Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 4, the present invention provides a technical solution: a plotting tool for economic management comprises an inner box 3 for placing the plotting tool, an outer box is sleeved outside the inner box 3 and comprises a bottom box 1 and two sets of box covers 2 hinged at the upper end of the bottom box 1, the two sets of box covers 2 can be overturned for 0-180 degrees along the edge of the bottom box 1 and can be freely combined with the bottom box 1 to form a movable plotting board, when in use, the two sets of box covers 2 are overturned for 180 degrees outwards along the hinged edge and form a cuboid structure with the bottom box 1, then the inner box 3 provided with the plotting tool is taken out and placed aside, then the combined bottom box 1 and the box cover 2 are overturned for 180 degrees integrally to form a simple plotting platform, so that a user can find a bottom plate for plotting draft at any time during plotting, the plotting efficiency is improved, and the purpose of widening the area of the plotting platform is achieved by arranging the two sets of box covers and the bottom box to be a freely combined structure, the use of the user is convenient.

As shown in fig. 1 and 3, an elastic support assembly is arranged at the lower end inside the bottom case 1, the inner case 3 is placed in the bottom case 1 and is arranged at the upper end of the elastic support assembly, and handles 11 are movably arranged at the tops of the mutually close ends of the two sets of case covers 2; the handle 11 is a door-shaped handle, and the case cover 2 is provided with a through hole which is in sliding fit with the handle 11. Through setting up door shape handle 11, can be convenient for take to the device is holistic, portable.

As shown in fig. 4, the elastic support assembly includes a storage plate 4, a column 5, a driving plate 6, a first spring 7, a wedge-shaped block 8, a second spring 9 and a positioning block 10, and the storage plate 4 is slidably mounted in the inner cavity of the bottom case 1 and abuts against the inner case 2. The rectangular cavity has been seted up on the diapire of under

casing

1, and 5 one end fixed connection of stand

put thing board

4, and 5 other ends of stand stretch into rectangular cavity and fixed connection drive plate 6, the first spring 7 of bottom fixed connection of drive plate 6. The drive plate is the forked tail shaped plate, and the both ends of drive plate all are contradicted and are connected with a set of wedge 8, and two sets of wedge 8 carry out sharp phase motion in the rectangle cavity.

As shown in fig. 2 and 3, the second spring 9 is disposed at the upper end of the positioning block 10, one end of the second spring is fixedly connected to the wedge block 8, and the other end of the second spring is fixedly disposed on the side wall of the rectangular cavity. The spring constant of the first spring 7 is greater than the spring constant of the second spring 9.
