Holding handle and application

The invention belongs to the technical field of 3D printing, and particularly relates to a holding handle and application. The invention provides a holding handle and application. The holding handle comprises an inner core, a first wrapping layer wrapping the outer surface of the inner core and a second wrapping layer wrapping the surface of the first wrapping layer. The inner core is of a rigid rod-shaped structure, the first wrapping layer and the second wrapping layer are both flexible, and the flexibility of the first wrapping layer is larger than that of the second wrapping layer. According to the holding handle, good structural support, grabbing hand feeling, damping and energy absorbing effects, impact and vibration dispersing capacity, grabbing force and ventilation effects can be provided, and the comfort level and safety of the holding handle are both considered. 本发明属于3D打印技术领域，具体涉及一种握持手柄及应用。本发明提供的握持手柄及应用包括内芯、包覆于内芯外表面的第一包裹层和包覆于第一包裹层表面的第二包裹层；内芯为刚性杆状结构，第一包裹层和第二包裹层均具有柔性，且第一包裹层的柔性大于第二包裹层。本发明的握持手柄，可以提供良好的
