Abstract
A utility knife includes a shell; a swingable lever pivoted to the shell and protrusive outside the shell; a blade carrier with a notch, slidably disposed in the shell; a linkage mechanism with linkages rotatably connected to one another, two of the linkages rotatably connected to the shell and the blade carrier, respectively; an elastic recovery mechanism connected with the blade carrier and the shell; and a safety member with a projection, movably disposed on the shell. When the projection is located within the notch, the blade carrier is blocked by the projection and non-movable relative to the shell. When the projection is located out of the notch and the linkage mechanism is driven by the swingable lever to push the blade carrier, the blade carrier is movable relative to the shell.
