Large-range clamping hydraulic manipulator clamping mechanism

The invention relates to the technical field of die-casting manipulators, in particular to a large-range clamping hydraulic manipulator clamping mechanism which comprises a base, an air cylinder is mounted on the base, a moving block is mounted at the output end of the air cylinder, first connecting rods are movably connected to the upper end and the lower end of one side of the moving block, and second connecting rods are movably connected to the upper end and the lower end of the other side of the moving block. A first clamping hand is arranged between the two first connecting rods, a second clamping hand is arranged between the two second connecting rods, a plurality of first clamping pieces are arranged on the side, close to the second clamping hand, of the first clamping hand, and a plurality of second clamping pieces are arranged on the side, close to the first clamping hand, of the second clamping hand. The first clamping piece and the second clamping piece each comprise a connecting block and a clampi
