[0028] In this embodiment, when the bottom end of the first spring 18 touches the feeler 2, the rotating shaft 20 is slidably connected inside the slide groove of the second telescopic rod 21, and the bottom end of the second telescopic rod 21 is fixed to the sliding block 23 by welding. The outer side of the sliding block 23 is slidably connected with a connecting frame 26, and the connecting frame 26 is tightly pressed against the inside of the electric pen housing 1. At this time, the buzzer 12 makes a sound and the signal source 7 lights up, thereby realizing the function of reminding the staff.

[0029] Example 2

[0030] like Figure 3 to Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a buzzer 12 is arranged inside the electric pen housing 1, the bottom end of the buzzer 12 is electrically connected to an induction coil 13, the bottom end of the induction coil 13 is electromagnetically connected to an electromagnetic group 14, the electromagnetic group 14 is rotatably connected inside the electric pen housing 1, the bottom end of the electromagnetic group 14 is provided with an LED lamp 15, the top end of the electric pen housing 1 is fixedly connected with a buckle 4, the outer side of the electric pen housing 1 is sleeved with a pen clip 3, the pen clip 3 is set to a rubber material, the front end of the electric pen housing 1 is fixedly connected to a display screen 5, the bottom end of the display screen 5 is fixedly connected to a search button 6, the search button 6 is fixedly connected to the search button 6, and the search button 6 is fixedly connected to the search button 6. The bottom end of the search button 6 is fixedly connected to the signal source 7, and two groups of search buttons 6 are provided. The bottom end of the electric pen housing 1 is fixedly connected to the pen cap 11, and the bottom end of the pen cap 11 is rotatably connected to the conversion joint 10, and the bottom end of the conversion joint 10 is rotatably connected to the fixing frame 8, and the bottom end of the fixing frame 8 is fixedly connected to the test head 9, and a circular groove is provided inside the fixing frame 8, and a night light 25 is provided inside the circular groove of the fixing frame 8, and a notch is provided inside the LED lamp 15, and a transistor 24 is embedded and connected inside the notch of the LED lamp 15, and the bottom end of the transistor 24 is fixedly connected to the night light 25, and two groups of night lights 25 are provided.

[0031] In this embodiment, when testing different wiring harnesses, the signal is amplified by the transistor 24, and the LED light 15 is connected through the transistor 24 to determine the live wire and the neutral wire.

When the test head 9 captures a short-circuited wiring harness, it can vibrate in real time to remind the maintenance personnel to quickly repair the problem.

[0032] The working principle of this utility model:

[0033] First, the staff member pulls the pen cap 11 out of the bottom end of the electric pen housing 1, holds the electric pen housing 1, places the test head 9 in the palm of the hand, and observes the value on the display 5, makes a judgment based on the value, and completes the self-check before measuring the electric pen.

[0034] After the self-test of the electric pen is completed, the test head 9 is inserted into the place to be tested. When the power is turned on, the wire will generate a magnetic field. Since it is connected to 220V AC, it generates a constantly changing magnetic field. In a closed loop, cutting the magnetic flux lines can generate current. At this time, the electric pen is placed near the line, and the constantly changing magnetic field is equivalent to the test head constantly cutting the magnetic flux lines, so a current signal is generated and transmitted to the inside of the electric pen. However, this signal is very weak. The signal is amplified by the transistor 24, and the LED lamp 15 is connected through the transistor 24 to determine the live wire and the neutral wire. When the LED lamp 15 lights up and touches the live wire, the human body is equivalent to a capacitor, thus forming a loop.

[0035] When testing in a dimly lit place, turn on and press the button at the bottom of the display 5. At this time, the night light 25 inside the fixed frame 8 illuminates the construction environment, thereby facilitating maintenance. When testing the circuit, the detection head 9 is damaged. At this time, the partition 16 squeezes the first telescopic rod 17 to move in the direction of the feeler 2. When the feeler 2 tilts to the left, it also drives the rotating frame 19 to tilt to the left. The shaft 20 slides in the slide groove inside the second telescopic rod 21. At this time, the sliding block 23 tilts to the right. When the sliding block 23 touches the inner wall of the electric pen housing 1, the signal source 7 is triggered, thereby achieving rapid power off, thereby protecting the safety of maintenance personnel.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
