Pyqt如何利用线程去调用ui界面代码中的QlineEdit模块的输入

Question

我使用QtDesigner设计了ui界面并且用PyUI生成ui界面的.py文件。之后我另外开了一个py脚本调用主界面，为了防止运行循环导致界面卡死，我写了一个子线程，但是怎么在子线程去调用ui界面代码中的QlineEdit模块？请问有没有大佬能帮小弟解决已经搞了快两周了还没解决！！

from PCANBasic import *
import time
import sys
from PyQt5.QtWidgets import QApplication, QDialog
from PyQt5.QtCore import *
from testcan import Ui_can_test

class can_thread2(QThread,Ui_can_test):
    def __init__(self):
        super(can_thread2, self).__init__()

    def run(self):
        #想调用生成testcan界面下的QlineEdit模块的输入内容
        msg.ID = int(self.ID_Edit.text()) 
        msg.LEN = int(self.Len.text())
        msg.DATA[0] = int(self.data0.text())
        msg.DATA[1] = int(self.data1.text())
        msg.DATA[2] = int(self.data2.text())
        msg.DATA[3] = int(self.data3.text())
        msg.DATA[4] = int(self.data4.text())
        msg.DATA[5] = int(self.data5.text())
        msg.DATA[6] = int(self.data6.text())
        msg.DATA[7] = int(self.data7.text())

        objPCAN.Write(PCAN_USBBUS1, msg)


class can_test_win(QDialog, Ui_can_test):
    def __init__(self):
        super(can_test_win, self).__init__()
        self.setupUi(self)

        self.thread2 = can_thread2()
        self.send_btn2.clicked.connect(lambda :self.thread2.start())

if __name__ == "__main__":
    app = QApplication(sys.argv)
    MainWin = can_test_win()

    objPCAN = PCANBasic()
    objPCAN.Initialize(PCAN_USBBUS1, PCAN_BAUD_500K)
    msg = TPCANMsg()
    msg.MSGTYPE = PCAN_MESSAGE_STANDARD
    MainWin.show()

    sys.exit(app.exec())
