[0026] The support telescopic rod mechanism 4 includes a telescopic rod 401 located inside the main rod 1. The telescopic rod 401 and the main rod 1 are slidably connected. The telescopic rod 401 is provided with a plurality of positioning holes 402. The bottom of the telescopic rod 401 is provided with three rotating seats 403, which are rotatably connected to the support insert rod 404.

[0027] Specifically, by controlling the length of the telescopic rod 401 extending beyond the main rod 1, when adjusted to the specified extension length, the relative position of the telescopic rod 401 and the main rod 1 is limited by the positioning bolt 5, and the insertion into the ground can be achieved by the support rod 404.

[0028] The deflection seat mechanism 6 includes a deflection seat 601 fixed on the main rod 1. The deflection seat 601 is rotatably connected to two deflection shafts 602.

[0031] Specifically, turning on the second motor 802 can drive the rotating shaft 803 to rotate. The rotation of the rotating shaft 803 will drive the arc-shaped shell 804 to rotate. The rotation of the arc-shaped shell 804 will drive the cutting blade 809 to revolve around the rotating shaft 803. Under the action of centripetal force, the cutting blade 809 and the rotating ring 808 can rotate, so that the cutting blade 809 can unfold. Under the action of the cutting blade 809, the obstructing branches can be cut.

[0032] The shrink belt mechanism 9 includes a housing 901 fixed to the mounting housing 7. A first rotating shaft 902 is provided inside the housing 901. The first rotating shaft 902 is fixedly connected to a shrink belt pulley 903 and a worm gear 905. A shrink belt 904 is provided on the shrink belt pulley 903. Both ends of the shrink belt 904 are connected to the shrink belt pulley 903. The shrink belt 904 passes through the housing 901 and is slidably connected to the housing 901. The middle part of the shrink belt 904 is fixedly connected to the sampling bag 11. The worm gear 905 meshes with a worm wheel 906. The worm wheel 906 is fixedly connected to a second rotating shaft 907. The second rotating shaft 907 is rotatably connected to the housing 901. The second rotating shaft 907 is fixedly connected to a first bevel gear 908. The first bevel gear 908 meshes with a second bevel gear 909. The second bevel gear 909 is fixedly connected to a third rotating shaft 910. The third rotating shaft 910 is fixedly connected to a first magnetic circular plate 911. The sampling bag 11 is symmetrically connected to the shrink tape 904 and fixedly connected to the housing 901. The drive adjustment mechanism 10 includes a third motor 1001 disposed in the mounting housing 7. The output shaft of the third motor 1001 is fixedly connected to a threaded rod 1002. The threaded rod 1002 is rotatably connected to the mounting housing 7. The threaded rod 1002 is threadedly connected to an adjusting block 1003. The adjusting block 1003 is slidably connected to the mounting housing 7. A fourth motor 1004 is disposed on the adjusting block 1003. The output shaft of the fourth motor 1004 is fixedly connected to a second magnetic circular plate 1005. The second magnetic circular plate 1005 and the first magnetic circular plate 911 attract each other.

[0033] Specifically, when the third motor 1001 is turned on, the output shaft of the third motor 1001 rotates, which drives the threaded rod 1002 to rotate. The rotation of the threaded rod 1002 drives the adjusting block 1003 to move along the mounting shell 7, thereby adjusting the position of the second magnetic circular plate 1005. When it is necessary to retract or expand the shrinkage belt 904 at a specified position, the fourth motor 1004 is turned on. The rotation of the output shaft of the fourth motor 1004 drives the second magnetic circular plate 1005 to rotate. The rotation of the second magnetic circular plate 1005 drives the first magnetic circular plate 911 at a specified position. The rotation of the first magnetic circular plate 911 drives the third rotating shaft 910 to rotate, which in turn drives the second bevel gear 909 to rotate. The rotation of the second bevel gear 909 drives the first bevel gear 908 to rotate, which in turn drives the second rotating shaft 907. The rotation of the second rotating shaft 907 drives the worm gear 906 to rotate, which in turn drives the worm 905 to rotate, which in turn drives the shrink pulley 903 to rotate. This controls the extension length of the shrink belt 904, thereby adjusting the size of the sampling bag 11 at the designated position, so as to adaptively adjust the overall size and shape of the sampling bag 11.

[0034] Example 2, see below. Figures 1-6 In this embodiment of the invention, the sampling bag 11 is made of Teflon material.

[0035] Example 3, see below. Figures 1-6 In this embodiment of the invention, the sampling bag 11 is provided with an air filter and an adsorption tube, so that the sampled gas is collected by the gas collector 12 and enters the adsorption tube through the air filter.

[0036] In addition, a photosynthetically active radiation sensor is provided inside the sampling bag 11 to detect the photosynthetically active radiation inside the sampling bag 11.

[0037] Specifically, the gas collector 12 is equipped with an air inlet and an air outlet. The air outlet of the gas collector 12 can be connected to an atmospheric sampler and a Teflon adsorption tube.

[0038] In the implementation of this invention, first, hold the handle 2 and adjust the sampling bag 11 to the specified height. Then, depending on the angle of the branch to be sampled, adjust the state of the deflection seat mechanism 6, and then adjust the angle of the mounting shell 7. Then, put the branch into the sampling bag 11. If other branches obstruct the sampling, the obstructing branches are cut by the cutting blade mechanism 8. Then, according to the size and shape of the branch, adjust the drive adjustment mechanism 10, and then drive the shrink belt mechanism 9 at different positions to adjust the size and shape of the sampling bag 11. The gas collector 12 can collect the gas generated by the branch. The temperature and humidity sensor 13 can detect the temperature and humidity of the air inside the sampling bag 11. The display control panel 3 can display various data and control the motor. During the collection process, the main pole 1 can be connected to the ground by the support telescopic rod mechanism 4.

[0039] This invention enables the main rod 1 to be supported and connected to the ground during sampling by setting up a support telescopic rod mechanism 4. The positioning bolt 5 can limit the relative position of the support telescopic rod mechanism 4 and the main rod 1. The deflection seat mechanism 6 can adjust the deflection angle of the mounting shell 7, thereby adjusting the deflection angle of the sampling bag 11 to adapt to tree branch sampling at different angles. The cutting blade mechanism 8 can cut branches that obstruct sampling. The drive adjustment mechanism 10 can drive the shrinkage belt mechanism 9 at a specified position. The shrinkage belt mechanism 9 can adjust the size and shape of the sampling bag 11, thereby improving the efficiency of tree species BVOCs sampling.

[0040] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
