Positioning assembly 8, one end of the two L-shaped rods 72 are fixedly connected to the top and bottom of the inner wall of the U-shaped frame 73 respectively, the other ends of the two L-shaped rods 72 are fixedly connected with push blocks 74, the top and bottom of the recessed part of the exhaust gas collecting port 6 are provided with second slide grooves 75, the interior of the second slide grooves 75 is slidably connected with two front and rear sliders 76, and a return spring 78 is fixedly connected between the two sliders 76, the tops of the two sliders 76 are fixedly connected with contact blocks 77, the tops of the two contact blocks 77 are rotatably connected with connecting rods 79, the other ends of the two connecting rods 79 are rotatably connected with pressure plates 710 in a horizontal position, and a sealing ring 711 is provided on the left side of the U-shaped frame 73 through a slot, and the shape of the sealing ring 711 is U-shaped.

[0025] When installing the exhaust gas collecting port 6, it is only necessary to push the U-shaped frame 73 to quickly complete the installation of the exhaust gas collecting port 6 without drilling a large number of bolt holes, thereby improving the practicability of the device when in use.

[0026] like Figure 3 and 4 The second embodiment is shown, and the main difference from the first embodiment is that the positioning assembly 8 includes two upper and lower sliding bars 81, and the two sliding bars 81 are slidably connected to the inner surfaces of the upper and lower first sliding grooves 71 respectively, and one end of the two sliding bars 81 is fixedly connected to the left sides of the upper and lower L-shaped rods 72 respectively, and a plurality of limit blocks 82 are fixedly connected to the opposite sides of the two sliding bars 81 at equal distances, and a fixing rod 83 is fixedly connected between the front and back sides of the inner wall of the first sliding groove 71, and the surface of the fixing rod 83 is rotatably connected to the front and rear rotating blocks 84, and the tops of the two rotating blocks 84 are fixedly connected to the limiting pressure plate 85, and the head of the limiting pressure plate 85 is provided with a limiting tooth block that cooperates with the limit block 82, and the surface of the fixing rod 83 located between the opposite sides of the two rotating blocks 84 is sleeved with a torsion spring 86, one end of the torsion spring 86 is fixedly connected to the surface of the limit block 82, and the other end of the torsion spring 86 is fixedly connected to the bottom of the limiting pressure plate 85.
