Zero point positioning device and zero point positioning kit

The invention relates to a zero-point positioning device and a zero-point positioning kit. The zero-point positioning device comprises a base, wherein the base is provided with a mounting space which extends along a first direction and is provided with an opening at one end; a clamping groove is formed in the blind rivet, and the blind rivet can extend into the mounting space through the opening; the pull claw is mounted in the mounting space; the pull claw comprises a main body and a plurality of clamping petals, and the main body is slidably connected with the base in the first direction; the multiple clamping petals are circularly distributed at intervals, and one ends of the clamping petals are fixedly connected to the side, facing the opening, of the main body; as the main body gradually gets away from the opening, the clamping petals abut against the base, elastically deform and gather together to extend into the clamping groove so as to abut against the blind rivet in the first direction; and as the ma
