[0021] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. This utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Reference Figures 1-4 This utility model provides an adjustable-angle auxiliary nozzle support, including a U-shaped frame 1. Rotating blocks 9 are rotatably connected to the inner walls of both sides of the U-shaped frame 1. A square plate 2 is fixedly connected between the two rotating blocks 9 by bolts. A clearance opening 3 is provided on the square plate 2. A connecting post 19 is rotatably connected to the outer circumference of the clearance opening 3. The top of one of the connecting posts 19 passes through the upper surface of the square plate 2 and is provided with a fixing component for fixing the connecting post 19. An internally threaded tube 4 is welded between the two connecting posts 19. A nozzle body 8 is threadedly connected to the inner circumference of the internally threaded tube 4. The square plate 2 can be rotated within the U-shaped frame 1 by the provided U-shaped frame 1, so that the nozzle body 8 can be rotated in the vertical direction, thereby changing the angle of the nozzle body 8 in the vertical direction. Furthermore, the nozzle body 8 can be adjusted in the horizontal direction by the provided clearance opening 3 and internally threaded tube 4.

[0023] In this utility model, the fixing component includes a first connecting plate 10, which is fixedly connected to the extension end of one of the connecting posts 19 by bolts. The upper surface of the square plate 2 is provided with multiple slots 18. The first connecting plate 10 is provided with a through hole 17, and a rod 16 is slidably connected in the through hole 17. The top end of the rod 16 is welded with a second connecting plate 11, and the bottom end of the rod 16 is embedded in one of the slots 18. By using the fixing component, the rod 16 can be embedded into the corresponding slot 18, thereby adjusting the angle of the nozzle body 8 in the horizontal direction and fixing the connecting post 19, thereby fixing the angle of the nozzle body 8.

[0024] To further adjust the angle of the nozzle body 8, threaded rods 5 are bolted to the opposite sides of the two rotating blocks 9. One end of each threaded rod 5 extends through the outer walls of both sides of the U-shaped frame 1, and only the extended portion is threaded. Locking knobs 6 are threaded onto the outer circumference of the extended portion of each threaded rod 5. One side of the locking knob 6 is in close contact with the outer walls of both sides of the U-shaped frame 1. By using the threaded rods 5 and locking knobs 6, the locking knob 6 can be brought into close contact with one side of the U-shaped frame 1, thereby allowing the counterplate 2 to be pressed. After adjusting the angle of the nozzle body 8 in the vertical direction, it is fixed. The upper surface of the first connecting plate 10 is provided with a plurality of guide grooves 12 arranged in a circular array. Guide rods 13 are slidably connected in each of the plurality of guide grooves 12. The top ends of the plurality of guide rods 13 are fixed to the lower surface of the second connecting plate 11. Through the provided guide rods 13 and guide grooves 12, the second connecting plate 11 can be guided during the upward movement, thereby increasing the stability of the movement of the second connecting plate 11 and preventing deviation.

[0025] To limit the movement of the second connecting plate 11, limit grooves are formed on the outer circumferential walls of multiple guide grooves 12. Limit blocks 15 are slidably connected in multiple limit grooves, and the inner circumferential wall of the limit block 15 is fixed to the outer circumferential wall of the guide rod 13. The limit blocks 15 and limit grooves limit the upward movement distance of the second connecting plate 11, thereby preventing the guide rod 13 from detaching from the guide groove 12. A spring 14 is welded to the upper surface of the limit block 15, and the other end of the spring 14 is fixed to the top inner wall of the limit groove and springs back. Spring 14 is sleeved on the outside of guide rod 13. The spring 14 can make the second connecting plate 11 move upward and then fall down quickly for easy use. It also prevents the device from vibrating during use, which would cause the insertion rod 16 to lose contact with the slot 18 and cause the nozzle body 8 to rotate in the horizontal direction. Fixing blocks 7 are fixedly connected to the outer walls of both sides of the U-shaped frame 1 near the bottom by bolts. Both fixing blocks 7 have mounting holes. The device can be easily installed through the fixing blocks 7 and mounting holes.

[0026] The use of this utility model involves the following steps:

[0027] S1: When it is necessary to install the nozzle body 8, first thread the nozzle body 8 into the internal thread tube 4. When adjusting the angle in the horizontal direction, first pull the second connecting plate 11, which will drive the insertion rod 16 to move upward along the through hole 17. When the bottom end of the insertion rod 16 is disengaged from the slot 18, the internal thread tube 4 can be rotated to change the angle of the nozzle body 8 in the horizontal direction. After the adjustment is completed, release the second connecting plate 11 and let the insertion rod 16 move downward along the through hole 17 until its bottom end is embedded in one of the slots 18 to complete the angle adjustment of the nozzle body 8 in the horizontal direction.

[0028] S2: When it is necessary to adjust the vertical angle of the nozzle body 8, the angle of the nozzle body 8 in the vertical direction can be adjusted by rotating the square plate 2 so that it rotates within the U-shaped frame 1. After the adjustment is completed, the angle adjustment of the nozzle body 8 in the vertical direction can be completed by rotating the locking knob 6 so that one side of it is in close contact with the outer wall of one side of the U-shaped frame 1.

[0029] Finally, the following points should be noted: In the description of this application, it should be noted that, unless otherwise specified and limited, the terms "installation", "connection" and "linkage" should be interpreted broadly, and can be mechanical or electrical connection, or internal connection between two components, or direct connection. "Up", "down", "left", "right", etc. are only used to indicate relative positional relationship. When the absolute position of the described object changes, the relative positional relationship may change.
