Multifunctional telescopic measuring meter pen

Abstract

The invention provides a multifunctional telescopic measuring meter pen which comprises a pen body fixing part, a pen body telescopic part and a measuring needle. The pen body telescopic part is telescopically inserted in the pen body fixing part, and the measuring needle is inserted in the pen body telescopic part; according to the meter pen, the pen body of a conventional meter pen is divided into the pen body fixing part and the pen body telescopic part, telescopic extension of the pen body is achieved, the pen body is used at the normal length in the normal state, and when a long meter pen is needed under the necessary condition, a user can pull out the pen body telescopic part to enable the meter pen to be extended so as to complete effective measurement; the device can completely solve the technical problem that the measurement cannot be completed when the length of the measuring meter pen is insufficient, and has practical value and market prospect.

Description

technical field [0001] The invention relates to the technical field of electronic measuring instruments, in particular to a multifunctional telescopic measuring pen. Background technique [0002] The test leads used in the measuring equipment (multimeter, megohmmeter, ammeter, etc.) used to measure circuit faults cannot fully meet the needs of the work site. In the case that the measurement personnel cannot reach in, the length of the test pen is not enough to touch the measurement position, which makes the measurement difficult. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a multi-functional telescopic measuring probe, which is used to solve the problem that the probe is not long enough to effectively measure; [0004] The invention provides a multifunctional telescopic measuring pen, comprising a pen body fixing part, a pen body telescopic part and a measuring needle, the pen body telescopic part is retractably inserted into the p...
