Abstract

The utility model relates to a screw band, which comprises a sliver-shaped band body, and one upper surface of the band body extends downwards to form a plurality of fixing seats. The fixing seats are spaced with each other and orderly ranged, and can be used for the demountable penetration and fixing of a plurality of screws. The utility model is characterized in that each fixing seat is provided with a fixing wall which circles a central axis, and the internal diameter of the fixing wall is smaller than the external diameter of the screw. The fixing wall defines clamping space which penetrates through the band body, and a large amount of expanding and penetrating space are convexly extended from the clamping space outwards, and are communicated with the clamping space. When the screws are penetrated, the fixing seats are compressed to deform to enter the clamping space, and the fixing seats clamp and fix the screws. Simultaneously, the expanding and penetrating space can keep elasticity, which causes the expanding and penetrating space not to be broken and deformed when the screws are penetrated, and causes a plurality of screws to be penetrated and be fixed on the screw band. The screwing and locking work can be rapidly carried out.
