An electricity testing pen capable of increasing friction

Abstract

The invention discloses an electricity testing pen capable of increasing friction. The electricity testing pen comprises an insulating cylinder which is hollow inside and is provided with openings at the two ends of the insulating cylinder. One opening end of the insulating cylinder is provided with a button. One end of the button is disposed in the opening end. The button can move in the opening end. A groove is disposed on the outer wall of the insulating cylinder and is bestrewn on the outer wall of the insulating cylinder in a helical line manner. The electricity testing pen has the advantages of simple structure and easy use. The design of the groove enables a user to be capable of conveniently and firmly holding the electricity testing pen so as to reduce dropping probability and increase work efficiency.

Description

technical field [0001] The invention relates to an electroscope, in particular to an electroscope capable of increasing the friction function, belonging to circuit detection equipment. Background technique [0002] Electricity is a natural phenomenon, a kind of energy. Lightning in nature is a phenomenon of electricity. Electricity is a property that creates repulsive and attractive forces between subatomic particles like electrons and protons. It is one of the four fundamental interactions in nature. There are two kinds of electricity or charge: we call one positive electricity and the other negative electricity. Through experiments, we found that charged objects repel like-sex and opposite-sex attract, and their attraction or repulsion obeys Coulomb's law. Electricity is a general term that includes a wide variety of phenomena arising from the presence or movement of electrical charges. There are many easily observed phenomena, such as lightning, static electricity, e...

Problems solved by technology

In daily testing, due to the need to hold the electroscope pen in hand, the inspector sometimes needs to carry out testing on high-altitude lines. When working for a long time, the palm of the hand has sweat or other things, which may easily cause the electroscope pen to slip and cause the work to remain unchanged.
