The invention provides a handheld spring with gears, relates to the technical field of chest expanders, and solves the problems that an existing chest expander is inconvenient to carry in the use process, and the gears of the chest expander cannot be quickly adjusted, so that the existing chest expander is inconvenient to use, and a user is easily injured due to fact that a spring pops out in process of disassembling the spring. The handheld spring comprises a limiting mechanism, the limiting mechanism is inserted into the handle, and a limiting ball is separated from a limiting groove throughsliding of an inhaul cable along a rolling wheel A and a rolling wheel B. Therefore, purpose of adjusting tightness of the handheld spring by adjusting different amplitudes is achieved. By means of the design, gear adjustment can be rapidly conducted on the handheld spring, and therefore the purpose of improving the use efficiency is achieved. 本发明提供一种带有档位的手握式弹簧，涉及拉力器技术领域，解决了现有的拉力器在使用过程中存在着不便携带，以及无法快捷的对拉力器的档位进行调节，因此会造成使用不
