Abstract
A paint roller with an end-surface blocking structure is provided with a mounting stem coupled to a handle, a roller sleeved on the mounting stem, a connecting sleeve sleeved on the mounting stem, and an end-surface blocking piece pivoted to the connecting sleeve. The pivot connection of the connecting sleeve with the second pivot allows the connecting sleeve to pivot around the first direction and allows the end-surface blocking piece which is pivoted to the connecting sleeve to pivot around the second direction, so that the end-surface blocking piece is capable of rotating in two different directions, which improves flexibility when operating the paint roller.
