如何在PyQt5图形用户界面中运行两个无限循环？

from PyQt5.QtCore import QThread, pyqtSignal
from PyQt5.QtWidgets import QApplication, QMainWindow, QPushButton

# 创建线程类
class WorkerThread(QThread):
    # 定义信号，用于传递线程的结果或状态
    thread_signal = pyqtSignal(str)
    
    def run(self):
        while True:
            # 执行无限循环的操作
            # ...

            # 发送信号
            self.thread_signal.emit("Thread 1: Operation completed")

# 主窗口类
class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()

        # 创建按钮
        self.button1 = QPushButton("Start Thread 1", self)
        self.button1.clicked.connect(self.start_thread1)
        
        self.button2 = QPushButton("Start Thread 2", self)
        self.button2.clicked.connect(self.start_thread2)

        self.setCentralWidget(self.button1)
        self.setWindowTitle("PyQt5 Example")
        self.show()
    
    # 启动线程1
    def start_thread1(self):
        self.thread1 = WorkerThread()
        self.thread1.thread_signal.connect(self.update_status)
        self.thread1.start()
    
    # 启动线程2
    def start_thread2(self):
        self.thread2 = WorkerThread()
        self.thread2.thread_signal.connect(self.update_status)
        self.thread2.start()
    
    # 更新状态
    def update_status(self, status):
        print(status)
        # 在图形用户界面中进行状态的更新
        # ...

# 创建应用程序对象
app = QApplication([])
window = MainWindow()
app.exec()
