Unverified拉杆为适应折叠设计做了轻量化处理，拖拽重物时稳定性和手感弱于传统铝合金多段拉杆，长期高负荷使用需留意耐久度79% similarUnverified固定方式牢固度与拆卸便利性权衡：金属钢丝绳最牢但需工具或较难更换，弹力搭扣拆装方便但长期使用会松弛，长途频繁托运优先牢固度79% similarUnverified支撑强度越高（钢条越多越硬）制动效果越好但活动越受限，日常防护选2根软支撑条即可，硬支撑仅用于急性期短期制动78% similarUnverified拉杆结构强度是隐藏故障点，选铝合金一体成型多节拉杆（内嵌式），避免外露单杆拉杆；测试时全部拉出左右晃动，间隙越小做工越好，间隙大长期使用易松动卡顿78% similarUnverified不适合需要承受较大拉力的重物捆扎场景（如搬家打包重箱），拉力强度仅为轻载级别，重物易松脱78% similar
