PURPOSE: A method for mounting a net on a metal cylinder for a horse tail sieve is provided to facilitate drying, cleaning, and keeping. CONSTITUTION: A horse tail sieve(2) is formed between two metal cylinders(1). A protrusion is formed on the surface of the cylinder. The protrusion is naturally received on the part of the horsehair sieve. The horsehair sieve on the bottom is smoothly fixed by fixing the horsehair sieve to the cylinders to perform a filtering operation. |
