[0033] Through the above technical scheme, the upper saddle 1 is installed at the required place of the gas main pipeline, and the terminal 25 is connected to the external circuit through the set electric heating wire (not shown in the figure), so that the electric heating wire (not shown in the figure) heats the upper saddle 1 and the gas main pipeline to melt the joint, and then fuses after cooling to achieve the effect of preventing gas leakage, and then the rotating cap 24 is rotated to rotate the screw 22 to drive the drilling tool 23 to rotate and move downward in the upper through pipe 2, so that the drilling tool 23 drills the gas main pipeline. When the drilling tool 23 moves downward, the sealing plate 28 slides downward and fits the sealing rubber pad 27. The sealing rubber pad 27 first contacts the sealing rubber pad 27, and then the drilling tool 23 contacts the gas main pipeline to drill a hole. When the drilling tool 23 drills downward, the sealing plate 28 resists and squeezes the sealing rubber pad 27. The characteristics of the sealing rubber pad 27 can be compressed to a certain extent, so when drilling, the gas will not leak out of the main pipeline, which greatly facilitates installation and use.

[0038] In actual operation, when the device is in use, the upper saddle 1 is installed at the required location of the gas main pipeline, and the terminal 25 is connected to the external circuit through the provided electric heating wire (not shown in the figure), so that the electric heating wire (not shown in the figure) heats the upper saddle 1 and the gas main pipeline to melt the joint, and then fuses after cooling to achieve the effect of preventing gas leakage, and then the rotating cap 24 is rotated to rotate the screw 22 to drive the drilling cutter 23 to rotate and move downward in the upper through pipe 2, so that the drilling cutter 23 drills a hole in the gas main pipeline. When the drilling cutter 23 moves downward, the sealing plate 28 slides downward and fits the sealing rubber pad 27. The sealing rubber pad 27 first contacts the sealing rubber pad 27, and then the drilling cutter 23 contacts the gas main pipeline to drill a hole. When the drilling cutter 23 drills downward, the sealing plate 28 resists and squeezes the sealing rubber pad 27. The characteristics of the sealing rubber pad 27 can be compressed, so when drilling, the gas will not leak out of the main pipeline, which greatly facilitates installation and use.
