Abstract

A chair seat combined with two armrests, each comprising crossbar with first toothed structure, is provided. Chair seat includes base and clamping devices. Base comprises armrest slot and mounting holes, where armrest slot accommodates crossbar and mounting holes are connected to armrest slot. Additionally, each of two clamping devices, installed in the two mounting holes, includes mounting base, clamping element, operating component, and transmission element. Mounting base is installed and fixed in mounting hole, with one side of mounting base having installation groove. Clamping element is installed in installation groove and has second toothed structure facing first toothed structure. Operating component is positioned on other side of mounting base relative to installation groove. Transmission element connects clamping element and operating component. Operating component is adapted to drive transmission element, causing clamping element to move towards and clamp crossbar, thus enabling second toothed structure to engage closely with first toothed structure.
