The limiting member is used to limit the trolley body 1 and the telescopic body 4 so that there is a predetermined size of accommodation space between the first baffle and the second baffle, and the DC voltage measuring device is arranged in the accommodation space formed between the first baffle and the second baffle.

[0032] In a preferred embodiment of the present application, Figure 2 As shown, the movable slide groove 7 of the trolley body 1 is cross-shaped, and the top and bottom of the sliding connection part between the telescopic body 4 and the trolley body 1 are symmetrically arranged with limit sliders 8, and the telescopic body 4 and the limit sliders 8 together form a cross-shaped cross section.
