晾衣杆卡扣Clothesline clip

厂家自带的不锈钢晾衣杆卡扣时间一长就脆开裂了，这卡扣的必要性是包锋利的边，防止弄破衣物或被子，有存在的必要。用科学解决科学问题，用3d打印的游标卡尺测量尺寸，设计一个耐用的卡扣。材料采用tpu，软材料包着更好，更耐用。

The stainless steel clothesline buckle provided by the manufacturer will become brittle and crack over time. The necessity of this buckle is to wrap the sharp edges to prevent breaking clothes or blankets. Solve scientific problems with science, measure dimensions with 3D printed vernier calipers, and design a durable snap fastener. The material is made of TPU, which is better and more durable when wrapped in soft materials.
