to the top of the tail fin 6 into the slot 2. Release the pull plate 13, and the two positioning springs 12 rebound, causing the pull plate 13 to return to the pull plate groove 10. And by the same principle, the two limiting plates 14 respectively squeeze the two locking blocks 5 to approach each other, and the two locking blocks 5 enter the locking grooves 8 opened in the insertion plate 7, so that the insertion plate 7 is fixed in the slot 2, and thus the tail fin 6 is fixed.

[0031] Working principle: In the initial state, the two locking blocks 5 are respectively squeezed by the two limit plates 14, so that the opposite faces of the two locking blocks 5 are in contact with each other. At this time, the two locking springs 4 are both in a stretched state. When installing and fixing the tail fin 6, pull the pull plate 13 outwards to drive the two limit plates 14 to move outwards along the two limit grooves 9 respectively. During this process, the two positioning springs 12 are in a stretched state. Finally, the two limit plates 14 are separated from the two locking blocks 5 respectively, and the two locking springs 4 rebound, respectively retracting the two locking blocks 5 into the retractable grooves 3. Then, insert the insertion plate 7 connected to the top of the tail fin 6 into the insertion slot 2. Release the pull plate 13, and the two positioning springs 12 rebound, causing the pull plate 13 to return to the pull plate groove 10. And by the same principle, the two limit plates 14 respectively squeeze the two locking blocks 5 to approach each other, and the two locking blocks 5 enter the locking grooves 8 opened in the insertion plate 7, fixing the insertion plate 7 in the insertion slot 2, and thus fixing the tail fin 6. When removing the tail fin 6, pull the pull plate 13 by the same principle to make the two locking blocks 5 disengage from the insertion plate 7, and then the tail fin 6 can be removed.
