Hammer capable of screwing nut

The utility model relates to the technical field of constructional engineering, in particular to a hammer capable of screwing a nut, which comprises a claw-type hammer head and a hammer handle, one end of the hammer handle is fixedly connected onto the side wall of the claw-type hammer head, and a silica gel protective sleeve is sleeved on the hammer handle. The nut positioning plate corresponds to the hexagonal nut positioning holes in the nut positioning plate, after the corresponding hexagonal positioning holes are found, the butterfly positioning bolt is rotated reversely, one end of the butterfly positioning bolt is screwed into the locking hole to be locked, otherwise, the nut positioning plate is retracted to the hammer handle through operation, or the nut positioning plate corresponds to the hexagonal nut positioning holes in the left side wall and the right side wall of the claw type hammer head in size. When a to-be-rotated nut is correspondingly sleeved with the corresponding hexagonal positioning
