[0024] Please refer to Figures 1-3 , a fine-tunable exhaust pipe positioning fixture provided by the present invention includes an operating table 1.

[0025] Referring to Figure 1 and Figure 2 As shown, a reinforcement structure 2 is installed on the top surface of the operating table 1. The reinforcement structure 2 includes a base 201, a first slider 202, a first connecting rod 203, a second connecting rod 204, a connecting shaft 205, a handle 206, and a positioning pin 207. The bottom ends of the bases 201 are all installed on the top surface of the operating table 1. First sliders 202 are provided on the inner walls of the bases 201. First connecting rods 203 are installed on the opposite sides of the first sliders 202. A second connecting rod 204 is installed on the opposite sides of the first connecting rods 203. A connecting shaft 205 is installed at the middle position of the second connecting rod 204. A handle 206 is installed at the bottom of the connecting shaft 205. A positioning pin 207 penetrates through the inside of the side of the handle 206 away from the connecting shaft 205. The base 201 is slidably connected to the first slider 202. The first slider 202 is connected to the first connecting rod 203 by a shaft. The first connecting rod 203 is connected to the second connecting rod 204 by a shaft. The positioning pin 207 extends into the operating table 1 and is not connected to it.

[0026] When the positioning pin 207 is placed outside the handle 206, turning the handle 206 can quickly adjust the distance between the first sliders 202. Rotate to the corresponding position according to the thickness of the exhaust pipe, and insert the positioning pin 207 to make the distance between the first sliders 202 stable. Thus, during the process of detecting or repairing the exhaust pipe, the exhaust pipe will not change its position due to operation, realizing the function of stabilizing the exhaust pipe of the device.

[0027] Referring to Figure 1 andFigure 3 As shown in the figure, an adjustment structure 3 is provided inside the operation table 1. The adjustment structure 3 includes a rack 301, a gear 302, a second slider 303, a third connecting rod 304, a limit block 305, a lower mounting block 306, a threaded rod 307, and a limit rod 308. The rack 301 penetrates inside the operation table 1. Gears 302 are provided on both sides of the rack 301. A second slider 303 is welded to the top surface of the gear 302. A third connecting rod 304 is provided outside the second slider 303. A limit block 305 is provided outside the third connecting rod 304. The third connecting rod 304 extends to the top end outside the operation table 1 and is installed with a lower mounting block 306. A threaded rod 307 is installed at the middle position of the top of the lower mounting block 306. Limit rods 308 are provided outside the threaded rod 307 inside the lower mounting block 306. The top ends of the limit rods 308 are fixed with an upper mounting block 309. The rack 301 abuts against the operation table 1 without connection. The rack 301 is meshed with the gear 302. The extended end at the bottom of the gear 302 abuts against the operation table 1 without connection. The gear 302 abuts against the third connecting rod 304 without connection. The second slider 303 is slidably connected to the third connecting rod 304. The third connecting rod 304 is slidably connected to the limit block 305. The limit block 305 is bolted to the operation table 1. The lower mounting block 306 is threadedly connected to the threaded rod 307. The lower mounting block 306 is slidably connected to the limit rod 308.

[0028] By pulling the rack 301, the distance between the lower mounting blocks 306 can be adjusted. By rotating the threaded rod 307, the distance between the lower mounting block 306 and the upper mounting block 309 can be adjusted, so as to be applicable to various exhaust pipes, realizing the function that the device can be applicable to the sizes of various exhaust pipes by adjusting the spacing.

[0029] In summary, as Figures 1-3 shown, when using this exhaust pipe positioning fixture, place the exhaust pipe between the lower mounting block 306 and the upper mounting block 309. Pull the rack 301. The rack 301 drives the gear 302 to rotate. The gear 302 drives the third connecting rod 304 to move outside the second slider 303 and inside the limit block 305, thereby driving the distance between the lower mounting blocks 306 to decrease or increase. Rotate the threaded rod 307. The threaded rod 307 drives the upper mounting block 309 to move downward, and at the same time drives the limit rod 308 to slide inside the lower mounting block 306. Pull out the positioning pin 207 and place the positioning pin 207 outside the handle 206. Rotate the handle 206. The handle 206 drives the connecting shaft 205 to rotate. The connecting shaft 205 drives the second connecting rod 204 to rotate. The second connecting rod 204 drives the first connecting rod 203 to move. The first connecting rod 203 drives the first slider 202 to slide inside the base 201, so as to facilitate adjusting the spacing of the first slider 202. After adjusting to the required position, insert the positioning pin 207, thereby stably installing exhaust pipes of different sizes.
