The rationale and construction of the copper lock
At the bottom of the lock core there are three shrapnel pieces, the right side of a beam under the lock core, the left side stretches out, and when the lock is up, the lock core is inserted along the sink from the left side of the lock, and the shrapnel is pressed and successfully inserted into the lock core. Then the shrapnel came out naturally, because the chute size was just enough to be inserted when the shrapnel was pressed. When the shrapnel was opened, it was just holding the lock on the left, so the copper lock was locked
And again, the principle of unlocking is that it's a simple one. When the lock is unlocked, the key opening the same hole at the top is inserted from the right side, and the key continues to be pushed forward, the key moves forward along the slot, and the key hole presses as it moves forward, so that the lock core is free of resistance and is pushed out from the left. The depth of the hole in the key ensures that once the lock core is pushed out, it does not fall into the shell itself。
