[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0022] The utility model provides a technical solution, please refer to Figure 1-3 :

[0023] A double-layer insulated power cord includes a wire body 1, the wire body 1 is fitted with an arc groove 15 provided on a protective shell 14 and an arc groove 2 10 provided on a protective shell 2 9, a card slot 6 is provided on the protective shell 14, a card block 13 engaged with the card slot 6 is fixedly connected to the protective shell 2 9, the wire body 1 is firmly fixed with the protective shell 14 and the protective shell 2 9 by a fixing member, and an elastic rubber gasket protrudes from the part where the arc groove 15 and the arc groove 2 10 are fitted with the outer wall of the wire body 1. Therefore, when the wire body 1 is fitted with the arc groove 15 and the arc groove 2 10, it will not be easily damaged. The part where the card block 13 is engaged with the card slot 6 is protruded with an anti-slip rubber ring. As a result, the card block 13 is more tightly engaged with the card slot 6, so that the protective shell 14 and the protective shell 2 9 will not be easily separated. The wire body 1 is provided with a slide groove 1 2 and a slide groove 2 3, the protective shell 1 4 is fixedly connected with a slider 1 8 slidably connected to the slide groove 1 2, and the protective shell 2 9 is fixedly connected with a slider 2 11 slidably connected to the slide groove 2 3. Therefore, after the protective shell 1 4 and the protective shell 2 9 surround the wire body 1, the protective shell 1 4 and the protective shell 2 9 can maintain their own positions stable, and the protective shell 1 4 and the protective shell 2 9 will not rotate on the wire body 1 even if they are subjected to external forces. Example

[0024] The technical solution is basically the same as that of the first embodiment, except that Figure 3 As shown, the fixing member includes a notch 17 and a notch 2 14 respectively provided on the protective shell 1 4 and the protective shell 2 9, and an elastic clamp 15 is provided at the notch 1 7 and the notch 2 14, and a screw 17 is passed through the elastic clamp 15, and the screw 17 is connected to a screw sleeve 18 by a thread. Under the action of the screw sleeve 18, the elastic clamp 15 can be deformed to clamp the protective shell 1 4 and the protective shell 2 9. A protrusion 16 is fixedly connected to the elastic clamp 15, and a transverse groove 12 is provided on the protective shell 2 9 to fit with the protrusion 16. Therefore, the elastic clamp 15 can maintain its own position, and the elastic clamp 15 will not rotate on the wire body 1.

[0025] In summary, the area on the wire body 1 that needs additional protection is determined in this embodiment, and then the protective shell 1 4 and the protective shell 2 9 can surround the designated area on the wire body 1. The slider 1 8 fits with the slide groove 1 2, the slider 2 11 fits with the slide groove 2 3, and the block 13 on the protective shell 2 9 fits with the slot 6 opened on the protective shell 1 4. Then the elastic clamp 15 can be put on the notch 1 7 and the notch 2 14, the screw 17 is used to penetrate the elastic clamp 15, and the screw sleeve 18 is respectively connected to the two ends of the screw 17 by threads, so that the elastic clamp 15 presses the protective shell 1 4 and the protective shell 2 9 tightly, and at this time, the protective shell 1 4 and the protective shell 2 9 surround the wire body 1.

[0026] The above description of the embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
