This utility model is further arranged to: the length of slide block is equal to the length of dovetail groove.
This utility model is further arranged to: the length of slide block is less than the length of dovetail groove, and the end of described dovetail groove is provided with limited block.
This utility model is further arranged to: the sidewall of set square a is provided with the containing cavity of storage slide block.
This utility model is further arranged to: the sidewall of containing cavity is provided with the spring of connection sliding block.
This utility model is further arranged to: spring and containing cavity diapire are 90 ° of settings.
This utility model is further arranged to: spring and containing cavity diapire are 45 ° of settings.
Compared with prior art, there is advantages below in this utility model multi-angle set square:
1, both set squares original are combined into one piece, reduce volume；
2, the risk that one of which set square is lost is avoided；
3, the picture demand of 15 °, 30 °, 45 °, 60 °, 90 °, 135 ° multi-angles is provided.

Detailed description of the invention
Referring to figs. 1 through Fig. 6, this utility model ruler embodiment is described further.
Embodiment one
As shown in Figure 1, a kind of multi-angle set square, set square a1 and the set square b2 with 15 °, 30 °, 135 ° three angles including isosceles right angle, the length of the common oblique side 3 of 15 ° of set square b2 and 135 ° is equal with the length of the hypotenuse 4 of set square a1, the sidewall of common oblique side 3 is provided with dovetail groove 5, the sidewall of the hypotenuse 4 of set square a1 is provided with the slide block 6 coordinating dovetail groove 5.
Embodiment two
A kind of multi-angle set square, including the set square a1 and the set square b2 with 15 °, 30 °, 135 ° three angles at isosceles right angle, the length of the common oblique side 3 of 15 ° of set square b2 and 135 ° is equal with the length of the hypotenuse 4 of set square a1.Being provided with dovetail groove 5 on the sidewall of common oblique side 3, dovetail groove 5 length is equal to the half of common oblique side 3 length, and one end of dovetail groove 5 is run through the sidewall of set square a1 and arranged.Being provided with the slide block 6 coordinating dovetail groove 5 on the sidewall of the hypotenuse 4 of set square a1, the length of slide block 6 is equal with dovetail groove 5 length.
This example structure is simple, easy to operate.The dovetail groove 5 of half is arranged can anti-limited slip block 6 excessive slip, it is possible to play positioning action, it is prevented that dislocation (namely playing the effect of limited block 7) after set square a1 and set square b2 splicing.
Embodiment three
As in figure 2 it is shown, a kind of multi-angle set square, including the set square a1 and the set square b2 with 15 °, 30 °, 135 ° three angles at isosceles right angle, the length of the common oblique side 3 of 15 ° of set square b2 and 135 ° is equal with the length of the hypotenuse 4 of set square a1.Being provided through dovetail groove 5 on the sidewall of common oblique side 3, the one end of dovetail groove 5 is provided with limited block 7.Being provided with the slide block 6 coordinating dovetail groove 5 on the sidewall of the hypotenuse 4 of set square a1, sidewall is additionally provided with the containing cavity 8 of storage slide block 6, the axial both ends of containing cavity 8 are closed by elastomeric objects.
Embodiment four
If Fig. 3 is to shown in 6, a kind of multi-angle set square, including the set square a1 and the set square b2 with 15 °, 30 °, 135 ° three angles at isosceles right angle, the length of the common oblique side 3 of 15 ° of set square b2 and 135 ° is equal with the length of the hypotenuse 4 of set square a1.The sidewall of common oblique side 3 is provided through dovetail groove 5, the sidewall of the hypotenuse 4 of set square a1 is provided with the slide block 6 coordinating dovetail groove 5.Being additionally provided with the containing cavity 8 of storage slide block 6 on hypotenuse 4 sidewall of set square a1, the diapire of containing cavity 8 is provided with the spring 9 of connection sliding block 6.
Preferably, the quantity of spring 9 is some, connects better effects if, and when making set square a1 and set square b2 splicing, structural strength is higher, more firmly.
Spring 9 and containing cavity 8 diapire are 90 ° of settings, and set square a1 is higher with the spliced structural strength of set square b2.
Spring 9 and containing cavity 8 diapire are 45 ° of settings, and set square a1 is with set square b2 splicing, and spring 9 stress is little, can extend the service life of spring 9.
