[0031] As Figures 1-11 shown, in this embodiment, a toolbox for construction engineering technology includes a box body 1. The box body 1 has an open top and is used to store writing tools and paper. A grip 12 is hinged in the middle of the front end of the box body 1 for convenient hand-held carrying. A sliding cover 2 that slides horizontally is connected to the top of the box body 1, which is convenient for opening the box body and also allows a person to sit on the sliding cover 2. The end of the sliding cover 2 is fixed to the box body 1 through a torsion pin 3 on the box body 1. The torsion pin 3 can rotate to position or release the positioning of the sliding cover 2. An L-shaped plate 4 is fixed inside the box body 1. A folding plate device storage groove 5 is provided between the L-shaped plate 4 and the box body 1. A folding plate device 6 is folded and placed in the folding plate device storage groove 5. The folding plate device 6 includes a main rod 61, a telescopic rod 62, a spring positioning pin 63, a writing board 64, a rotating shaft 65, a lower support rod 66, a limiting plate 67, and an upper support rod 68. One end of the main rod 61 is hinged to the inner side plate of the box body 1 through a hinge, and the hinged position is below the sliding cover 2 to avoid affecting the sliding cover 2. The other end is provided with a freely telescopic telescopic rod 62. The telescopic rod 62 is positioned with the main rod 61 through a spring positioning pin 63. The end of the telescopic rod 62 is connected to a writing board 64 through a rotating shaft 65, and the writing board 64 is fixed to the rotating shaft 65. One end of the lower support rod 66 is also hinged to the inner side plate of the box body 1 through a hinge. A limiting plate 67 is fixed to the outer side surface of the other end of the lower support rod 66, and this end is hinged to one end of the upper support rod 68. The other end of the upper support rod 68 is hinged to the outer wall of the main rod 61. By folding, the volume is reduced, and the writing board 64 is stored inside the box body 1 for easy carrying. It can also be unfolded and fixed to the writing board 64, which is convenient for a person to sit on the sliding cover 2 and write on the writing board 64, increasing the comfort and practicality of the person's writing.

[0032] Specific embodiments, such as Figure 4 and Figure 5As shown, when the telescopic rod 62 is extended to the longest distance, it is fixed by the spring positioning pin 63. To increase the height of the writing board 64, when the main rod 61 is lifted, the lower support rod 66 and the upper support rod 68 rotate. When they rotate to be parallel, they continue to rotate until the limit plate 67 contacts the upper support rod 68, making the lower support rod 66 and the upper support rod 68 unable to rotate further. Then, press down the main rod 61 so that the lower support rod 66 and the upper support rod 68 play a role in supporting the main rod 61. At this time, the main rod 61 rotates close to 45°, and the writing board 64 reaches the optimal writing position. The writing board 64 can be fixed to the horizontal angle by rotating with greater friction, which is convenient for writing.

[0033] Furthermore, the top of the telescopic rod 62 includes a hexagonal groove 621, a hexagonal groove spring 622, a hexagonal ring 623, an end plate 624, and engaging teeth 625. The outer side of the telescopic rod 62 connected to the rotating shaft 65 is provided with a hexagonal groove 621. A hexagonal groove spring 622 is arranged in the hexagonal groove 621. The hexagonal ring 623 slides along the axial direction of the rotating shaft 65 and is supported by the hexagonal groove spring 622 when sliding in the hexagonal groove 621. The end plate 624 is located outside the hexagonal ring 623, and the end plate 624 is fixed to the end of the rotating shaft 65. Engaging teeth 625 that fit each other are respectively fixed on the opposite sides of the hexagonal ring 623 and the end plate 624 to fix the rotation angle of the positioning rotating shaft 65. When the writing board 64 freely adjusts the angle, by pressing the hexagonal ring 623, the engaging teeth 625 are disengaged from the fit, and the writing board 64 can be rotated and then positioned, increasing the bearing capacity of the writing board 64 and avoiding easy rotation.

[0034] Furthermore, bundling devices 13 are arranged on both sides inside the box body 1. The bundling devices 13 include fixing columns 131, top plates 132, fixing column springs 133, pressing plates 134, and pressing strips 135. The left and right fixing columns 131 are respectively perpendicular to the inner bottom surface of the box body 1 and can be connected by a bolt fixing method. The top of the fixing column 131 is fixed with a top plate 132. A fixing column spring 133 is sleeved on the fixing column 131. The pressing plate 134 is axially slidably connected along the fixing column 131 and is located below the fixing column spring 133. A pressing strip 135 is connected between the left and right pressing plates 134, and the pressing strip 135 is an elastic elastic band. The elastic pressing strip 135 can bind articles or papers. If the articles or papers are higher or thicker, pull up the pressing strip 135 to compress the fixing column spring 133, increasing the space below the pressing strip 135, facilitating the binding of articles or papers and preventing them from being scattered inside the box body 1.

[0035] Specifically, horizontal guide grooves 11 are formed at the top opening of the box body 1 on the left and right. Guide bars 21 are fixedly arranged on the left and right of the sliding cover 2.
