CONSTITUTION: A tightening bolt restoration apparatus(A) for a support clamp comprises a rotary pressing part(40). The rotary pressing part horizontally reciprocates on the top of a backing part(20) fixed to a support frame(10) using first and second guiders(30,30'). The rotary pressing part has a nut coupler(42). The nut coupler has a rotary shaft(41). The rotary shaft penetrates through the first and second guiders. A hydraulic motor(43) is coupled to one end of the rotary shaft, and a hexagonal hole(421) is formed in the other end of the rotary shaft. A guider shaft(44) parallel to the rotary shaft is coupled to the front of the first guider. |
