When the exhaust pipe body 15 is tested for sealing, it needs to be placed between two groups of curved plates 14, and the hydraulic cylinders 12 on both sides are started to push the connecting rod 13, so that the two groups of curved plates 14 and the exhaust pipe body 15 abut and form a clamp, so as to achieve a fixing effect during the testing process;

[0027] The adjusting mechanism includes a sleeve plate 2, which is fixedly connected to the surface of the bracket base 1. A movable groove 21 and a screw hole 24 are opened on the surface of the sleeve plate 2. A short screw 22 is fixedly connected to the surface of the mounting plate 11. A first nut 23 is installed on the surface of the short screw 22. A fastening screw 25 is threadedly connected to the surface of the screw hole 24. A twisting block 26 is fixedly connected to the surface of the fastening screw 25. Under the action of the sleeve plate 2, the length of the mounting plate 11 is extended, so that when the sealing of the exhaust pipe body 15 is tested, the space is not restricted when it is installed on the arc plate 14, and it can be adjusted and adapted according to the size of the exhaust pipe body 15 or the height of the detection device.

[0028] Furthermore, the mounting plate 11 is slidably connected to the inner surface of the sleeve plate 2, two groups of movable grooves 21 are provided, and the two groups of movable grooves 21 are opened on both sides of the sleeve plate 2, and two groups of short screws 22 are provided. The short screws 22 are slidably connected to the surface of the movable grooves 21, and the inner surface size of the sleeve plate 2 is the same as the size of the mounting plate 11. The side surfaces of the mounting plate 11 all slide in the sleeve plate 2, and under the action of the two groups of movable grooves 21, the position of the arc plate 14 can be moved, thereby achieving the effect of adjustment.

[0029] Furthermore, two groups of short screws 22 are installed on both sides of the mounting plate 11, one end of the short screw 22 is fixedly connected to the surface of the mounting plate 11, and the other end of the short screw 22 is threadedly connected to the surface of the first nut 23, and the first nut 23 is abutted and connected to the outer surface of the sleeve plate 2. Under the connection between the short screw 22 and the first nut 23, the position of the moving mounting plate 11 is limited, thereby making the connection between the sleeve plate 2 and the mounting plate 11 more secure.

[0030] Furthermore, one end of the fastening screw 25 is abutted and connected to the surface of the mounting plate 11, and the other end of the fastening screw 25 is fixedly connected to the surface of the twisting block 26. The cross-section of the twisting block 26 is circular. Through the connection between the fastening screw 25 and the twisting block 26, the mounting plate 11 can be moved by twisting the twisting block 26 so that the fastening screw 25 can abut and limit the moved mounting plate 11, thereby achieving the purpose of preliminary limiting.

[0031] Furthermore, a fastening mechanism is provided on the surface of the exhaust pipe body 15, and the fastening mechanism includes an abutment plate 3, which is abutted and connected to the surface of the exhaust pipe body 15, and a movable hole 31 is opened on the surface of the abutment plate 3. A long screw 32 is fixedly connected to the surface of the bracket base 1, and a second nut 33 is threadedly connected to the surface of the long screw 32. Under the action of the abutment plate 3, the two ends of the exhaust pipe body 15 can be further fixed and limited.

[0032] Furthermore, two groups of abutment plates 3 are provided, and the two groups of abutment plates 3 are arranged at both ends of the exhaust pipe body 15. The number of abutment plates 3 in each group is two, and each group of abutment plates 3 is abutted and connected on both sides of the exhaust pipe body 15. Two groups of movable holes 31 are provided, and the two groups of movable holes 31 are opened at both ends of the abutment plates 3. The abutment plates 3 are connected with the long screw rod 32 through the movable holes 31, so that the abutment plates 3 can move along the direction of the long screw rod 32.

[0033] Furthermore, two groups of long screws 32 are provided, and the two groups of long screws 32 are arranged on both sides of the abutment plate 3. Two groups of second nuts 33 are provided, and the two groups of second nuts 33 are arranged on both sides of the long screws 32. The second nuts 33 are abutted and connected to the surface of the abutment plate 3. The size of the second nuts 33 is larger than the size of the movable hole 31. The two groups of second nuts 33 are arranged on the outer sides of the two abutment plates 3. The long screws 32 and the second nuts 33 are connected to achieve the effect of the abutment of the exhaust pipe body 15 by the abutment plate 3.

[0034] Working principle: Before testing, move the mounting plate 11 to make it slide on the inner surface of the sleeve plate 2. When it is moved to a height that matches the exhaust pipe body 15 and the detection device, turn the screw block 26 so that the fastening screw 25 is connected through the thread and the screw hole 24 and finally abuts against the mounting plate 11, so as to achieve the effect of initially limiting the mounting plate 11. At this time, the first nuts 23 on both sides are screwed through the threads to make them abut against the outer surface of the sleeve plate 2, so as to achieve the purpose of limiting and fixing the moving mounting plate 11.

[0035] When testing exhaust pipe bodies 15 of different specifications, first place them between two groups of arc plates 14, and then place the two ends between each group of abutment plates 3. At the same time, the second nuts 33 on both sides of the long screw 32 are threadedly rotated to the two ends. When the exhaust pipe body 15 abuts against the arc plate 14 through the action of the hydraulic cylinder 12, the abutment plate 3 is slid along the surface of the long screw 32 through the movable hole 31 until it fits with the exhaust pipe body 15. At this time, the second nut 33 is threadedly rotated again to abut against the abutment plate 3, thereby achieving the effect of abutting the exhaust pipe body 15 and limiting the position.
