The utility model provides a suction cup type rotary hook which comprises a suction cup assembly, a hook assembly and a connecting rod assembly, and the connecting rod assembly comprises a first rod end suitable for being connected with the suction cup assembly, a second rod end suitable for being connected with the hook assembly and at least one rotary joint. The suction cup assembly comprises a first seat body, an elastic adsorption piece, a second seat body, a column body and a first guide device, the first seat body comprises a first cavity with a first cavity opening and a first cavity bottom and a first back plate, the adsorption piece is suitable for sealing the first cavity opening, and the second seat body is arranged close to the first cavity bottom; comprising a driving cambered surface gradually getting away from the first base body, the column body comprises a first column end suitable for being connected with the center of the adsorption piece and a second column end with a driving shaft, the driving shaft is in sliding fit with the driving cambered surface, and the first guiding device is suitable for guiding the column body to stretch in the axial direction to drive the adsorption piece to deform. According to the utility model, the sucker assembly can be installed on a multi-angle plane, and the direction and the position of the hooking assembly can be adjusted.

The application provides a vortex optical fiber probe, a preparation method, a scanning probe and a micro-nano manipulation system. The vortex optical fiber probe comprises: an optical fiber, the optical fiber is subjected to a tapering treatment to form a base and a transition zone connected with the base; and a micro-nano structure located at one end of the transition zone, the micro-nano structure comprises a spiral phase plate and a needle tip at the end of the micro-nano structure, and the spiral phase plate and the needle tip are both prepared by 3D printing, wherein the cross-sectional diameter of the end is between 100 nm and 10 μm. The vortex optical fiber probe, the preparation method, the scanning probe and the micro-nano manipulation system can realize optical and mechanical detection on a micro-particle sample through a probe prepared based on a general optical fiber and 3D printing, the probe preparation process is simple, the cost is low, and the universality is strong.
