Embodiment Construction

[0009] Such as figure 1 A small acousto-optic low-voltage test pen, including a sensor cap 1, an acousto-optic device 2, an electromagnetic board 3, and an electric measuring head 4. There are acousto-optic devices 2, an electromagnetic board 3, and an acousto-optic device 2 in the pen holder. It is mainly composed of a small light bulb and a small loudspeaker, and is powered on when the sensor crown 1 is pressed.

[0010] The sensor crown is made of plastic material, and the measuring head is made of conductive material.

[0011] With the above structure, when in use, by adopting the above structure, there is an acousto-optic device and an electromagnetic board installed in the electric measuring pen holder. The acousto-optic device is mainly composed of a small bulb and a small loudspeaker. Reach the function of reminding.

Abstract

A small acousto-optic low-voltage test pen, including a sensor cap, a sound-light device, an electromagnetic board, a power-measuring head, and an acousto-optic device and an electromagnetic board installed in the pen holder. The acousto-optic device is mainly composed of a small light bulb and a small loudspeaker When the sensor crown is pressed, it is energized to achieve a reminder function.

Description

technical field [0001] The invention belongs to the field of living equipment, and in particular relates to a small acousto-optic low-voltage test pencil. Background technique [0002] Existing electric test pens do not make sound, have weak light, are difficult to see clearly, or only have fixed numbers, or the identification of live wire and neutral wire is confused, and the test is inaccurate. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a small acousto-optic low-voltage test pen, which can solve the problem that the existing test pen does not make sound, the light is weak, it is difficult to see clearly, or there are only fixed numbers, or the live line and neutral line are confused, and the test is not accurate. In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: [0004] A small acousto-optic low-voltage test pen, including a se...
