很多人都喜欢吃核桃,核桃美味又营养,但剥壳很麻烦。有人用夹子,有人干脆用嘴咬,都不方便。所以我想发明一个自动剥壳机,只要你把核桃放进这个机子里,盖上盖子,按下启动键。等一会儿,香喷喷的核桃肉就会出现在你眼前。是不是很方便呢? Many people like to eat walnuts, walnuts delicious and nutritious, but the peel is very troublesome. Some people use the clip, someone simply mouth bite, are not convenient. So I want to invent an automatic sheller, as long as you put the walnut into the machine, cover, press the start button. Wait a minute, fragrant walnut meat will appear in front of you. Is it very convenient?
