Abstract:
A screw button switch device, comprising:a slowdown box with a cylinder body, the cylinder body having a plurality of concave gears located around an outer brim of a cylinder bottom;a steel ball press ring, coordinated with an outer radius of the cylinder body of the slowdown box cover;a spring, coordinated with an outer radius of the cylinder body of the slowdown box cover and pressing said steel ball press ring;a stop ring, fitting to said outer radius of the cylinder body of the slowdown box cover, freely rotating, and pressing another end of said spring;a switch base, coordinated with said inner cylindrical radius of said slowdown box;a switch block, coordinated with said inner cylindrical radius of said slowdown box;an output axis, sequentially penetrating a spring, said switch base, vibrating block, and vibrating base which are assembled in said inner radius of the cylinder body of the slowdown box cover; anda switch device, which comprises a stop ring, a upper stop plate, and a screw button, said stop ring having a plurality of screw tracks, each screw track located around a circle with different radius and having different height, said stop ring fitting said outer radius of the cylinder body of the slowdown box cover and freely rotating, said upper stop plate forming a ring frame, said ring frame corresponding to and fitting to said outer radius of the cylinder body of the slowdown box cover, said ring frame having a concave part in a front end and having a plurality of convex parts coordinated with said screw track of the stop ring in a back end, said screw button covering and fixed to an outer part of the stop ring,wherein said screw button switch device is characterized as:said switch base comprises two sets of switch concave gears with appropriate spacing located on an axial plane around the outer brim, a side on which said switch concave gears is located forming an inclined surface, an axial plane of said switch block having two sets of switch convex gears which correspond to said switch convex gears, said switch base and switch block thereby rotating with respect to each other to control the switch convex gears to engage or disconnect with the switch concave gears, and further controlling whether said switch base is moved in radial direction.
