[0014] The distance between the hook seats at the upper and lower ends is the same as the distance between the butt joints on the same side.

[0015] Advantages:

[0016] The detachable arrangement of the present application can be quickly and conveniently disassembled compared with the technical solution of fixing by screws, and the later maintenance is simpler. Compared with the technical solution of clamping and locking by the telescopic mechanism, the fixed and locked anti-vibration performance of the present application is higher, and can meet the application of large load and large volume equipment in strong impact vibration scene.
