When high-stool operation is required, the middle column is connected between the insulating stool seat board and the insulating stool bottom board; when low-stool operation is required, the middle column is removed, and the insulating stool seat board is stacked on the upper surface of the insulating stool bottom board; the structure of the present application is simple and reasonable in design, and can adjust the height according to the needs of different operations. Description of the drawings: The present invention will be further described below in conjunction with the drawings; Figure 1 and 2 are the three-dimensional structure schematic diagrams of two perspectives of the present invention; Figure 3 is the cross-sectional structure schematic diagram of the present invention. Detailed implementation manners: The present invention will be further described below in conjunction with the drawings and detailed implementation manners.

[0019] The structure of the movable insulating stool of the present invention includes an insulating stool seat board 1, an insulating stool bottom board 2, and a detachable intermediate column 3 provided between the insulating stool seat board 1 and the insulating stool bottom board 2. The insulating stool seat board and the insulating stool bottom board are circular plates with equal diameters or rectangles with rounded corners at the four corners.

[0020] The upper and lower ends of the intermediate column 3 are threadedly connected to the lower surface of the insulating stool seat board 1 and the upper surface of the insulating stool bottom board 2 through screws 4. Specifically, a boss 5 is provided on the lower surface of the insulating stool seat board 1, and a groove 6 corresponding to the boss for limiting is provided on the upper surface of the insulating stool bottom board. Threaded holes are provided at the central parts of the boss and the groove for threaded connection with the screw.

[0021] When high-stool operation is required, the intermediate column is connected between the insulating stool seat board and the insulating stool bottom board. When low-stool operation is required, the intermediate column is removed, and the insulating stool seat board is stacked on the upper surface of the insulating stool bottom board. For better positioning, through the cooperation of the boss and the groove, the insulating stool seat board and the insulating stool bottom board can be better centered and stacked for installation.

[0022] For convenient mobile use, a number of universal casters 7 are installed in the slot holes on the lower surface of the above-mentioned insulating stool bottom board. The universal caster 7 can be a commercially available caster with a brake. The upper end of the caster has a stud for connecting to the threaded slot hole on the lower surface of the insulating stool bottom board. When the universal caster 7 is not used, it is used for fixed or less mobile operations.

[0023] To increase the anti-slip effect, a number of concentric circular ring grooves 8 are provided on the upper surface of the above-mentioned insulating stool seat board.

[0024] Specifically, the diameter of the intermediate column is 80 mm and the length is 190 mm. The diameters of the insulating stool seat board and the insulating stool bottom board are 241, and the thicknesses are 27 mm and 30 mm respectively.

[0025] The insulating stool seat board, the insulating stool bottom board and the intermediate column of this application are processed from polypropylene PP material. The polypropylene PP material is non-conductive. The tool of this application can be widely used in 0.4 kV low-voltage power outage operations or live operations. The insulating stool of this application is movable and can be adjusted in height to adapt to different operation positions. A special wooden suitcase is designed and processed for the tool of this application. The wooden suitcase is filled with pearl cotton. There are circular grooves for placing the insulating stool seat board and the insulating stool bottom board and a long groove for placing the intermediate column on the pearl cotton. The insulating stool seat board, the insulating stool bottom board and the intermediate column are stored in the special toolbox, which has the advantages of moisture-proof, dust-proof and easy to carry. This tool is suitable for power outage or live operation personnel to use as a fixed or movable stool for the maintenance and repair operations of distribution station house power distribution cabinets, compensation cabinets and the low-voltage side of box-type transformers, which can effectively relieve the foot soreness and leg numbness of the operation personnel and improve the operation efficiency and safety.

[0026] After using the tool of this application, the operators reported that the use effect was good. Working while sitting for a long time was much easier than working while squatting, so there would be no symptoms of sore and numb feet, and there was no need to stand up and rest from time to time, which reduced the labor intensity of the operators, saved a large amount of manpower and time, and improved the safety of the operators.

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: the specific implementation manners of the present invention can still be modified or some technical features can be equivalently replaced; without departing from the spirit of the technical solutions of the present invention, they should all be covered by the scope of the technical solutions claimed by the present invention.
