2．排線方式比較：根據收線時電源線的排布方式，可將收線裝置分為單圈和多圈兩種，現將其特點比較如下表排線方式單圈多圈典型樣機TSK-736SANYOA-R82(W)PANASONICNI-45GX排線規律較規則隨機排列，每次都不同層次不分明，較不規則摩擦阻力只有上下圈之間的摩擦，阻力小，拉收線時較順暢除上下圈之間的摩擦外，左右及傾斜方向會產生擠壓和斜嵌，磨損嚴重，拉收線時較不順暢佔用空間（相同電源線長度下）徑向佔用空間大軸向佔用空間小軸向佔用空間大徑向佔用空間小*收線控制依靠再次拉動電源線帶動棘輪轉離卡點，使轉軸回轉依靠按鈕動作打開轉軸卡點使其回轉*限速機構—般有—般無i•收線控制機構的方式與限速機構的有無，是在樣機拆解的基礎上的總結，並非絕對。我們就曾作過在7302單圈卷線機構上加按鈕控制，及在7861卷線機構中取消按鈕而採用拉動電源線收線的嘗試，但未經量產的驗證。ii•收線控制機構與限速機構的方式將于下具體闡述iii•在多圈收線機構中未見到限速機構的一個可能原因為，多圈收線需要達到一定的速度，以克服更大的收線阻力。我們發現，當速度較慢時，線的分佈會嚴重不均勻而沿一圈迅速爬高，容易卡死。
