[0002] A turnbuckle is a rigging used to bind and tighten steel wire ropes. It can tighten steel wire ropes and adjust the tightness. Existing turnbuckles generally have an independent threaded rod at each end, each threaded rod is equipped with a turnbuckle fork or hook, and the two threaded rods are connected by a connection frame with threaded holes at both ends. The connection frame is generally a hard metal part, but after being subjected to large tension and external corrosion for a long time, the internal threads are prone to wear, corrosion and thread slippage.

[0003] The utility model with the application number 202122530639.9 was searched and provided with a turnbuckle screw for hoisting in industrial production. The utility model provides a fixing hole on the connection frame, and fixes the clamp seat in the connection frame through a threaded column, and provides a threaded hole in the center, through which the screw is connected. The screw passes through the connection frame and is connected to a turnbuckle fork to connect a wire rope or a hook. The clamp seat of this application is fixed to the fixing hole by a threaded column, and there are multiple fixing holes on the entire connection frame. When the clamp seat is subjected to force, the threaded column will be subjected to lateral tension, which is more likely to cause the fixing hole to slip, and the damaged fixing hole is unevenly stressed, which is easy to cause the connection frame to crack or even break.
