[0024] In the structure, when the placing rod 11 and the tooth-shaped block 13 are placed to the inner wall of the placing groove 10 and the tooth-shaped groove 12, the placing rod 11 is limited by the engagement of the tooth-shaped block 13 and the tooth-shaped groove 12, so that the placing rod 11 cannot shake left and right, and then the placing rod 11 and the tooth-shaped block 13 are fixed by the threaded connection of the bolt 14 and the inner wall of the threaded groove 15, so that the placing rod 11 cannot be pulled out from the inner wall of the placing groove 10, thereby realizing the connection and fixation of the fixed block 3 and the filter plate 4.

[0025] In a preferred embodiment: the outer wall of the filter plate 4 is fixedly provided with the placing block 6, the bottom of the placing block 6 is fixedly provided with the clamping block 7, the outer wall of the limiting block 8 is provided with the clamping groove 9, and the outer wall of the sampling probe body 1 is provided with the clamping groove 5.

[0026] In the structure, the filter plate 4 is used to filter the impurities in the gas sucked by the equipment, so as to avoid the blockage of the sampling probe body 1 during long-term use and the problem that the filtering effect of the filter plate 4 decreases over time. The worker needs to rotate the bolt 14 to rotate it out of the threaded groove 15 on the outer wall of the placing rod 11 and the filter plate 4. When the bolt 14 is removed from the inner wall of the threaded groove 15, the limiting of the placing rod 11 is released, so that the worker can pull out the placing rod 11 and the tooth-shaped block 13 from the inner wall of the tooth-shaped groove 12 and the placing groove 10. At the same time, during the process of taking out the placing rod 11, the limiting between the fixed block 3 and the filter plate 4 is released, so that the filter plate 4 can shake freely. Then, the worker needs to hold the filter plate 4 and move the placing block 6, which will move the clamping block 7 out of the inner wall of the clamping groove 9, thereby releasing the final limitation of the filter plate 4, realizing the replacement of the filter plate 4, and achieving the purpose of preventing the blockage of the sampling probe body 1.

[0027] In a preferred embodiment: the installation assembly 2 comprises a connecting block 201, one end of the connecting block 201 is fixedly provided with a spring 202, the other end of the spring 202 is fixedly provided with a pressure receiving block 203, the top of the connecting block 201 is fixedly provided with a fixed plate 204, the inner wall of the fixed plate 204 is rotatably connected with a rotating rod 205, the outer wall of the rotating rod 205 is fixedly provided with a clamping block 206, and the inner wall of the clamping block 206 is rotatably connected with a connecting rod 207.

[0028] In the structure, during the installation of the sampling probe body 1, the worker applies pressure to the pressure block 203, so that the pressure block 203 is pressed and then applies pressure to the spring 202 and the connecting rod 207. After being pressed, the connecting rod 207 rotates on the inner wall of the clamping block 206 and applies pressure to the clamping block 206 at the same time, thereby driving the clamping block 206 to rotate on the inner wall of the fixed plate 204. With the rotation of the clamping block 206, it moves along the inner wall of the clamping groove 5 formed on the outer wall of the sampling probe body 1. When the clamping block 206 moves to the inner wall of the clamping groove 5 and is properly placed, the installation of the sampling probe body 1 is completed. In addition, the elastic potential energy of the spring 202 can further enhance the stability between the clamping block 206 and the sampling probe body 1, thereby realizing the rapid installation of the sampling probe body 1.

[0029] In a preferred embodiment: the connecting rod 207 is fixedly assembled with the outer wall of the pressure block 203, and the clamping block 206 is matched with the inner wall of the clamping groove 5.

[0030] In the structure, the clamping block 206 and the pressure block 203 are used to limit the connecting rod 207, so that the pressure block 203 does not rotate when placed. The clamping block 206 and the clamping groove 5 are used to connect the connecting block 201 and the sampling probe body 1.

[0031] In a preferred embodiment: the placement rod 11 is engaged with the inner wall of the tooth-shaped groove 12 through the tooth-shaped block 13, and the inner wall of the placement groove 10 is provided with a threaded groove 15.

[0032] In the structure, the tooth-shaped groove 12 and the tooth-shaped block 13 are used to limit the placement rod 11, so that the placement rod 11 does not rotate when placed in the inner wall of the placement groove 10. When the bolt 14 is rotated to the inner wall of the threaded groove 15, the fixed block 3 and the filter plate 4 are connected and fixed.

[0033] In a preferred embodiment: the clamping block 7 is clamped with the inner wall of the clamping groove 9, and the filter plate 4 is matched with the slot of the sampling probe body 1.

[0034] In the structure, the clamping block 7 is clamped with the inner wall of the clamping groove 9, so as to fix the filter plate 4, so that the filter plate 4 is more stable when placed and does not rotate. When the filter plate 4 is placed on the slot of the sampling probe body 1, the slot is protected.

[0035] Working principle: by using filter plate 4 to remove the gas impurities sucked by the equipment, the blocking phenomenon can be prevented from occurring in long-term use, however, the filtering efficiency of filter plate 4 will gradually decrease over time, in order to replace filter plate 4, the worker needs to rotate bolt 14, so that it is separated from the outer wall of placing rod 11 and filter plate 4 Threaded groove 15, when bolt 14 moves out of the inner wall of threaded groove 15, the restriction on placing rod 11 will be removed, allowing the worker to pull out placing rod 11 and toothed block 13 from the inner wall of toothed groove 12 and placing groove 10, during the removal of placing rod 11, the limit between fixing block 3 and filter plate 4 is also cancelled, allowing filter plate 4 to swing freely, then the worker lifts filter plate 4 with force, driving placing block 6 to move, and placing block 6 will move the clamping block 7 out of the inner wall of the clamping groove 9 during the movement, thereby removing the last restriction on the filter plate 4, so that the filter plate 4 can be replaced, thereby preventing the sampling probe body 1 from being blocked, during the installation of the sampling probe body 1, the worker applies pressure to the pressure block 203, so that it exerts pressure on the spring 202 and the connecting rod 207, the connecting rod 207 will rotate in the inner wall of the clamping block 206 after being subjected to pressure, and will exert pressure on the clamping block 206 during rotation, prompting the clamping block 206 to drive the rotating rod 205 to rotate in the inner wall of the fixed plate 204, when the clamping block 206 moves to the inner wall of the clamping groove 5 and is placed in place, the installation of the sampling probe body 1 is completed, in addition, the elastic potential energy of the spring 202 ensures the stability between the clamping block 206 and the sampling probe body 1, thereby realizing the quick installation of the sampling probe body 1.
