The cable ties have been widely for bundling articles in Christmas gift factories, electronics factories, wire processing factories, wires and cables, toy factories, festive festivals, stationery stores, fresh food supermarkets, residential daily necessities, electrical appliances and connectors. The cable tie usually includes a tie body and a locking head, the locking head has an elastic sheet, the elastic sheet is provided with locking teeth, and a row of teeth are integrally formed on an outer wall of one side of the tie body.

Compared with the prior art, the present invention has the following beneficial effects:

When the tie body penetrates through the locking head, the tie body is in contact with the locking teeth through the outer guide surface and the inner guide surface, and the inner guide surface is guided by the inclined surface to push the elastic block, so that the elastic block slides into the storage cavity, which is convenient for the tie body to pass through. After bundling, the elastic block pushes the tie body by the own elastic force, so that the movable teeth are engaged with the inner teeth. Meanwhile, the tie body is pushed by the elastic block to be close to the fixed teeth, and the fixed teeth are engaged with the convex teeth, so that two surfaces can be engaged and stressed. Stress on the two sides can reduce the stress of a single tooth, thereby avoiding tooth breakage. Engagement on the two sides can avoid the loosening of the teeth caused by the pulling of the tie body, thereby improving the bundling fastness.

The convex teeth and the inner teeth are uniformly distributed in a length direction of the tie body, the length of the outer platform is the same as that of the inner flat groove, the outer platform faces the inner flat groove, the outer guide surface overlaps with the inner stop surfaces on two sides of the inner platform and the tooth surface at the inner guide surface, and the outer flat groove overlaps with the tooth surface of the inner guide surface close to one end of the inner flat groove, so the convex teeth and the inner teeth in the length direction of the tie body are different from each other up and down, which are not complementary and are asymmetrical. Furthermore, the teeth on the two sides of the tie body partially overlap, so that the overall thickness of the tie body is uniform, thereby enhancing the strength of the overall tensile stress, preventing the tie body at the tooth spacing from being broken during bundling and bending, and improving the durability.

After bundling, the elastic blockpushes the tie bodyby the own elastic force, so that the movable teethare engaged with the inner teeth. Meanwhile, the tie bodyis pushed by the elastic blockto be close to the fixed teeth, and the fixed teethare engaged with the convex teeth, so that two surfaces can be engaged and stressed. Stress on the two sides can reduce the stress of a single tooth, thereby avoiding tooth breakage. Engagement on the two sides can avoid the loosening of the teeth caused by the pulling of the tie body, thereby improving the bundling fastness.

Further, the thickness of the extend-out headis less than that of the tie body, one end of the extend-out headaway from the tie bodyis of a triangular structure, and a plurality of anti-slip stripsare fixedly arranged on an outer wall of the extend-out head.
