A fixing block 24 is fixedly installed at the bottom of the movable plate 21, a connecting rod 25 is hinged to the bottom of the fixing block 24, a moving block 26 is hinged to the bottom end of the connecting rod 25, a sliding rod 27 is fixedly installed on the inner side wall of the mounting frame 1, and the moving block 26 is slidably connected to the sliding rod 27. A second spring 28 is fixedly installed on one side of the moving block 26, and one end of the second spring 28 is fixedly connected to the mounting frame 1. The shock-absorbing component 2 further includes a limiting block 29, and the limiting block 29 is fixedly connected to one end of the sliding rod 27. Mounting plates 6 are fixedly installed on the top and bottom of the mounting frame 1 respectively, and a strip-shaped groove 7 is formed on one side of the mounting plate 6.

[0032] In this embodiment, first, the mounting frame 1 can be mounted to the device by bolts through the strip-shaped slots 7 and the mounting plate 6. Then, when the transformer body 3 vibrates, the transformer body 3 first transmits the force to the movable plate 21, and then the movable plate 21 squeezes the damper 22 and the first spring 23 to contract. At the same time, the movable plate 21 drives the connecting rod 25 through the fixed block 24 to squeeze the movable block 26 to slide on one side of the sliding rod 27, so that the movable block 26 can squeeze the second spring 28 to contract, achieving a good shock absorption effect to prevent damage caused by excessive vibration.

[0033] Referring to Figures 1 to 5 , in one aspect of this embodiment, a disassembly and assembly component 8 is provided at the top of the transformer body 3. The disassembly and assembly component 8 includes a protective shell 81 and a third spring 82. The protective shell 81 is arranged above the transformer body 3. The third spring 82 is fixedly connected to one side of the protective shell 81. One end of the third spring 82 is fixedly connected with a sliding plate 83.

[0034] In this embodiment, pulling the sliding plate 83 can squeeze the third spring 82 to contract, so that the clamping rod 84 can be retracted into the protective shell 81. Then, the positioning plate 9 and the positioning rod 10 are clamped together to complete the fixing work.

[0036] In this embodiment, during the up and down movement of the movable plate 21, it will slide inside the stabilizing grooves 5 through the stabilizing blocks 4, making its movement more stable.

[0037] Working principle: First, the mounting frame 1 can be mounted to the device by bolts through the strip-shaped slots 7 and the mounting plate 6. Then, when the transformer body 3 vibrates, the transformer body 3 first transmits the force to the movable plate 21, and then the movable plate 21 squeezes the damper 22 and the first spring 23 to contract. At the same time, the movable plate 21 drives the connecting rod 25 through the fixed block 24 to squeeze the movable block 26 to slide on one side of the sliding rod 27, so that the movable block 26 can squeeze the second spring 28 to contract.

[0038] Pulling the sliding plate 83 can squeeze the third spring 82 to contract, so that the clamping rod 84 can be retracted into the inside of the protective shell 81. Then, the positioning plate 9 and the positioning rod 10 are clamped together to complete the fixing work. After that, releasing the sliding plate 83 allows the third spring 82 to reset, so that the clamping rod 84 can be clamped with the clamping plate 85 to complete the installation work of the protective shell 81.
