Abstract
A dental prophy angle includes a housing, a driving assembly, a first limiting member, a second limiting member, and a prophy cup, where the driving assembly includes a first driving shaft and a second driving shaft; the second driving shaft comprises one end connected to the first driving shaft by a gearing connection, and the other end provided with the prophy cup; and the first limiting member is sleeved on the first driving shaft and locates between the first driving shaft and an inner wall of the housing, and the second limiting member is sleeved on the second driving shaft and locates between the second driving shaft and the inner wall of the housing, to play a position limiting role and prevent the first driving shaft from falling out. The first limiting member is in snap connection with the housing for fixation, which makes the installation simple.
