Document Type and Number:
Japanese Patent JP3730866
Kind Code:
B2
Abstract:
An automatic screw clamping device of automatically tightening bolts fitted in a metallic mount member which is hard to nail comprises a casing (2), a rotator (4) disposed in said casing (2) in a manner that said rotator may rotate and move up and down, a biasing member (5) connected with the rotator (4) and the casing (2), and a covering member of covering over the casing (2). There are provided fitments on the lower end of the casing (2). The rotator (4) has on its inner periphery an engaging portion (41) that can unrotatably mesh with the clamped member (n), and on its outer periphery a locking portion (42) which is unrotatably lockable to the casing (2). The rotator (4) locked to the casing (2) is engaged with the clamped member (n) to press the casing (2) downward. This may cause the casing (2) to be detached from the rotator (4), then the casing (2) gets turning and the fitments (71) enter into the corresponding fitment-receptive portions (82) of washer member (8) disposed beneath the clamped member (n) until the casing (2) is fixed to the washer member (8), whereby the rotator (4) can be maintained in a position where the clamped member (n) is biased in a direction in which it runs for being tightened.
