The chain lock is not locked according to the canon, it should be the back of the latch in the direction of the chain stroke, and it is locked the other way around. Otherwise, the lock is installed correctly, the latch is located on the inside of the chain.

I'm tired of pulling up the chain often, plus the adjusting screws with lock nuts are inconveniently located, you screw them up, the keys 13mm and 14mm barely fit. To loosen/unscrew the rear axle, 17mm and 21mm heads are needed. To turn the rear axle nut for the first time, I used a 350 mm lever.
