Equal-difference hub concave notch cam shaft

The utility model discloses an equal-difference hub concave notch cam shaft, which structurally comprises an I-shaped hub shaft block, a wheel shaft column body, a lock cap frame ring and a trapezoidal conical cap seat, and realizes that the I-shaped hub shaft block is matched with the wheel shaft column body, and the I-shaped hub shaft block is erected on the wheel shaft column body at equal-difference intervals; the concave-convex property of a notch between a clamping shaft inner buckling block and a buckling sliding pulling frame groove is consistent, and the four-position segmented frame protection wheel shaft column body is linked, so that the operation effect of consistent cam shaft action and consistent fluctuation fall when the regular movement requirement is met is improved, the follow-up wheel shaft column body works synchronously, the adaptability is high, collision and abrasion are avoided, and the service life of the cam shaft is prolonged. And the staggered differential buckling sliding-pulling
