Eccentric compensating error type shaking frame

The invention relates to an eccentric compensating error type shaking frame, belongs to spinning machinery and relates to the innovation for increasing parallelism of an annular spindle spinning machine of a drafting pressing shaking frame. The eccentric compensating error type shaking frame comprises a shaking frame base (1), a shaking frame body (2), a hinge shaft for shaking frame base and shaking frame body, an upper roller holding mechanism and a pressurizing/pressure-releasing mechanism. According to the invention, the hinge shaft for shaking frame base and shaking frame body is changed into an eccentric shaft (3) from the original cylinder shaft. When the eccentric shaft (3) is twisted, the shaking frame body (2) can suitably swing relative to the shaking frame base (1), so that the accumulated error to the parallelism caused by the related parts of the shaking frame is eliminated. The eccentric compensating error type shaking frame has the advantages that: economical precise manufacturing parts can be
