For the above technical problem, the utility model provides a kind of T-square.

This T-square described in the utility model, including blade, blade both ends are all provided with and its rigidly connected ruler handle, ruler handle For semicircle protractor, two kinds of different scales of ratio are divided on blade surface, T-slot, T-slot packet are set along blade direction surface The auxiliary scale holding tank on top and the slide block slot of lower part are included, sliding block is set in slide block slot, center is vertically and fixedly provided with connecting rod, and connecting rod is stretched Going out outside T-slot, the perpendicular angled disk of fixation at the top of connecting rod, angle disk is equipped with auxiliary scale with blade, and auxiliary scale is equipped with groove, Connecting rod passes through groove, auxiliary scale can be dynamic by shaft rotation of connecting rod, and auxiliary scale can be slided using groove as guiding, and auxiliary scale holding tank is used for Receiving to auxiliary scale；

Wherein：

Angle disk sets spring-housing groove with connecting rod junction, and thrust spring, thrust spring are set on spring-housing groove inner wall It is sleeved on connecting rod, thrust spring is used to be in auxiliary scale pushing when auxiliary scale holding tank, prevents auxiliary scale from being taken off out of auxiliary scale holding tank Go out；

Length scale is also set in auxiliary scale.

It is 1 that ratio is divided on blade surface：100、1：300 or ratio be 1：200、1：400 scale.

Auxiliary scale is identical as the size of auxiliary scale holding tank.

The ruler handle at blade both ends is respectively positioned on the lower surface of blade.

Angle disk material is transparent material, viewing angle when auxiliary scale being facilitated to rotate.

The utility model compared with prior art, has the advantages that.

(1) the utility model sets two kinds of scale graduations, such drawing people up and down and draws 1 again:When drawing except 100, just It can be to avoid the serious problems of the drawing mistake caused by oneself calculating mistake；

(2) the utility model blade is equipped with auxiliary scale, and auxiliary scale can be rotated and be slided, while being equipped with angle disk, in pair Can be drawn under ruler effect with straight line at any angle under blade different location, be additionally provided with scale in auxiliary scale, can accurately draw institute The straight line of length is needed, while auxiliary scale is when not in use, auxiliary scale holding tank can be placed in and accommodated, space is not take up, it is easy to use；

(3) the utility model blade both ends ruler handle is the protractor of two semicircles, 180 ° of scales, can draw 0 ° -360 ° Random angle in angle, two ruler handles are respectively positioned on blade lower surface, can cause in this way because one side has ruler handle to avoid blade Angled with drawing paper, there is error in caused drawing.

The utility model is further improved on the basis of existing T-square so that the function of T-square is more complete Face.
