[0027] In the utility model, when in use, the side plate 1 is installed inside the power distribution cabinet, and is connected and fixed by bolts, and then the threaded through-tube 2 is threadedly connected to the inside of the side plate 1, so as to control the depth of the threaded through-tube 2 extending into the inside of the power distribution cabinet, and then the other end of the threaded through-tube 2 is installed through the incoming line through-tube 3. At this time, the guide is passed through the incoming line through-tube 3 and the inside of the threaded through-tube 2, and finally the guide is introduced into the power distribution cabinet. When the wire enters the incoming line through-tube 3, the wire is passed through the support plate 4 and the telescopic airbag 7 in sequence, and the support plate 4 is used to The wires are supported and guided. When the wires are installed in the distribution cabinet, the gas injection component 5 works to make the lifting component 6 work, which in turn drives the support plate 4 to work.
