[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figure 1 - Figure 4 As shown, this utility model provides an easy-to-replace bakelite nozzle, including a nozzle assembly 1. The nozzle assembly 1 includes a nozzle head 11, one end of which is fixedly connected to a connecting plate 12. One end of the connecting plate 12 is fixedly connected to a connecting rod 13. A rod assembly 3 is installed on the outside of the connecting rod 13. The rod assembly 3 includes a connecting platform 32. One end of the connecting platform 32 has a connecting groove 33. One end of the connecting rod 13 is inserted into the inside of the connecting groove 33. A replacement mechanism 2 is installed on the outside of the connecting rod 13. The replacement mechanism 2 includes an elastic piece 28. One end of the elastic piece 28 is fixedly connected to a fixing push block 26. One end of the connecting platform 32 has a first mounting groove 22. One end of the elastic piece 28 is inserted into the inside of the first mounting groove 22. A second mounting groove 27 is opened inside the connecting platform 32. A first deformable push block 24 is fixedly connected inside the second mounting groove 27. One end of the first deformable push block 24 abuts against one end of the fixing push block 26.

[0024] Insert the connecting rod 13 into the connecting groove 33. The inner wall of the first mounting groove 22 contacts the inclined side of the fixed push block 26. Push the fixed push block 26 toward the connecting rod 13. The elastic sheet 28 deforms. The elastic sheet 28 and the fixed push block 26 are inserted into the corresponding positions inside the first mounting groove 22. The deformed elastic sheet 28 returns to its original position. The fixed push block 26 is engaged at one end of the first mounting groove 22, fixing the connecting rod 13. By pressing one end of the first deformable push block 24 inward, the first deformable push block 24 deforms, causing the other end of the first deformable push block 24 to push the fixed push block 26 toward the connecting rod 13. The elastic sheet 28 deforms, thereby removing the connecting rod 13 outward. This allows the nozzle assembly 1 to be removed for replacement. Replacement can be completed quickly. After installation, it provides a stable connection and will not loosen or fall off due to slight vibration, ensuring the accuracy and stability of the operation.

[0025] Example 2: Figure 1 - Figure 4 As shown, a positioning block 21 is fixedly connected to one end of the connecting plate 12, and a positioning groove 23 is opened at one end of the connecting platform 32. One end of the positioning block 21 is inserted into the inside of the positioning groove 23. A sealing ring 25 is fixedly connected to one end of the connecting plate 12. A cylindrical rod 31 is installed at one end of the connecting platform 32. A second suction hole 34 is opened in the middle of the cylindrical rod 31 and the middle of the connecting platform 32. A first suction hole 14 is opened in the middle of the suction nozzle 11 and the middle of the connecting rod 13. The second suction hole 34 communicates with the first suction hole 14.

[0026] The overall effect of this embodiment is that when the connecting rod 13 is inserted into the connecting groove 33, the positioning block 21 contacts the positioning groove 23 and is inserted into the positioning groove 23. This can position and guide the installation of the nozzle assembly 1 and the rod assembly 3, ensuring that the position of the nozzle assembly 1 is fixed. After the nozzle assembly 1 is installed at one end of the rod assembly 3, the sealing ring 25 seals the connection between the connecting rod 13 and the connecting groove 33 to prevent air leakage and insufficient suction.

[0027] The method for using and the working principle of the device are as follows: the connecting rod 13 is inserted into the inside of the connecting groove 33, the inner wall of the first mounting groove 22 is in contact with the oblique edge of the fixed push block 26, the elastic sheet 28 is deformed, the elastic sheet 28 and the fixed push block 26 are inserted into the corresponding positions in the inside of the first mounting groove 22, the deformed elastic sheet 28 is restored, the fixed push block 26 is clamped into one end of the first mounting groove 22, the connecting rod 13 is fixed, in the process of inserting, the positioning block 21 is in contact with the positioning groove 23, is gradually inserted into the inside of the positioning groove 23, the installation of the suction nozzle assembly 1 and the rod part assembly 3 can be positioned and guided, the sealing ring 25 seals the connecting position of the connecting rod 13 and the connecting groove 33, one end of the first deformed push block 24 is pressed inwards, the other end of the first deformed push block 24 pushes the fixed push block 26 to move to the connecting rod 13, the elastic sheet 28 is deformed, the connecting rod 13 can be taken out outwardly, and the suction nozzle assembly 1 can be taken down and replaced.

[0028] The above is only a preferred embodiment of the present application, and does not limit the present application in other forms. Any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields. However, any simple modification, equivalent change and modification made according to the technical essence of the present application to the above embodiments still belong to the protection scope of the present application.
