如何将信号连接到不同线程中的插槽？

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

class WorkerThread(QThread):
    def run(self):
        # 在这里执行您的任务
        pass

class MainWindow(QMainWindow):
    def __init__(self):
        super().__init__()

        self.button = QPushButton('Start', self)
        self.button.clicked.connect(self.start_thread)

    def start_thread(self):
        self.worker_thread = WorkerThread()
        self.worker_thread.start()

if __name__ == '__main__':
    app = QApplication([])
    main_window = MainWindow()
    main_window.show()
    app.exec_()
