The invention discloses a bike seat folding and position restoring device and belongs to the technical field of bike accessories. A bike seat in the device is a movable part. A bike seat supporting frame is a fixed base body. The fixed base body and the movable part capable of relatively moving in the axial direction of the fixed base body form engaging positioning or disengaging telescopic connection through convex and concave engaging mechanisms which are evenly and continuously distributed; the engaging portion of each convex tooth component is provided with at least one partition groove in the cross section perpendicular to the relative displacement direction; and due to engaging and disengaging of non-complete threads, the folding and stretching functions are achieved. Meanwhile, the device is provided with a pawl mechanism and a floating type locking base, and due to engaging or disengaging of ratchet teeth of the two parts, the position restoring function can be achieved after folding. The bike seat folding and position restoring device achieves the fast telescopic adjusting, locking and positioning aims through the threads or the pawl mechanism. The bike seat folding and position restoring device is easy to manufacture, low in weight, reliable in performance and capable of achieving position restoration, and cost is substantially reduced.
