The invention relates to an escalator hand strap adjusting device, and belongs to the technical field of escalators. The escalator hand strap adjusting device comprises a hand strap. The hand strap is located between an upper boom and a lower boom of an escalator truss. The adjusting device comprises an adjusting screw, a tensioning wheel, a hanging ring and a support. The support is formed by placing a clamping block between two parallel plates and fixedly connecting the clamping block and the two parallel plates. The adjusting screw is fixedly arranged on the upper boom of the truss through a first angular piece. The tensioning wheel is fixedly connected in the support. The upper end of the tensioning wheel makes contact with the hand strap. The hanging ring is of a trapezoidal symmetrical bent structure, and wing plates are arranged on the bent positions on the two sides. The upper end of the hanging ring is connected with the adjusting screw through a bolt. The wing plates on the two sides of the hanging ring are fixedly connected to the two sides of the support through second angular pieces. By the adoption of the structure, the tensioning degree of the hand strap can be precisely and greatly adjusted, a guide device is arranged, good stability is achieved in the adjusting process, and interference in other components in the escalator can be avoided.
