[0002] Microbial virulence detection experiments are widely used in the screening of high virulence strains of microorganisms, the development of microbial vaccines, drug research, biological engineering and other medical related fields. Conventional microbial virulence detection experiments usually select mice or galleria mellonella larvae to make animal infection models. Compared with mice, galleria mellonella larvae are the preferred choice for researchers to make models for microbial virulence experiments because they are economical, do not need to be fed, and are convenient to store. Due to the small size and high activity of galleria mellonella larvae, the larvae need to be fixed head-to-tail before the experiment to prevent them from moving.

[0003] When performing galleria mellonella larvae infection experiments, a very small injection amount is usually used, so a microsyringe is used for injection. When using a microsyringe, one hand holds the needle and the other hand supports the needle to ensure the accuracy of needle insertion. Therefore, in the past, multiple researchers had to work together to complete the galleria mellonella larvae infection experiment, making the experimental operation complex and greatly increasing the experimental labor cost.

[0028] To provide a more detailed understanding of the features and technical content of the embodiments of this disclosure, the implementation of the embodiments of this disclosure will be described in detail below with reference to the accompanying drawings. The accompanying drawings are for illustrative purposes only and are not intended to limit the embodiments of this disclosure. In the following technical description, for ease of explanation, several details are used to provide a full understanding of the disclosed embodiments. However, one or more embodiments may still be implemented without these details. In other cases, well-known structures and devices may be simplified in their depiction to simplify the drawings.

[0029] A device for securing experimental moths (Pyralidae) includes a placement mechanism 1 and a fixing mechanism 2. The fixing mechanism 2 is located on top of the placement mechanism 1. The fixing mechanism 2, in conjunction with the placement mechanism 1, secures the pyralidae insects, facilitating experimental operations. The placement mechanism 1 mainly consists of a base plate 11, rails 13, and fixing rods 14. The base plate 11 has a square structure with legs 18 at each of the four corners for support. A square platform 12 is located on the top side of the base plate 11, and rails 13 are provided on both sides of the platform 12. The bottom sides of the rails 13 are fixedly connected to the base plate 11. A fixed rod 14 is provided between the two rails 13. The two ends of the fixed rod 14 are respectively fastened to the top side of the corresponding rail 13. The fixed rod 14 can slide along the rail 13, and the fastening between the fixed rod 14 and the rail 13 has a certain damping to ensure that the fixed rod 14 will not slide arbitrarily. The fixed rod 14 can only be slid by the operator applying external force. A limit plate 15 is fixedly provided at one end of the platform 12. The two ends of the limit plate 15 are respectively fixedly connected to the corresponding rail 13. By fixing the two rails 13 with the limit plate 15, the stability of the distance between the rails 13 can be ensured, and the range of movement of the fixed rod 14 can be limited to prevent the fixed rod 14 from detaching from the two rails 13.

