摘要： A tool, such as a tape measure, including a spring-based retraction system is shown. The spring-based retraction system includes at least two springs that drive a tape spool during tape retraction. The springs are indirectly coupled to each other via a single center post, in one embodiment, two center posts on a single spool, in another embodiment, or two center posts that are on different spools, in another embodiment.
