ABSTRACT:
A clipboard structure includes a board having a seat formed on one end of an upper surface. A recess is formed in an outer end of the seat. A clamping element has two legs disposed in the recess. A spring element has two free ends fixed to the legs of the clamping element. The spring element can be easily assembled in the recess of the seat. The spring element biases the legs of the clamping element so that a front end of the clamping element is forced to abut against the board.
