[0034] The contents not described in detail in the specification are all prior art known to those skilled in the art.

[0035] In operation, first, the device is fixedly installed at a suitable position through the mounting plate 11, then the six-column full-phase device body 9 is placed inside the explosion-proof box 1 from the open slot 10, so that the six-column full-phase device body 9 is placed on the placement plate 27, then the threaded rod 32 is rotated, and the threaded rod 32 drives the fixed horizontal plate 34 to move above the open slot 10 when rotating, preventing the six-column full-phase device body 9 from moving out of the explosion-proof box 1, thereby completing the fixation of the six-column full-phase device body 9. When the six-column full-phase device body 9 explodes due to internal failure, the placement plate 27 will be subjected to a force. Since the placement plate 27 is connected to the moving slider 23 through the support plate 25, the movement of the placement plate 27 will drive the moving slider 23 to slide on the slide rod 21, and the spring 22 sleeved on the slide rod 21 will be compressed under the driving of the moving slider 23, and the elastic potential energy of the spring 22 will increase with its deformation, thereby converting the external impact energy or the internally released energy into the elastic potential energy of the spring 22 and storing it, playing a role in buffering and energy absorption.
