the included angle between the first axis X and the second axis Y can be adjusted according to actual needs, for example, can be 45 ° or 60 °, or, as shown in fig. 6, the first axis is perpendicular to the second axis, for example, the moving path of the second base block 2 relative to the first base block 1 driven by the supporting connection member 3 is perpendicular to the moving path of the second base block 2 relative to the supporting connection member 3. In this way, the floating connection device, while having the above-mentioned 4 degrees of freedom, also facilitates the assembly of the floating connection device between the support link 3, the first base block 1 and the second base block 2.
