The invention relates to the technical fields of power equipment and temporary construction power utilization erection, in particular to a novel controllable easy-to-lock temporary cable bracket. A bearing platform is connected to the upper portion of a foot stand, and a cable trough is connected to the bearing platform and is a controllable locking device. The cable bracket has the characteristics of factory customization, simple and convenient on-site construction operation and good stability. During the operation process, the stability of cable erection is ensured, and the reliability and safety of a construction site are enhanced, so that the operation efficiency is improved. The cable trough adopts a fireproof silica gel pad, and the bracket adopts a glass fiber reinforced plastic insulating material, so that the main body design insulativity of the cable bracket is enhanced, the mistaken electric shock phenomenon is avoided, the construction cable is protected, the humanized design is emphasized, the personal safety of operating personnel is greatly guaranteed, and the high efficiency, safety and economy of power construction can be remarkably improved.
