[0021] By opening the inner groove 4 in the inner cavity of the insulating sleeve 1 and installing the color display board 5 in the inner cavity of the inner groove 4, during the normal use of the insulating sleeve 1, the outer wall of the insulating sleeve 1 will contact the ground, thereby generating friction, thereby making the outer wall of the insulating sleeve 1 thinner. When the outer wall of the insulating sleeve 1 is continuously worn, the color display board 5 will be exposed from the inner cavity of the insulating sleeve 1, and the color display board 5 will be in contact with the air.

[0022] In a preferred embodiment, the shape of the inner wall of the inner groove 4 matches the shape and size of the outer wall of the color display plate 5 , the insulating sleeve 1 is made of PVC, and the outer wall of the insulating sleeve 1 is orange in color.

[0023] By opening the inner groove 4 in the inner cavity of the insulating sleeve 1 and installing the color display board 5 in the inner cavity of the inner groove 4, during the use of the insulating sleeve 1, the outer wall of the insulating sleeve 1 will gradually become thinner due to wear, so that the outer wall of the color display board 5 is exposed, so that the outer wall of the color display board 5 is in full contact with the air, and the insulating sleeve 1 made of PVC material has better softness and elasticity, which is more convenient for users to retract and release, and the elastic PVC material has good tensile strength and wear resistance.

[0024] In a preferred embodiment, the color developing plate 5 is made of polyurethane foam, and the inner cavity of the color developing plate 5 is filled with polyphenol oxidase liquid.

[0025] The color developing board 5 is made of polyurethane foam, so that the color developing board 5 has good adsorption properties, so that a certain amount of polyphenol oxidase can be adsorbed in the inner cavity of the color developing board 5. The polyphenol oxidase will oxidize and change color after contacting the air, thereby changing the color of the color developing board 5. When the color of the color developing board 5 changes, the user can be reminded in time.

[0026] In a preferred embodiment, the outer walls of the limiting ring 8 and the supporting ring 9 are both in arc shape, and the outer walls of the limiting ring 8 and the supporting ring 9 are in contact with the outer walls of the neutral line 2 and the live line 3 respectively.

[0027] By setting a support ring 9 and a limit ring 8 in the inner cavity of the insulating sleeve 1, and blocking the limit ring 8 and the support ring 9 through a support rod 7 set between the limit ring 8 and the support ring 9, when the outer skin of the insulating sleeve 1 and the neutral wire 2 and the live wire 3 are damaged, in order to avoid contact between the outer walls of the neutral wire 2 and the live wire 3, the neutral wire 2 and the live wire 3 can be effectively separated under the blocking of the support rod 7, avoiding contact between the neutral wire 2 and the live wire 3 to cause a short circuit.

[0028] In a preferred embodiment, the support rod 7 , the limiting ring 8 and the supporting ring 9 are all made of ABS plastic, and a rubber anti-slip pad is installed on the outer wall of the limiting ring 8 facing the neutral line 2 .

[0029] The support rod 7 and the limiting ring 8 and the supporting ring 9 made of ABS plastic can have better use strength during use, better separate the neutral wire 2 and the live wire 3, better support the neutral wire 2 and the live wire 3, and avoid contact between the outer walls of the neutral wire 2 and the live wire 3.

[0030] In a preferred embodiment: the outer walls of the neutral wire 2 and the live wire 3 are both covered with an insulating layer, the insulating layer of the outer wall of the neutral wire 2 is blue, and the insulating layer of the outer wall of the live wire 3 is red.

[0031] By setting an insulating layer on the outer walls of the neutral wire 2 and the live wire 3, when using the neutral wire 2 and the live wire 3, since the colors of the insulating layers on the outer walls of the neutral wire 2 and the live wire 3 are different, the neutral wire 2 and the live wire 3 can be clearly distinguished by color, making it more convenient to distinguish the neutral wire 2 and the live wire 3.

[0032] Working principle: During the use of the above-mentioned equipment, during the use of the insulating sleeve 1, the inner groove 4 is opened in the inner cavity of the insulating sleeve 1, and the color display board 5 is installed in the inner cavity of the inner groove 4. When the outer wall of the insulating sleeve 1 is worn and thinned during use, the color display board 5 will come into contact with the air. At this time, the polyphenol oxidase adsorbed in the inner cavity of the color display board 5 will come into contact with the air, thereby producing a color change reaction, so that the outer wall of the color display board 5 becomes black as a whole, so as to remind the user that the outer wall of the insulating sleeve 1 is damaged, and the outer wall of the insulating sleeve 1 is processed in time. Once the outer wall of the insulating sleeve 1 and the outer walls of the neutral wire 2 and the live wire 3 are damaged, under the action of the support rod 7 and the limit ring 8 and the support ring 9, the outer wall of the neutral wire 2 can be separated from the outer wall of the live wire 3 to avoid contact between the neutral wire 2 and the live wire 3, thereby preventing a short circuit from occurring inside the insulating sleeve 1, further reducing the safety risk of use.

[0033] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
