The utility model discloses the during operation, with the tight drawing board of metal limit tip looks connection hoop, cramp the drawing board after, go into the drawing chi card drawing chi fixed subassembly, the drawing chi can be realized reciprocating the drawing line by the fixed subassembly of push-and-pull drawing chi, can dismantle the drawing chi that does not use simultaneously and use as ordinary ruler, take off the card cap, draw the friction gently on the line type grinds the seam with ordinary pencil, can form the nib of different line types, corresponding line type is drawn to the accuracy, the pen tail of pencil can be entangled to the cover pen slot on the card cap, make things convenient for carrying of pencil.

The utility model adopts the above technical scheme, compared with the prior art, the beneficial effects lie in, design plug-type parallel chi and drawing board are used in coordination, install two drawing rulers of movable cutting ferrule fixed on the long bearing, and two drawing rulers can up-and-down motion thus draw level and perpendicular straight line, slightly lift the ruler when sliding and can avoid smearing the drawing paper dirty, in addition two rulers can all be dismantled and conveniently used, it has greatly improved drawing efficiency and has not influenced the training of the basic merit of drawing, has avoided the trouble of carrying the T-square, the design of the linear mill groove has solved the problem of difficult to cut out the exact nib size; the card cap is sleeved on the card body, so that the scratch of the hand caused by the sharpness of the line type grinding seam can be prevented, the device can fully hold the characteristics of the hand drawing performance chart in training, the personality of students can be exerted, and the solid basic drawing work can be ensured.

In order to facilitate carrying of the hand drawing device, the long bearing shaft is provided with an adjustable strap.

In order to enable the drawing board to have the advantages of being light, thin, portable, waterproof, firm, not prone to deformation and the like, the surface of the drawing board is smoother, tough, not prone to damage drawing paper and not prone to scratching, the drawing board is made of PP plastics.

In order to effectively relieve visual fatigue caused by drawing for a long time and provide more effective protection for eyes, the color of the drawing board is light green.

In order to enable the metal edge to hoop the drawing board more firmly, the fixing piece is a screw.

In order to clamp the drawing in a cross shape during installation and bring convenience to carrying of the drawing, the thickness of the drawing ruler is 1 mm.

In order to grind accurate line shapes and shorten the time of using the pencil sharpener and greatly improve the drawing efficiency, the sizes of the multiple line-shaped grinding seams are 1.4mm, 1.0mm, 0.7mm, 0.5mm, 0.35mm and 0.25 mm.
