Pipe joint buckling clamp

The utility model provides a pipe joint buckling clamp, and belongs to the technical field of machinery. The problem that an existing pipe joint buckling and pressing clamp is low in yield is solved. The pipe joint buckling clamp comprises a sliding sleeve, a mounting seat is arranged in the sliding sleeve, a plurality of sliding blocks are radially arranged at the outer end of the mounting seat in a penetrating manner, the inner end of each sliding block is provided with a buckling part communicated to a clamping hole, an elastic mechanism is arranged between the mounting seat and each sliding block, and the elastic mechanism provides elastic force to enable the outer end of each sliding block to keep the trend of protruding out of the outer wall of the mounting seat. The mounting seat is provided with a radial limiting part which is propped against each sliding block after each sliding block moves outwards in the radial direction, the outer end surface of each sliding block is in conical surface fit with th
