One, What should I do if the lock spring of the suitcase is broken?
The existing lock needs to be replaced.
The replacement method is as follows: The lock consists of six components: three large gears and three small gears, as well as six springs, consisting of three small springs and three large springs. One of the three large springs is particularly soft, and there is also a triangular plastic part. First, install the large gears with the numbered side facing down. Then, place the small gears on top of the large gears, with the notches facing upwards. Next, insert the small springs into the gears, with the two large springs placed in the key. Then, insert the soft spring into the concave groove at the end of the triangular part, with the triangular groove facing upwards and placed in the center of the key, with the triangular front facing the gear. Finally, place the rear cover. Use a flashlight to shine into the three small holes on the rear cover of the lock, turning each gear to the position with the notch facing upwards. This is the current code. Press the key to set the desired number and release the key. Then, install the lock on the suitcase.
