The present invention provides a knob, the knob includes a base, an upper cover covering on and fixedly connected to the base, and a buckle hinged on the upper cover and configures for rotating the base and the upper cover. A securing assembly configured for preventing the buckle from swaying is arranged in the upper cover. A containing groove is defined in the upper cover, the securing assembly includes a spring received in the containing groove and two sets of abutting assemblies, each set of the abutting assemblies includes a first rotating shaft and a second rotating shaft, one end of the first rotating has a first concave-convex surface, the first concave-convex surface engages with the second concave-convex surface, the other end of the first rotating shaft is fixedly connected to the buckle, and the other end of the second rotating shaft is inserted into an end of the spring. When the knob is not adjusted, the buckle and the upper cover are at the same level; and when the knob needs to be adjusted, the buckle is rotated to be perpendicular to the upper cover. In this way, the knob can be adjusted conveniently and is suitable for an electrical appliance or a machine with requirements for surface smoothness. The present invention further provides a massager adopting the knob. |
