The two connecting rod assemblies 2 are respectively arranged at two sides of the detected tie bar 7. Each two-bar linkage assembly 2 comprises two U-shaped steel arms. The U-shaped steel arm comprises a web plate and two wing plates. The two wing plates are arranged on two sides of the web plate to jointly form a rod piece with a U-shaped cross section. The wing plates extend out of the connecting plates at two ends of the U-shaped steel arms. And bolt holes are formed in the connecting plate. The two U-shaped steel arms are hinged through a strap Kong Shuanding to form the two-bar linkage assembly 2.
