The water spray device can reduce the high temperature generated during the drilling process and prevent waste chips from flying during the drilling process, thereby making it safer and more reliable to use.

[0004] In the above technical solution, the inventors found that there are at least the following problems: the water sprayed by the water spray device can reduce the high temperature generated during the drilling process and the flying of waste chips during the drilling process; however, after spraying, the water spray device cannot collect and recycle the water discharged from the drain pipe for reuse, resulting in a waste of water resources. Therefore, how to design a sole drilling device for leather shoe processing has become a problem that we currently need to solve. Utility Model Content
