Improved, the end, upper end of described first sleeve pipe is provided with groove, and the end, lower end of described second sleeve pipe is provided with the projection that matches with described groove, and described projection is fixedlyed connected by screw with groove.
Improved, described pipe is fixedlyed connected by screw with second sleeve pipe.
Improved, described pipe is fixed on the straight-bar by supporting seat.Fix more firmly.
Improved, the lower end of described cylinder footing is provided with anti-skidding footmuff.Play anti-skidding effect.
Improved, described straight-bar and step on and be provided with diagonal brace between the bar.Strengthen the bearing capacity of stepping on bar.
Improved, the top of the terraced body of described list is provided with the pole band, and described pole band is fixed between two straight-bars.Be used for buckling operating personnel's safety belt, prevent from operation process, taking place high falling.
Beneficial effect:
After adopting technique scheme, the improved insulating ladder bottom stud structure of this utility model adapts to the ground of various situations by the height of footing component adjusting insulating ladder straight-bar bottom, guarantee the stability of insulating ladder, step on the rod bending function admirable, be difficult for torsional deformation, safe and reliable.
