現今服裝上普遍使用到拉鏈，包括衣物的口袋、褲/裙頭的開口或是外套的兩門襟等處，然而只要是有內裡的服裝，當拉鏈頭移動時，就可能夾到內裡的布料，造成拉鏈頭移動不順。如果是嚴重的捲入內裡布料，更將導致整個拉鏈頭被卡死，完全無法進退，往往需要破壞式的修複。為此，先前的習知技術提出多種防夾拉鏈設計方案，例如WO2014033926A1、US6701584B2、EP3289908A1、CN107567291A、CN106333432A、CN104106888A、CN211298642U等所示。但以上的技術不盡理想，本案申請人曾提出一種防夾拉鏈(專利號M624460，並同時提出發明申請案)，其主要特徵為鏈布內側邊反折成一鏈齒帶，再將鏈齒結合在鏈齒帶前面，然後用一特殊結構的拉鏈頭帶動兩鏈齒帶相鏈合或分開，當拉鏈頭滑動時，其背面的兩翼會在鏈齒帶下方的滑動空間中移動，利用鏈布阻隔作用，因此兩翼不會接觸衣物的內襯，可達成防夾的功能，可以應用成單開尾拉鏈上。Nowadays, zippers are commonly used in clothing, including pockets of clothing, openings of trousers/skirts, or two plackets of coats. However, as long as there is a clothing with an inner lining, when the zipper head moves, it may be caught in the inner fabric. , causing the zipper head to not move smoothly. If it is seriously involved in the inner fabric, it will cause the entire zipper head to be stuck, making it impossible to advance and retreat at all, and often requires destructive repairs. For this reason, prior known technologies propose various anti-pinch zipper design schemes, such as those shown in WO2014033926A1, US6701584B2, EP3289908A1, CN107567291A, CN106333432A, CN104106888A, CN211298642U, etc. However, the above technologies are not ideal. The applicant of this case once proposed an anti-pinch zipper (patent No. M624460, and filed an application for invention at the same time). It is combined in front of the sprocket belt, and then a special structure of the zipper head is used to drive the two sprocket belts to be connected or separated. When the zipper head slides, the two wings on the back will move in the sliding space under the sprocket belt. Cloth barrier effect, so the two wings will not touch the inner lining of the clothes, can achieve the function of anti-pinch, can be applied to a single-open end zipper.

在習知拉鏈技術領域中有一種開尾拉鏈（例如US09549593B2所示），經常應用在外套的門襟，其在一條拉鏈的兩鏈帶之間設有兩拉鏈頭，兩鏈帶的下端設有可卡合與分離的下止裝置。但是，上述本案申請人曾提出的防夾拉鏈構造具有鏈布內側邊反折的結構特徵，與一般的開尾拉鏈的鏈布內側邊無反折的特徵完全不同，因此造成習知的開尾拉鏈之下止裝置不適於使用在雙開尾防夾拉鏈。另外，習知的開尾隱形拉鏈結構中也有鏈布內側邊反折成一鏈齒帶，及將鏈齒結合在該鏈齒帶上的結構設計(例如US5586370A所示)。為此，如何提出一種適用於上述的雙開尾防夾拉鏈及雙開尾隱形拉鏈的下止裝置，能夠穩定住鏈布內側邊的反折狀構造，使其具有更佳的抗橫向拉力強度，且拉鏈下止端更容易穿插等效果即為本創作所要積極克服的課題。In the known technical field of zippers, there is a kind of open-end zipper (such as shown in US09549593B2), which is often used on the placket of a coat.
