[0022] One end of the cloth to be tested is placed on the inner wall of the fixed frame 51 and the other end is passed through the gap between the movable frame 53 and the pressing rod. The cloth can be initially fixed by the threaded rod 54, the connecting plate 55 and the pressing plate 57. The pressing plate 57 can be pressed tightly against the cloth with the spring 56. Then, the pressing rod on the surface of the support rod 58 can be used to press the cloth in the same way. The movable frame 53 is pulled toward the side away from the fixed frame 51 so that it slides along the slide rail 52. As the movable frame 53 slides, the pressing rod will gradually flatten the entire cloth, thereby preventing wrinkles in the cloth during the detection process and ensuring the accuracy of the detection result. The second locking hole can be used to fix the movable frame 53, and the clamping component 5 can be installed in the cabinet 1 through the hanging plate 59 and the mounting frame 4. The gas tank 62 and the flamethrower 63 in the detection component 6 can be used to perform flame detection on the fabric. The motor 65 and the lead screw 64 can drive the flamethrower 63 to rise and fall, and the electric push rod 2 and the telescopic rod 3 can drive the mounting frame 4 to move forward and backward, so as to adjust the position between the fabric and the flamethrower 63, so as to facilitate flame detection on the entire surface of the fabric. The exhaust fan 73 and the purification component 72 in the purification component 7 can prevent the exhaust gas from polluting the environment, which not only ensures people's health but also helps protect the environment.

[0023] See also Figure 1 , Figure 2 , Figure 3 and Figure 4 The utility model provides a technical solution: the clamping assembly 5 includes a fixed frame 51 movably connected to the right side of the mounting frame 4, one side of the fixed frame 51 is fixedly connected to two slide rails 52, one side of the slide rail 52 is provided with a plurality of first limiting holes, the first limiting holes are threadedly connected with limiting bolts, a moving frame 53 is slidably connected in the slide rail 52, and a second limiting hole is provided at the bottom of the moving frame 53 near the first limiting hole.

First, place one end of the cloth to be tested on the inner wall of the fixed frame 51 and pass the other end through the gap between the moving frame 53 and the pressing rod. Then rotate the threaded rod 54 at the top of the fixed frame 51. Due to the restriction of the fixed frame 51, the threaded rod 54 will drive the connecting plate 55 at its bottom to move toward the cloth until the pressing plate 57 under the connecting plate 55 contacts the top of the cloth. At this time, as the connecting plate 55 continues to move downward, the spring 56 will shrink and seek to reset, so that the pressing plate 57 can press the cloth tightly. Then, the pressing roller on the surface of the support rod 58 can press the cloth tightly by the same method. Next, the movable frame 53 is pulled toward the side away from the fixed frame 51 so that it slides along the slide rail 52. As the movable frame 53 slides, the pressing rod will gradually flatten the entire fabric, thereby preventing the fabric from wrinkling during the detection process and ensuring the accuracy of the detection result. After the pressing rod moves to the other end of the fabric, the locking bolt is rotated to pass through the first locking hole opened on one side of the slide rail 52 and the second locking hole opened on one side of the movable frame 53 in sequence, so that the movable frame 53 can be fixed in the slide rail 52.

Here, the purification component 72 is a filter box with activated carbon stored inside.

[0026] An observation window 9 is fixedly connected to the inner wall of the cabinet door 8, and a sealing ring 10 is fixedly connected to the front end of the cabinet body 1.

The movement track of the pressing plate 57 and the pressing roller can be restricted by the guide rod and the guide hole, and the anti-skid pad 11 can prevent the cloth from sliding on the inner wall of the fixing frame 51 during the flattening process.

[0028] Specific implementation method: first, place one end of the cloth to be tested on the inner wall of the fixed frame 51 and make the other end pass through the gap between the movable frame 53 and the pressing roller, then rotate the threaded rod 54 at the top of the fixed frame 51, due to the restriction of the fixed frame 51, the threaded rod 54 will drive the connecting plate 55 at its bottom end to move toward the cloth until the pressing plate 57 located under the connecting plate 55 contacts the top of the cloth, at this time, as the connecting plate 55 continues to move downward, the spring 56 will shrink and seek to reset, so that the pressing plate 57 can tightly press the cloth, and then the pressing roller on the surface of the support rod 58 can press the cloth by the same method, and then pull the movable frame 53 toward the side away from the fixed frame 51 so that it slides along the slide rail 52, and as the movable frame 53 slides, the pressing roller will gradually flatten the entire cloth, thereby preventing the cloth from wrinkling during the detection process and ensuring the accuracy of the detection result, and after the pressing roller moves to the other end of the cloth, the locking bolt is rotated to make it successively By passing through the first locking hole opened on one side of the slide rail 52 and the second locking hole opened on one side of the movable frame 53, the movable frame 53 can be fixed in the slide rail 52.
