  • Adjusting mechanism with a helical spring of large diameter
    Patent number: 7293764
    Abstract: An adjusting mechanism with a spring, particularly an adjusting mechanism with a helical spring of large diameter, is disclosed, the thread grooves of an inner bore of a rotation member being primarily used to allow the helical spring of large diameter fixed to the spring-fixed base to glide. When the rotation member rotates and axially shifts, the number of compressed coils of the helical spring of large diameter changes, thereby a spring coefficient of the helical spring of large diameter is changed.
    Type: Grant
    Filed: February 3, 2006
    Date of Patent: November 13, 2007
