Rocker type steering wheel key

The invention discloses a rocker type steering wheel key, which comprises a steering wheel body, a mounting shell is fixedly mounted on a spoke of the steering wheel body, an upper cover plate is embedded in the upper surface of the mounting shell, a limiting cover is arranged in the mounting shell, and a universal spherical block is movably mounted in the limiting cover; the top of the universal spherical block is fixedly connected with a connecting rod, the top of the connecting rod is fixedly connected with an adjusting block, and the bottom of the universal spherical block is fixedly connected with a universal sensor. When the limiting cover is pressed, an elastic clamping block generates elastic deformation to enter a special-shaped clamping groove, and the elastic clamping block restores to the original state after entering the special-shaped clamping groove; at the moment, the elastic clamping block cannot be pulled out of the special-shaped clamping groove, fixing of the limiting cover is completed, t
