The above technical problem of the present invention is mainly a pipe tensioner solved by the following technical solution, characterized in that it includes a bracket, a baffle plate and a tensioning mechanism set on the bracket for adjusting the tightness of the rope, the end of the bracket and the baffle plate are provided with grooves matching the edges of the floor, and one end of the rope is fixedly connected and the other end is fixed to the rotating shaft assembly in the tensioning mechanism. When it is necessary to tighten the combined floor, the baffles are provided on both sides of the floor and the floor can be easily tightened using the tensioning mechanism for adjusting the tightness of the rope, and the floor tensioner is more effective than and comparable to manual operation. Some existing professional tools. It is simpler and cheaper.
