[0019] The lifting rope is connected to an external hoist. The clamping frame is placed outside the pole body. Rotate the adjusting rod to move the limiting frame outward. The outward movement of the limiting frame drives the connecting frame to move downward by squeezing the connecting roller. During the downward movement of the connecting frame, the clamping frame is driven by the adjusting rod to move inward, so that the clamping frame clamps and fixes the pole body, facilitating subsequent lifting. When placing the pole body, rotate the adjusting rod to move the limiting frame inward, separate the limiting frame from the connecting frame, and the connecting frame is reset upward through the spring, so that the connecting frame moves upward. The upward movement of the connecting frame drives the clamping frame to move outward through the connecting rod, so that the clamping frame is separated from the pole body.
