The invention relates to a loop bar for high-place operation. The loop bar for high-place operation comprises an inner tube, a middle tube and an outer tube, wherein the inner tube is sleeved with the middle tube, the middle tube is sleeved with the outer tube, and the outer surface of the inner tube, the outer surface of the middle tube and the outer surface of the outer tube are each provided with an arc surface suitable for being gripped by an operator. The loop bar for high-place operation has the advantages that through the arrangement of the arc surfaces, the bar can be gripped by the operator advantageously, and the situation that the bar bends and shakes under the action of loads is avoided; and compared with an existing bar with the circular section, the inner tube and the middle tube can be effectively prevented from rotating when telescoping during operation, the operator can perform high-place operation easily, and the safety performance is improved.
