The hook claw body 4 penetrates through the through hole close to the outer side of the seven-hole annular iron plate two 2. The end of the hook claw body 4 is welded with the flexible ball head 5. The upper end of the hook claw body 4 penetrates through the through hole close to the outer side of the seven-hole annular iron plate one 3.

[0031] Further, the heavy hammer steel cable 6 penetrates through the through holes located in the middle of the seven-hole annular iron plate one 3 and the seven-hole annular iron plate two 2. The upper end of the heavy hammer steel cable 6 is knotted. The in-barrel lead hammer 7 is located in the barrel of the anchoring steel sleeve barrel 1 and is installed at the end of the heavy hammer steel cable 6. The bottom of the anchoring steel sleeve barrel 1 is provided with a concrete-breaking lead hammer 8.

[0032] Further, the end of the locking sleeve 9 is knotted and tightly sleeved on the top hook-shaped part of the plurality of hook claw bodies 4. The plurality of catching chains 10 are annularly distributed and installed on the reinforcing hoops of the reinforcement cage. The anti-floating sleeve ring 11 is connected to the end of the catching chain 10.

[0033] Specifically, one end of the catching chain 10 is connected to the bottom reinforcing hoop of the reinforcement cage. The other end of the catching chain 10 is connected to the anti-floating sleeve ring. When assembling the movable catching structure, the hook claw body 4 is sequentially penetrated through the through holes close to the outer side of the seven-hole annular iron plate one 3 and the seven-hole annular iron plate two 2. The flexible ball head 5 is welded at the end thereof.
