python - When using scrapy, why can the loop only get the first page?

Question

class OnlineSpider(scrapy.Spider):
name = "online"
allowed_domains = ["www.onlinedown.net"]
start_urls = ['http://www.onlinedown.net/new/android/','http://www.onlinedown.net/new/ios/','http://www.onlinedown.net/new/windows/']#
model = Model('onlinedown')

def start_request(self):
    for url in self.start_urls:
        for x in range(1, 100):
            detail_url = url + str(x) + '.html'
            print detail_url
            yield scrapy.Request(detail_url, callback = self.parse)
            

There are 35 items per page, and the result is 105 items. Why is this.
