[0024] Reference Figure 1-Figure 3 , a structure convenient for connecting a high-precision hollow rotating platform, comprising a work surface 1, a hollow rotating platform body 6 is arranged at the upper end of the work surface 1, two through holes 3 are provided on the work surface 1, and two plug-in plates 8 adapted to the through holes 3 are fixedly installed at the lower end of the hollow rotating platform body 6, a rectangular cavity is arranged inside the plug-in plate 8, and a fixing component for fixing the hollow rotating platform body 6 is arranged inside the rectangular cavity, and the fixing component comprises a fixing block 9 arranged in the rectangular cavity, one side of the fixing block 9 passes through the rectangular cavity, and the fixing block 9 is slidably connected with the plug-in plate 8, and the lower surface of one side extending from the fixing block 9 is an inclined structure, and the other side of the fixing block 9 is elastically connected to the rectangular cavity by a second spring 13, and the second spring 13 is a compression spring, and a toggle groove 12 is provided on the fixing block 9, and the toggle groove 12 is a rectangular structure, which passes through the fixing block 9, and a triangular protrusion is arranged on the right inner side of the toggle groove 12, and the inclined surface of the triangular protrusion faces downward;

[0025] A pull rod 14 is provided through the upper end of the hollow rotating platform body 6, and the lower end of the pull rod 14 extends to the inside of the rectangular cavity and is fixedly installed with a toggle block 10. A circular hole for passing the pull rod 14 is provided on the hollow rotating platform body 6 and the plug plate 8. The toggle block 10 is located inside the toggle groove 12. The toggle block 10 is elastically connected to the rectangular cavity through a first spring 11. The first spring 11 is a tension spring. When the pull plate 7 is not pulled, the toggle block 10 remains unchanged under the action of the first spring 11. The toggle block 10 is formed integrally by a rectangular vertical plate and a trapezoidal block, and the trapezoidal block is located directly below the triangular protrusion;

[0026] A plurality of positioning holes 2 for positioning the hollow rotating platform body 6 are provided on the work surface 1 , and a plurality of positioning rods 4 adapted to the positioning holes 2 are fixedly mounted on the lower end of the hollow rotating platform body 6 .

[0027] Working principle:

[0028] During installation, first insert the positioning rod 4 into the positioning hole 2 to preliminarily position the hollow rotating platform body 6, and then insert the plug plate 8 into the through hole 3. Due to the inclined structure of the fixing block 9, when the fixing block 9 contacts the through hole 3, the fixing block 9 is squeezed to overcome the elastic force of the second spring 13 and shrink, so that the plug plate 8 can be directly inserted into the through hole 3. When the fixing block 9 is aligned with the fixing groove 5, the fixing block 9 is reset under the action of the second spring 13, and the fixing block 9 is inserted into the fixing groove 5 to fix the hollow rotating platform body 6.

[0029] During disassembly, the pull rod 14 is pulled upward by the pull plate 7, and the upward movement of the pull rod 14 drives the toggle block 10 to move upward. The trapezoidal block of the toggle block 10 squeezes the triangular protrusion of the toggle groove 12, causing the fixed block 9 to shrink. At this time, the hollow rotating platform body 6 can be lifted to complete the disassembly.
