[0027] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] Embodiment 1 of this utility model: as follows Figures 1-5As shown, a nozzle adjustment bracket includes a first connector 1, a second connector 2, and a connector 3. Two first connecting arms 4 are fixedly installed at one end of the first connector 1. Specifically, the first connecting arms 4 can be fixedly connected to the first connector 1 by welding, gluing, or integral molding. The connector 3 is rotatably installed between the two first connecting arms 4. Here, the connector 3 is taken as a ring, but in actual use, the shape of the connector 3 can also be cross-shaped, rectangular, etc. A first driving member 5 is provided on one of the first connecting arms 4, and the first driving member 5 is connected to the connector 3 in a transmission manner. The first driving member 5 can drive the connector 3 to rotate relative to the first connecting arm 4.

[0029] Two second connecting arms 6 are fixedly installed at one end of the second connector 2. Specifically, the second connecting arms 6 can be fixedly connected to the second connector 2 by welding, gluing, or integral molding. The end of the second connecting arm 6 away from the second connector 2 is rotatably connected to the connector 3. The rotation center line of the second connecting arm 6 and the connector 3 intersects with the rotation center line of the connector 3 and the first connecting arm 4. One of the second connecting arms 6 is provided with a second driving member 7, which is connected to the connector 3 in a transmission manner. The two first connecting arms 4 are symmetrically arranged about the first connector 1; the two second connecting arms 6 are symmetrically arranged about the second connector 2. The two first connecting arms 4 and the first connector 1 form a Y-shaped structure or a U-shaped structure, and the two second connecting arms 6 and the second connector 2 form a Y-shaped structure or a U-shaped structure.

[0030] In a preferred embodiment, the connector 3 is a circular ring. A first rotating shaft 31, a second rotating shaft 32, a third rotating shaft 33, and a fourth rotating shaft 34 are fixedly mounted on the outer surface of the ring. These shafts are evenly distributed along the circumference of the ring, with the first rotating shaft 31 and the third rotating shaft 33 facing each other, and the second rotating shaft 32 and the fourth rotating shaft 34 facing each other. The first rotating shaft 31 is rotatably connected to a first connecting arm 4, and the third rotating shaft 33 is rotatably connected to another first connecting arm 4. The second rotating shaft 32 is rotatably connected to a second connecting arm 6, and the fourth rotating shaft 34 is rotatably connected to another second connecting arm 6.

[0031] The second connector 2 has a connecting tube 8 inside, with both ends of the connecting tube 8 extending out of the second connector 2. In specific implementations, the connecting tube 8 can be detachably connected to the second connector 2, or it can be fixedly connected by threads, etc. The end of the connecting tube 8 away from the annulus is used to install the nozzle, and the other end of the connecting tube 8 is connected to the flexible conduit 9. The end of the flexible conduit 9 away from the connecting tube 8 is connected to the liquid supply device. The end of the first connector 1 away from the first connecting arm 4 is fixedly connected to a connecting rod 10.

[0032] In one implementation, both the first drive unit 5 and the second drive unit 7 are servo motors. The housing of the servo motor of the first drive unit 5 is fixedly connected to the corresponding first connecting arm 4, and the output shaft of the servo motor is fixedly connected to the corresponding first rotating shaft 31. The axis of the output shaft of the servo motor coincides with the axis of the first rotating shaft 31.

[0033] The housing of the servo motor in the second drive unit 7 is fixedly connected to the corresponding second connecting arm 6, and the output shaft of the servo motor is fixedly connected to the corresponding second rotating shaft 32, with the axis of the output shaft of the servo motor coinciding with the axis of the second rotating shaft 32. In practical applications, the servo motor model can be selected as TD-9412MG servo motor according to actual needs.

[0034] In practical use, cleaning fluid, medicine or paint is supplied to the nozzle through the flexible conduit 9 via the liquid supply device. The first drive 5 drives the connector 3 to rotate between the two first connecting arms 4. The second drive 7 drives the second connecting arm 6 to rotate relative to the connector 3. In this way, the spray angle of the nozzle can be adjusted arbitrarily as needed to achieve a wider spray coverage without the need to move the entire machine.

[0035] To avoid interference from the flexible guide tube 9 when adjusting the nozzle spray angle, and also to make the entire adjustment bracket look neater and more aesthetically pleasing, the following measures can be taken:

[0036] A channel 101 is formed inside the connecting rod 10 along the axial direction; the flexible conduit 9 passes sequentially through the inner ring of the annulus, the first connector 1, and the channel 101 to connect with the liquid supply device, such as... Figure 1 As shown.

[0037] refer to Figures 3-5 As shown, to facilitate the installation of the connecting rod 10, the first connector 1 has a mounting hole 11, which penetrates the first connector 1. The two first connecting arms 4 are symmetrical about the axis of the mounting hole 11. One end of the connecting rod 10 is installed in the mounting hole 11.

[0038] To facilitate nozzle installation, different nozzle models can be replaced according to spraying needs. A quick-release connector 12 is installed at the end of the connecting pipe 8 away from the annulus, and the connecting pipe 8 is connected to the nozzle through the quick-release connector 12. The quick-release connector 12 is existing technology and will not be described in detail here.

[0039] This utility model also discloses an aircraft, including the nozzle adjustment bracket as described above. The aircraft can be a drone; taking a drone as an example, during installation, the end of the connecting rod 10 of the nozzle adjustment bracket away from the first connecting head 1 is fixed to the drone, such as to the drone's arm. To facilitate the flexible conduit 9 passing through the connecting rod 10 and connecting to the liquid supply device on the drone, an exit hole can be opened at the end of the connecting rod 10 near the drone. The end of the flexible conduit 9 away from the first connecting head 1 passes through the exit hole and connects to the liquid supply device. During spraying operations, the spray angle of the nozzle is adjusted by the first driving component 5 and the second driving component 7, resulting in a wider coverage area and no need for the aircraft to move, thus improving dynamic operation efficiency.
