An improved strain difference loop of a hot continuous finish rolling mill belongs to the technical field of rolling mills and aims to solve the following problems in the conventional strain difference loop: an adjusting sleeve is difficult to dismount, zero calibration is not accurate, and the cable of a pressure sensor is liable to be damaged. The improved strain difference loop adopts the technical scheme that the outer wall of an adjusting sleeve is in clearance fit with the inner hole of a bracket; an external hexagonal bolt penetrates through a through hole of the bracket and a screw hole on the end surface of the adjusting sleeve to connect the bracket with the adjusting sleeve; a sealing gasket is arranged between the contact surfaces of the external hexagonal bolt and the bracket; an O type seal ring is mounted in a circumferential groove of the adjusting sleeve; and an adjustable zero calibration cushion block and a cable protection device are additionally arranged in the improved strain difference
