When the transformer is away from the ground, the heat of the transformer can be better dissipated. When the transformer is working, the transformer will vibrate. The compression spring will reduce the vibration generated by the transformer when it is working. The compression spring can effectively absorb and suppress these vibrations to prevent vibration from damaging the equipment.

[0016] (2) In this invention, when the base frame rotates, it will come into contact with the ground. At this time, the base frame will support the equipment and can effectively support the weight of the equipment. When the equipment is not in use, the long block and the support frame will shrink under the elastic force of spring 1, which can effectively reduce the space occupied by the support device. When the transformer vibrates, the hydraulic rod can reduce the vibration from the transformer and reduce the shock absorption burden of the pressure reducing device.

[0017] (3) In this invention, when the push plate continues to move to the left, spring three will contract. When spring three contracts, the push plate will generate a thrust in the direction of the transformer. At this time, the transformer will be fixed left and right by the push plate. When the long plate rotates along the inclined surface of the triangular inclined plate toward the transformer, the long plate will contact the transformer. At this time, the long plate will fix the transformer front and back, which can effectively prevent the transformer from tilting and the position of the transformer from shifting when the transformer vibrates.
