Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for insect specimen preparation, and in particular to an auxiliary device for insect specimen preparation. Background Technology

[0002] The reproductive organs of insects are an important feature for morphological identification. In some species of Diptera and Lepidoptera, such as flies, butterflies, and moths, the reproductive organs are located at the end of the abdomen, making direct observation and complete display impossible under normal conditions, thus hindering morphological identification. In practice, the male reproductive organs (claspers) located at the end of the abdomen need to be completely extracted using the tail-pulling method for full display and morphological identification. This method requires using a dissecting microscope or stereomicroscope, employing a fine hook to penetrate deeply into the insect's abdomen from the end, applying even force outwards until the claspers and spermatheca are completely removed. Similarly, in female specimens, the ducts, bands, and copulatory sacs can be completely extracted without damaging the scales or bristles, facilitating morphological identification and specimen display. Currently, there is no specific insect specimen preparation device for this operation. In practice, staff often need to use sharp objects such as insect needles or dissecting needles. Since different insect species have different body structures, shapes, and sizes, staff need to find suitable operating devices for different insect species. Moreover, because these are not specialized instruments, errors can occur during operation, affecting work efficiency. Sharp, cutting needles or blades are required when extracting the cerci and pulling them out. In addition to the inconvenience of operation, there is also a risk of finger injuries from sharp objects. Furthermore, some insects may carry pathogens, which could pose a health threat to staff.

[0013] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] Please refer to Figures 1 to 3 This utility model provides an insect specimen preparation aid, including a pen bowl 1, a rod 4, a probe 3, a spring 10, a knob 8, and an extrusion mechanism; The pen bowl 1 is a hollow column structure with an opening at the top. The inner wall of the pen bowl 1 is provided with a plurality of protrusions 9 at equal intervals along its circumference. The protrusions 9 are provided with mounting holes. The bottom of the pen bowl 1 is provided with a through hole 2 corresponding to the mounting hole. The rod 4 is installed in the mounting hole. The rod body of the rod 4 is provided with a limit ring 5. The probe 3 is installed at the bottom of the rod 4. The probe 3 installed at the bottom of different rods 4 are also different. The spring 10 is sleeved on the rod 4, one end of the spring 10 is connected to the limiting ring 5, and the other end of the spring 10 is connected to the protrusion 9; The knob 8 is rotatably mounted on the top of the pen holder 1; The extrusion mechanism is located inside the knob 8 and is used to extrude one of the rods 4 from the pen bowl 1; In use, the rods 4 retract into the bowl 1 under the action of the spring 10, and the top end of the rod 4 rests against the bottom of the knob 8. Rotating the knob 8 moves the extrusion mechanism inside the knob 8 above the corresponding rod 4, and the extrusion mechanism pushes the corresponding rod 4 downward, so that the probe 3 at the bottom of the rod 4 protrudes outside the bowl 1, which is convenient for making insect specimens. The knob 8 can switch between different types of probes 3, which greatly improves the efficiency of insect specimen making and improves the safety of the operation process.
