[0030] As Figure 1 shown, it is the copper nozzle fixing device 100 shown in the present utility model, which is installed on a spectacle frame riveting hinge machine, and the copper nozzle fixing device 100 is used to fix the copper nozzle 101.
[0031] As Figures 1 to 2 shown, the copper nozzle fixing device 100 includes: a heat-conducting seat 10, a positioning member assembly 20 and an elastic member 30. Among them, the heat-conducting seat 10 is used to place the copper nozzle 101, the positioning member assembly 20 is slidably connected to the heat-conducting seat 10, and the elastic member 30 is used to provide the elastic force for the positioning member assembly 20 to be inserted into the copper nozzle 101.

The heat conducting base 10 is provided with a mounting hole 11 and a guiding hole 12. The mounting hole 11 is used for mounting the copper nozzle 101. The guiding hole 12 communicates with the mounting hole 11, and the guiding hole 12 and the mounting hole 11 are perpendicularly arranged. The positioning member assembly 20 is slidably connected to the guiding hole 12 and is inserted into the positioning groove 102.
[0034] Specifically, as Figure 3 shown, the positioning member assembly 20 includes a limiting member 21 and an actuating member 22. The limiting member 21 is slidably connected to the guiding hole 12. The actuating member 22 is connected to one end of the limiting member 21 away from the mounting hole 11. Among them, the limiting member 21 includes a top head 211 and a guide rod 212. The top head 211 is arranged in cooperation with the positioning groove 102. One end of the guide rod 212 is connected to the top head 211, and the other end of the guide rod 212 is connected to the actuating member 22. In order to improve the positioning accuracy of the copper nozzle 101, as Figure 2 shown, the top head 211 is provided with a conical portion 213 in a conical shape. The positioning groove 102 is a V-shaped groove. Through the cooperation of the conical portion 213 and the V-shaped groove, it is beneficial to position the copper nozzle 101 through the conical portion 213 of the top head 211, so as to achieve the purpose of improving the positioning accuracy of the copper nozzle 101.

The guide rod 212 of the limiting member 21 is rotatably connected to the transfer rod 222. During use, when the first limiting surface 223 contacts the heat conducting base 10, the top head 211 of the limiting member 21 is inserted into the mounting hole 11 under the push of the elastic member 30. When the second limiting surface 224 contacts the heat conducting base 10, the top head 211 of the limiting member 21 is located in the guiding hole 12 for the copper nozzle 101 to be inserted into the mounting hole 11.
[0036] As Figure 1 shown, the heat conducting base 10 is further provided with a receiving groove 13 and a guiding groove 14. The actuating member 22 is arranged in the receiving groove 13.

[0038] AsFigure 3 As shown, the elastic member 30 is a spring and is sleeved on the guide rod 212 to provide the elastic force for the top head 211 to insert into the mounting hole 11.
[0039] The working principle of the copper nozzle fixing device 100 of the present utility model is as follows: Apply a pulling force to the positioning member assembly 20 away from the mounting hole 11, so that the elastic member 30 is compressed by the force. Insert the copper nozzle 101 into the mounting hole 11 of the heat conducting seat 10. Stop applying the pulling force. The elastic force provided by the elastic member 30 pushes the positioning member assembly 20 to slide in the guiding hole 12 of the heat conducting seat 10 towards the mounting hole 11 and insert into the positioning groove 102 of the copper nozzle 101 inserted into the mounting hole 11. Utilize the cooperation between the positioning member assembly 20 and the positioning groove 102 of the copper nozzle 101 to fix the copper nozzle 101 in the mounting hole 11 of the heat conducting seat 10, thus realizing the installation and fixation of the copper nozzle 101.
