Non dead-angle universal soft shaft that twists in tight corners, enabling easy installation in confined spaces. Working principle - During bending, the outer shell and the internal soft rod separate. - Only the internal rotation occurs; the outer shell does not rotate with it, reducing wear on enclosing components. Key benefits - 360 degree twisting capability in narrow spaces and corners without dead angles. - Flexible inner rod with a stationary outer shell during operation for smooth, reliable performance. - Universal design suitable for a range of devices and applications. - Includes 3 pieces for versatile use in multiple setups. Specifications and compatibility - Type: universal soft shaft with inner rotating rod and outer shell - Function: enables full rotation in confined installations while keeping the outer shell stationary - Quantity: 3 pieces Use scenarios - Automotive or machinery work in tight engine bays or dashboards where cords and shafts must bend around obstacles. - Robotics and automation projects with compact enclosures requiring flexible drive shafts. - DIY or model-building tasks near walls, corners, or other obstructions where conventional shafts cannot fit.
