[0041] The first pair of circular holes 28, the second pair of circular holes 29 and the third pair of circular holes 30 are provided with a plane structure around the arc-shaped curved surface, which can uniformly contact with the installed nut or screw rod or bolt or limiting sleeve and bear force uniformly.

[0042] The specific working principle is as follows:

[0043] In the embodiment, for convenience of description, the virtual connection of the first pair of circular holes 28 and the virtual connection of the second pair of circular holes 29 are in the same direction, which are set as X direction;

[0044] The virtual connection of the first pair of supporting ears 26, the virtual connection of the second pair of supporting ears 27, the virtual connection of the third pair of circular holes 30 and the virtual connection of the opposite threaded holes 31 are in the same direction, which are set as Y direction;

[0045] In the embodiment, the X direction and the Y direction are perpendicular to each other.

[0046] The bottom end of the center block 24 is provided with a counterweight 25, and the top end of the center block 24 is provided with a vertical rod 10, and the upper end of the vertical rod 10 is provided with a detection instrument. Due to the vertical downward force of the counterweight 25, the center block 24 and the vertical rod 10 are in a stable state.

[0047] When subjected to vibration, the sealing plug 35 at the end of the piston rod 14 slides inside the piston cylinder 13. When compressed, the gas inside the piston cylinder 13 is slowly discharged through the air hole 36, so as to slow down the shortening of the piston rod 14. Conversely, when stretched, the piston cylinder 13 slowly absorbs the external gas through the air hole 36, so as to slow down the growth of the piston rod 14, thereby playing a role of shock absorption and buffering.

[0048] When subjected to vibration, if the device bears the tilt from the X direction, the adjusting rod 37 transmits the tilt energy to the receiving plate 12 after self-buffering, and the receiving plate 12 transmits the tilt to the second balance cylinder 23 through the first balance cylinder 22. Since the second balance cylinder 23 can rotate around the screw rod connecting the third pair of circular holes 30 and the opposite threaded holes 31, the second balance cylinder 23 tilts along the X direction, thereby unloading the tilt energy of the X direction and ensuring the stability of the center block 24.

[0049] When subjected to vibration, if the device bears the tilt from the Y direction, the adjusting rod 37 transmits the tilt energy to the receiving plate 12 after self-buffering, and the receiving plate 12 transmits the tilt energy to the first balance cylinder 22. Since the first balance cylinder 22 can rotate around the screw rod connecting the first pair of circular holes 28 and the second pair of circular holes 29, the first balance cylinder 22 tilts along the Y direction, thereby unloading the tilt energy of the Y direction and ensuring the stability of the center block 24.

[0050] The embodiment provides two balance cylinders which can rotate in the vertical direction, and vibration reduction is realized.

[0051] The utility model discloses the technical concept of the utility model through the above embodiment, but the utility model is not limited to the above embodiment, namely does not mean that the utility model must rely on the above embodiment to be able to implement. The skilled in the art should understand that the related improvement of the utility model falls within the protection scope and the public scope of the utility model.
