[0028] The storage box 10 is provided with a second storage cavity and three first storage cavities from right to left. When working, drawing tools such as pens, erasers and rulers can be placed in the three first storage cavities, and blank paper can be placed in the second storage cavity for easy access. Since the lighting lamp 6 is placed in the lamp support frame 4, the lighting lamp 6 can be removed and placed in the first storage cavity for storage when not in use.

[0029] The rear end of the tool box 1 is fixedly connected with a support tube 20, and a sealing plug 2 is sleeved inside the support tube 20. During work, the finished drawings can be rolled into a paper tube and placed inside the support tube 20 for storage.

[0030] The front end of the end cover 3 is rotatably connected with a card plate 5, and a rectangular hole 22 is provided on the front end surface of the card plate 5. The front end of the tool box 1 is fixedly connected with an ear plate 7 and a support seat 9.

The insides of the two support plates 12 are slidably connected with the insertion rod 19. The insertion rod 19 is connected to the end cover 3 through the second slot 13. The end of the insertion rod 19 away from the tool box 1 is fixedly connected to the circular plate 17. A spring 18 is arranged between the circular plate 17 and the support plate 12. The spring 18 is sleeved on the circumferential surface of the insertion rod 19. One end of the spring 18 is fixedly connected to the circular plate 17, and the other end of the spring 18 is fixedly connected to the support plate 12. During operation, the end cover 3 is rotated along the hinge until the end cover 3 is at a certain angle, the support plate 12 is rotated, and the circular plate 17 is pulled away from the tool box 1, driving the insertion rod 19 to move until the end of the insertion rod 19 is completely inserted into the support plate 12, and the spring 18 is stretched. Then, by continuously adjusting the position of the insertion rod 19 to correspond to the position of the second slot 13, the insertion rod 19 is driven to reset in the direction of the end cover 3 under the action of the spring 18 and inserted into the second slot 13. At this time, the support plate 12 can stably support the end cover 3 at a certain angle, which is convenient for the staff to draw on the end cover 3. At the same time, the end cover 3 is opened, which is convenient for taking tools inside the storage box 10.

[0032] The left and right end surfaces of the tool box 1 are both provided with first slots 11, and the insertion rod 19 is connected to the tool box 1 through the first slots 11. During operation, when the support plate 12 no longer supports the end cover 3, the support plate 12 is rotated, and the insertion rod 19 is driven to rotate until the position of the insertion rod 19 corresponds to the position of the first slot 11, so that the insertion rod 19 is inserted into the first slot 11, so that the support plate 12 is stably connected to the tool box 1 under the cooperation of the insertion rod 19 and the first slot 11.

[0033] The lamp support frame 4 includes an L-shaped rod and a support shell. The support shell is fixedly mounted on one end of the L-shaped rod away from the end cover 3.

The illuminating lamp 6 is a rechargeable LED illuminating lamp 6 tube. The charged illuminating lamp 6 can be placed in the support shell. The light emitted can illuminate the end cover 3 and its surroundings through the support shell, so that it is convenient for workers to place drawings and draw on the end cover 3 when working outdoors at night.

[0034] Working principle:

[0035] When in use, place the tool box 1 at the designated location, first pull the latch 8 to disengage it from the ear plate 7 and the card plate 5, then rotate the card plate 5 to move it away from the ear plate 7, and then rotate the end cover 3 along the hinge until the end cover 3 is at a certain angle, pull the circular plate 17 in the direction away from the tool box 1, and drive the insertion rod 19 to gradually disengage from the first slot 11. At the same time, the spring 18 is stretched until the insertion rod 19 is completely disengaged from the first slot 11, and then rotate the support plate 12 to drive the insertion rod 19 to move until the position of the insertion rod 19 corresponds to the position of the second slot 13. Under the action of the spring 18, the insertion rod 19 is driven to move in the direction of the end cover 3 to reset and insert it into the second slot 13. At this time, the support plate 12 can stably support the end cover 3 at a certain angle, and then the staff can use tools on the end cover 3 to draw. When working outdoors at night, first rotate the threaded fastening rod 16 so that it moves while rotating along the fixing seat 21 until the threaded fastening rod 16 is disengaged from the fourth slot 15, and then rotate the lamp support frame 4 until the support shell in the lamp support frame 4 is located at the front end of the end cover 3, and the lamp support frame 4 and the end cover 3 are in a vertical state. At the same time, when the threaded fastening rod 16 corresponds to the position of the third slot 14, the threaded fastening rod 16 can be rotated to insert it into the third slot 14. At this time, the lamp support frame 4 can be stably connected to the end cover 3, and then the lighting lamp 6 can be placed in the lamp support frame 4, and the lighting lamp 6 can be used to illuminate the end cover 3 and its surroundings, so as to facilitate drawing by the staff.
