[0027] The mounting ring 2 is slidably connected to the inside of the mounting groove 11, and a pair of horizontal corresponding second slide grooves 21 are opened on both sides of the upper end surface of the mounting ring 2. The second slide grooves 21 are slidably connected to the inside of the second slide grooves 21, and the inner sides of the second slide blocks 22 are fixedly connected to the first springs 23. The first spring 23 is fixedly connected to one side of the inside of the second slide groove 21. A bottom ring 24 is provided directly below the mounting ring 2, and a bottom plate 25 is fixedly connected to the lower end surface of the bottom ring 24;

[0028] The interior of the first slide groove 12 fits with the first slider 13, the first slider 13 is in an arc shape, the interior of the second slide groove 21 fits with the second slider 22, the second slider 22 is in an arc shape, the second slider 22 can fit with the interior of the first slide groove 12, the mounting ring 2 fits with the interior of the mounting groove 11, the inner side of the first slide groove 12 is communicated with the outer wall of the mounting groove 11, the other side of the first slide groove 12 is communicated with the outside of the fixing ring 1, the transparent protective wall 4 is located at the periphery of the nozzle 16, a welding gun is provided outside the nozzle 16, and one end of the nozzle 16 is fixedly connected to the output end of the welding gun;

[0029] In the specific implementation process, Figure 2 and Figure 3 When the mounting ring 2 is removed, the first slider 13 is manually pressed so that the first slider 13 pushes the second slider 22 into the second slot 21 and the mounting ring 2 is pulled out. By pressing the second slider 22, the mounting ring 2 is inserted into the mounting slot 11. The second slider 22 is pushed into the first slot 12 by the first spring 23 to complete the fixing. When disassembling, it is only necessary to press the first slider 13 to achieve quick installation and disassembly of the mounting ring 2, which is convenient for later maintenance.

[0030] Embodiment 2: In embodiment 1, there are still problems. Therefore, based on embodiment 1, this embodiment further includes:

[0031] In the specific implementation process, Figure 1 and Figure 5 As shown, the outer wall of the bottom plate 25 is slidably connected with a plurality of movable plates 3, and the plurality of movable plates 3 are combined into a circular ring shape.
