try this:

    $objectManager = \Magento\Framework\App\ObjectManager::getInstance();
    $cart = $objectManager->get('\Magento\Checkout\Model\Cart'); 
    echo $cartId=$cart->getQuote()->getId();

    $itemId = 720;
    $itemQty = 1;

    $quote = $this->quoteRepository->getActive($cartId);
    $cartitems = $cart->getQuote()->getAllItems();

    $quoteItems[] = $cartitems;
