| 摘要 | The scaler comprises an elongated and axially hollow handpiece (1), a rotatable holder (2) accommodated internally of the handpiece (1) and housing drive means (4) for a detachable scaling implement (6), and a light source (7) associated rigidly with the handpiece (1), and incorporates a locking mechanism in the form of a pin (8) and a number of corresponding sockets (9) distributed circumferentially around the longitudinal axis (3) of the holder (2); the holder is spring-loaded and slidable axially between a stable position in which the locking mechanism is engaged, and a non-stable position in which the pin and sockets (8, 9) are disengaged and the holder (2) and the handpiece (1) free to rotate one in relation to the other between two limit positions established by circumferential slots. | ||||||
