The adjusting screw 30 drives the adjusting block 32 and the second connecting rod 33 to move to the side away from the adjusting knob 31. The second connecting rod 27 drives the first connecting rod 26 to rotate upward synchronously, and the first connecting rod 29 moves in the moving groove 28, thereby moving the support plate 24 upward for lifting. After adjusting to the appropriate height, it is convenient for the staff to perform engineering cost calculation operations, which improves the convenience of use. When recycling, you only need to turn the adjusting knob 31 in the opposite direction.

[0033] In summary, when the entire device is in use or running: when the cover plate 3 and the box body 2 are buckled together, the insertion rod 7 of the cover plate 3 is inserted into the insertion groove 9 of the fixed block 8, and the top surface of the clamping block 12 is an inclined surface, thereby squeezing the clamping block 12 and the movable plate 11 to move to both sides, and the movable plate 11 squeezes the movable spring 14, and the insertion rod 7 continues to move downward and compresses the clamping plate 15 and the clamping spring 16. When the clamping block 12 is aligned with the clamping groove 13, the movable plate 11 drives the clamping block 12 to extend into the clamping groove 13 under the elastic force of the movable spring 14, thereby pressing the insertion rod 7 is fixed in position, and the cooperation of the guide block 17 and the guide groove 18 is convenient for guiding the movable plate 11 when it moves. When removing the cover plate 3, the reset rod 21 is squeezed upward, and the reset rod 21 drives the reset block 20 to move upward and stretch the reset spring 22, so that the reset block 20 squeezes the movable block 19 to both sides, and then the movable plate 11 moves to both sides, driving the clamping block 12 to leave the clamping groove 13. At this time, the clamping plate 15 drives the insertion rod 7 to lift and move upward under the elastic force of the clamping spring 16, which facilitates the removal of the cover plate 3 and improves the practicality of the auxiliary box 1.

[0034] Place the computer and recording board on the limiting ring 6 of the support plate 24. When using it at the construction site, turn the adjusting knob 31, and the adjusting knob 31 drives the adjusting screw 30 to rotate. The adjusting screw 30 drives the adjusting block 32 and the second connecting rod 33 to move to the side away from the adjusting knob 31.
