In the above solution, specifically, the number of hooks and pressing grooves is two respectively, and each set of hooks and pressing grooves corresponds to a chain; the base is bound and fixed to the metal pipe by two chains.

During installation, one end of each chain hangs in the hook on the corresponding side of the base, and the other end passes through the metal pipe from the bottom of the base, and penetrates between the inner U-shaped groove of the corresponding side compression groove and the fixing bolt; then tighten it. The chain is in a tensioned state, and the locking bolt is moved downward by rotating the locking bolt, and the locking bolt and the fixing bolt lock the chain. When the tension of the chain needs to be fine-tuned, the position of the inner U-shaped groove can be adjusted up and down by screwing the adjusting nut. Finally, the magnetic drill is placed in the four locking devices on the base 1, and the side wall of the magnetic drill base is locked by rotating positioning bolts to fix the magnetic drill.

Beneficial effects: The device is suitable for drilling metal pipelines of various sizes and materials, and can also position the magnetic drill to prevent it from sliding on the surface of the pipeline, thereby effectively improving the drilling efficiency and quality.
