The specific embodiment
From Fig. 1, Fig. 2, Fig. 4 as can be known, quick binder and the retaining mechanism of hydraulic combined punching ﹠ shearing machine plate cutting of the present invention, it comprises shear pressing plate 4, lead 12, eccentric wheel 3, support column 2, locking nut 5, locking plate 6, fixed disk 7; The external diameter of eccentric wheel 3 is divided into three sections, and two sections are eccentric structure about it, and left section is touched with the up and down edge joint in shear pressing plate 4 central square holes, and the stage casing thread bush has locking nut 5, and right section is matched with the locking plate 6 of inner eccentric holes; Left section of support column 2 affixed with the right wallboard of fuselage 1, and the right section endoporus with eccentric wheel 3 matches; Fixed disk 7 is fastened on the right-hand member of support column 2 by bolt 8, spring washer 9; Locking plate 6 is pressed on the fixed disk 7 by locking nut 5; Be processed with to shear pressing plate 4 bilateral symmetry kidney slot; Left section of lead 12 affixed with the right wallboard of fuselage 1, and the stage casing is dug flat part cunning and is contained in the kidney slot of shear pressing plate 4, and thrust snap bolt 13 is housed in the right-hand member screw.
