[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0019] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0020] In this embodiment, refer to Figure 1 and Figure 3 Specifically, it includes an insulating arm A1, an insulating arm B2, a locking screw 5, and a torsion spring 6. The locking screw 5 connects the middle parts of the insulating arm A1 and the insulating arm B2 together. The torsion spring 6 is sleeved on the locking screw 5, and its two ends abut against the insulating arm A1 and the insulating arm B2 respectively. Both the insulating arm A1 and the insulating arm B2 are made of polytetrafluoroethylene material. Both the insulating arm A1 and the insulating arm B2 are in an insulated state to avoid leakage and facilitate operation by the staff.
[0021] In this embodiment, refer to Figure 1 and Figure 2 Insulating arms A1 and B2 are respectively provided with a first receiving groove 7 and a second receiving groove 8 on opposite sides to facilitate the laying of wires. A boss 10 is provided in the second receiving groove 8. The boss 10 is located at the head of the insulating arm B2 and is clearance-fitted with the first receiving groove 7. The boss 10 provides limiting guidance when the insulating arms A1 and B2 move closer or further apart. A through hole 12 is provided on the boss 10 and communicates with the second receiving groove 8. The discharge resistor 4 is installed in the through hole 12. At the same time, two conductive arms 3 are respectively installed at the tail of the first receiving groove 7 and the second receiving groove 8 by screws. The discharge resistor 4 is connected to the two conductive arms 3 by wires. The wires are respectively laid in the first receiving groove 7 and the second receiving groove 8, so that the discharge resistor 4 is electrically connected to the two conductive arms 3 to form a discharge circuit.
[0022] In this embodiment, refer to Figure 1 The contact end of the conductive arm 3 is provided with an extension 11, which increases the contact area between the component and the conductive arm 3, preventing other parts of the conductive arm 3 from interfering with the component. It is also suitable for discharging components of different sizes, avoiding poor contact.
[0023] In this embodiment, refer to Figure 1 A limiting screw 9 is inserted at the first end of the insulating arm B2, and the limiting screw 9 points to the insulating arm A1. By rotating the limiting screw 9, the opening and closing distance between the insulating arm A1 and the insulating arm B2 can be adjusted, thereby realizing the adjustment of the opening and closing distance between the two conductive arms 3, which is used to discharge components of different sizes.
[0024] In this embodiment, the overall weight of the structure is between 40-70g, which facilitates operation by staff and ensures a good feel.
[0025] The working principle of this embodiment is as follows: By rotating the limiting screw 9, the opening and closing distance between the insulating arm A1 and the insulating arm B2 is adjusted and limited, and the opening and closing distance between the two conductive arms 3 is also adjusted and limited, so that the opening and closing distance between the two conductive arms 3 is adapted to the size of the component to be discharged. The component is discharged through the discharge resistor 4. At the same time, the discharge resistor 4 can also be replaced, which is suitable for components that do not have different discharge standards. This structure is used to adjust components of various sizes, has a wide range of applications, and is easy to operate.
