POSITIONING BOARD OF CHUCK |
| 摘要 |
A positioning board for a chuck includes a board member with a central bore, positioning bores and positioning slots. Each positioning slot has a main slot and two sub-slots connected to opposite ends of the main slot to form an H-shaped slot. Two flexible tongues are formed at opposite sides of the main slot. Therefore, while a post of a base engages the positioning slot, the flexible tongues are bent by the post to provide a precise engagement of chuck's bases. |
