The nut spinner is designed for mechanised and automated assembly of threaded joints in electrical and mechanical engineering. It allows to follow various location schemes for the spinned spindle heads upon enhanced reliability, simple design and control. The multispindle nut spinner contains a body and statically spun spindle heads, each of which is built of mechanically connected - coaxially and consecutively - pneumatic motor and a mechanical gear, connected to a spindle (24) through a preventive cog coupling (5) and an OFF mechanism (8). The mechanism (8) consists of a safety valve (10) and a pneumatic cylinder (9). The cylinder's piston frontally affixes a driven semi-connector (7), attached to the guiding semi-connector (6) of the safety cog connector (5) with the outgoing shaft (4) of the transmission gear. The pneumatic cylinder (9) consists of a body shaped as a cylindrical sleeve (11) with peripheral slanted orifices (12), fitted in a support body (13) to a second element through connecting orifices (21 and 14). The driven semi-connector (7) leans onto a spring (22) with a regulable strain so that it forms a work chamber (17), connected to the control chamber of the safety valve (10).
