[0002] A child seat is a safety seat specially designed for children and is suitable for children from 2 to 14 years old.

[0003] Since children's bodies are constantly developing while using the seat, their height will gradually increase. Therefore, in order to be suitable for children of different heights, footrests are usually added to the telescopic seat to increase the comfort of children. However, since children's legs are of different lengths, the height of the footrest needs to be adjustable. The existing footrest adjusts the height of the footrest through the cooperation of the n-shaped frame, the toggle wheel, the screw and the opening. However, when adjusting, it is necessary to put the hand into the bottom of the seat support seat and turn the toggle wheel, which is inconvenient to operate. In addition, the child cannot operate it while sitting on the seat, and it is impossible to judge whether the adjusted height is appropriate when operating on the ground, which increases the time of the entire adjustment. In addition, the cooperation between the downslide and the downslide mouth makes the height of the footrest rising and falling shorter, which cannot fully meet the needs of children of different heights. After searching, it was found that the technical solution provided by the utility model with application number 202121643173.7 also has the above-mentioned problems. Utility Model Content
