[0038] like Figure 2-5 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, both side walls of the fixing frame 2 are fixedly connected with a fixing rod 21, the outer wall of the fixing rod 21 is slidably connected with a linkage plate 22, the side wall of the linkage plate 22 is provided with a linkage groove 23, the side wall of the linkage plate 22 is also rotatably connected with a second connecting rod 24, the end of the second connecting rod 24 away from the linkage plate 22 is rotatably connected to the first connecting rod 122, the side wall of the mounting frame 1 is also rotatably connected with an adjusting screw 11, the outer wall of the adjusting screw 11 is provided with an external thread with opposite thread directions, and the adjusting screw 11 is threadably connected with the two groups of clamping rods 3 through two groups of external threads, and a turning handle is also provided at one end of the adjusting screw 11 to facilitate the rotation of the adjusting screw 11.

[0039] like Figure 2-4 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the drilling component includes a sliding frame 25 slidably connected to the outer wall of the fixed frame 2, a cylinder 251 fixedly connected to the top wall of the fixed frame 2 and a drilling device 252 fixedly connected to the side wall of the sliding frame 25, the output end of the cylinder 251 passes through the fixed frame 2 and is fixedly connected to the sliding frame 25, and the two side walls of the sliding frame 25 are fixedly connected with a linkage rod 253, and the linkage rod 253 is slidably connected to the linkage groove 23.

[0041] like Figure 1-5As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the fixed part includes a reinforcing rod 35 slidably connected to the middle part of the clamping rod 3, one end of the reinforcing rod 35 extruding the rod 32 is fixedly connected to the extrusion block 351, and the other end is fixedly connected to the clamping plate 352, and a limiting rod 353 is also provided on the outer wall of the reinforcing rod 35, and a tension spring 354 is also sleeved on the outer wall of the reinforcing rod 35, one end of the tension spring 354 is fixedly connected to the clamping plate 352, and the other end is fixedly connected to the clamping rod 3.

[0042] Specifically, when the drilling device for HVAC equipment installation is used: by rotating the adjusting screw 11, the distance between the two groups of clamping rods 3 is adjusted.

While the sliding frame 25 slides downward, the two sets of linkage plates 22 are pulled closer to each other through the linkage rod 253 and the linkage groove 23, and the vertical rod 12 is pressed to slide downward by setting the second connecting rod 24 and the first connecting rod 122. The first elastic member 123 is compressed, and the pull rod drives the extrusion rod 32 to slide downward through the pull rod, and presses the reinforcement rod 35 toward the pipeline direction through the extrusion block 351. The movement compresses the clamping plate 352 to be in close contact with the pipe, thereby fixing the pipe to ensure stability during the drilling process, and completing the drilling after the drilling equipment 252 contacts the pipe. When the cylinder 251 retracts, under the action of the first elastic member 123 and the tension spring 354, the vertical rod 12, the reinforcing rod 35, the extrusion rod 32, the extrusion block 351 and the clamping plate 352 are reset to contact and fix the pipe. By setting the walking wheel 341, the device can walk on the pipe when the drilling equipment 252 is not working, so as to adjust the position of the drilling hole, simplifying the fixing process and significantly improving the convenience of drilling.
