[0022] The outer wall of the connecting head 5 is bonded with a movable plate 501, the hole of the movable plate 501 is bonded with a first spring 503, the first limit block 502 is glued above the first spring 503, the interior of the movable plate 501 is provided with a slide groove 504, the interior of the movable plate 501 is bonded with a movable cylinder 511, the outer wall of the movable cylinder 511 is provided with a limit hole 505, the interior of the movable cylinder 511 is bonded with an outer shell 510, the outer wall of the outer shell 510 is bonded with a sealing ring 506, the interior of the outer shell 510 is bonded with an inner liner 509, the outer wall of the inner liner 509 is glued with a second spring 508, and a second limit block 507 is glued to one side of the second spring 508.

[0023] In this embodiment, Figure 1 , Figure 2 and Figure 4As shown, a lower joint 606 is welded at the bottom of the fixed disk 6, a sliding sleeve 605 is welded at the top of the fixed disk 6, a pressing block 602 is attached to the inside of the sliding sleeve 605, an insert rod 604 is welded to the outer wall of the pressing block 602, a third spring 603 is glued to the top of the pressing block 602, an upper joint 601 is glued to the top of the third spring 603, a fixing frame 610 is installed on one side of the fixed disk 6 by screws, a threaded rod 608 is threadedly connected to the inside of the fixing frame 610, a pressing plate 609 is welded at the bottom of the threaded rod 608, a rotating disk 607 is welded at the top of the threaded rod 608, a lower joint 606 is welded at the bottom of the fixed disk 6, and the interior of the sliding sleeve 605 is provided with a plurality of V-shaped slideways, and the pressing block 602 is connected to the third spring 603 by means of a screw. The spring 603 forms an elastic structure; if the device cannot be rotated in a fixed direction, it may be limited to sampling in a fixed direction, which may result in the inability to cover all areas that require sampling. By pressing the detector 1 downward, the detector 1 presses the upper joint 601 downward, and the upper joint 601 moves the pressing block 602 downward through the pressure of the third spring 603. Since the surface of the pressing block 602 is provided with an insertion rod 604, the insertion rod 604 can move along the hole of the sliding sleeve 605, so that the pressing block 602 can rotate and self-lock the upper joint 601 by pressing, so that the detector 1 can adjust the direction of sampling, which helps to capture pollutants in different positions or directions in the air, thereby obtaining more representative sampling data.

[0024] In this embodiment, Figure 4 As shown, the pressing plate 609 forms a rotating structure through the threaded rod 608, and the external structural dimensions of the threaded rod 608 are consistent with the internal structural dimensions of the fixing frame 610; generally, the air sampling equipment is fixed by a tripod and cannot be fixed by itself. The sampling equipment that relies on the tripod for fixing can usually only sample at a fixed position and cannot be flexibly moved to other positions, which may limit the scope of application of the sampling equipment, especially for applications that require sampling at different positions or heights, resulting in inconvenience in sampling. By rotating the turntable 607, the threaded rod 608 connected to the turntable 607 is connected to the thread of the pressing plate 609, and the pressing plate 609 can be fixed on other objects, which is convenient for carrying for sampling. There is no need to carry a tripod separately, and it can be fixed on existing objects on site, increasing flexibility of use.

[0025] In this embodiment, Figure 3As shown, the second limit block 507 forms an elastic structure through the second spring 508, and the external structural size of the second limit block 507 is consistent with the holes of the limit hole 505 and the slide groove 504; the air sampling tube 2 is generally assembled and connected through multiple pipes, and each connection point is a potential leakage point. If the connection is not firm or the seal is poor, it may cause gas leakage in the air sampling tube 2 system, affecting the accuracy of the sampling result. It is generally connected manually and pushed in horizontally, and needs to be constantly adjusted to avoid leakage and affect the sampling time. Now, by pressing the second limit block 507, the second limit block 507 is elastically moved downward by the second spring 508, and the shell 510 is pushed into the inside of the moving cylinder 511, so that the second limit block 507 is respectively inserted into the inside of the limit hole 505 and the slide groove 504, and the surface of the shell 510 is provided with a sealing ring 506 for sealing, which can be quickly assembled to reduce frequent position adjustments, and the sealing ring 506 is used to seal to avoid leakage, which is convenient for installation and quick disassembly.

[0026] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the first limit block 502 forms an elastic structure through the first spring 503, and the external structural size of the first limit block 502 is consistent with the internal structural size of the hole of the movable plate 501; connecting multiple air sampling tubes 2 will increase the complexity of the system, making maintenance and cleaning more difficult, and easily accumulating pollutants or clogging. The connector 5 is moved horizontally, and the first limit block 502 provided on the connector 5 is elastically moved downward by the first spring 503, and the first limit block 502 is stuck in the movable plate 501. The first limit block 502 pops up and can be stably fixed to avoid movement, and the sampling tube 2 can be easily disassembled for easy cleaning and maintenance. This is crucial to ensure that the sampling tube 2 remains clean and avoids contamination and cross-contamination.

[0027] In this embodiment, Figure 3 As shown, the internal structural dimensions of the movable plate 501 are consistent with the external structural dimensions of the movable cylinder 511, and the internal structural dimensions of the movable cylinder 511 are consistent with the external structural dimensions of the outer shell 510; the movable plate 501 and the movable cylinder 511 are detachable, and the movable cylinder 511 and the outer shell 510 are detachable, and the detached sampling tube 2 is small in size, convenient for storage and transportation, does not take up too much space, and is easy to carry.

[0028] The use method and advantages of the utility model: When the portable sampling device is used, the working process is as follows:

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, first, the connecting tube 4 and the sampling tube 2 are connected through the connecting head 5, the second limit block 507 moves the second spring 508 horizontally to one side, and the housing 510 moves horizontally to one side into the interior of the moving cylinder 511. The second spring 508 causes the second limit block 507 to enter the limiting hole 505 and the slide groove 504 in sequence through inertia, and the moving plate 501 moves to one side, causing the first limit block 502 to enter the hole of the moving plate 501 through inertia, thereby respectively fixing the connecting tube 4 and the sampling tube 2, which is convenient for quick fixing and disassembly. The upper joint 601 is The thread is consistent with the thread of the detector 1, and the thread of the lower joint 606 can be fixed on the tripod. The turntable 607 drives the threaded rod 608 and the pressing block 602 to rotate clockwise in turn. The fixed frame 610 is consistent with the thread of the threaded rod 608, so that the pressing block 602 fixes the object to support the detector 1 and fixes it into the tripod. There are two fixing methods. The detector 1 drives the pressing block 602, the third spring 603 and the insertion rod 604 to move downward in turn, so that the insertion rod 604 moves along the hole of the sliding sleeve 605, thereby achieving the rotation and self-locking of the detector 1.
