[0034] Reference Figure 2-4 The buckle assembly includes eight card slots 11, which are respectively opened on the rear side of the connecting disk 2 and the front side of the water cooling jacket 3. The connecting disk 2 and the water cooling jacket 3 are used to provide an opening space for the card slots 11. The oxygen gun seat 1 and the connecting disk 2 5 are fixedly connected with four shells 12 inside. The oxygen gun seat 1 and the connecting disk 2 5 are used to support and fix the shell 12. The inside of the shell 12 is fixedly connected with a pressure rod 13, and the shell 12 is used to limit the pressure rod 13. The outside of the pressure rod 13 is fixedly connected with a pressure plate 14, and the pressure rod 13 is used to drive the pressure plate 14 to move.

The opposite sides of the two blocks 19 are designed to be triangles, which can facilitate the engagement of the blocks 19 with the slots 11.

[0037] Working principle: when in use, water is supplied to the inside of the water cooling jacket 3 by connecting the water inlet pipe 6 to the water supply pipe, and then the water inside the connection plate 2 is discharged by connecting the water outlet pipe 7 to the drain pipe, so that the heat generated by the oxygen gun core 4 can be brought out by the water flow, thereby realizing water cooling and heat dissipation of the multifunctional furnace wall oxygen gun when in use, and being able to maintain the multifunctional furnace wall oxygen gun in a stable state, avoiding damage easily caused by high-load operation, extending the service life, and reducing the processing cost. When replacing the connection plate 2 or repairing the internal parts of the multifunctional furnace wall oxygen gun, it is only necessary to press the pressure rod 13. The pressure rod 13 drives the offset rod 15 to move through the pressure plate 14 under the limit of the support rod 20, and then drives the spring 17 to move through the slider 16, thereby driving the two blocks 19 to move relative to each other and not being able to engage with the card slot 11, and the connection can be easily removed. The disk 12 and the water-cooling jacket 3 only need to correspond the card block 19 to the corresponding card slot 11 during installation, and insert the card block 19 into the card slot 11. When the triangular inclined surface of the card block 19 contacts the outer wall of the card slot 11, it will be squeezed to move relative to the card slot 11, thereby driving the slider 16 to move and squeeze the spring 17 through the pull rod 18. When the card block 19 completely enters the card slot 11, the spring 17 pushes the slider 16 to move, thereby driving the card block 19 to move and engage with the card slot 11 through the pull rod 18. At the same time, the two sealing rings provided on the oxygen gun seat 1 will be respectively inserted into the sealing groove 19 and the sealing groove 2 10, and the installation can be completed, so that the water-cooling jacket 3 can be easily disassembled, so that the water-cooling jacket 3 can be easily replaced and cleaned, and the internal repair and maintenance of the multi-functional furnace wall oxygen gun can also be convenient, thereby improving practicality.
