It is very convenient to add a connector for other models that cannot be hung on the wall, so that it can be hung on the wall.

For example, the cover picture, this broom holder needs to use nails to hang on the wall, but after the addition of this female buckle can be flexibly disassembled.

The sub-buckle on the wall is a square buckle bought on Taobao.

If you don't want to buy it, I also made a model of the buckle, and upload it later.

可以很方便的为其他无法挂在墙上的模型添加一个连接件，使其可以挂在墙上。

例如封面图片，此扫把支架需要使用钉子才能挂在墙上，但是添加这个母扣之后就可以灵活拆换了。

墙上的子扣是在淘宝上买的方扣。如果不想购买的话我也做了子扣的模型，稍后上传。
