The invention discloses a hollow nail and a matching nail remover. The hollow nail includes an outer nail and an inner nail arranged inside the outer nail. The outer nail has a tapered nail head, an outer thread The nail shank, the nail cap formed on the upper part of the nail shank, and the accommodation chamber for inserting the inner nail. The inner wall of the accommodation chamber is provided with a plurality of anti-rotation protrusions that cooperate with the protrusions to prevent rotation. An anti-rotation groove for inserting the raised strip is formed between them; a cross-shaped through groove is provided inside the inner nail, and the upper part of the cross-shaped through groove communicates with the upper end surface of the inner nail. Since the present invention sets the hollow nail as an inner and outer nail, the structure of the hollow nail is enhanced, and the hollow nail is prevented from being broken during the nail removal process; secondly, by setting a cross-shaped through groove in the inner nail, it is convenient to remove the inner nail from the inner nail after the nail is broken. The operation of taking out the outer nails is easy and convenient.
