A pivoting structure is provided to pivot together a first working block, a cutting blade, and a second working block of a pair of shears in such a manner that the cutting blade and the second working block work against each other to effect the scissors action. The pivoting structure includes a first locating slot disposed in the first working block, a pivot located in the first locating slot, a second locating slot disposed in the second working block, and a nut engaged with the pivot and located in the second locating slot.
