The upper part of the central vent hole of the second circular truncated cone block is a threaded section.

The center of the round platform block is provided with a threaded blind hole.

The sliding block exceeds the circumferential surface of the identification chain pin by 1-4mm after being positioned by the second positioning through hole.

When the structure is used, the th circular platform block pushes out the sliding block, the sliding block is positioned by the aid of the third positioning hole and the second positioning through hole through the bolts, the identification chain pin cannot jump, when the identification chain pin needs to be taken out, the bolts only need to be loosened, the th circular platform block is replaced by the second circular platform block, then the sliding block slides towards the axis to be attached to the lower circular platform of the second circular platform block through the vent holes by the aid of the vacuum pump, the sliding block is positioned by the aid of the third positioning hole and the th positioning through hole through the bolts, the identification chain pin is knocked, and the identification chain pin can be taken out.

The chain pin identification device has the beneficial effects that the design of the bosses at the two ends of the chain pin is identified, and the position shifting of the chain pin is prevented.
