假期的一天,我去安吉参观了一家锁厂。走进锁的装配室,只见弹子、销子等零件放满了整个车间。在我的央求下,一位阿姨做了装锁示范。只见她熟练地把钥匙塞进锁心里,并装进几颗弹子,随后用锉刀一锉,将弹子连锁心一道放入锁头,再将弹子推入锁头的小孔里,然后用铜皮封住,一把锁就装好了。 One day during the holidays, I went to Angie to visit a lock factory. Into the lock assembly room, saw the marbles, pins and other parts full of the entire workshop. In my request, an aunt made a lock model. I saw her skillfully put the key into the lock heart, and loaded into a few marbles, and then file with a file, the marbles together into the lock chain, and then push the pin into the hole in the lock, and then use copper Leather seal, a lock on the installed.
