Spin riveting tool suitable for inserting needles of multiple specifications

The spin riveting tool comprises a base, a spin riveting mechanism, a positioning pin, a positioning sleeve, a limiting assembly and a pressing mechanism, the spin riveting mechanism comprises a driving piece, a driving handle, a fixing base and an upper cover, a plurality of holding blocks are arranged in the fixing base in a sliding mode, and the moving tracks of the holding blocks are distributed in a radial mode with the positioning pin as the center. When the upper cover rotates in the forward direction, the holding blocks are driven to synchronously get close to the positioning needle so as to extrude the inserting needle arranged on the positioning needle in a sleeving mode, when the upper cover rotates in the reverse direction, the holding blocks are driven to synchronously get away from the positioning needle, the pressing mechanism is used for providing downward pressure for the inserting needle placed in the positioning sleeve so as to prevent the inserting needle from moving in the axial direction
