[0002] With the rapid development of the industrial field, the performance and accuracy of the oil nozzle as a key component in the lubrication system are crucial to ensure the efficient and stable operation of mechanical equipment. However, the traditional oil nozzle design often has problems such as limited adjustment range and difficulty in replacement, which cannot meet the needs under different working conditions. Therefore, a replaceable and adjustable oil nozzle came into being;

[0003] A replaceable and adjustable nozzle device with publication number CN214727866U includes a material guide gun barrel, a spray gun discharge gun nozzle, a gun nozzle adjustment nut and a sealing ring. One end of the gun nozzle adjustment nut is threadedly connected to the material guide gun barrel, and the other end of the gun nozzle adjustment nut is threadedly connected to the spray gun discharge gun nozzle. One end of the spray gun discharge gun nozzle extends into the material guide gun barrel, and the sealing ring is located between the spray gun discharge gun nozzle and the material guide gun barrel. The gun nozzle bracket is connected to the gun nozzle by a threaded and detachable gun nozzle connecting nut. The gun nozzle can be extended or disassembled and replaced by simply rotating the gun nozzle. A sealing ring is arranged between the gun nozzle and the gun nozzle bracket, and a sealing effect can be achieved regardless of the gun nozzle being extended or moved to any position. The overall device is easy to adjust and use, has more optimized performance, and has wide adaptability.

[0004] When the oil nozzle is in use, it needs to spray oil in different directions according to different use environments. When the nozzle device in the above-mentioned prior art is in use, the nozzle spraying direction is fixed and inconvenient to adjust, which in turn limits the scope of use during use, resulting in reduced flexibility of use. Therefore, corresponding improvements are needed. Utility Model Content
