[0022] Such as Figures 1-4As shown in the figure, the ultra-stable platform for atomic force detection provided in this embodiment includes a fixed bottom plate 1. Three wear-resistant sliding pieces 11 are embedded on the upper surface of the fixed bottom plate 1. The three wear-resistant sliding pieces 11 are distributed in a triangular shape, and the three wear-resistant sliding pieces 11 are respectively located at the two side positions of the fixed bottom plate 1. A sliding member 21 is slidably connected to the upper surface of the wear-resistant sliding piece 11. A threaded connector 22 is inserted into the upper surface of the sliding member 21. An activity platform 2 is commonly threadedly connected to the three threaded connectors 22. Two motor coils 12 are fixedly installed on the upper surface of the fixed bottom plate 1. The two motor coils 12 are symmetrically distributed about the central axis of the fixed bottom plate 1.

A plurality of convex blocks are provided on the lower surface of the sliding member 21. The plurality of convex blocks are in contact with the wear-resistant sliding piece 11. The convex blocks are used to reduce the friction between the sliding member 21 and the wear-resistant sliding piece 11, making the sliding between the sliding member 21 and the wear-resistant sliding piece 11 smoother. The material of the wear-resistant sliding piece 11 is a very hard and very wear-resistant material. Through the mutual cooperation of the motor coil 12 and the 23-motor magnetic rail, the 23-motor magnetic rail drives the magnetic rail mounting plate 24 to move under the action of the motor coil 12. The two magnetic rail mounting plates 24 drive the activity platform 2 to move together. The activity platform 2 drives the threaded connector 22 to move. The threaded connector 22 drives the sliding member 21 to move on the wear-resistant sliding piece 11. Under the action of the wear-resistant sliding piece 11, the activity platform 2 is super-stably moved.

[0023] Secondly, as Figure 1 、 Figure 2 and Figure 3 shown, two limiting blocks 13 are bolted on both sides of the fixed bottom plate 1. The limiting blocks 13 are located at the four corner positions of the fixed bottom plate 1. The four limiting blocks 13 are all slidably connected to the activity platform 2.

The fixed mounting members 14 are used for fixedly installing and supporting the ultra-stable platform for atomic force detection.

[0027] As shown in Figures 1-4 , the principle of the ultra-stable platform for atomic force detection provided in this embodiment is as follows: When using this ultra-stable platform for atomic force detection, through the mutual cooperation of the motor coil 12 and the 23 motor magnetic rail, the 23 motor magnetic rail drives the magnetic rail mounting plate 24 to move under the action of the motor coil 12. The two magnetic rail mounting plates 24 jointly drive the movable platform 2 to move. The movable platform 2 drives the threaded connecting member 22 to move. The threaded connecting member 22 drives the sliding member 21 to move on the wear-resistant sliding piece 11. The material of the wear-resistant sliding piece 11 is a very hard and very wear-resistant material. Under the action of the wear-resistant sliding piece 11, the movable platform 2 is stably moved.
