The utility model discloses a novel elevator speed governor with a rope loosening function. The novel elevator speed governor with the rope loosening function comprises a speed governor base, a fixing shaft, a bottom wheel, a steel wire rope sleeve wheel, a speed governor steel wire rope and a pawl action mechanism. Through detachable connection of the bottom wheel and the steel wire rope sleeve wheel, when the speed governor single body is subjected to speed testing to verify the action speed of the speed governor single body, the bolt between the bottom wheel and the steel wire rope sleeve wheel is removed, so that the bottom wheel and the steel wire rope sleeve wheel can rotate independently, and the operation of loosening or removing the steel wire rope of the speed governor is not needed; therefore, the action speed of the speed limiter can be tested. 本实用新型公开了一种自带松绳功能的电梯新型限速器，自带松绳功能的电梯新型限速器包括有：限速器底座、固定轴、底轮、钢丝绳套轮、限速器钢丝绳及棘爪动作机构；通过底轮及钢丝绳套轮的可拆卸连接，对限速器单体进行速度测试来验证其动作速度时，将底轮与钢丝绳套轮之间的螺栓去除，使底轮与钢丝绳套轮可以独立转动，而不需要进行松
