Description

technical field [0001] The invention relates to the technical field of furniture, in particular to a height-liftable child seat. Background technique [0002] Seats are commonly used home and teaching furniture. Traditional seats have a fixed height, which cannot meet the needs of different heights, and the use comfort is poor. Later, height-adjustable seats appeared, which can effectively meet the needs of different heights. Improve the comfort of use. At present, the commonly used lifting mechanism for seats is that a number of fixing holes are opened in the vertical direction on the feet, and the seat table is fixed in the fixing holes of different heights by bolts to achieve height adjustment. Only tools can be assembled and disassembled, otherwise the stability of the connection cannot be guaranteed, and the seat is prone to shaking and falling apart. Contents of the invention [0003] The technical problem to be solved by the present invention is the deficiency of ...
