The invention provides a connector with a quick replacing device. The connector comprises a fixed connector, a movable connector and a lock nut. An annular boss is arranged on the outer wall of the lock nut, the lock nut is sleeved with the fixed connector in a connected mode, and the fixed connector is clamped at one end of the annular boss. A cavity is formed in the fixed connector, and the movable connector stretches into the cavity and is locked at the other end of the annular boss of the lock nut. A first square groove is formed in one side of the fixed connector, and the movable connector is provided with a second square groove, wherein the first square groove is communicated with the second square groove. The connector is further provided with a connecting rod, the connecting rod penetrates through a channel formed by the two square grooves, one end of the connecting rod is connected with the first square groove through a first screw, and the other end of the connecting rod is connected with the second square groove through a second screw. An eccentric spanner is arranged at the joint of the connecting rod and the second square groove, an eccentric wheel of the eccentric spanner is hinged to the second screw, and the length difference of a long half shaft and a short half shaft of the eccentric wheel is equal to the width of a gap between the movable connector and the annular boss.
