The continuous oil pipe clamp mechanism includes a saddle-shaped clamp block and a clamp block seat. The saddle-shaped clamp block is buckled on the clamp block seat. The saddle-shaped clamp block includes a saddle-shaped clamp portion and a bottom, wherein the bottom has a clamp groove, and tongue platforms are arranged at two ends of the clamp groove. The clamp block seat includes a fit portion fitted to the saddle-shaped clamp block, wherein the fit portion is provided with a sunk groove matched with the clamp groove and pairs of bosses. Grooves matched with the tongue platforms are formed between the pairs of bosses. The clamp groove is buckled in the sunk groove, and the tongue platforms are arranged in the grooves and are limited by stop pins. The mechanism facilitates replacement of the clamp block, enabling an injection head to be stable in continuous work and convenient to maintain.
