Furthermore, the clamping device is provided with a steel rod sleeve and a steel rod, the outer side of the steel rod sleeve is rigidly connected with the steel wire rope, and the steel rod is sleeved in the steel rod sleeve.

Furthermore, the lower end of the steel rod is a tip with an inclined surface at the outer side, and sawteeth are welded on the inner side of the tip.

The utility model discloses a steel pole penetrates to road inside through most advanced convenience, can carry out the block through the sawtooth to the core appearance and fix, prevents to drop when taking out.

Furthermore, the upper part of the built-in rod is a threaded column matched with the sleeve, and the lower end of the threaded column is welded with a T-shaped rod.

the utility model discloses a built-in pole lower extreme is T shape pole, can be convenient taking out the back, releases core appearance downwards.
