The invention provides a tensioning platform, which comprises a support component, a radial adjusting component and a clamp locking device (5); the radial adjusting component and the clamp locking device (5) are all arranged on the support component; the radial adjusting component comprises a displacement driving device, a transmission chain (205) and a clamping block (2), wherein one of the two ends of the transmission chain, along the length extension direction, (205) is directly or indirectly connected to the displacement driving device, and the other end of the transmission chain (205) isfixedly connected with the clamping block (2); one or more clamp locking devices (5) is fastened to the support component. The invention also provides a thin film optical surface tensioning platform combination device comprising the tensioning platform. By using the wire cutting technology, an integral profile is processed and cut, the integration of the whole transmission link from the displacement input to output is realized, the integral structure is simplified, and meanwhile, the introduction of a flexible hinge reduces system transmission errors.
