Problems solved by technology

[0004] When fixing the paper, because there is a gap between the paper and the bottom plate, when the air is flowing, the middle of the paper is raised, and when the graphics are drawn, deviations are prone to occur, and when the paper is placed At the same time, due to the relatively fixed space, the paper is wrinkled, which affects the drawing effect. Therefore, a graphic drawing device for analyzing the international trade, financial and economic situation is proposed to solve the problem.

Embodiment 1

[0034] A graphic drawing device for analysis of international trade, financial and economic situation, including a bottom plate 1, a fixed bar 2 and a moving frame 3, the top of the bottom plate 1 is fixedly connected to the front and rear sides of the fixed bar 2, and a moving frame is arranged between the two fixed bars 2 3.

[0035] A thin metal plate 101 is arranged on the inside of the base plate 1, and a slide rail 201 is provided on the side where the fixing bar 2 is located at the center of the base plate 1. A slide block 202 is embedded in the slide rail 201, and the bottom end of the slide block 201 is located on the slide rail. 201 is fixedly connected with spring 1 205, the end of spring 1 205 away from slider 1 202 is fixedly connected with slider 2 204, slider 2 204 is located below slider 1 202, and slider 2 204 is embedded in the slide rail 201 A telescopic rod 203 is fixedly connected to the outer side of the spring one 205 between the slider one 202 and the s...

Embodiment 2

[0039] The difference between this embodiment and Embodiment 1 is that the end of the slider two 204 away from the slide rail 201 is fixedly connected with the moving frame 3 , the bottom of the moving frame 3 is provided with a fixed frame 301 inside, and the bottom of the fixed frame 301 is fixed A second spring 302 is connected, and a moving plate 304 is fixedly connected to the side of the second spring 302 away from the fixed frame 301 .

[0040] A fixed block 303 is fixedly connected between the moving plate 304 and the inner bottom of the moving frame 3 , and a sphere 305 is arranged at the bottom of the moving frame 3 below the moving plate 304 .

[0041] Wherein: when the drawings that need to be drawn are placed between the bottom surface of the moving frame 3 and the base plate 1, when the moving frame 3 moves on the base plate 1, the ball 305 is rolling, so that the frictional force between the moving frame 3 and the surface of the paper is reduced, reducing the imp...

Embodiment 3

[0043]Compared with Embodiment 1 and Embodiment 2, this embodiment differs in that: the inner bottom end of the moving frame 3 is connected with a briquetting block 1 through a bearing, and the end of the briquetting block 4 away from the moving frame 3 is connected with a briquetting block 2 through a bearing. 5. There is a moving block 501 inside the first briquetting block 4 and the second briquetting block 5, the tops of the first briquetting block 4 and the second briquetting block 5 are provided with through holes, the top of the moving block 501 is arc-shaped, and the The outer surface is tangent to the inner surface of the through hole provided at the top of briquetting block one 4 and briquetting block two 5, the bottom end of moving block 501 is fixedly connected with moving bar 502, and the bottom end of moving bar 502 runs through briquetting block two 5 and briquetting block The bottom end of two 5 is connected with spring three 507, the lower side of moving bar 50...

Abstract

The invention provides an international trade financial economic situation analysis graph drawing device which comprises a bottom plate, fixed strips and a movable frame. The fixed strips are fixedly connected to the front side and the rear side of the top end of the bottom plate, and the movable frame is arranged between the two fixed strips. According to the international trade financial economic situation analysis graph drawing device, a bearing is connected between a fixed rod and the interior of a second pressing block, the distance from the bearing to a movable rod is larger than the distance from the bearing to a transverse rod, a metal sheet can generate magnetic field attraction with a magnet, the metal sheet can be made of iron, when a first pressing block and the second pressing block are moved out of the movable frame and moved to the needed positions, a moving block and the movable rod move towards the upper portion of the first pressing block and the upper portion of the second pressing block through the elastic force of a third spring at the same time, through the lever principle, the magnet moves downwards and gets close to the metal sheet, a magnetic field is formed, accordingly, suction force is generated, the moving positions of the first pressing block and the second pressing block are fixed, paper is fixed, and graph paper drawing is facilitated.

Description

technical field [0001] The invention relates to the field of household technology, in particular to a graphic drawing device for analyzing international trade, financial and economic situation. Background technique [0002] With the overall development of our country's national economy and social undertakings, the level of international trade and financial economy has gradually improved. In order to facilitate the analysis of the economic situation, we will use the drawing device to analyze on the drawings. When drawing, the corners of the drawings It will warp, which will cause the drawing paper to wrinkle, resulting in lower drawing efficiency. [0003] Among them, after searching, it is found that there is a patent No. CN202020339789.4, a financial and economic situation analysis graph drawing device. The bit shell is used to limit the position, so as to limit the position of the ruler plate, avoiding the phenomenon of deviation from the drawing area due to left and righ...
