Description

Technical Field

[0001] The utility model belongs to the technical field of detection instruments, and in particular relates to a detection instrument with stable wiring. Background Art

[0002] A measuring instrument is an instrument that can determine the magnitude of a measured variable. It can be a sensor, a transmitter, or an instrument that has both a detection element and a display device.

[0003] A multimeter is also a measuring instrument, capable of determining the magnitude of a measured variable. A multimeter is a multipurpose electronic measuring instrument primarily used in physics, electrical engineering, and electronics. It typically includes functions such as an ammeter (ammeter), a voltmeter (voltmeter), and an ohmmeter. While a multimeter is primarily designed to measure voltage, current, and resistance, it can also measure other physical quantities such as AC current, AC voltage, and audio levels. Multimeters are categorized by display type as either analog or digital. They are multifunctional, multi-range measuring instruments.

[0004] However, the test probe of the multimeter needs to be held in hand to contact the detection object. However, one hand needs to hold the test probe to contact the object to be detected, and the other hand cannot adjust the multimeter gear position at any time after contacting the multimeter, which makes the operation of the multimeter cumbersome.

[0015] Beneficial effects

[0016] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:

[0017] The utility model can be fixed to the device through the provided suction cup, and then the detection pen body is extended from the inside of the protective shell to contact the connection terminal of the device, thereby eliminating the need for manual operation of the detection pen structure in the detection instrument and making it possible to fix the device and the detection pen structure, thereby facilitating the detection of the device by the detection instrument;

[0018] When there is no need to use the detection pen structure of the detection instrument to detect the equipment, the protective shell is directly moved downward, and the protective shell retracts the detection pen structure into the interior of the protective shell. The protective shell is then fixed by the cooperation between the first guide groove, the second guide groove and the third guide groove, and the spring pulls the sealing block to seal the bottom, thereby preventing the detection pen body from being exposed to the air for a long time and causing the surface of the detection pen body to be corroded.
