AI Technical Summary
Existing rotary drive structures are difficult to adapt to diverse needs in different application scenarios, especially due to low efficiency during the conversion between rotation and axial movement.
A rotation drive hub structure was designed. By setting an elastic element between the guide cylinder and the shaft, the pressure arm and the guide cylinder are synchronously engaged. The deformation of the elastic element drives the rotation of the shaft and the guide cylinder, thereby realizing the conversion between rotation and axial movement.
It enables forward and reverse rotation of the central shaft during pressing and releasing, enhancing the flexibility and efficiency of the rotation drive and adapting to the needs of different application scenarios.
