At the same time, it eliminates the need for climbing, reducing the safety risks of climbing to high places for electroscope testing, and making it convenient to use.

[0038] The portable and extendable voltage detector of this utility model is used as follows: Determine the operating position based on the required wire location, place the adjusting base 4 in the operating position, adjust the included angle of the two legs 444 in the bracket 44, and fix the adjusted legs 444 with fastening bolts 442. Adjust and place the adjusting base 4 stably. Test the voltage detector body 3 to determine if it is working properly. After inspection, rotate the storage cover 8 to separate it from the handle 1. Pull out multiple telescopic units 21 sequentially through the storage cover 8, and limit and fix each telescopic unit 21 by pulling out, rotating, and pressing it down. After the telescopic unit 21 is fixed, insert the handle 1 into the telescopic cylinder 41. Hold the handle 1 with one hand to adjust its height at any time, and grasp the handle 47 with the other hand. Pull the locking pin 46 out of the fixing hole 445 through the handle 47. Rotate the turntable 45 through the locking pin 46. The turntable 45 drives the rotating shaft 43 and the telescopic cylinder 41 to rotate. At the same time, observe the position of the voltage testing body 3. When the voltage testing body 3 rises to contact the wire, obtain the continuity of the wire through the reaction of the voltage testing body 3. When it is necessary to test the working status of the wire at different positions, rotate the turntable 45 by a certain angle through the locking pin 46 to make the voltage testing body 3 in a state of non-interference with the wire. Push the locking pin 46 through the handle 47 to insert the locking pin 46 into the fixing hole 445. After adjusting the placement of the bracket 44, pull out the locking pin 46 and continue to adjust the angle of the turntable 45, so that the voltage testing body 3 can continue to work. After the test is completed, retract the telescopic component 2 and store and fix the telescopic component 2 through the handle 1 and the storage cover 8. Rotate the support leg 444 to complete the storage of the adjustment base 4. During the voltage testing process, the height of the voltage testing body 3 can be controlled by raising and lowering the handle 1. When the handle 1 is pressed down, the sliding plate 49 moves downward in the mounting hole 411, pressing down the telescopic spring 42. At this time, the voltage testing body 3 moves down, reducing the downward force on the handle 1. Under the action of the telescopic spring 42, the handle 1 is raised a certain distance, and the voltage testing body 3 rises accordingly.
