Embodiment 1

[0032] as attached figure 1 to attach Figure 6 Shown:

[0033] The invention provides a tool for drawing in economical management, the structure of which comprises a swivel body 1 and a straightedge 2, and the swivel body 1 runs through the inside of the straightedge 2.

[0034] The ruler 2 includes a ruler x1, a fixed angle x2, a shift x3, an arrival x4, and a marking block x5. The channel x4 has an inner groove and is flexibly connected, and the channel x3 is embedded in the inside of the ruler x1.

[0035] Wherein, the scribed block x5 includes an internal fixing channel 001, a support plate 002, a pendulum body 003, a stippling head 004, and a rubber support bottom 005. The internal fixing channel 001 is embedded in the support plate 002, and the support plate 002 is The surface is equipped with a rubber support bottom 005, and the dot painting head 004 and the pendulum body 003 are in clearance fit. The dot painting head 004 has a triangular structure, and the rubber ...

Embodiment 2

[0042] as attached Figure 7 to attach Figure 9 Shown:

[0043] Wherein, the arrival path x4 includes a uniform force point m1, a clamping angle m2, and an empty channel m3, and the empty channel m3 is installed between the clamping angles m2, and the clamping angle m2 fits with the uniform force point m1, and the uniform force point m1 is uniformly distributed in the horizontal direction, and when the clamping angle m2 is clamped at a fixed position, it will drive the overall limit and buffer itself.

[0044]Wherein, the clamping angle m2 includes a hard block 41, a pocket ball 42, a side corner 43, and a middle corner 44, the pocket ball 42 is embedded inside the hard block 41, and the side corner 43 is against the outer surface of the middle corner 44, so The pocket ball 42 is a spherical structure, the side contact angle 43 is provided with two, the described pocket ball 42 evenly extends the force-bearing part, the middle angle 44 consolidates the power at the middle e...

Abstract

The invention discloses a tool for economic management mapping. The tool structurally comprises rotary bodies and a ruler. The rotary bodies penetrate into the ruler. The ruler comprises a partition ruler, a constant angle, a movable way, an abutting way and scribing blocks. The constant angle and the partition ruler are of an integrated structure, the rotary bodies of the tool can move along themovable way, the partition ruler at the lower end is in a horizontal direction, the inner wall of the abutting way is supported by a supporting plate, a linkage portion is retarded through an externally-expanding arc arranged inside, when the linkage portion bears force, the constant angle is fixed onto a starting point, when same oblique lines need to be drawn, a fixed point of the ruler is fixed, the tool is moved out to another map for copying, overall bearing force is unified through force unifying points in clamping angles of the tool, side abutting angles and a middle angle are clamped into an inner fixed way, an abutting portion is moved at the position limited to a certain degree, contact between an object and the side abutting angles is buffered to a certain degree, and in the moving process in a limited space, certain softness force exists between the contact portions.

Description

technical field [0001] The invention belongs to the field of school supplies, and more specifically relates to a tool for economic management drawing. Background technique [0002] In economic management, there are various forms of expression for the tables and graphs that need to be drawn. The graphs that will be drawn based on the data need to be accurate and precise to minimize errors, and the required tables and graphs are drawn using fixed-form tools. [0003] Based on the inventor's discovery above, existing economic management mapping tools mainly have the following deficiencies, such as: [0004] When it is necessary to draw a straight line with the same slope in two large graphs of x and y axes, it will be necessary to re-fix the punctuation point and draw with the positioning ruler, and the errors in the process of re-drawing will increase, which will affect the original Effect. [0005] There is therefore a need to propose a tool for economic management mapping....
