The purpose of this utility model provides a kind of easy to carry, simple in structure; can adjust bevel angle as required; make the operator let nature take its course consciously health to be ajusted automatically; degree of fatigue when alleviating reading and writing can be protected the adjustable reading and writing plate box of portable bevel angle of health.

The utility model is achieved in that the reading and writing plate box that a kind of portable bevel angle is adjustable, by board, put the book plate, pole is formed, its special character is that the lower end of holder book pressing plate, base plate bar being housed and putting the board of book plate links by hinge A and plate box, and its upper end links by hinge B, metal catheter, bolt, pole, hinge C and plate box bottom.

Have putting in the slideway that the book plate is contained in both sides, the board back side of hook book lath in the utility model implementation;

Be contained in by in hinge B and the joining metal catheter of board by the joining pole of hinge C and plate box bottom in the utility model implementation, locate by bolt.Change the relative position of pole in metal catheter by the degree of tightness bolt, adjust the angle of board face and horizontal plane, its adjusting range is 20-85 °.

Holder book pressing plate is installed in two ends by bolt, compression spring and has the right angle hook end and match with board on the base plate bar that can slide up and down in the utility model implementation.

The method that the utility model has changed people's reading for a long time, write and keep flat from structure, books are placed on horizontal plane to be had on the inclined-plane of 20-85 ° of angle, solved because of reading, write need bow, bend over, eye looks down the physical fatigue that causes and unhealthful problem.
