s6: the buffer springs (23) in the S5 can play a role in buffering, when a child lies prone on the desk plate (15) unintentionally, impact force drives the desk plate (15) to move downwards and compress the buffer springs (23), the desk plate (15) drives the four vertical rods (20) to slide downwards in the corresponding inner tubes (19) respectively, and the buffer springs (23) can relieve the received impact force and reduce the damage to the child;
s7: u-shaped frame (1) is through four stabilizer blades (16) and four slot (30) and the fixed mode of table (15) cartridge, when can prevent level and smooth, also makes things convenient for follow-up lecturer to remove U-shaped frame (1) from table (15) fast, and U-shaped frame (1) drives stabilizer blade (16) and separates with corresponding slot (30), and table (15) can be used as liftable formula desk this moment.
