Hello First of all, when it is installed, it is squeezed out of shape with high-pressure tools, which is disposable, so when it is disassembled, it can only be removed by pressing the head that rises up with a tool such as hand pliers to make a small business trip.
There is a square pin that connects the handle, and it can be opened by turning it.
