when the pull chest expander 200 rotates, a mechanical pulling force is generated, and since the casing assembly 400 and the chest expander 200 are screwed together, the rotation of the chest expander 200 causes the casing assembly 400 to rotate synchronously, and because of the assembly relationship, the detection assembly and the middle shaft 100 are in a static state. Therefore, the chest expander 200 is pulled to rotate, and the reflector 410 (gray code reflector) on the housing 420 rotates around the corresponding circle center of the three optical signal transceivers 320 (reflective optical coupler switches). The reflection-type optical coupling switch acquires a switch signal through alternation of black and white areas of the Gray code reflector plate, so that data such as pulling direction, pulling speed, pulling acceleration, pulling stroke and the like are obtained.
