摘要
<p>The device has a spiral spring adjustable with rocker mechanics. A flexible cylinder (5) is inserted into the spiral spring (3), which fills out the interior of the spiral spring resting against the spring coils up to a height of approximately 2 to 3 mm. The flexible cylinder possesses a pre-determined flexibility. The flexibility of the flexible cylinder decreases over its length according to a given function.</p>
