| 摘要 |
<p>The invention relates to a small key-holder plate including three small-plate parts (1, 2, 3) connected by a swivel pin (5) permitting their rotation. These small-plate parts (1, 2, 3) have rails (9, 10) at their periphery which make it possible rapidly to fit and remove the key-holder rings (4) including heads of spherical shape sliding in the said rails (9, 10), by means of rotation of the small-plate parts (1, 2, 3) around the swivel pin (5). A spring (6) for locating the small-plate parts (1, 2, 3) is provided in a through hole (17) in the central part (2). This spring (6) carries balls (7) interacting with locating cavities (8) provided on the opposite faces of the left and right small-plate parts (1, 3). <IMAGE></p> |
