Face.
The beneficial effect of the first above-mentioned technical scheme is：Electrician's line connection screwdriver is connect screwing connection bolt
During line, the oscillating circuit module work, and by the inner metal rod of the knife bar is shielded by its peripheral metal tube
Cover, cause the vibration antenna that the electromagnetic energy in oscillating circuit module can not be by being made up of the inner metal rod to external radiation, make
Oscillating circuit module only keeps small input current；And when connection bolt compresses power lug completely, keep well electrical
During contact, the inner metal rod of knife bar is by connection bolt and long wire electrical communication, so that wire constitutes the vibration electricity
The vibration antenna body of road module, so that the electromagnetic energy in oscillating circuit module is outwards largely radiated by long wire, so that
The input current of oscillating circuit module is dramatically increased, and with the fastening of power lug, input current is stable in saliency value；By
This, can determine whether to have completed good wiring operation.
The present invention solves second of technical scheme being used of its technical problem：Electrician's line connection screwdriver includes holding
Handle, knife bar；Provided with an oscillating circuit module in the lever, and it is the battery structure of the oscillating circuit module for power supply；Institute
The inner metal rod that knife bar forms driver bit including end is stated, inner metal rod periphery surrounds a metal tube；Inner metal rod and gold
Insulating barrier is filled between category pipe；Inner metal rod described in the oscillating circuit module electrical couplings, and using inner metal rod as shaking
Swing antenna；The oscillating circuit module, which is equipped on on-off switch, the lever, is additionally provided with reception electric wire, the reception antenna electricity
Property be coupled in the input of wireless receiving module in lever, the output end of the wireless receiving module is coupled on the lever
LED light.
Further, the output end of the wireless receiving module passes through defeated to the LED light after rectification filtering module
Go out direct current；And the LED light is connected with a Zener diode, make the direct current of the rectification filtering module output
Pressure needs just light the LED light after Zener diode described in reverse breakdown；So that the wireless receiving module is received
When the wireless signal arrived is sufficiently strong, it can just light LED light, i.e. as long as LED light is lighted, then wiring quality is just sufficient
Reach, difficulty is judged with the reduction for further docking line mass.
The beneficial effect of above-mentioned second of technical scheme is：Equally, before consistent termination is not completed, the vibration electricity
The electromagnetic energy of road module causes the wireless receiving module to be only capable of receiving faint electromagnetic signal by the metal tube shield,
Or even no signal；And when connection bolt compresses power lug completely, when keeping good in electrical contact, in oscillating circuit module
Electromagnetic energy is outwards largely radiated by the wire in connection circuit, so that the output of the wireless receiving module is significantly increased,
And light the LED light；Thus, it can determine whether to have completed good wiring operation.
