Household multi-angle bending electroscope capable of digital display

Abstract

The invention discloses a household multi-angle bending electroscope capable of digital display. The electroscope comprises a penholder, the external surface of the front end of the penholder is provided with a digital display screen, a neon lamp is fixedly mounted in a position, close to one side of the digital display screen, in the external surface of the front end of the penholder, an angle knob is movably mounted in a position, close to the other side of the digital display screen, in the external surface of the front end of a casing, an induction measuring button is movably mounted in aposition, close to one side of the neon lamp and far from the other side of the digital display screen, in the external surface of the front end of the casing, and a direct measuring button is arranged in a position at one side of the induction measuring button and far from one side of the neon lamp. The household multi-angle bending electroscope capable of digital display can be connected with anexternal universal meter while electroscoping to display measured voltage and current and compare the voltage and current with those in a digital display screen, the precision of digital display canbe compared, simple maintenance of circuits can be carried out conveniently via tools in an auxiliary tool groove, an angle between the penholder and an extended rod can be adjusted, the length of a screwdriver head rod can be adjusted, and illumination can be provided during dark light at night.

Description

technical field [0001] The invention relates to the field of electroscope pens, in particular to a digital display multi-angle bendable electroscope pen for household use. Background technique [0002] The electroscope pen is a common electric inspection tool in daily life. Most of the existing electroscope pens do not have a digital display function, and can only be used to check whether the line is charged, and cannot be used to detect the magnitude of the voltage. There will also be some errors in the value, and the test results are not very accurate. In the case of power failure, when the light is dark, it is very troublesome to test the electricity, and the area of ​​the electricity inspection cannot be accurately found. In addition, when the circuit fails, it is necessary to It takes time to find tools for simple maintenance of the circuit. For special situations, most of the test pens cannot be adjusted. The test pens cannot be bent and cannot be used for special cas...

Most of the existing electroscope pens do not have a digital display function, and can only be used to check whether the line is charged, and cannot be used to detect the magnitude of the voltage. There will also be some errors in the value, and the test results are not very accurate. In the case of power failure, when the light is dark, it is very troublesome to test the electricity, and the area of ​​the electricity inspection cannot be accurately found. In addition, when the circuit fails, it is necessary to It takes time to find tools for simple maintenance of the circuit. For special situations, most of the test pens cannot be adjusted. The test pens cannot be bent and cannot be used for special conditions. The length of the head rod is fixed and cannot be adjusted, which also makes the electroscope pen not adjustable
