Zusammenfassung:	An arch frame grabbing mechanism, comprising two sets of clamping jaw assemblies (1), a supporting platform (2), and a driving unit (3). The two sets of clamping jaw assemblies (1) are arranged in the length direction of the supporting platform (2) and are used for clamping an arch frame (4) on the supporting platform (2); each clamping jaw assembly (1) comprises a connecting frame (11), a limiting block (12), and two oppositely arranged clamps (13); the connecting frame (11) is separately hingedly connected to the supporting platform (2), the driving unit (3), and the limiting block (12); two ends of the driving unit (3) are respectively hingedly connected to the connecting frames (11) of the two sets of clamping jaw assemblies (1). During extending and retracting, the driving unit (3) drives the connecting frames (11) to rotate around hinge points, so as to drive the limiting blocks (12) to move. The clamps (13) are hingedly connected to the supporting platform (2) and are connected to the connecting frames
