Technical Field
[0001] The utility model relates to the technical field of capacitance guide needles, in particular to a high-efficiency vehicle-mounted capacitance guide needle. Background Art
[0002] With the rapid development of electronic information technology, the replacement speed of digital electronic products is getting faster and faster. As the production and sales of electronic products continue to grow, the capacitor industry is also growing. A capacitor is a component that can store electric charge and is one of the most commonly used electronic components. Capacitors play an important role in circuits such as tuning, bypassing, coupling, and filtering. A capacitor is a component that can store electric charge and is one of the most commonly used electronic components. Any two conductors (including wires) that are insulated from each other and very close to each other constitute a capacitor. The capacitor is connected to other circuits through capacitor pins. The basic function of a capacitor is charging and discharging, but due to the many circuit phenomena that extend from this basic charging and discharging function, capacitors have a variety of different uses. Capacitor pins are one of the important components of a capacitor.
[0003] The front end of the existing capacitor guide pin is easily bent when in use, which makes the capacitor unusable. The guide pins often used in capacitors are of an integrated structure, and the capacitor needs to be opened when replaced, which makes the process of replacing the guide pins very troublesome.

[0015] Beneficial effects
[0016] The present invention provides a highly efficient vehicle-mounted capacitive guide needle, which has at least the following beneficial effects compared to the prior art:
[0017] Pulling the pull block upward compresses the spring, driving the connecting rod upward. This in turn drives the piston upward, extracting the air from the sealing ring, causing it to shrink and disengage from the stop slot. The guide pin can then be twisted out. A new guide pin is screwed into the aluminum stem. Release the pull block, which moves downward under the action of the spring. The spring then moves the piston downward, pressing the air from the sealing cylinder into the positioning slot, causing the sealing ring to expand and limit the stop slot. This locks the guide pin for easy use. BRIEF DESCRIPTION OF THE DRAWINGS
