Abstract

The invention provides a wiring screwdriver for electricians. The wiring screwdriver comprises a grab handle and a screwdriver bar, wherein an oscillating circuit module and a battery structure which is used for supplying power to the oscillating circuit module are arranged in the grab handle; the screwdriver bar comprises a metal inner bar, a screwdriver head is formed on the end of the metal inner bar, a metal pipe surrounds the metal inner bar, and a gap between the metal inner bar and the metal pipe is filled with an insulating layer; the oscillating circuit module is electrically coupled with the metal inner bar, and the metal inner bar is used as an oscillating antenna; and the oscillating circuit module is matched with an on-off switch, an ampere meter which is used for detecting input current of the oscillating circuit module is arranged in a power supply line between the battery structure and the oscillating circuit module, and a display screen of the ampere meter is exposed to the surface of the grab handle. When a wire joint is connected to a binding post, the wiring screwdriver for the electricians can automatically detect whether the contact is good, so that the wiring efficiency and the wiring quality are increased.

Description

technical field [0001] The invention relates to the field of electric tools, in particular to an electrician wiring screwdriver. Background technique [0002] In the electrical wiring process, after the wire connector is inserted into the connection hole of the terminal post, it is usually necessary to use a screwdriver to tighten the wire bolt to compress the wire connector so that the wire connector maintains good electrical contact with the wire connector. However, due to the existence of the wire insulation shell, in the actual wiring process, if the experience is insufficient, the wiring bolt may be pressed to the wire insulation shell. In this case, although the wire joint is fastened by the wiring bolt, in fact Poor contact or even open circuit exists. Contents of the invention [0003] In view of the above problems, the purpose of the present invention is to provide an electrician wiring screwdriver, which can automatically detect whether the connection is good du...
