Considering the radial component and azimuthal component of the vortex beam in focusing contribution, the tightly focusing formula of Cylindrical Vortex Beams(CVB) was amended. The CVB focusing intensity distribution was afresh investigated in the focal region by using amendatory tightly focusing formula. The results show that the flattopped focus and the focal hole are proposed by adjusting the Polarization Rotation(PR) angle, NumericalAperture(NA) and the Aperture Blocking(AB). The adjustably confined flattopped focus can be generated by adjusting PR angle. And the flattopped focus can be obtained for the relative small NA with the increasing of AB. The narrower focal hole can be obtained in the higher NA when AB is larger.
