The utility model relates to the technical field of clamps, and particularly discloses a quick chuck which comprises a first clamping piece, a second clamping piece and an elastic restraining piece. The first clamping piece is detachably connected with the second clamping piece, the upper portion of the first clamping piece is rotationally connected with the upper portion of the second clamping piece, so that the lower portion of the first clamping piece is close to or away from the lower portion of the second clamping piece, and a clamping cavity used for installing a workpiece is defined by the first clamping piece and the second clamping piece. The elastic restraining piece is used for enabling the first clamping piece and the second clamping piece to be close to each other so as to clamp a workpiece; by means of the structure, small regular bodies of different shapes can be effectively clamped, and a fixed workpiece can be conveniently machined and welded; the workpieces are fast to mount and dismount, so
