        QTimer.singleShot(0, self.thread_check)  # 延迟执行 self.thread_check函数

    # 向下执行向下滚动字体函数
    def append_text_and_scroll(self,text):
        self.textEdit.append(text)
        self.textEdit.ensureCursorVisible()
    
    # 添加内容函数
    def thread_check():
        # 逻辑操作后执行添加内容
        self.append_text_and_scroll("添加内容")

    # 滚动条自动下降
