Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0035] Specifically, before use, water is first added to the micro water storage tank 19, and then the water tank cover 29 is tightened, and then the micro water pump 18 is started to work. The pumped water is connected to the input end of the water cooling head 20, and the pumped water is cooled inside, and then transmitted to the copper tube 6 through the output end of the water cooling head 20 for cooling, and then transported to the copper tube 2 7 through the connector 23, and the micro water pump 18 input end is pumped back. Because the micro water pump 18 may be accidentally damaged by workers when working, a protective shell 4 is fixedly connected to the top of the outer side of the cutting gun equipment 1, and a cover plate 3 is slidably connected to the top of the protective shell 4 to protect the micro water pump 18. Considering that the nozzle 25 may be damaged under uncertain time factors during use, a storage box 16 is fixedly connected to the front side of the top wall of the handle 12, and a cover plate 2 17 is slidably connected to the top of the storage box 16 to store spare nozzles 25, so that a new nozzle 25 can be replaced in time when the nozzle 25 is damaged.
[0036] Reference Figure 1 , Figure 2 and Figure 5The sliding telescopic mechanism 2 includes an elongated slider 201, the interior of the elongated slider 201 is slidably connected to the outer wall of the mixed gas pipe 9, a placement groove 206 is provided at the outer bottom of the elongated slider 201, a rotating column 205 is rotatably connected to the interior of the placement groove 206, the outer wall of the rotating column 205 is rotatably connected to the interior of the hollow rod 202, a contraction rod 207 is slidably connected to the interior of the hollow rod 202, a heating wire 203 is fixedly connected to the outer top of the contraction rod 207, a switch 204 is fixedly connected to the top of the outer wall of the elongated slider 201, an electric wire 11 is fixedly connected to the left side of the outer wall of the cutting gun device 1, a light bulb 10 is fixedly connected to the top of the electric wire 11, and anti-skid pads 13 are fixedly connected to the left and right sides of the outer wall of the handle 12, and the anti-skid pads 13 are threadedly connected to the screws 22;
[0037] Specifically, before using the machine, manually unscrew the oxygen valve 26 and the preheating oxygen valve 27 installed at the rear end of the outer side of the mixed gas pipe 9 to release the gas and then manually adjust the sliding telescopic mechanism 2 to adjust it. After the adjustment, the hollow rod 202 in the placement groove 206 is rotated out through the rotating column 205, and the contraction rod 207 fixed inside is pulled out, and the switch 204 is turned on to turn on the heating hot wire. After the heating wire 203 is heated and ignited, the switch 204 is pressed to turn it off, and the machine slides to the rear end area for cooling. Considering that the workers work in an environment with poor lighting conditions and cannot see the cutting situation in time, resulting in deviations in the cut objects, the left side of the outer wall of the cutting gun equipment 1 is fixedly connected with an electric wire 11, and the top of the electric wire 11 is fixedly connected with a light bulb 10 for auxiliary lighting. When working for a long time, the workers may accidentally slip their hands due to fatigue, so the left and right sides of the outer wall of the handle 12 are fixedly connected with anti-skid pads 13, and the anti-skid pads 13 are threadedly connected with the screws 22 to reduce the dangers of hand slips to the workers.
[0038] Reference Figure 1 , Figure 3 and Figure 4 A hook 14 is fixedly connected to the rear side of the outer wall of the grip 12, a protective cover 8 is installed on the outer wall of the nozzle 25, and a sealing ring 24 is fixedly connected to the outer walls of the cutting oxygen tube 5 and the mixed gas tube 9, and a filter 15 is fixedly connected to the inside of the sealing ring 24;
[0039] Specifically, after work, the hook 14 can be fixedly connected to the rear side of the outer wall of the handle 12, and the cutting gun equipment 1 can be hung on a wall or other places to prevent it from being damaged. When the machine is not in use, dust or other objects that may endanger the use of the nozzle 25 may enter the nozzle 25, so a protective cover 8 is installed on the outer wall of the nozzle 25 to protect the nozzle 25. When the equipment is in use, the pipeline connection may loosen after long-term use, resulting in gas leakage. Therefore, a sealing ring 24 is fixedly connected to the outer walls of the cutting oxygen pipe 5 and the mixed gas pipe 9, and a filter 15 is fixedly connected to the inside of the sealing ring 24 to filter impurities in the gas to ensure the stability of the flame during operation.
[0040] Working principle: Before using the equipment, manually unscrew the water tank cover 29 threaded on the top wall of the outer side of the micro water storage tank 19, add water, tighten the water tank cover 29 after adding water, and then start the micro water pump 18 to work. Because the micro water pump 18 has two working ends, the input end is connected to the bottom of the outer side of the micro water storage tank 19 for pumping water, and the output end is connected and fixedly connected to the input end of the water cooling head 20. The pumped water is cooled inside, and then transmitted to the copper tube 6 through the output end of the water cooling head 20 for cooling. When the water inside the copper tube 6 reaches the top, it is transported to the micro water pump 18 in the copper tube 2 7 through the connector 23, and the pumping is carried out to realize the circulation process, thereby realizing the effect of cooling the pipeline.
[0041] Before the machine works, manually unscrew the oxygen valve 26 installed on the top of the outer wall of the cutting gun equipment 1 and the preheating oxygen valve 27 installed on the outer rear end of the mixed gas pipe 9 to release the gas, and then manually slide the sliding telescopic mechanism 2 connected to the outer wall of the mixed gas pipe 9 to adjust the appropriate length. After the adjustment, the hollow rod 202 inside the placement groove 206 set at the bottom of the outer side of the long slider 201 is rotated out through the rotating column 205, and the contraction rod 207 fixed inside is pulled out, and finally the heating is turned on by the switch 204 fixedly connected to the top of the outer wall of the long slider 201. After the heating wire 203 is heated and ignited, the switch 204 is pressed to turn it off and slide it to the rear end area for cooling. After waiting for the temperature of the heating wire 203 to drop, the contraction rod 207 is retracted into the hollow rod 202, rotated and placed in the placement groove 206, and slid to the rear end, away from the high temperature area, thereby reducing the loss of the ignition device caused by the high temperature.
[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
