Chain pipe tube clamp . It contains clamp handle and hinged at one end and  hydraulic tube fittings handle chain, has a front tooth with pliers handle tube clamp engagement. Further, the chain link plate and through the tube clamp handle is hinged at one end that is one end of the chain links of the hinge plate, the coupling plate and the clamp handle and the other end is hinged. The clamp handle front teeth showed a circular distribution. Pipe clamp the chain during operation, the non-hinged end of the chain is free, does not clamp handle fixed or hinged gripping the tube, by the friction of the rotating member and the tube which is wound between a chain to hydraulic machine , and by the engaging force of the torsion partial cone clamp handle and the distal end of the chain is generated in the pipe tube clamp handle biasing point of no surface. Therefore, the utility model of the chain-type pipe wrench to overcome the shortcomings of the existing chain-type pipe clamp, not only on the metal fittings, but also on the ceramic tube, thin-walled pipe, plastic pipe fittings and so gripping, rotating, does not produce bite marks, no damage to the pipe surface.
