Description

Technical Field

[0001] This utility model relates to a set of small and medium-sized soil animal separation tools, belonging to the technical field of biological experimental equipment. Background Technology

[0002] Small and medium-sized soil animals (such as soil nematodes, mites, and springtails) play a vital role in soil ecosystems, especially in the transformation and fixation of soil nutrients. Accurately isolating individual organisms for classification, identification, and quantitative analysis is crucial for assessing soil health and ecological function. However, these animals are small and fragile; traditional isolation methods often rely on tweezers, which are difficult to perform, easily damage the organism's structure, affect the accuracy of subsequent identification, and prolong the experimental period.

[0003] Currently, some specialized tools have been developed for picking up soil nematodes, such as devices that use fine needles or metal wires, which to some extent ensure the accuracy of the operation and the integrity of the nematode. However, for other small and medium-sized soil animals (such as larger mites, springtails, etc., with hard body walls or round shapes), there is still a lack of specialized and efficient separation tools. Existing tools have significant limitations in terms of applicability, ease of operation, and extraction efficiency, and cannot meet diverse experimental needs.

[0004] Therefore, there is an urgent need in this field for a set of small and medium-sized soil animal separation tools that are reasonably structured, easy to operate, and widely applicable, and that can flexibly change the picking parts according to the morphological characteristics of different insects, so as to improve separation efficiency and experimental reproducibility while ensuring the integrity of the insects. Utility Model Content

[0005] The purpose of this invention is to solve the problems of damage to insects and inconvenience caused by existing tools such as tweezers when separating small and medium-sized soil animals. It overcomes the shortcomings of traditional tweezers, which are difficult to control and prone to damaging insects, and provides a specialized tool that can maintain the integrity of the insect body and improve separation efficiency. A brief overview of this invention is provided below to offer a basic understanding of certain aspects of it. It should be understood that this overview is not an exhaustive summary of the invention.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model is described below with reference to specific embodiments shown in the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and not intended to limit the scope of the present utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

[0026] The connections mentioned in this utility model are divided into fixed connections and detachable connections. Fixed connections (i.e., non-detachable connections) include, but are not limited to, conventional fixed connection methods such as folded connections, riveted connections, adhesive connections, and welded connections. Detachable connections include, but are not limited to, conventional disassembly methods such as threaded connections, snap-fit ​​connections, pin connections, and hinged connections. When a specific connection method is not explicitly defined, it is assumed that at least one existing connection method can always be found to achieve the function, and those skilled in the art can choose according to their needs. For example, a welded connection can be chosen for fixed connections, and a hinged connection can be chosen for detachable connections.

[0027] Example 1: Combination Figure 1 This embodiment describes a set of small to medium-sized soil animal separation tools, including a handle 1, a handle connector 2, a picking conversion head 3, and a picking component 4.

[0028] The handle 1 is a cylindrical rod approximately 15cm long, preferably made of lightweight metal or high-strength engineering plastic, for easy gripping and precise operation. The outer surface of the handle 1 is provided with an anti-slip component 5, which can be a rubber sleeve, knurled, or textured surface to increase friction and prevent slippage during operation.

[0029] The handle connecting part 2 is located at the end of the handle 1. In this embodiment, the connecting part 2 has an external thread structure. Correspondingly, the proximal end of the picking conversion head 3 is provided with an internal thread hole, which allows it to be detachably installed on the handle 1 through threaded engagement. This connection method is stable and reliable, and easy to replace.

[0030] The picking component 4 is fixedly installed at the distal end of the picking conversion head 3 using heat-resistant adhesive (such as hot melt adhesive). In this embodiment, the picking component 4 is made of a 0.10mm diameter nickel-chromium alloy wire, with its bottom end bent to form a bend approximately 1.5cm in length. This picking component 4 is a single nickel-chromium wire with optimized hardness and softness, moderate yet elastic, making it ideal for picking small, linear soil nematodes. During operation, the picking component 4 is immersed in a suspension containing nematodes, and the surface tension of the liquid adheres the nematodes to the surface, transferring them to a glass slide or petri dish. The entire process causes minimal damage to the nematodes.

[0031] Example 2: Combination Figure 2 This embodiment is described below. The difference between this embodiment and Embodiment 1 lies in the structure of the picking component 4.

[0032] In this embodiment, the picking component 4 is composed of two parallel nickel-chromium alloy wires with a diameter of 0.10 mm. The bottom ends of both wires are bent to form bends approximately 1.5 cm in length, and an angle is formed between the two bends, preferably ranging from 25° to 35°. This structure is particularly suitable for picking up heavier, harder, or spherical soil animals, such as mites and springtails. During operation, the double-wire picking component 4 is immersed in the suspension, and the target animal is positioned within the angle α between the two wires. A slight clamping force and the surface tension of the liquid are used to stably lift the animal from the liquid surface, thus avoiding the squeezing damage associated with traditional tweezers.

[0033] Example 3: Combination Figure 1-2 This embodiment is described below. The difference between this embodiment and the above embodiments lies in the structure of the handle connection part 2.

[0034] In this embodiment, the handle connection part 2 is a magnetic structure. Specifically, a first magnet is embedded at the end of the handle 1, and a second magnet that attracts the first magnet is embedded near the proximal end of the pick-up conversion head 3. Through magnetic attraction, the pick-up conversion head 3 and the handle 1 can be quickly connected and replaced, making operation more convenient.

[0035] Example 4: Combination Figure 3 This embodiment is described below. The difference between this embodiment and the above embodiments lies in the structure of the handle connection part 2.

[0036] In this embodiment, the handle connection 2 includes a hinge seat 21, a hinge part 22, and an adjusting bolt 23. The hinge seat 21 is fixedly installed on the end of the handle 1. One end of the hinge part 22 is fixedly connected to the picking conversion head 3, and the other end is hinged to the hinge seat 21 via a pin. The adjusting bolt 23 is used to lock the hinge part 22 in place after it has been adjusted to the required angle. This hinge structure allows the user to adjust the working angle of the picking component 4 as needed, enhancing the adaptability and flexibility of the tool in different operating scenarios.

[0037] The usage procedure of this utility model is as follows: First, according to the type of target soil animal to be separated (such as nematodes, mites, and springtails), select a picking conversion head 3 equipped with the corresponding picking component 4 (monofilament or double filament). Then, securely install the picking conversion head 3 onto the handle 1 using threads, magnets, or other methods. Finally, under a stereomicroscope, the operator holds the handle 1, immerses the picking component 4 into the sample suspension, and separates and transfers the insect using picking or clamping methods according to the characteristics of the insect.

[0038] It should be noted that in the above embodiments, as long as the technical solutions are not contradictory, they can be arranged and combined. Those skilled in the art can exhaust all possibilities based on the mathematical knowledge of permutation and combination. Therefore, this utility model will not describe the technical solutions after permutation and combination one by one, but it should be understood that the technical solutions after permutation and combination have been disclosed by this utility model.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
