I knew that there was only an adapter part, and I could repair the tool cheaply.
I would like to say that it would have been better if we had prepared several types of adapters, such as short objects and long objects of the full length of the adapter.
Also, we request parts only with springs.
I used a lost adapter and had a puller that the end of the screw had collapsed but I knew that the parts will be supplied, so I bought it. Although it could not be mounted as it was, it machined the tip of the screw with a lathe and processed it for the ball and the stop ring to fit well. Thanks to that, I cheaply fixed it.
