This sophisticated venom discharge mechanism makes the conventional bayonet-type muscle compression method of extracting venom ineffective, and it is difficult to achieve stable and effective venom extraction. In addition, the venom discharge mechanism of spiders in the order Araneae is usually accompanied by specific predation and defense behaviors, which further increases the uncertainty in the venom collection process. Therefore, new methods need to be developed for the venom collection of spiders in the order Araneae to ensure the safety and stability of venom collection.

[0043] Working principle: When extracting spider venom, place the spider in the tweezers body 801, and adjust the opening and closing degree of the tweezers body 801 by adjusting the limit bolt 807 to ensure that the spider is firmly clamped and will not be hurt. Hold the lighting pen 7 so that the lighting lamp 704 is turned on and the metal wire 703 is energized. Then, the metal wire 703 is brought into contact with the spider, so that current flows between the base 1, the lighting pen 7, the spider, the fixed tweezers 8, the connecting seat 6 and the base 1 to electrically stimulate the spider and make the spider produce venom. The spider venom is collected with the help of an external pipette. After the collection is completed, take the centrifuge tube 9 to collect the spider venom in the external pipette, and then place it in the quick-freezing placement hole 401 on the placement part 4. The spider venom in the centrifuge tube 9 is frozen to ensure its activity.

[0044] Specifically, when the spider is stimulated by means of the electrified metal wire 703, a variety of current sizes and click times can be used for adjustment. Regarding the selection of current size, in the actual test process, 9 Wuliangshan giant wart spiders of the same size and good growth condition under the same environment were selected, the control variable was the amount of water used to moisten the spider's chelicerae, which was one drop of a standard rubber-tipped dropper, the number of electric shocks was 4 times, each with an interval of 3 seconds, and 2 ml of ether was used for anesthesia for 15 minutes until the spider was obviously lazy. The specific conditions of obtaining venom under different currents in this case are shown in Table 1. Regarding the selection of the number of electric shocks, 6 Wuliangshan giant wart spiders of the same size and good growth condition under the same environment were selected, the control variable was the optimal current obtained by the experiment (with the first gear current in Table 1 as a reference), in the experiment of finding the number of motors when the venom output was the largest, each click was separated by 3 seconds, and in the comparison experiment of the venom output with the old continuous current venom extraction device, the venom was extracted for 21 seconds. The amount of water used to moisten the spider's chelicerae is one drop of a standard rubber-tipped dropper. This is the selection of different numbers of electric shocks, as shown in Table 2. Compared with the traditional method of spider venom extraction, the difference in the time used for spider venom extraction is shown in Table 3. When the first gear current in Table 1 is used and the current stimulation time is 21 seconds, the difference in spider damage is shown in Table 4. The spider venom taken in Table 2 was used for quality inspection and the difference is shown in Table 5.
