Abstract

The utility model relates to a clamping tool used in the processing of precision parts, in particular to precision flat-nosed pliers capable of quickly moving a movable block and quickly clamping in one step. The precision flat-nosed pliers comprise a bottom plate, a sliding rail, a fixed block, the movable block, a drawbar and a fixture block, wherein the movable block is provided with a cavity with an opening facing the bottom; a drawbar via-hole is formed on the side wall in the shift-out direction; the drawbar via-hole is hinged with one end of the fixture block in the cavity; a fixture hole is formed on the other end of the fixture block and is clamped on the sliding rail; one of a hinge shaft hinged with the fixture block and the movable block is connected with the drawbar in a relative rotation manner, and the other one is connected with the drawbar through a screw; and the fixture block can incline to the force exertion direction of the drawbar when the drawbar rotates. When no force is exerted by the drawbar to the fixture block, the movable block can be pushed rapidly to keep contact with an object to be clamped; and the fixture hole of the fixture block is firmly clamped on the slide rail when the drawbar rotates, so that the larger the counterforce exerted by the clamped object to the movable block is, the more tightly the fixture block clamps.
