[0001] The utility model belongs to the technical field of electric tools, in particular to a convenient street code tightener. Background Art
[0002] Street tie, as an indispensable part of the cable laying process, is mainly used to straighten and fix the cable. The traditional street tie design usually includes a hardware bracket that can be nailed to the wall (consisting of a base and a bracket, which are used to fix the wall and the iron bar respectively), a porcelain bottle supporting the cable, and an iron bar connecting the porcelain bottle and the hardware bracket. In actual use, the cable will pass through the porcelain bottle and be tied and fixed to the porcelain bottle by winding metal wire. However, this traditional street tie has some problems.
[0003] Specifically, existing street code devices have significant defects in cable bundling. On the one hand, there is no unified standard for the bundling method and tightness, and there is a lot of arbitrariness in actual operation, which can easily lead to the cable being not firmly fixed, and it is easy to loosen or even come off after long-term use. On the other hand, the metal wire is directly wrapped around the cable sheath, which may not only damage the cable sheath, but also cause dangerous situations such as cable overheating, leakage, and even short circuit. These problems highlight the shortcomings of traditional street codes in cable fixing, which urgently need to be improved and optimized.
