This research is a kind of connecting device between connecting bars and chains. In order to prevent the connection port and fixed port from signing and unlocking each other, they can not penetrate through the through hole, It needs a lot of processing and assembly time, assembly state is sharp and so on, so it is not safe.;In this study, a fixed slot (3) is formed at the connecting port (1), a sloping surface (7) of the inserting part (8) is formed in the inserting piece (6), and a fixed stone column (10) is formed at the fixed port (10) on the hanging ring plate (12), on which a socket (6) and a connecting port (1) are placed, which are assembled by pressing a bed or striking operation at one time Dog chain and dog chain distance connection device.
