Zusammenfassung:The utility model discloses an electrical conduit convenient for threading, and belongs to the technical field of electrical conduits. The sleeve comprises a sleeve body, the sleeve body is in a circular tube shape, a set of grooves are formed in the inner wall of the sleeve body, a contact protrusion facilitating threading is formed between every two adjacent grooves, and the outer wall of the sleeve body is a smooth surface; the whole groove is of a spiral structure; the groove is an arc-shaped groove; the grooves are formed in the axial direction of the sleeve body. According to the utility model, the inner wall structure of the electrical conduit is improved, and the surface-to-surface friction between the wire and the conduit in the original threading process is changed into the surface-to-point friction between the contact bulges on the inner wall of the wire and the conduit in the threading process, so that the stress points in the threading process are reduced, the friction force in the wire drawing p
