What is it made of?

01 外叉双爪

镀铬钢

两片外侧薄刃围绕中间爪口运动;支耳具贯通轴孔。

02 内叉双爪

镀铬钢

内爪与外爪在厚度方向交错而非实体互穿。

03 外爪指托

ABS

宽面指托连接外叉背梁。

04 内爪指托

ABS

内侧指托随内叉运动。

05 铰轴及铆帽

钢

贯通四片支耳的轴孔。

06 扭转回位弹簧

弹簧钢

绕铰轴的弹簧和抵住指托的两腿;仅作形变示意。

How do the parts work together?

交错的薄钢爪插入钉冠下方;挤压两侧指托,使爪口合拢并向上撬起钉冠。

操作联动与独立展开分离;不模拟受力、断裂或摩擦。

Model scope and approximations

AI-assisted educational schematic, not manufacturing CAD. Materials, proportions and movements are limited to this model's description.

演示空载爪口收合,不模拟钉脚塑变或纸张破损;回位弹簧按弯曲腿解释,不作应力仿真。
