A way to change how stiff a fidget feels, often by tightening a screw against a spring-loaded ball.
What it is
Adjustable resistance lets you change the force needed to move a coin or slider. A common design uses a set screw that compresses a spring behind a detent ball; others swap springs or magnets.
Why it matters
It lets one fidget suit different moods or settings. Do not over-tighten: too much preload can wear the track or seat the ball too hard.
Also known as: Tension Adjustment, Adjustable Detent, 可调阻力.
是什么
弹珠调阻可以改变转动响币或推动推牌所需的力。常见做法是用顶丝压缩顶珠后面的弹簧，也有换弹簧或换磁铁的设计。
为什么重要
同一件玩具可以适应不同心情和场合。不要拧得太紧，预压过大可能磨损轨道或让钢珠卡得太死。
又称：Tension Adjustment、Adjustable Detent、可调阻力。
