Movable cavities 2 are provided on both mounting brackets 11. Through grooves 21 are provided on opposite sides of the two movable cavities 2. A connecting rod a22 is provided inside the movable cavity 2. Locking rods 23 are fixedly connected to both ends of the connecting rod a22. Springs 24 are sleeved on both ends of the connecting rod a22. A pressure plate 25 is provided inside the through groove 21. One side of the pressure plate 25 is connected to the connecting rod a22. Two plug-in cylinders 26 are fixedly connected to opposite sides of the two mounting brackets 11. Through holes for the locking rods 23 to move are provided on one side of the movable cavity 2. These through holes communicate with the interior of the plug-in cylinders 26. Two plug-in blocks 27 are fixedly installed at the bottom of the tabletop 12. Each plug-in block 27 has a locking groove 28.

[0033] When installing the tabletop 12, push the pressure plates 25 on both sides to opposite sides. The pressure plates 25 move in the through groove 21. The pressure plates 25 push the connecting rod a22 to move inside the movable cavity 2. The connecting rod a22 drives the two locking rods 23 to retract into the through hole. At the same time, the spring 24 is compressed and stored energy. Then, insert the plug block 27 at the bottom of the tabletop 12 into the plug cylinder 26. Then, release the pressure plate 25 and the spring 24 to release the elasticity. Push the locking rod 23 out of the through hole and into the locking groove 28. And drive the connecting rod a22 and the pressure plate 25 back to the initial position to install and fix the tabletop 12. When disassembling the tabletop 12, push the pressure plates 25 on both sides to opposite sides to retract the locking rod 23 into the through hole and release the fixation of the plug block 27. In this way, the tabletop 12 can be quickly installed and disassembled.
