[0009] Preferably, the arc-shaped hook-shaped main body of the hook-shaped tightening frame cooperates with the U-shaped groove structure to form a clamping space for the stirrup cables.

[0010] Preferably, the insulators are made of high-density polyethylene and are distributed in fin-like intervals.

[0011] The utility model has the following beneficial effects: the utility model sets a diamond-shaped bracket body to fix the spacing and positional relationship between the insulator and the conductor, and adds an anti-slip buckle, wherein the clamping handle and ratchet are used to prevent the wire from falling off and fixing the wire.
