Abstract
A stop transmission mechanism includes: a ratchet, wherein elastic teeth are provided on a periphery of the ratchet; a claw provided at a radical side of the ratchet, comprising a fixed end and a moving end which rotates around the fixed end, wherein a claw portion to be engaged with the elastic teeth is provided on the moving end; and a tension spring, wherein one end of the tension spring is fixed, and the other end of the tension spring is mounted on the moving end of the claw, for providing a force which drives the claw portion towards the ratchet; wherein the elastic teeth are made of an elastic material; when the claw portion of the claw is buckled on the elastic teeth by the force of the tension spring, the ratchet is flexibly fixed; when external driving force is large enough, sliding tooth happens.
