The buffer assembly comprises a first buffer plate, at least one first buffer part, a buffer cavity formed between the first buffer plate and the bottom or top of the shell, a containing cavity formed between two first buffer plates, the first buffer part arranged in the buffer cavity, the first buffer part comprising a first support frame, a first piston rod and a first spring, the first spring arranged in the first support frame, the first buffer plate slidably connected with the circumferential sidewall of the shell, the first support frame connected with the bottom or top of the shell, one end of the first piston rod connected with the first buffer plate, the first piston rod slidably connected with the first support frame, the other end of the first piston rod connected with one end of the first spring through the first support frame, the other end of the first spring connected with the bottom or top of the shell, and the core component of the durable anti-falling cross-station phase calibrator arranged in the containing cavity, so that the first spring drives the first buffer plate to move up and down to buffer the core component of the durable anti-falling cross-station phase calibrator in the containing cavity.

2. The ruggedized phase calibrator across station as claimed in claim 1, wherein, The first buffer part is two in number and symmetrically arranged on both sides of the buffer cavity in the same longitudinal section.

3. The ruggedized phase calibrator across station as claimed in claim 2, wherein, The buffer assembly further comprises a second buffer part arranged in the buffer cavity, the second buffer part comprising a slide rod, two second springs, two sliding blocks and two rotating rods, the slide rod arranged between two first support frames, the two second springs and the two sliding blocks symmetrically arranged on the slide rod, and the two rotating rods symmetrically arranged in the buffer cavity, two ends of the slide rod connected with the first support frames, the second springs wound around the slide rod, one end of one of the second springs connected with the side of the first support frame and the other end connected with the sliding block on the same side, the bottom of the sliding block rotatably connected with one end of the rotating rod on the same side, the other end of the rotating rod rotatably connected with the first buffer plate, and the rotating rod rotatable to drive the sliding block to move on the slide rod to compress or stretch the second spring.

4. The ruggedized phase calibrator across station as claimed in claim 3, wherein, The second buffer part further comprises a third spring arranged between the two sliding blocks, the third spring wound around the slide rod, and the original length of the third spring equal to the distance between the two sliding blocks.

5. The ruggedized phase calibrator across station as claimed in claim 3 wherein, The second buffer part further comprises two fixing blocks, one end of the fixing block connected with the slide rod and the other end connected with the first support frame, and the fixing block further connected with the second spring.
