Brushes are tools with bristles, wires or other filaments, used for cleaning, grooming, makeup, painting, surface treatment and many other purposes. It is one of the most basic and widely used tools known to human beings. On average, each family may contain dozens of varieties. It is usually composed of a handle or a block. According to the way of holding the brush in use, the wire can be fixed on the handle or block in a parallel or vertical way. Choose block and bristle or filament materials to withstand the risks of their application, such as corrosive chemicals, heat or wear.

A common way to fix the brush and brush wire in the brush is stapling or anchoring brush, in which the stapling screw is used in the middle to push the fine wire into the hole with a special screwdriver and fix it here through the reaction force. The wall of a hole and the part of a staple nailed to the bottom of the hole. Staples can be replaced by an anchor, which is a rectangular outline fixed to the wall of the hole like most toothbrushes. Another way to attach bristles to a surface can be found in a fused brush, where plastic fibers are welded to another plastic surface instead of being inserted into a hole, giving the option of using bristles of different diameters in the same brush.
