After the limit tooth plate 233 moves downward, it can be separated from the rack 21. At this time, the bottom storage drawer 11 can be pulled out and moved forward, and the storage drawer 11 can be pulled out. At the same time, the safe 61 can be lifted up through the transmission mechanism 3. In this process, it is only necessary to loosen the pull ring, and the limit spring 232 can be reset to drive the limit tooth plate 233 and the gear 22 to engage with each other and limit. The engagement of the limit tooth plate 233 and the gear 22 can cause the rack 21 and the gear 22 to fit and limit each other, thereby playing a certain braking and limiting role, so that the bottom storage drawer 11 and the safe storage assembly 6 can stop in a suitable position for use. At the same time, after use, it is only necessary to pull the half pull ring 235 to drive the pulling shaft 234 The limiting tooth plate 233 is driven to disengage from the teeth of the gear 22, and the traction of the hanging rope 33 can cause the bottom slide plate 8 to reset, so that the storage drawer 11 at the bottom of the storage box 1 can have the function of automatic reset. In addition, during the overall use of the device, the window 9 and the cover plate 10 are set, so that the window 9 can be shielded during use, which can play a good shielding function. In addition, a screen 15 is set during its use, which can be shielded by the screen 15. In addition, the power strip 16 is set to facilitate the power supply of electrical appliances on the office desk, which is convenient for use. At the same time, the placement plates 18 and enclosures 19 with equal spacing can facilitate the placement of items needed during office work and personal items, which can improve the convenience of the overall use of the device. For example, in daily office work, the automatically reset storage drawer 11 and the rich storage settings can improve work efficiency and make the office environment more tidy and orderly.
