Description

Technical Field

[0001] The present invention relates to the technical field of drill guns, and particularly relates to a quick connection device for the front end of a drill gun. Background Art

[0002] In operations such as drilling and punching, the connection between the drill gun and the drill bit is a key link. Traditional connection methods mostly use direct threaded connection or snap connection. These methods often take a relatively long time for connection and disconnection, and are inconvenient to operate. Especially when the drill bit needs to be frequently replaced or when working in different working scenarios, the traditional connection methods seriously affect work efficiency.

[0003] In addition, the handling of debris generated during the drilling process is also a problem. The debris is not only easy to splash and injure people, but may also pollute the working environment. Although there are some debris collection devices on the market, they are often complex in structure, inconvenient to install, and have poor collection effects. Summary of the Invention
