First of all, if you really want to dismantle it yourself, you must be careful. If the socket is broken, it will be scrapped. Stay away from the children when disassembling it. The piano and the base each have a left and a right socket, and each has four small sockets. If you break one by one, you may break one and close one, so I have a fixing method, first fix the broken one, and then remove the next one. You can also think of something else. Gently separate the plastic pieces on the left and right sides of the small socket with a thin flat-headed screwdriver, and insert a pin, preferably a round-headed pin, to prevent it from closing. Make four small sockets in turn, and then gently push the plastic piece in the middle of each socket. As long as the button is pushed in, the bead needle can be pulled out, and then the piano and the base can be easily separated.
