Space reconfigurable truss type capturing mechanism and capturing method thereof

The invention provides a space reconfigurable truss type capturing mechanism and a capturing method thereof.The space reconfigurable truss type capturing mechanism comprises a base and two reconfigurable truss type capturing fingers, and each reconfigurable truss type capturing finger comprises a butt joint plug truss unit, a butt joint connector truss unit, a plurality of modular extensible trussunits and a plurality of linear driving devices; the butt joint plug truss unit, the modular extensible truss units and the butt joint connector truss unit of each reconfigurable truss type capturingfinger are connected in sequence, and a linear driving device is connected between every two adjacent truss units of each reconfigurable truss type capturing finger. Butt joint or separation betweenthe capture fingers and the base and butt joint or separation between the two fingers can be achieved, and capture can be completed by selecting a two-finger cooperation mode or a mode that the two fingers are in butt joint to
