Transformer circuit fixing device for weak current engineering

The utility model discloses a transformer line fixing device for weak current engineering. The transformer line fixing device comprises a transformer main body, two groups of limiting frames, a fixing assembly and a power transformation assembly. According to the utility model, the fixing assembly is arranged, the limiting frame is sleeved on the side wall of the transformer main body, the threaded rod is rotated, and the threaded rod moves downwards under the limiting of the limiting block, so that the clamping plate moves downwards, the limiting frame can be fixed, subsequent installation and fixation of a circuit are facilitated, the height of the limiting cylinder can be adjusted by using the telescopic rod and the fixing pin, and the use is convenient. A circuit penetrates through the limiting cylinders, the drawing rods are pulled, the drawing rods move to drive the clamping plates to move, the circuit can be clamped and fixed under the resilience force of the springs, the circuit is prevented from fall
