[0020] Embodiment: A pine wood nematode trapping device, as Figures 1 - 3 shown, includes a trapping cylinder 1, a medicine loading cylinder 2, a guiding plate 4 and a fixing mechanism. An inlet and an operation port are provided on the trapping cylinder 1, and the position of the inlet corresponds to that of the operation port. The lower inner side of the trapping cylinder 1 is connected with a medicine loading cylinder 2, and a guiding plate 4 is connected to the trapping cylinder 1. The guiding plate 4 is located above the inlet. There are two fixing mechanisms, both of which are arranged on the trapping cylinder 1, so as to be able to fix the trapping cylinder 1 more stably on a pine tree. The fixing mechanism includes a fixing ring 5, a fixing belt 6, a connecting block 7, a clamping post 8 and a fixing nail 9. A fixing ring 5 is connected to the trapping cylinder 1, a fixing belt 6 is connected to the fixing ring 5. At least six fixing nails 9 are provided on the inner side surface of the fixing ring 5. A plurality of holes are provided on the fixing belt 6. The side of the fixing ring 5 that is not connected to the fixing belt 6 is rotatably connected with a connecting block 7, and a clamping post 8 is rotatably connected to the connecting block 7. The clamping posts 8 can all fit with the holes on the fixing belt 6, so that the device can adapt to pine trees with different circumferences, effectively improving the adaptability of the device.

[0021] As Figure 1 Figure 2, Figure 4 and Figure 5 As shown, it further includes a partition frame 3, a rotating shaft 10, a cover plate 11, a connecting ring 12, a handlebar 13, a push rod 131, a brush 14, a scroll spring 15 and an elastic member 16. A partition frame 3 is slidably connected inside the medicine loading cylinder 2, so that the device can separate the corpses of pine wood nematodes from the attracting agent; a rotating shaft 10 is rotatably connected to the trapping cylinder 1, a cover plate 11 is connected to the rotating shaft 10, and the cover plate 11 fits with the operation port. While the cover plate can prevent the pine wood nematodes from escaping, it also facilitates refilling the medicine for the device; a connecting ring 12 is rotatably connected to the trapping cylinder 1, a handlebar 13 is slidably connected to the connecting ring 12, a push rod 131 is connected to the upper part of the handlebar 13, the push rod 131 is located between the handlebar 13 and the upper side surface of the trapping cylinder 1, a brush 14 is rotatably connected to the lower end of the handlebar 13, a scroll spring 15 is connected to the inner side of the upper part of the trapping cylinder 1, the end of the scroll spring 15 not connected to the trapping cylinder 1 is connected to the handlebar 13, and an elastic member 16 is connected between the handlebar 13 and the trapping cylinder 1 through a spring seat. Press down and rotate the handlebar 13, so that the handlebar 13 can drive the brush 14 to coat the anti-escape powder on the inner wall below the inlet of the medicine loading cylinder 2, thereby preventing the pine wood nematodes from escaping.

[0022] When using this device, first make the fixing nail 9 closely adhere to the outer bark of the pine tree that needs to be de-insectized, and then strike the fixing ring 5 to embed the fixing nail 9 connected to the inner side of the fixing ring 5 into the pine tree, so that the device is not easy to slip off the pine tree; then wind the fixing belt 6 around the pine tree, and insert the end of the fixing belt 6 into the connecting block 7, stretch the fixing belt 6 to make it closely adhere to the outer bark of the pine tree. At this time, fit the clamping post 8 with the similar hole groove on the fixing belt 6, and make the clamping post 8 pass through the hole groove and contact the left part of the connecting block 7, so as to fix the device on the pine tree. At this time, the rear side of the guide plate 4 fits with the pine tree, so that when the subsequent pine wood nematodes are attracted by the attracting agent, they can enter the trapping cylinder 1 through the guide plate 4. Repeat the above steps and use another fixing mechanism to fix the device more firmly on the pine tree. This device is equipped with fasteners without the need for additional equipment, and this device can easily and quickly fix itself firmly on the pine tree. Pull the cover plate 11 to the right, and the cover plate 11 will rotate upward with the rotating shaft 10. Then move it upward to take out the partition frame 3 to expose the feeding port of the medicine loading cylinder 2. Pour the attracting agent into the medicine loading cylinder 2, then reset the partition frame 3 in sequence, and then press down the turning handle 13. The turning handle 13 will slide down on the connecting ring 12, and the elastic member 16 will be compressed. When the lower end of the ejector rod 131 contacts the upper side of the trapping cylinder 1, it indicates that the brush 14 is located below the inlet of the medicine loading cylinder 2 at this time. Make the container filled with anti-escape powder contact the brush 14 through the operation port, and make the brush 14 fully covered with anti-escape powder. After completion, reset the cover plate 11. At this time, rotate the turning handle 13 again, and the turning handle 13 will coat the inner wall below the inlet of the medicine loading cylinder 2 with anti-escape powder with the brush 14, so that the subsequent pine wood nematodes entering the trapping cylinder 1 cannot escape, thus effectively removing the pine wood nematodes on the pine tree. When rotating the turning handle 13, the scroll spring 15 will be wound up. After the anti-escape powder is coated, release the turning handle 13, and the scroll spring 15 will drive the turning handle 13 to rotate and reset, and the elastic member 16 will drive the turning handle 13 to move upward and reset. Subsequently, open the cover plate 11 to take out the partition frame 3, and clean the corpses of the pine wood nematodes in the partition frame 3, and then replenish the attracting agent in the medicine loading cylinder 2. After completion, reset the partition frame 3 and the cover plate 11, so that this device can separate the corpses of the pine wood nematodes from the attracting agent, effectively preventing the waste of the attracting agent.

[0023] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structure or equivalent process transformation made by using the content of the specification of the present invention, or directly or indirectly applied in other related technical fields, shall be included in the patent protection scope of the present invention by the same token.
