The invention provides a pulling connecting device and a production line. The pulling connecting device comprises a first fixing seat (10), a second fixing seat (20) and a buffer device. The first fixing seat (10) is used for being connected with a pulled device; the second fixing seat (20) is used for being connected with a pulling device; two ends of the buffer device are respectively connected with the first fixing seat (10) and the second fixing seat (20), the buffer device comprises a sliding sleeve buffer mechanism, and the sliding sleeve buffer mechanism is used for buffering movement impact on the first fixing seat (10) along a first direction and buffering rotation impact around a rotation axis which is the first direction. The pulling connecting device and the production line have the advantages that the pulling connecting device is arranged between the pulling device and the pulled device, the sliding sleeve buffer mechanism in the pulling connecting device can relatively move and rotate when the pulled device is impacted when the pulled device is pulled by the pulling device, accordingly, influence of the impact on the pulling device can be relieved, abnormal stress conditions of the pulling device can be changed, the service life of the pulling device can be prolonged, and the cost can be saved.
