Although the above-mentioned creative case can achieve the originally created creative purpose, it is highly praised by the industry and general operators, but in view of the industry's continuous research and development and continuous innovation in technology, the applicants have made more efforts to study Improvement, making it perfect and practical; plus, the creator's response to countless updates, experimental tests, and summary of consumers' actual operation and use, found that the following problems still need to be further improved: Due to the body And the bottom surface of the shoe is made of a hard metal material, and the seat system directly passes through the threaded section of the bolt to the limit slider screwed inside the shoe to make the seat body It is fastened to the bottom surface of the shoe. However, due to the uneven surface of the riding and the vibration generated when stepping on the pedal, the bolt will often loosen in the reverse direction due to the vibration. Therefore, a small-angle relative rotation phenomenon will be formed between the seat body and the bottom surface of the shoe, so that the shoe will also form a relative shake between the card pedal; in this way, it will not only be shaken Due to the stepping caused by sex, the stepping force applied to the shoes is uneven, which may cause twisting. In addition to the accidental danger of injury, it will also be stepped on due to shaking, which will easily force the seat body and the card pedal to form a relative shaking movement. In addition, the seat body is laterally between the front card portion and the rear card portion The penetrating elongated hole is provided, so that the front clamping part and the rear clamping part are shaken and unevenly stressed, which is likely to cause the seat body to break from the periphery of the elongated hole and can no longer be used. .
