The front end of the U-shaped arm 6 is detachably installed with a support frame 8, and a camera clamp 9 is inserted at the front end of the support frame 8. The camera clamp 9 is used to clamp and fix the camera. By driving the rotating shaft 5 and the U-shaped arm 6 to rotate through the rotating driving member 7, the support frame 8 and the camera clamp 9 are driven to deflect, thereby driving the camera to deflect in the vertical plane and adjusting the shooting angle. In addition, through the detachable installation between the U-shaped arm 6 and the support frame 8 and between the support frame 8 and the camera clamp 9, it is convenient to remove the camera clamp 9. After installing the camera inside the camera clamp 9, the camera clamp 9 is installed at the front end of the support frame 8 again. The effect of facilitating the installation and disassembly of the camera is achieved. After shooting, it is convenient to remove the camera and connect it to a computer to transmit and save the captured pictures and videos to the computer.

[0022] During use, the connecting component 3 includes an inner arc plate 301 and an outer arc plate 302. The inner arc plate 301 is fixedly installed on the side surface of the suspension 2. The inner arc plate 301 is inclined and fits on the surface of the inclined leg 101. Moreover, the inclination angle of the inner arc plate 301 is the same as the inclination angle of the inclined leg 101. The outer arc plate 302 fits on the surface of the inner arc plate 301, and the inner arc plate 301 and the outer arc plate 302 clamp both sides of the inclined leg 101. Two first threaded rods 303 are fixedly installed on the side of the inner arc plate 301 facing the outer arc plate 302.

Thus, when installing the suspension 2, by supporting the bottom of the suspension 2 with the hand and moving the suspension 2 upward until the inner arc plate 301 closely adheres to the surface of the inclined leg 101. Then, the outer arc plate 302 is fitted on the surface of the inner arc plate 301, the first threaded rods 303 pass through the first through holes 304, and finally the first nut 305 is screwed onto the first through holes 304, and the inner arc plate 301 and the outer arc plate 302 can be clamped on the inclined leg 101. The installation of the suspension 2 is completed.

[0023] Specifically, the lower half of the front end of the fixed seat 4 is provided with an arc surface. The surface of the fixed seat 4 is penetrated with a mounting hole 401 and an arc groove 402. The arc center of the arc groove 402 and the arc surface coincides with the center of the mounting hole 401. The end of the rotating shaft 5 is rotatably connected in the mounting hole 401. Slide columns 601 and arc plates 602 are fixedly installed on both the left and right sides of the U-shaped arm 6. The slide columns 601 are slidably connected in the arc groove 402, and the arc plates 602 are attached to the arc surface. The rotation driving member 7 includes a first gear 701 fixedly installed in the middle of the rotating shaft 5. A second gear 702 is engaged behind the first gear 701. A motor 703 is fixedly installed at the center of the second gear 702. The model of the motor 703 is: TMO2606-90.

[0024] Arc portions 201 are provided at both ends of the suspension 2. The arc portions 201 are attached to the bottom of the drone 1. A battery 704 is fixedly installed at the top of the suspension 2. The battery 704 is electrically connected to the motor 703. Through the setting of the arc portions 201, a space for installing the battery 704 is formed between the suspension 2 and the drone 1. By driving the second gear 702 to rotate through the motor 703, the first gear 701 is driven to rotate, thereby driving the rotating shaft 5 to rotate, so that the U-shaped arm 6 deflects. And during this process, the slide columns 601 slide inside the arc groove 402, and the arc plates 602 slide while being attached to the arc surface of the fixed seat 4. This makes the deflection of the U-shaped arm 6 more stable.

[0025] In addition, the central angle of the arc groove 402 is equal to or greater than ninety degrees. This enables the U-shaped arm 6 to deflect to a horizontal state and a vertical state. When the drone 1 takes off and lands, the U-shaped arm 6 can deflect to a horizontal state, so that the camera is in a horizontal state, increasing the distance between the camera and the ground and preventing the camera from colliding with the ground.

[0026] A first connecting plate 603 and a second connecting plate 604 are fixedly installed between the two fixed seats 4. An arc rod 605 is fixedly installed between the first connecting plate 603 and the second connecting plate 604. The arc center of the arc rod 605 coincides with the center of the mounting hole 401. A slide plate 606 is fixedly installed inside the U-shaped arm 6. The arc rod 605 passes through the slide plate 606, and the slide plate 606 is slidably connected to the arc rod 605. A spring 607 is sleeved outside the arc rod 605. Both ends of the spring 607 are respectively fixedly installed at the bottom of the slide plate 606 and the front side of the second connecting plate 604. After the U-shaped arm 6 deflects downward, the spring 607 is compressed and contracted. Through the elasticity of the spring 607, the U-shaped arm 6, the support frame 8, the camera fixture 9 and the camera are supported.

[0027] In reality, the support frame 8 includes an arch frame 801. Two through holes II 802 are formed through the rear side of the arch frame 801. Two threaded rods II 608 are fixedly installed at the front end of the U-shaped arm 6. The threaded rods II 608 are inserted into the through holes II 802. A threaded collar 803 is threadedly connected to the surface of the threaded rods II 608. On both opposite sides of the two ends of the arch frame 801, U-shaped plates 804 are fixedly installed. Through grooves 805 are formed at both ends of the arch frame 801. The through grooves 805 communicate with the U-shaped plates 804. Through holes III 806 are formed through the tops of the U-shaped plates 804. Thus, by screwing the threaded collar 803 off the threaded rod II 608, the arch frame 801 can be removed from the threaded rod II 608. Conversely, after installing the arch frame 801 on the threaded rod II 608, screwing the threaded collar 803 onto the threaded rod II 608 can complete the disassembly and installation of the arch frame 801, which facilitates the installation and disassembly.

[0028] The camera fixture 9 includes two clamps 901. The two clamps 901 are arranged vertically and fit together. Bolts 902 are arranged through the ends of the two clamps 901. The bolts 902 pass through the through holes III 806. Nuts II 903 are threadedly connected to the surfaces of the bolts 902. The nuts II 903 are in contact with the tops of the U-shaped plates 804. When installing the camera fixture 9 and the camera, the camera fixture 9 can be first disassembled from the support frame 8. Then, the two clamps 901 are clamped on the upper and lower sides of the camera. After that, the two clamps 901 and the camera are inserted into the front end of the arch frame 801, that is, the ends of the clamps 901 are inserted into the U-shaped plates 804. Then, the bolts 902 are inserted into the ends of the two clamps 901 and pass through the through holes III 806. Finally, the nuts II 903 are screwed onto the bolts 902 to complete the installation of the camera.
