アウトリングを嵌合してなる伸縮ポール。 A cylinder partition is used in a telescoping pole that sequentially unwinds multiple pipes of a predetermined length into a multi-stage cylinder shape by injecting pressurized air into the largest diameter pipe, which becomes the lowest sheath tube, by sequentially reducing the diameter and fitting the shafts. In the longitudinal direction of the outer periphery of the lower part of the annular concave part for preventing removal formed at the top of each pipe except for the smallest diameter pipe with a partition lid, the bulging stopper stepped part faces into the pipe through the extraction window when rotated by its own weight. An automatic locking body equipped with a locking nail is provided, and the lower end of a lock nail release piece protruding from the lower part of the automatic locking body can freely come into contact with a support collar stepped portion at the upper end of the next stage pipe to be externally fitted, A sliding packing that slides into contact with the inner wall of the next stage pipe to be externally fitted is fitted to the lower end of each pipe except the largest diameter pipe, and the sliding packing of each pipe except the largest diameter pipe and the smallest diameter pipe is fitted. An annular convex part for a stopper is formed on the upper part to ride on and lock onto the lock nail of the next stage pipe which will be externally fitted, and an air injection valve is installed near the bottom cover of the largest diameter pipe, and an air injection valve is attached to the outer periphery of the largest diameter pipe. A telescopic pole made by fitting a lockout ring for an automatic locking body.
