Abstract
A detachable rongeur has a main body, a slider and a movable handle. A front end of the main body has a cutting edge. The movable handle is hinged to both the main body and the slider. The movable handle can drive the slider to move along first sliding grooves. A cheek portion of the main body includes a trigger lock catch structure. The movable handle can be pulled back and forth. An upper portion of the movable handle includes a first feature portion and a second feature portion that are sequentially arranged from bottom to top. The trigger lock catch structure abuts against the first feature portion or the second feature portion.
