[0022] Specifically, manually move the insertion rod 12 away from the slider 4, at this time the second spring 14 is stretched, and then manually move the slider 4 toward the smaller end of the barrel 1 to a suitable position, driving the circular plate 2 to move synchronously in the same direction. At this time, the first spring 7 is stretched, driving the insect pin 10 to move synchronously in the same direction and completely leak out of the barrel 1, then release the insertion rod 12, and when the second spring 14 recovers its deformation, pull the lower insertion rod 12 back to its original position and insert the end into the socket 15. At this time, the position of the slider 4 is fixed, that is, the position of the insect pin 10 is fixed. When dissection is required, first use the insect pin 10 to remove the insect pin. The tip of the needle 10 gently incises a small opening above the parasitized egg, then slides the tip of the insect needle 10 left and right to peel off the host egg shell. The tip of the insect needle 10 is then dipped in distilled water to rinse the tip of the insect needle 10. After rinsing, the tip of the insect needle 10 can be gently touched to the larva or pupa of the black egg wasp of the Noctuidae moth. The insect body will stick to the tip of the insect needle 10, and the insect body is quickly immersed in liquid nitrogen for preservation. After the dissection and collection are completed, the insertion rod 12 is moved outward, and the first spring 7 recovers its deformation, pulling the lower circular plate 2 to reset the insect needle 10 and store it in the gun barrel 1. The purpose of this design is to allow the insect needle 10 to be stored and removed from the gun barrel 1, protecting the insect needle 10 from damage and preventing workers from being accidentally injured by the insect needle 10.
[0023] Further, such as Figure 1-3 As shown, the following preferred technical solutions are provided:
[0024] A connecting block 3 is fastened between the outer side of the circular plate 2 and the end of the slider 4. A first rectangular groove 5 communicating with the interior is provided on the outer side of the barrel 1. A second rectangular groove 6 is provided on the outer side of the first rectangular groove 5. The outer side of the circular plate 2 is slidably connected to the inner side of the barrel 1, the connecting block 3 is slidably connected to the inner side of the first rectangular groove 5, and the slider 4 is slidably connected to the inner side of the second rectangular groove 6. The purpose of this design is to ensure that the slider 4 drives the circular plate 2 to move back and forth in a straight line along the axis direction of the barrel 1.
[0025] Further, such as Figure 2 and Figure 3 As shown, the following preferred technical solutions are provided:
[0026] A T-shaped plug 9 is fixed to the end of the insect pin 10, and the inner side of the T-shaped plug 9 is threadedly connected to the inner side of the bottom end of the sleeve 8. The upper end of the sleeve 8 is fixed to the middle part of the bottom end of the circular plate 2. The purpose of this design is that the circular plate 2 drives the insect pin 10 at the lower end of the sleeve 8 to move synchronously, and it is also convenient for disassembly and assembly of the insect pin 10 for replacement.
[0027] Further, such as Figure 2 As shown, the following preferred technical solutions are provided:
[0028] The first spring 7 is tightly connected between the top surface of the barrel 1 and the upper end of the circular plate 2. The first spring 7 drives the insect pin 10 to be completely retracted into the barrel 1. When the circular plate 2 is manually moved to a limited position, it drives the insect pin 10 to completely leak out. The purpose of this design is to ensure the rationality of the structure.
[0029] Further, such as Figure 1 and Figure 4 As shown, the following preferred technical solutions are provided:
[0030] The insertion rod 12 is slidably connected to the support plate 11, and a handle 13 is fixed to the end of the insertion rod 12. The second spring 14 is tightly connected between the side of the handle 13 and the side of the support plate 11. The second spring 14 drives the insertion rod 12 away from the handle 13 and engages with the inner side of the hole 15. The purpose of this design is to fix the position of the slider 4 by engaging the insertion rod 12 with the hole 15.
[0031] Further, such as Figure 1 As shown, the following preferred technical solutions are provided:
[0032] An auxiliary plate 16 is fixedly provided on the upper end of the outer side of the gun barrel 1. The purpose of this design is to make it easier to hold the gun barrel 1 tightly by clamping the auxiliary plate 16 when holding the gun barrel 1.
[0033] To sum up: manually move the insertion rod 12 away from the slider 4, at this time the second spring 14 is stretched, and then manually move the slider 4 toward the smaller end of the barrel 1 to a suitable position, driving the circular plate 2 to move synchronously in the same direction. At this time, the first spring 7 is stretched, driving the insect pin 10 to move synchronously in the same direction and completely leak out of the barrel 1, then release the insertion rod 12, and when the second spring 14 recovers its deformation, pull the lower insertion rod 12 back to its original position and insert the end into the socket 15. At this time, the position of the slider 4 is fixed, that is, the position of the insect pin 10 is fixed. When dissection is required, first use the insect pin 10 to remove the insect pin. The tip of the insect needle 10 gently incises a small opening above the parasitized egg, then slides the needle tip 10 left and right to peel off the host egg shell. The tip of the insect needle 10 is then dipped in distilled water to rinse the tip of the insect needle 10. After rinsing, the insect needle 10 tip can be gently touched to the larva or pupa of the black egg wasp of the Noctuidae moth. The insect body will stick to the needle tip of the insect needle 10, and the insect body is quickly immersed in liquid nitrogen for preservation. After the dissection and collection are completed, the insertion rod 12 is moved outward, and the first spring 7 recovers its deformation, pulling the lower circular plate 2 to reset the insect needle 10 and store it in the gun barrel 1. The purpose of this design is to allow the insect needle 10 to be stored and removed from the gun barrel 1, protecting the insect needle 10 from damage and preventing workers from being accidentally injured by the insect needle 10.
