Flexible fixing device for cable mounting and erecting

The invention relates to the field of cable installation, in particular to a flexible fixing device for cable installation and erection, which comprises a fixing seat, a center clamping mechanism, an outer side clamping mechanism, a center elastic reset piece and an outer side elastic reset piece, the device is provided with the center clamping mechanism distributed in a triangular mode, the set of outer side clamping mechanisms arranged in a mirror symmetry mode, and the center elastic reset piece which is fixed to the center clamping mechanism, installed on the fixing base and capable of sliding in the vertical direction. The outer side elastic reset piece is fixedly connected with the outer side clamping mechanism, mounted on the fixing seat and capable of sliding in the horizontal direction, and through a three-point fixing mode in triangular distribution, the cable drives the center clamping mechanism to move upwards and drives the outer side clamping mechanism to move horizontally when being stressed, s
