Further, described handwriting installing tache is the resilient structure of semi-circular fastener.
Further, the opening part of described semi-circular button is installed an elastic cord.
Further, the inner surface of described shift(ing) ring is with friction line.
Further, the inner surface of described shift(ing) ring is with sawtooth decorative pattern.
Technological merit of the present utility model: adopt technique scheme, picture Straight line unit can be saved student and spend in the time of irising wipe on emphasis, because it is convenient to draw straight line on the page opening, allows the page of irising wipe remain unchanged neatly totally, and emphasis is clear.In having improved classroom learning efficiency, for student's review facilitates, and the design is simple in structure, convenient and practical, is convenient to universal and promotes.
Brief description of the drawings
Fig. 1 is the use structural representation of a kind of aid of drawing straight line of the utility model.
Detailed description of the invention
A kind of aid of drawing straight line as shown in Figure 1, comprise handwriting installing tache 1, pull rope 2, shift(ing) ring 3 and auxiliary straight line bar 4, described pull rope 2 one end are connected with handwriting installing tache 1, and its other end is connected with shift(ing) ring 3, and described shift(ing) ring 3 is enclosed within on auxiliary straight line bar 4.
Described handwriting installing tache 1 is the resilient structure of semi-circular fastener.The opening part of described semi-circular button is installed an elastic cord.Because half opening structure likely cannot stably be fixed together with pen drawing Straight line unit.So, improve again, before the annulus of half opening, increase an elastic cord that elasticity is suitable, help fixing.
The inner surface of described shift(ing) ring 3 is with friction line.The inner surface of described shift(ing) ring 3 is with sawtooth decorative pattern.If because the surface of shift(ing) ring 3 is too smooth, can on paper, arbitrarily slide, cannot draw straight line.So, smooth roller is improved to the roller with sawtooth decorative pattern.
Adopt technique scheme, picture Straight line unit can be saved student and spend in the time of irising wipe on emphasis, because it is convenient to draw straight line on the page opening, allows the page of irising wipe remain unchanged neatly totally, and emphasis is clear.In having improved classroom learning efficiency, for student's review facilitates, and the design is simple in structure, convenient and practical, is convenient to universal and promotes.
The foregoing is only better enforcement one example of the present utility model, be not limited to the utility model, all any amendments of making, be equal to replacement and improvement etc., within being all contained in protection domain of the present utility model within the utility model spirit and principle.
