[0020] The following is combined with Figure 4The utility model is further described with implementation modes.

[0021] An electric power testing device for electric power engineering, comprising a support rod 6, one end of the support rod 6 is fixedly connected to a cross bar 3, two ends of the cross bar 3 are respectively provided with grooves 31, one end of a bending rod 2 is respectively arranged in each of the grooves 31, one end of each bending rod 2 is rotatably connected to the cross bar 3, and the other end of each bending rod 2 is respectively fixedly connected to a probe 1, and the probe 1 is used for actual current detection;

[0022] The bending rod 2 is connected to the driving assembly.

[0023] The driving assembly includes an electric push rod 5, a moving ring 4 and a connecting rod 10. One end of the connecting rod 10 is hinged at the bending part of one side of each bending rod 2, and the other end of each connecting rod 10 is hinged to an ear block 11. The two ear blocks 11 are fixedly connected to the moving ring 4. The moving ring 4 is looped over the support rod 6, and the moving ring 4 and the support rod 6 match each other.

[0024] The outer end of the support rod 6 is inserted into the sleeve 9, and the sleeve 9 is provided with a thread on the outside of one end near the support rod 6. The sleeve 9 is connected with the knob 8 through the thread. The end of the sleeve 9 near the support rod 6 is fixed with elastic clips 7 evenly arranged around the circumference. The outer wall of the elastic clip 7 is arc-shaped. The knob 8 can lock the elastic clip 7 to fix the support rod 6.

[0025] The knob 8 includes an annular member 81 and a conical ring 82 . The annular member 81 fixes the conical ring 82 . The conical ring 82 can lock the elastic clip 7 . The annular member 81 and the sleeve 9 are connected by threads. The annular member 81 is arranged at one end away from the electric push rod 5 .

[0026] The support rod 6 is embedded with an alarm, and when the probe 1 detects current, the alarm sounds an alarm to prompt the operator.

[0027] In this embodiment, the outer walls of the sleeve 9 , the knob 8 and the support rod 6 are all covered with an insulating layer.

[0028] Specifically, insert the outer end of the support rod 6 into the sleeve 9, determine the length of the support rod 6 extending out of the sleeve 9, and then determine the entire length of the device, which is convenient for testing the electricity at test points of different heights, and then lock the elastic clip 7 by the knob 8 to fix the support rod 6, start the electric push rod 5, and the telescopic rod of the electric push rod 5 extends to drive the moving ring 4 to move, and the moving ring 4 drives the connecting rod 10 to swing, and the connecting rod 10 drives the bending rod 2 to fix one end of the probe 1 to swing outward and open, and the probe 1 approaches the area to be detected, and the telescopic rod of the electric push rod 5 is controlled to retract to drive the probe 1 to swing in the opposite direction to close and clamp the position to be detected for detection.
