<p>A mechanism for cutting driving of a lopper comprises an operating lever (1), a movable sleeve (3), a drive shaft (6) and a drive connection shaft (9). The drive shaft (6) is mounted on an inner side of the operating lever (1). A retaining ring (10) is mounted at a lower end of the drive shaft (6). The drive connection shaft (9) on a lower side of the drive shaft (6) is connected to an inner wall at a lower end of the operating lever (1). A gear (8) is fixedly connected to an upper end of the drive connection shaft (9). A bolt (2) is vertically mounted in a protruding portion on a right side of the operating lever (1). The movable sleeve (3) is mounted outside the operating lever (1) and wraps the operating lever (1). A fork block (4) is horizontally mounted at a lower end on a right side of the movable sleeve (3). The fork block (4) runs through a slot-shaped through hole (13), and is urged against a lower edge of a step on a side of the retaining ring (10). The structure is simple in structure, makes operation convenient, and can rapidly cut the drive line of a lopper to immediately stop a cuter working.</p> |
