[0025] In this embodiment, when installing the gyroscope, the fixed block 3 on the gyroscope support is accurately inserted into the installation cavity of the base 1, at this time, the group of rectangular tubes 5 in the installation cavity are in the initial state, and the fixed block 3 is not limited, then the driving mechanism arranged in the installation cavity is operated, the driving mechanism generates a driving force acting on the group of rectangular tubes 5, so that the group of rectangular tubes 5 relatively slide in the installation cavity. With the sliding of the rectangular tubes 5, they gradually approach the fixed block 3 and finally insert one side of the fixed block 3. When the rectangular tubes 5 are completely inserted into one side of the fixed block 3, a close fitting relationship is formed between the rectangular tubes 5 and the fixed block 3, and the friction force and mechanical constraint force generated by the fitting can firmly fix the fixed block 3 in the installation cavity of the base 1, thereby completing the installation operation of the gyroscope support. The installation is completed by driving the rectangular tubes 5 to insert one side of the fixed block 3 through the driving mechanism, without tightening the bolts one by one, greatly simplifying the installation steps and improving the installation efficiency.
