Zero point positioning device and zero point positioning kit

The utility model relates to a zero-point positioning device and a zero-point positioning kit. According to the zero point positioning device, a guide-in hole is formed in a base, and a mounting space communicating with the guide-in hole is formed in the base; the blind rivet can extend into the mounting space through the lead-in hole; the pull claw is mounted in the mounting space; the pull claw comprises a main body and a plurality of clamping petals, the clamping petals are circularly distributed at intervals, and one ends of the clamping petals are fixedly connected to the side, facing the guide-in hole, of the main body; when the main body gradually gets close to the leading-in hole, the multiple clamping flaps abut against the base and elastically deform to gather together to hold the blind rivet, and when the main body gradually gets away from the leading-in hole, the multiple clamping flaps elastically reset to get away from each other to loosen the blind rivet, and therefore only the matching structu
