Pyqt5:self.buttonBox怎么识别clicked？

如题，识别用户按下self.buttonBox
Stackoverflow看过了，CSDN也大概看了看，没几个是pyqt的，so上面的东西搞了半天也没搞懂
试了各种clicked，accepted,rejected啥的，都没好，qt文档说的也云里雾里
不要给我放代码实例，要么把方法说一下，要么直接告诉我怎么办，代码示例我快看吐了

from PyQt5 import QtCore, QtGui, QtWidgets


class Ui_Dialog(object):
    def setupUi(self, Dialog, accepted=None):
        Dialog.setObjectName("Dialog")
        Dialog.setWindowModality(QtCore.Qt.WindowModal)
        Dialog.setEnabled(True)
        Dialog.resize(579, 296)
        Dialog.setCursor(QtGui.QCursor(QtCore.Qt.ArrowCursor))
        Dialog.setFocusPolicy(QtCore.Qt.NoFocus)
        Dialog.setContextMenuPolicy(QtCore.Qt.DefaultContextMenu)
        self.buttonBox = QtWidgets.QDialogButtonBox(Dialog)
        self.buttonBox.setGeometry(QtCore.QRect(40, 240, 341, 32))
        self.buttonBox.setOrientation(QtCore.Qt.Horizontal)
        self.buttonBox.setStandardButtons(QtWidgets.QDialogButtonBox.Cancel | QtWidgets.QDialogButtonBox.Ok)
        self.buttonBox.setObjectName("buttonBox")
        self.checkBox = QtWidgets.QCheckBox(Dialog)
        self.checkBox.setEnabled(True)
        self.checkBox.setGeometry(QtCore.QRect(10, 60, 391, 21))
        self.checkBox.setChecked(False)
        self.checkBox.setAutoRepeat(True)
        self.checkBox.setObjectName("checkBox")
        self.spinBox = QtWidgets.QSpinBox(Dialog)
        self.spinBox.setGeometry(QtCore.QRect(120, 120, 46, 22))
        self.spinBox.setMaximum(60)
        self.spinBox.setObjectName("spinBox")
        self.textBrowser = QtWidgets.QTextBrowser(Dialog)
        self.textBrowser.setGeometry(QtCore.QRect(0, 90, 241, 31))
        self.textBrowser.setObjectName("textBrowser")
        self.textBrowser_2 = QtWidgets.QTextBrowser(Dialog)
        self.textBrowser_2.setGeometry(QtCore.QRect(250, 90, 321, 131))
        self.textBrowser_2.setObjectName("textBrowser_2")
        self.checkBox_2 = QtWidgets.QCheckBox(Dialog)
        self.checkBox_2.setGeometry(QtCore.QRect(400, 60, 151, 19))
        self.checkBox_2.setObjectName("checkBox_2")
        self.textBrowser_3 = QtWidgets.QTextBrowser(Dialog)
        self.textBrowser_3.setGeometry(QtCore.QRect(10, 20, 141, 31))
        self.textBrowser_3.setObjectName("textBrowser_3")
        self.spinBox_2 = QtWidgets.QSpinBox(Dialog)
        self.spinBox_2.setGeometry(QtCore.QRect(0, 120, 46, 22))
        self.spinBox_2.setObjectName("spinBox_2")
        self.spinBox_3 = QtWidgets.QSpinBox(Dialog)
        self.spinBox_3.setGeometry(QtCore.QRect(60, 120, 46, 22))
        self.spinBox_3.setObjectName("spinBox_3")
        self.retranslateUi(Dialog)
        self.buttonBox.accepted.connect(Dialog.accept)  # type: ignore
        self.buttonBox.rejected.connect(Dialog.reject)  # type: ignore
        if QDialog.accepted(self.buttonBox.Ok):
            print('1')

Traceback (most recent call last):

    second_ui.setupUi(mainWindowOriginal)
  File "C:\Users\User\PycharmProjects\Python1\USBfording.py", line 82, in setupUi
    if QDialog.accepted(self.buttonBox.Ok):
