This creation provides a kind of grass trimmer tool-apron structure,It is arranged on the base a break bar,Two elastomer blocks,A connection piece,At least two elastic slices and a cutter,The cutter connects through the elastomer block group of both ends and fixed what pedestal,It can ensure that cutter and break bar maintain setting state,Smoothly weeds are cut off with generating good shearing,And the elastic prestressing of the elastomer block provides the ability that the cutter carries out some displacement,The situation for avoiding cutter and break bar from excessively resting against and break bar being caused to be difficult to turn； In addition,Through in the cutter bottom surface, the elastic slice is set,Further ensure that cutter and break bar maintain setting state,Avoid the cutter affixed with elastomer block in elastic block relaxation Hou,The knife edge is separate with break bar blade and influences the problem of cutting shearing.本創作提供一種割草機刀座結構，其係在基座上設置一刀輪、二彈性塊、一連接件、至少二彈片及一切刀，該切刀透過兩端和固設於基座的彈性塊組接，可確保切刀和刀輪維持靠置狀態，以產生良好剪力順利將雜草切斷，且該彈性塊的彈性預力提供該切刀進行些許位移之能力，避免切刀和刀輪過度靠置而導致刀輪難以旋動之狀況；此外，透過在該切刀底面設置該彈片，進一步確保切刀和刀輪維持靠置狀態，避免與彈性塊固接的切刀在彈性塊鬆弛後，刀鋒與刀輪刀片遠離而影響切割剪力之問題。
