The invention provides a pipe holding clamp and a continuous pipe feeding device. The pipe holding clamp comprises a housing and a plurality of clamping blocks; the multiple clamping blocks are distributed in the circumferential direction to form a circular sleeve; inclined wedge surfaces are arranged at the parts, close to the two ends of the circular sleeve, of the clamping blocks; the inclinedwedge surfaces are located on the outer sides of the circular sleeve and are arranged in the axis direction of the circular sleeve; guard rings are correspondingly arranged at the two ends of the clamping blocks; clamping rings are arranged on one sides, close to the clamping blocks, of the guard rings; the direction of the clamping rings is perpendicular to the axis direction; corresponding clamping grooves corresponding to the clamping rings are formed in the clamping blocks; the guard rings are further connected with a telescopic oil cylinder moving in the axis direction; the telescopic oilcylinder is further conne