[0030] The bottom side of the fixing rod 14 contacts the top side of the platform 12 and has a first groove 141 on one side. The top side of the platform 12 is provided with a fixing mechanism 2, which mainly consists of a movable rod 21 and a drive screw 25. Both ends of the movable rod 21 have fastening grooves 22 on their bottom sides. The fastening grooves 22 are slidably fastened to the two rail rods 13 respectively. The width of the fastening grooves 22 is adapted to the width of the rail rods 13. A limiting wheel 23 is rotatably provided inside the fastening grooves 22. The rail rods 13 have rail grooves 131 at the positions corresponding to the limiting wheels 23. The limiting wheels 23 are inserted into the rail grooves 131. Inside, the cooperation between the limiting wheel 23 and the rail groove 131 ensures the stability of the movable rod 21's trajectory and the smoothness of its movement along the rail 13, increasing ease of operation. Under the action of the locking groove 22, the movable rod 21 can move back and forth along the rail 13. A second groove 24 is formed on the inner side of the movable rod 21 corresponding to the position of the first groove 141. The first groove 141 and the second groove 24 correspond to each other. The space occupied by the first groove 141 and the second groove 24 is mainly used to provide space for the tweezers to move when gripping the moth. During the experiment, the moth is fixed between the movable rod 21 and the fixed rod 14. The movable rod 21 and the fixed rod 14, together with two rails 13, can be spliced ​​into an independent space. The moth used in the experiment can be placed in this space for constraint and fixation. A drive screw 25 is rotatably connected to the outside of the movable rod 21. The drive screw 25 is threaded with a positioning block 17, which is fixed to one side of the base plate 11. By rotating the drive screw 25 in conjunction with the positioning block 17, the experimenter can push and pull the movable rod 21, thereby allowing the movable rod 21 and the fixed rod 14 to approach or move away from each other. During the approach process, the activity range of the moth is gradually limited, eventually leading to its complete fixation. This allows for single-person operation, eliminating the need for multiple personnel and saving manpower. Flexible films 4 are fixedly attached to the inner sides of both the movable rod 21 and the fixed rod 14. When the moth is restricted and fixed, as the movable rod 21 moves and the space shrinks, the moth will inevitably come into contact with the movable rod 21 and the fixed rod 14. The flexible films 4 prevent rigidity from causing damage to the moth during restriction, avoiding unnecessary impact on the experiment.

[0031] The drive screw 25 is equipped with an operating knob 26 at its end, allowing the operator to easily adjust the position of the movable rod 21 by rotating the knob with one hand. Both ends of the movable rod 21 are equipped with fastening torsion bars 27. These torsion bars 27 are threaded through the ends of the movable rod 21 and extend into the inner side of the retaining groove 22. After the movable rod 21 is moved to the appropriate position by the drive screw 25, the operator can tighten the torsion bars 27 to fix the movable rod 21 to the rail 13, thereby ensuring the position of the movable rod 21 is fixed and increasing the stability of the moth fixation. The top side of one end of the fixed rod 14 is fixedly connected to the bottom end of the hinge column 142. A top cap 143 is provided at the top of the hinge column 142. An auxiliary plate 3 is provided between the top cap 143 and the fixed rod 14, and is rotatably sleeved with the hinge column 142. The auxiliary plate 3 includes a plate body 31, and a fixed hole 34 is provided at the end of the plate body 31. The auxiliary plate 3 rotatably sleeves the hinge column 142 through the fixed hole 34. A pressure spring 16 is sleeved on the outside of the hinge column 142. The top end of the pressure spring 16 abuts against the bottom side of the top cap 143, and the bottom end abuts against the top side of the end of the auxiliary plate 3. The pressure spring 16 achieves this. External pressure is applied to the auxiliary plate 3. After the movable rod 21 moves to the appropriate position and the first groove 141 cooperates with the second groove 24 to fix the moth in a specific space, the auxiliary plate 3 can be rotated to the upper side of the space formed by the first groove 141 and the second groove 24. This restricts the movement of the top of the moth and completely fixes it. Under the action of the pressure spring 16, pressure is applied to the auxiliary plate 3 to ensure that the auxiliary plate 3 will not rotate arbitrarily, ensuring the stability of fixing the moth. This further enhances the practicality and convenience of the experimental operation. To improve accuracy, a frame groove 32 is provided on the inner side of the plate 31. Several auxiliary rings 33 are fixed in the frame groove 32. The auxiliary rings 33 are arranged in an alternating manner, which may form a series of holes. When injecting moths after fixing them, the operator can align a hole with the location where the moth needs to be injected, hold the syringe in one hand, and place the needle tip directly on the side of the corresponding hole. This eliminates the need to hold the needle in one hand and support it with the other, further saving manpower and reducing the difficulty of the experiment.

Some parts and features of some embodiments may be included or replaced by parts and features of other embodiments. The embodiments of the present disclosure are not limited to the structures described above and shown in the accompanying drawings, and various modifications and changes may be made without departing from its scope.
