[0009] Furthermore, a welding nozzle assembly is plugged into the plug-in tube, and the welding nozzle assembly consists of a welding nozzle body, a connecting seat, a handle and a blocking rod, and the welding nozzle body is plugged into the plug-in tube.

[0010] Furthermore, a connecting seat is welded on the outer wall of the welding nozzle body, the connecting seat is an annular structure, and a handle is welded on the left side and the right side of the outer wall of the connecting seat.

[0011] Furthermore, the two handles are both L-shaped structures, and when the welding nozzle body is inserted into the mounting seat, the bottom end surfaces of the two handles are in contact with the top end surface of the mounting seat.

[0012] Furthermore, a cylindrical rod-shaped blocking rod is welded on the top surface of the mounting seat. When the welding nozzle body is inserted into the mounting seat, the rear end surface of a handle on the right side contacts the front end surface of the outer wall of the blocking rod.

[0013] Furthermore, a prompt structure is installed on the plug-in tube, and the prompt structure is composed of a contact rod, a mounting block, a contact switch and an indicator light. A contact rod with a cylindrical rod-shaped structure is welded on the right end face of the outer wall of the plug-in tube, and the right end of the contact rod is polished. After polishing, the right end of the contact rod is an arc-shaped structure; a mounting block is welded on the top surface of the mounting seat, and the mounting block is located on the right side of the plug-in tube. A contact switch is fixed on the right end face of the mounting block.

[0014] Furthermore, an indicator light is fixed on the top surface of the mounting seat, and the indicator light is electrically connected to the contact switch. When the contact switch is squeezed, the indicator light is energized. The contact switch is located to the left of the contact rod.

[0018] Compared with the prior art, the present invention has the following beneficial effects: In the present application, by setting a cooling component, on the one hand, after the cooling medium enters the annular tube, the annular tube can cool the welding nozzle body, thereby reducing the degree of wear of the welding nozzle body during use; on the other hand, when installing the welding nozzle body, the annular tube can limit the welding nozzle body and there is no need to repeatedly adjust the height of the welding nozzle body, thereby improving the installation efficiency of the welding nozzle body. In summary, in the present application, the cooling component can not only realize the cooling of the welding nozzle and ensure the service life of the welding nozzle, but also realize the limitation of the welding nozzle body during installation, thereby improving the installation efficiency of the welding nozzle body and having a flexible structure.

[0019] In the present application, through the setting of a microprocessor, a 4G module and an adjustment component, on the one hand, the staff operates the mobile terminal and sends a signal to the microprocessor through the 4G module. The microprocessor controls the motor to rotate for 3 seconds, and the motor drives the plug-in tube to rotate 180 degrees during 3 seconds; on the other hand, the motor drives the worm to rotate, and the worm wheel, the plug-in tube and the welding nozzle body rotate under the drive of the worm, and the angle adjustment of the welding nozzle body is completed at this time. In summary, the present application can be adjusted through intelligent control, and the adjustment is precise and efficient. In addition, the present application performs transmission adjustment through a worm gear, and there is no need to lock it separately after adjustment, which simplifies the operation.

[0020] In the present application, through the arrangement of the welding nozzle assembly, on the one hand, the welding nozzle body is inserted into the plug-in tube by pinching the two handles with both hands, and the welding nozzle body is quickly installed at this time; on the other hand, because the bottom end surfaces of the two handles are in contact with the top end surface of the mounting seat after the welding nozzle body is inserted into the mounting seat, the installation of the welding nozzle body can be completed when the bottom end surfaces of the two handles are in contact with the top end surface of the mounting seat. In summary, the handles can facilitate installation and achieve depth limitation during installation of the welding nozzle body, thereby improving installation efficiency and accuracy.

[0021] In the present application, through the setting of the prompt structure, when the welding nozzle body follows the rotation of the plug-in tube, the contact rod squeezes the contact switch, and the indicator light comes on. The staff can observe the indicator light to understand that the welding nozzle body is adjusted into place. If the indicator light is not on, the staff can find out in time and can adjust it manually after finding out, thus avoiding the phenomenon that the welding nozzle body cannot rotate into place.
