Problems solved by technology

[0004] The existing clamp-on ammeter has some disadvantages in use: when the clamp-on ammeter is in use, it is necessary to press the wrench to open the clamp head, and the measuring height is higher than the height of the user, and there is no advantage for the user to climb, and it is in a tight When the internal current of the wire is in the state, the user cannot press the wrench, which is troublesome to use. In order to solve the above problems, we propose a clamp ammeter

Abstract

The invention discloses a clip-on ammeter which comprises an ammeter body, one side of the ammeter body is rotatably connected with a wrench, the front end of the ammeter body is provided with a display screen, a switch is arranged the display screen at the front end of the ammeter body, and the lower end of the ammeter body is provided with a telescoping mechanism. The lower end of the telescoping mechanism is connected with a handle, the upper end of the ammeter body is provided with a clamping mechanism, the clamping mechanism comprises a first clamp head, the upper end of the first clamp head is rotatably connected with a rotating head, the rotating head is internally provided with a first rotating shaft, and the outer side of the first rotating shaft is provided with a pulley. The front end of the first clamp head is provided with a rotating mechanism, the rotating mechanism comprises a rotating rod, and the position, close to the upper end, of the rear end of the rotating rod is connected with a fixing rod. The clip-on ammeter is simple in structure, convenient to operate and capable of conveniently measuring the current of an electric wire at a high position.

Description

technical field [0001] The invention relates to the technical field of ammeters, in particular to a clamp ammeter. Background technique [0002] The clamp ammeter is composed of a current transformer and an ammeter. The iron core of the current transformer can be opened when the wrench is squeezed tightly. After the wrench is opened, the iron core is closed, and the measured circuit wire passing through the iron core becomes the primary coil of the current transformer, and the current is induced in the secondary coil through the current, so that the ammeter connected to the secondary coil has an indication to measure The current of the circuit under test. [0003] The invention patent with the application number: CN209043968U2 discloses a clamp-on ammeter, which relates to the field of current measurement. The elastic part for reset; the inside of the ammeter housing is provided with a cavity, the elastic part is arranged in the cavity, and the top of the adjustable wrench...
