In this way, the multiple springs are symmetrically supported on the lower plate face of the floating plate, and the symmetric arrangement makes the elastic support force received by the floating plate in each direction more balanced.
[0036] In one embodiment, the bottom face of the support groove 11 is provided with spring limiting grooves 15 corresponding to the multiple springs. In this way, the spring can always maintain the correct installation position and working state, so that it can stably provide the floating plate 2 with the elastic support force.
[0037] Specifically, the number of springs is four, and the four springs are respectively arranged corresponding to the four corners of the lower plate face of the floating plate 2.
[0038] Specifically, the bottom end of the base 1 is provided with a sink groove I 13 opposite to and coaxially arranged with the spring limiting groove 15, the spring limiting groove 15 and the sink groove I 13 are communicated through a via I 14, and the via I 14 is coaxially arranged with the spring limiting groove 15.

[0044] In some specific embodiments, the distance between the upper plate face of the floating plate 2 in a free state and the lower end face of the limiting protrusion 31 is less than the thickness of the metallographic slice 10.
