Column and the 4th column, the 3rd column are fixed with the bridge arm.By so setting, conveniently dismounting can compress
Block, and compact heap stress acted on the contact surface of whole 3rd cylinder and compact heap, effect is preferable.
Beneficial effect:Due to using above technical scheme, the following effect that the utility model gets up, one, the design knot
Structure is simple, only carries out compression action, convenient use, while the setting for passing through tray, it is to avoid auto parts and components by rocker structure
Directly being contacted with workbench causes machinable position to be reduced, and simultaneously by cylinder as the offer power source of thrust, determines
Position effect preferably, and can just realize that two compact heaps of an air cylinder driven are acted by a structure for bridge arm so that one
Cylinder can drive two compact heaps to act, and perform the work of two compressions, more facilitate, while Stability Analysis of Structures.
