pyqt5中QFileDialog的保存链接问题

xecel已编辑好，用QFileDialog控件的保存功能怎么建立信号与保存按键的联动

from PyQt5.Qt import *
import openpyxl

class Window(QWidget):
    def __init__(self):
        super().__init__()
        self.setWindowTitle('保存问题')
        self.resize(500,500)
        self.setup_ui()

    def setup_ui(self):
        wb = openpyxl.load_workbook('The data.xlsx')
        wb_sheet = wb.active
        wb_sheet['E2'] = 22
        save1 = QFileDialog(self, '选择保存位置', '../', 'All(*.*);;Excel(.xlsx)')
        save1.setAcceptMode(QFileDialog.AcceptSave)
        save1.setDefaultSuffix('xlsx')
        save1.directoryEntered.connect()
        save1.open()
        wb.save(把修改好的wb保存到选择的路径下面（怎么建立保存按钮
        和save1.directoryEntered.connect()直接的联动关系？）)
if __name__ == '__main__':
    import sys
    app = QApplication(sys.argv)
    window = Window()

    window.show()

    sys.exit(app.exec_())
