[0002] An electroscope is an instrument that detects whether an object is charged and roughly estimates the amount of charge. Its typical structure is shown in the figure on the left. When the object being tested touches the conductor at the top of the electroscope, the charge it carries will be transferred to the foil in the glass bell jar. Since charges of the same kind repel each other, the foil will automatically separate and open at a certain angle. When checking the conductor, the electroscope will be used to detect the conductor to determine whether the conductor is charged and to treat the conductor according to the charged condition.

Then the assembly operation of the protective component is completed, so that the protective cover can protect the tester. By providing the protective component, the contact end of the electroscope can be protected, thereby reducing the problem that the contact part of the electroscope is exposed to the outside and easily damaged when the electroscope is put away, and further improving the protection of the electroscope itself.
