PURPOSE: A pipe connecting device is provided to enable a pressing block to be easily coupled/disassembled by simple disassembling of a coupling pin if the pressing block is damaged. CONSTITUTION: A pipe connecting device(900) comprises a gemeled type of left and right nippers(100,100'), a compression spring(120), a connecting frame(200), a gemeled type of block coupling pieces(400) and four pressing blocks(500). The compressed spring is inserted into the center of the left and right nippers and applies compression force. The connecting frame makes tight contact with the top and the bottom of the left and right nippers. The connecting frame is coupled to a fixed pin by a fastening ring. The block coupling pieces make tight contact with a ⊂-shape groove of each head of the left and right nippers. The pressing blocks are coupled to the block coupling pieces and press a pipe. |
