Abstract
Tin snips includes two cutting blades intersecting each other for cutting and two handles for activating the cutting of the two cutting blades. A safety device is disposed in the tin snips for preventing the two cutting blades from opening. The safety device includes a protrusion extending from an edge of one of the handles, a recess provided in an edge of the handle having the protrusion, and a buckling element connected to the other of the handles. The buckling element includes two movable portions rotatable to cover a position where the two handles are drawn to a closed position, an engaging portion disposed between the two movable portions to cross the protrusion to engage into the recess when the movable portions rotate, and a restricting portion connected between the two movable portions and the engaging portion.
