Description

Environmentally friendly dust-free sander

technical field

The utility model relates to an environment-friendly dust-free grinder.

Background technique

In engineering construction, the traditional wall polishing grinder is a kind of plate grinder, by sandwiching sandpaper on the plate, and then the construction personnel manually polish on the wall. This kind of sander has a simple structure and is easy to use, but the utilization rate of the sandpaper is low and a large amount of dust will be generated during the sanding process. These dusts are scattered in the air because they cannot be collected, and the construction workers are very easy to inhale them. Even with a mask, the dust can also It enters into the lungs of the construction workers and causes serious damage to the expiratory organs of the construction workers.

Utility model content
