Thrust structure of brake mechanism

A push structure of a brake mechanism, said brake mechanism involving a turning block installed in an outer casing, on the outside of the outer casing being a swing member to drive the turning block, on the other side of the turning block inside the outer casing being a push block, said push block driven by the turning block for parallel movement, and on the other side of the push block being arranged in sequential order a moving member and a flexible member, said outer casing involving an outer cover to restrict the above components inside, a brake block being protruded out of the outer casing and tightened onto the moving member, to perform braking operation on a brake disc;

• wherein on the end surface of the turning block and opposite the push block is the formation of several cone-shaped elongated grooves, on the bottom of each cone-shaped elongated groove is the formation of an incline gradually ascending toward the direction of rotation of the brake, and on the end surface of the push block is the formation of matching cone-shaped elongated grooves, between respectively corresponding cone-shaped elongated grooves being accommodated a cone-shaped roller post, the cone-shaped roller post rolling along the incline of the cone-shaped elongated grove, producing an ascending effect, thereby comprising a thrust structure of brake mechanism, between the cone-shaped elongated grooves is a radius to accommodate the cone-shaped roller post.
