Title:
スクリュードライバビットを含む工具用のチャック
Document Type and Number:
Japanese Patent JP4264349
Kind Code:
B2
Abstract:
A chuck ( 1 ) for tools, especially screwdriver bits with a polygonal section ( 2 ), has a polygonal cavity (3) for the insertion of the polygonal section ( 2 ). A wall ( 4 ) of the polygonal cavity ( 3 ) has a window ( 5 ) in which is disposed a pressure-piece ( 6 ) which can be displaced in the insertion direction (E) and which, in order to secure the inserted polygonal section ( 2 ) against being drawn out, is forced against the polygonal section ( 2 ), in a direction transverse to the insertion direction (E), by a sloping inner wall ( 9 ) of an actuating element. The actuating element is outside the window and is retained in a clamping position by a restoring spring ( 10 ), and, in a release position of the actuating element ( 7 ), moves aside out of the polygonal cavity ( 3 ) in order for the polygonal section ( 2 ) to be drawn out. The pressure-piece ( 6 ) is subjected to the action of a compression spring ( 8 ) acting counter to the insertion direction (E) and, upon displacement counter to the direction of spring action, moves aside out of the polygonal cavity ( 3 ).
