Magnetic arc-jaw tongs

The invention belongs to the technical field of hand tools, and relates to magnetic arc-jaw tongs. The magnetic arc-jaw tongs are formed by hinging of a left half 1 and a right half 7 via a tong shaft 3. The left half 1 is composed of a left tong handle 2 and a left tong head 4 as a whole, and the right half 7 is composed of a right tong handle 8 and a left tong head 9 as a whole. Each of the left tong head 4 and the right tong head 9 is provided with an arc jaw 6. Magnetic stripes 5 are arranged at positions, close to the arc jaws 6, on the left tong head 4 and the right tong head 9. The arc jaws 6 can reliably clamp screws with various screw heads, matched washers penetratingly arranged on the screws can be attracted via magnetic attraction force, and the screws are mounted, dismounted, picked and placed at deep recesses reliably and efficiently. The magnetic arc-jaw tongs are used for reliably placing the screws in the deep recesses accurately and reliably as well as taking out the screws together with the
