[0031] The locking mechanism 5 is fixedly arranged at the upper end of the rear support rod 18. The locking mechanism 5 comprises a bottom plate 23, an upper and lower adjustment pad 24, a moving plate 26, a moving seat 27, a fixed seat 28, and a tightening screw 31.
[0032] The bottom plate 23 is a horizontally arranged square plate-shaped structure, and two front and rear mounting grooves are arranged on the upper end surface of the bottom plate 23, and an up-and-down adjustment pad 24 is arranged inside each mounting groove. Four square array longitudinal grooves are arranged on the bottom plate 23, and the four longitudinal grooves extend along the front-to-back direction. A fixing bolt 25 passes downward inside each longitudinal groove, and a fixing nut is screwed on the lower end of the fixing bolt 25.
[0033] The movable plate 26 is a square plate-like structure arranged horizontally. The movable plate 26 is arranged at the upper ends of the two upper and lower adjustment pads 24. The lower end surface of the movable plate 26 contacts the upper ends of the two upper and lower adjustment pads 24. The height of the movable plate 26 can be adjusted by selecting the upper and lower adjustment pads 24 of different heights. A transverse groove is arranged at each of the four corners of the movable plate 26.

A tightening nut is threadedly connected to the end of the tightening screw 31 away from the handle. By tightening the tightening nut, the movable seat 27 and the fixed seat 28 can be fixed in the front and back directions.
[0036] When the drone is fixed on the locking mechanism 5, a fixing pin is inserted between the two fixing holes, and the fixing pin and the limit pin 30 pass through the fixing part of the drone, thereby fixing the drone to the two locking mechanisms 5; by tightening four fixing nuts and a tightening nut, the moving plate 26 and the moving plate 26 are fixed on the bottom plate 23, thereby ensuring that the drone is firmly fixed. When the drone needs to be launched, the fixing pin is replaced with a shear pin 29. When the turbojet engine is started, the engine thrust is not enough to shear the shear pin 29, and the drone is still parked on the front launcher 3 and the rear launcher 4. When the rocket booster is started, the thrust generated by the booster causes the shear pin 29 to break, and the drone takes off.
[0037] The base frame 6 includes a front base frame 32 , a rear base frame 33 , and a fixing frame 35 .
[0038] The front chassis 32 is fixedly arranged at the upper end surface of the front base 1, and the front chassis 32 is located between the left and right front inverted fixing seats 14.

A transport frame fixing seat 34 is fixedly arranged on the upper end surface of the rear base 2. The rear chassis 33 is clamped inside the transport fixing seat 28. Bolts pass through the transport frame fixing seat 34 and the rear chassis 33 and are fixed by nuts, thereby fixing the rear chassis 33 to the rear base 2.
[0040] The fixing frame 35 is a frame structure extending along the front-to-back direction. The front lower side of the fixing frame 35 is fixedly connected to the upper end of the front base frame 32 , and the rear lower side of the fixing frame 35 is fixedly connected to the upper end of the rear base frame 33 .
[0041] The lower support 7 is fixedly provided at the front and rear ends of the upper end face of the fixed frame 35, and the lower support 7 is a "︺"-shaped rod-like structure located in the left and right vertical planes, and a "︺"-shaped lower support groove is provided inside the lower support 7. The fixed pressure plate 8 is a "︷"-shaped rod-like structure located in the left and right vertical planes, and a "︷"-shaped upper support groove is provided inside the fixed pressure plate 8.

A lifting ring 36 is fixedly provided on the upper side of the two ends of the fixed pressure plate 8, and the transport frame and the drone can be lifted as a whole through the four lifting rings 36 on the two fixed pressure plates 8.
[0042] The working principle of the present invention is: When the drone needs to be transported, the front support rod 10 and the rear support rod 18 are both in a horizontal state, and the two front support rods 10 are fixed inside the two front inverted fixing seats 14 by the second fixing pins 16, and the two rear support rods 18 are fixed inside the two rear inverted fixing seats 20 by the fourth fixing pins 22. Then, the front support frame and the rear support frame are both inverted, which will not interfere with the transportation of the drone, and can also lower the center of gravity of the combined bracket during transportation, thereby improving the stability during transportation.
[0043] During transportation, the front and rear reinforcement rings of the UAV are respectively clamped into the lower support grooves of the two front and rear lower supports 7 of the transport frame, and then the two fixed pressure plates 8 are fixed to the two lower supports 7, thereby fixing the UAV on the transport frame.
[0044] Before transporting to the designated location for launch, the transport frame is separated from the front base 1 and the rear base 2, and then the transport frame and the UAV are hoisted as a whole using four lifting rings 36, so that the transport frame is separated from the front base 1 and the rear base 2. Then the second fixing pin 16 and the fourth fixing pin 22 are removed, the front support rod 10 and the rear support rod 18 are rotated upward to a vertical state, and the rear support rod 18 is fixed to the rear rotating frame 17 by the third fixing pin 21. Then the UAV is parked on the front support seat 11 and the locking mechanism 5, so that the front side of the UAV is engaged with the front support seat 11 at the upper end of the front support rod 10, so that the front support rod 10 is also in a vertical state under the action of the UAV.
[0045] When the drone is fixed on the locking mechanism 5, a fixing pin is inserted between the two fixing holes, and the fixing pin and the limit pin 30 pass through the fixing part of the drone, thereby fixing the drone to the two locking mechanisms 5; by tightening four fixing nuts and a tightening nut, the moving plate 26 and the moving plate 26 are fixed on the bottom plate 23, thereby ensuring that the drone is firmly fixed. When the drone needs to be launched, the fixing pin is replaced with a shear pin 29. When the turbojet engine is started, the engine thrust is not enough to shear the shear pin 29, and the drone is still parked on the front launcher 3 and the rear launcher 4. When the rocket booster is started, the thrust generated by the booster causes the shear pin 29 to break, and the drone is separated from the locking mechanism 5 and completes takeoff. When the drone takes off, the front support seat 11 is out of contact with the drone, so that the front support rod 10 is rotated downward to a horizontal state under the action of the first torsion spring, so that the booster of the drone will not collide with the front support rod 10.
