[0026] As a further implementation of this solution, the tension spring 461 and the threaded clamping column 462 are on the same axis, the groove 463 on the column matches the clamping groove 52, the central axis of the threaded clamping column 462 and the central axis of the nut 464 are on the same straight line, and one side of the nut 464 is in contact with the inner side of the inner slide rod 51. This design facilitates the transmission of force between the components and further applies prestress to the device.

[0027] As a further implementation of this solution, the rubber strip 553 is semi-cylindrical, the notch 554 is rectangular, the center of the notch 554 is coplanar with the center of the short post 45, the height of the notch 554 is the same as the diameter of the short post 45, and the horizontal projection of the support leg 552 is trapezoidal. This design ensures that the short post 45 passes through the notch 554, improving the fit between the components.

[0032] Workflow: When installing the device, plan the installation position of the outer rod assembly 4 according to the size of the server and the location where it needs to be installed, then clamp the outer rod assembly 4 to be installed on the mechanism bracket 1, pass the fixing bolt 3 through the mounting hole 2 and the front threaded hole 43, fix the outer rod assembly 4 and the mechanism bracket 1 together, and then pass another fixing bolt 3 through the side threaded hole 44 and the mounting hole 2 to reinforce the installation of the outer rod assembly 4 to ensure that the outer rod assembly 4 is firmly and reliably fixed, then insert the threaded clamping column 462 into the clamping groove 52 so that the upper groove 463 of the column matches the clamping groove 52, rotate the nut 464 to screw the nut 464 and the threaded clamping column 462 together, thereby fixing the threaded clamping column 462 and the inner slide rod 51 together, and then pull the inner slide rod 51. When the inner slide rod 51 moves, the short column 45 slides inside the sliding transverse groove 53, and at the same time the short column 45 squeezes the support assembly in the tilted state. When the inner rod 51 is moved a certain distance, the inner rod 51 is fixed to the mechanism bracket 1 using the fixing bolt 3. At this time, the tension spring 461 generates tension on the threaded clamping column 462 in order to restore the deformation, so that the connecting assembly 46 can apply a certain prestress to the inner rod assembly 5 to prevent the inner rod assembly 5 from shaking. While the support assembly 55 plays the role of internal support for the inner rod 51, it can also be used to judge whether the inner rod assembly 5 is deformed by observing the deformation of the support assembly 55 during subsequent use, so as to replace it in time.
