| 20120260505 | UTILITY KNIFE AVOIDING ACCIDENTAL DETACHMENT OF BLADE - The invention discloses a utility knife preventing its blade from accidental detachment. Prior utility knives may lose constraint on the blade due to tilting of the retaining member when the blade receives external force from the blade holder pulling outward, causing the blade to detach accidentally from the blade holder. In the present invention, the line of the action force in the engagement area of blade and retaining member extends over the axis of axle pin where the retaining member is mounted, so that when the blade receives external force pulling it outward from the blade holder, a counterclockwise torque is formed to the retaining member to allow the retaining member constrain the blade more tightly and thus prevent the blade from accidental detachment. | 10-18-2012 |
