リツイートのみを取り込みたい

Question

1,指定したユーザーのリツイートしたもののみの画像を取り込みたいです
2,line29の検索部分を変えるだけだと思うがうまくいかない
3,python3.10

import os
import tweepy
from config import CONFIG
from time import sleep
import urllib.error
import urllib.request

CONSUMER_KEY = CONFIG["CONSUMER_KEY"]
CONSUMER_SECRET = CONFIG["CONSUMER_SECRET"]
ACCESS_TOKEN = CONFIG["ACCESS_TOKEN"]
ACCESS_SECRET = CONFIG["ACCESS_SECRET"]

auth = tweepy.OAuthHandler(CONSUMER_KEY, CONSUMER_SECRET)
auth.set_access_token(ACCESS_TOKEN, ACCESS_SECRET)
api = tweepy.API(auth)


def download_file(url, dst_path):
   try:
       with urllib.request.urlopen(url) as web_file:
           data = web_file.read()
           with open(dst_path, mode='wb') as local_file:
               local_file.write(data)
   except urllib.error.URLError as e:
       print(e)
       
key_account = input('Enter account name:')
count_no = int(input('Set search count:'))
search_results = tweepy.Cursor(api.user_timeline, screen_name=key_account).items(count_no)#ここをリツイートのみ取り込めるようにした

if not os.path.exists(key_account):
   os.mkdir(key_account)

i = 0

for result in search_results:
   try:
       img_url = result.extended_entities['media'][0]['media_url']
       dst_path = '{0}/{1}.png'.format(key_account,i)
       download_file(img_url,dst_path)
       i += 1
       sleep(1)
   except:
       pass
