Preferably, a variety of mechanisms are formed by the right curved rule 3, the left curved rule 4, the fixing plate 8, the threaded column 16, the fixing groove 17 and the bolt 15, when a user wants to draw a curve, the user can draw a required curve through the curved rules (including the right curved rule 3 and the left curved rule 4), when the user wants to draw a straight line, the user can draw a required straight line through the straight rule 2, when the user wants to draw an angle, the user needs to firstly take the fixing plate 8 to drive the threaded column 16 out of the corresponding fixing groove 17 at the bottom of the connecting column 7, then the left curved rule 4 (or the right curved rule 3) is loosened from the connecting column 7 through the threaded column 16, then the user turns the loosened left curved rule 4 (or the right curved rule 3) upwards along with the hinge column 5, wherein when the left curved rule is turned upwards, the user can adjust the rotating angle of the left curved rule 4 (or the right curved rule 3) according to the angle scale 14 on the front side of the hinge column 5, and the angle that the perpendicular that face of left side curvilinear rule 4 (or right curvilinear rule 3) and right curvilinear rule 3 (or left curvilinear rule 4) perpendicular that face formed can the person of facilitating the use draw required angle, so be provided with various mechanism in 1 department of curvilinear rule main part, can the person of facilitating the use draw required curve, straight line and angle to make 1 using-way of curvilinear rule main part more diversified, also the person of facilitating the use uses a curvilinear rule main part 1 just can draw the figure of multiple difference, thereby has improved greatly the utility model discloses a variety.

The working principle is as follows:

firstly, when a user draws a curve, the user firstly drives the connecting columns 7 to move towards two sides of the sliding rail 11 by the fixing plates 8 on two sides, the fixing plates 8 on two sides can drive the left curve ruler 4 and the right curve ruler 3 to rotate identically through the hinge column 5 when moving, meanwhile, the user can also pull out the tape measure 13 from the tape measure box 6 and insert the tape measure 13 into the fixing opening 9 by holding the clamping column 12 with hands, and the user can know the unfolded angles of the left curve ruler 4 and the right curve ruler 3 according to the size of the tape measure 13, so that the user can know the unfolded angles of the left curve ruler 4 and the right curve ruler 3 more accurately, the user can draw the same two pictures quickly, and the condition that the analysis result is inaccurate due to errors generated in the analysis process of the user is avoided;

then, when a user wants to straighten the tape 13, the user can pull the tape 13 out of the bottom of the tape box 6, then hold the clamping column 12 by hand to drive the tape 13 to be inserted into the fixing port 9 of the ruler 2, and because the size of the fixing port 9 is consistent with that of the clamping column 12, when the clamping column 12 is inserted into the fixing port 9, the tape 13 is integrally straight, so that the situation that the numerical value is inaccurate due to inclination is avoided;

then, when the user takes the curve ruler out of the corresponding connecting column 7, the user can take the curve ruler out of the corresponding connecting column 7 from one side of the clamping column 19 by holding the bolt 15 with the hand, and then the other side of the top of the connecting column 7 with the clamping column 19 is unfolded towards the other side, and the clamping column 19 is driven to take out of the curve ruler while the connecting column is unfolded, so that the user can conveniently separate the curve ruler from the connecting column 7;

next to, when the user will draw a curve, the required curve can be drawn through the curved ruler (including the right curved ruler 3 and the left curved ruler 4), and when the user will draw a straight line, the required straight line can be drawn through the straight ruler 2, and when the user will draw an angle, the user needs to take out the fixing plate 8 to drive the threaded column 16 from the corresponding fixing groove 17 at the bottom of the connecting column 7, then the left curved ruler 4 (or the right curved ruler 3) is loosened from the connecting column 7 through the threaded column 16, then the user turns over the loosened left curved ruler 4 (or the right curved ruler 3) upwards along with the hinge column 5, wherein when the left curved ruler is turned over in a rotating way, the user can adjust the rotating angle of the left curved ruler 4 (or the right curved ruler 3) according to the angle scale 14 on the front side of the hinge column 5, and the angle formed by the vertical side of the left curved ruler 4 (or the right curved ruler 3) and the vertical side of the right curved ruler 3 (or the left curved ruler 4) can be convenient for the user to draw the The required angle, so the various mechanisms are arranged at the curve ruler main body 1, which is convenient for users to draw required curves, straight lines and angles, thereby the use mode of the curve ruler main body 1 is more diversified, and the users can draw various different drawings by using one curve ruler main body 1, thereby the diversity of the utility model is greatly improved;

finally, when the user will use ruler 2 to draw the straight line, the user can place ruler 2 in the place that will draw the line, then draw the line in there being ruler scale 10 place along ruler 2, and because of about ruler 2 and ruler scale 10 department all thicker, so the user can not produce the condition of not placing the level because of the curved rule when drawing the straight line, also convenient to use person can be steady draw out so required length along ruler scale 10 on ruler 2 simultaneously, this kind of sports statistics is with folded cascade curved rule's theory of operation.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
