Abstract: A screw clamping device includes a body, a pressing unit, a resilient unit, a clamping unit and a connecting unit. The body is a hollow-core cylinder, is subject to axial penetration of a screwdriver, and is movable axially in synchrony with rotation of the screwdriver. The pressing unit is disposed on the body and adapted to press against a surface of a working object. The resilient unit is disposed between the body and the pressing unit. The clamping unit is rotatably connected to the body. The connecting unit has one end connected to the pressing unit and the other end connected to the clamping unit. While the body is moving axially, the connecting unit drives the clamping unit to rotate and thereby clamp or loosen screws.
