The embodiment of the invention discloses a linkage rotary shaft and electronic equipment. The linkage rotary shaft comprises a main shaft body, a sliding block, a transmission bar, a gear set and a vice shaft body. The main shaft body comprises a first shaft core and a first rotary shaft body, and the first rotary shaft body is located on the periphery of the first shaft core and rotates around the first shaft core; a sliding groove is formed in the first rotary shaft; at least part of the sliding block is embedded into the sliding groove, the sliding block interacts with the sliding groove when the first rotary shaft rotates, and the sliding block makes horizontal movement in the extension direction of the first shaft core; the transmission bar is fixedly connected with the sliding block and makes horizontal movement along the sliding block; the gear set is connected with the transmission bar and rotates along horizontal movement of the transmission bar; and the vice shaft body comprises a second shaft core and a second rotary shaft body, a gear matched with the gear set is arranged on the outer surface of the second rotary shaft, the second rotary shaft body rotates around the second shaft core along rotation of the gear set, and the second shaft core is perpendicular to the first shaft core.
