The invention discloses a vacuum optical tweezers system for suspended nanoparticles. The vacuum optical tweezers system comprises a vacuum optical trap generation module, a vacuum cavity module, a signal collection module and a support module, the vacuum light trap generation module and the signal collection module are both located outside the vacuum cavity module and located on the two sides of the vacuum cavity module along a light path respectively. The vacuum light trap generation module, the vacuum cavity module and the signal collection module meet the following conditions: the working distance of the vacuum light trap generation module is greater than the optical thickness of the front cavity mirror; the sum of the optical thickness of the front cavity mirror, the optical thickness of the rear cavity mirror and the distance between the front cavity mirror and the rear cavity mirror is smaller than the sum of the working distance of the vacuum light trap generation module and the working distance of th
