DESCRIPTION OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a chain, and more particularly to the design of a joint tab in the chain. [Prior Art] At present, the conventional transmission chain is mainly composed of a plurality of π, a sigma key piece and a chain pin connected in a long strip shape, and then a group includes: a joint of the joint piece and a chain pin to the chain The ends are connected to form a ring shape, which can be applied between the sprocket wheels as a transmission. "In the foregoing, as shown in the sixth figure, the pin tabs (41) of the chevron shape are respectively provided at both ends of the joint tab (4〇), whereby the seventh and eighth figures do not The two connector tabs (40) abut against the inner key plates at both ends of the key bar (the 2 0 mountain "b side" is a chain pin (3 〇) respectively from the pin hole (...the large hole 钿 (4 1 1) After the end of the chain pin from the pin hole (4 1 ):: end (4 1 1) spear multi-directional to the small hole end (4 1 2), so that the chain pin (3:) end: the neck (33) placed at the small hole end (4 丄 2) of the keyhole (41), and assembled together. The quasi-monthly joint tab can provide a kind of bondable pin group connected to the key strip: end formation The member of the joint, however, the chain pin of the joint is provided in the chain pin group. The type of the chain is designed to be convex, and the chain is not in the tight end state. ^ Qian Weng (4) ^ convex shape rail W shift In the process of use, the joint tab and the chain pin are easy to loosen. [Inventive content] rs 4 1271481 The main purpose of this is to provide a chain Connector tab, Xiwei 2::: to improve the connector tab The disadvantages of the connection of the chain pin are not stable. The technical solution proposed by the present invention is that the joint end of the joint end is provided with a pin hole, and the joint piece has a pass. The hole is adjacent to or two pin holes, and the through hole and the adjacent pin can be bent into a strip-shaped fastening portion, so that after the chain lock is inserted, it is pushed into the groove of the chain pin neck ring,
