Claims

[Scope of utility model registration request]

In a flexible parallel ruler in which a cursor side link and a head support link are connected via a parallel movement mechanism so that the head part and scale are moved up and down approximately parallel to the drawing board surface, the cursor side link and the head support link are connected. A support lever is provided between the link or the member that moves up and down along with the head support link, with one side serving as a swing fulcrum and the other serving as a push-up part, so that it can swing freely along the vertical direction of the scale. A push-up spring member is provided between the fulcrum side and the support lever,
When the support lever moves upward from the position where the head part and the scale contact the drawing surface, the spring action angle of the push-up spring member with respect to the line connecting the swing fulcrum of the support lever and the force application point of the push-up spring member A head part support adjustment device for a universal parallel ruler, which is configured to increase in height and is provided with a height adjustment stopper that adjusts the push-up position of the support lever by coming into contact with the support lever.
