In addition, a balancing device is further installed between the upper top plate 12 and the lower bottom plate 13, so that the electric pole to be detected is prevented from violently shaking in the detection process to influence the detection result. Of course, the structure of the test stand 1 is not limited thereto.
The adjustable clamp 2 includes a fixed portion 21 and a movable portion 22. The fixing portion 21 is mounted at an end of the support housing 11, and specifically includes a fixing base 211 mounted on the support housing 11 and a fixing rod 212 mounted on the fixing base 211, where an annular fixing block is disposed at an end of the fixing rod 212.

The S-shaped force sensor is arranged between the slide block 41 of the linear driving part 4 and the fixed clamp 3 and is used for detecting each performance parameter of the electric pole to be tested.
The display part 6 is connected with the detection part 5 and is mainly used for collecting and displaying various performance parameters of the electric pole to be tested. Specifically, the display unit 6 is mounted on the side surface of the support housing 11, and is integrated with the control switch and the control button.
