[0002] A microelectrode fabrication apparatus is an experimental device used to fabricate microelectrodes. Microelectrodes are commonly used in fields such as neuroscience, cell biology, and electron microscopy, primarily for the precise recording and stimulation of the activity of individual cells and neurons.

[0003] The working principle of the microelectrode pulling instrument is to heat a thin glass tube and apply appropriate tension to stretch it into a very thin electrode with a specific size.

The bottom of the fixed plate a9 is fixedly connected to the top of the drawing instrument body 1. The spring arc plate 10 is fixedly connected to the outside of the fixed plate a9. The spring arc plate 10 is used to limit the movement range of the protective shell 3 to ensure its stability and reliability. A limiting groove 8 is fixedly connected to the outside of the protective shell 3. The limiting groove 8 is used to further limit the movement range of the protective shell 3 to ensure its stability and reliability. The outside of the limiting groove 8 is slidably connected to the outside of the spring arc plate 10.

[0036] The external fixed connection of the drawing instrument body 1 includes a limiting component, which includes two connecting posts 11. The connecting posts 11 are cylindrical in shape and are used to support and fix the rubber blocks 12. One end of the two connecting posts 11 is fixedly connected to the outside of the drawing instrument body 1.

The inside of the protective shell 3 is opened with a circular groove that matches the rubber blocks 12. The outer surfaces of the two rubber blocks 12 are slidably connected to the inner groove of the protective shell 3.

[0037] Reference Figure 1 , Figure 4 and Figure 5The drawing instrument body 1 is internally fixedly connected to a fixed plate b13. A filter mechanism is fixedly connected to the top of the fixed plate b13. The filter mechanism includes a filter plate 14, which is rectangular in shape and is used to filter impurities generated during the drawing process. The bottom of the filter plate 14 is fixedly connected to the fixed plate b13. A U-shaped plate 15 is fixedly connected to the top of the fixed plate b13. The U-shaped plate 15 is U-shaped and is used to support and fix the sliding plate 18. The sliding plate 18 is rectangular in shape and is internally slidably connected to the sliding plate 15. Multiple brushes 19 are fixedly connected to the outside of the sliding plate 18. The brushes 19 are long and strip-shaped and made of soft bristles. They are used to clean the filter plate 14 and ensure the filtration effect. The multiple brushes 19 are externally slidably connected to the outside of the filter plate 14. The outside of the filter plate 14 is externally slidably connected to the outside of the scraper 20. The scraper 20 is rectangular in shape and is fixedly connected to the outside of the sliding plate 18. It is used to further clean the filter plate 14 and ensure the filtration effect.

[0038] An elastic component is fixedly connected to the lower inner end of the U-shaped plate 15. The elastic component includes a telescopic column 16, which is cylindrical in shape and is used to provide elastic support to ensure the stability and flexibility of the sliding plate 18. One end of the telescopic column 16 is fixedly connected to the lower inner end of the U-shaped plate 15, and the other end is fixedly connected to the bottom of the sliding plate 18. A spring b17 is sleeved on the outside of the telescopic column 16. The spring b17 is used to provide elastic force to ensure the stability and flexibility of the sliding plate 18. One end of the spring b17 is fixedly connected to the bottom of the sliding plate 18, and the other end is fixedly connected to the lower inner end of the U-shaped plate 15. A collection box 22 is placed in the groove inside the fixed plate b13. The collection box 22 is rectangular in shape and is used to collect impurities generated during the filtration process to ensure the cleanliness of the inside of the drawing instrument. Two fans 21 are fixedly connected inside the drawing instrument body 1. The fans 21 are used to provide airflow to accelerate the discharge of impurities during the filtration process and ensure the cleanliness of the inside of the drawing instrument.

[0039] Working principle: First, the operator applies an upward force to the protective shell 3, causing the circular groove inside the protective shell 3 to disengage from the rubber block 12. At this time, the spring a5 elastically retracts through the linkage of the fixed column a4 and the fixed column b7, causing the protective shell 3 to rotate upward around the fixed block 2. When the protective shell 3 is fully rotated and opened, pressing the protective shell 3 causes the arc surface of the rebound arc plate 10 to engage with the limiting groove 8, maintaining the stability of the open state. When closing, the operator presses the top of the protective shell 3 to make it rotate downward, causing the rubber block 12 to embed into the circular groove of the protective shell 3 to achieve secondary locking, and the spring a5 is stretched to the initial state.

[0040] The sliding plate 18 is pressed down so that it moves vertically downward along the inner wall of the U-shaped plate 15. During this process, the spring b17 is compressed under the guidance of the telescopic column 16, while the brush 19 moves with the sliding plate 18 to brush the surface of the filter plate 14. At the same time, the scraper 20 scrapes away the stubborn dust attached to the mesh of the filter plate 14. After cleaning, the sliding plate 18 is released, and the spring b17 pushes it back to the initial position. The removed dust is accelerated by the airflow generated by the fan 21 through the guide channel of the fixed plate b13 and finally falls into the collection box 22 for centralized treatment.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
