摘要

Disclosed are a screw-supporting device (2) and a screwing tool (1). The screw-supporting device (2) is used to assist the screwing tool (1) to locate a screw, the screwing tool (1) has an output shaft axis, with the screw-supporting device (2) comprising a housing (6), an abutting mechanism (7) for abutting against the screw along the direction of the output shaft axis via a screw bit (703), a driving mechanism provided in the housing (6), and a supporting mechanism for supporting a screw; the abutting mechanism (7) makes a movement upon abutting against the screw via the screw bit (703), and the driving mechanism drives the supporting mechanism to move to the position for supporting the screw in response to the movement of the abutting mechanism (7). The screwing tool (1) comprises a screw-supporting device (2) which supports a screw in operation. The screw-supporting device (2) can support a screw automatically.
