Place the handle upside down on the table. 2. Insert the needle vertically into the slot. 3. When you insert the needle for the first time, you will find that there is foam in the needle groove. Its function is to fix the needle in the needle groove and prevent the needle from falling off, so you need to use a certain amount of force to puncture the foam.
