Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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

[0025] like Figure 1 As shown;

[0026] A protective sleeve for electric wires and cables comprises a left sleeve 1 and a right sleeve 2.

[0027] In this implementation scheme: after checking the public (announcement) number CN 213385637 U, a protective sleeve for electric wires and cables is found. For details, please refer to the disclosed technology below; in order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "although the design realizes the function of cable protection, in actual use, since the upper protective sleeve and the lower protective sleeve are screwed and fixed by bolts, first of all, the installation is inconvenient, and secondly, after long-term use, the bolts are corroded and rusted, and the later maintenance operations are relatively inconvenient." Combined with actual use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve this technical problem, a disassembly and assembly component 3 is added on this basis.
