Abstract
A dual handle speed adjustment device includes left and right handles, a link and a slider. The left and right handles each have an actuating end, an operating end and a handle hinge as a pivot axis. The slider has a first connection end connected to the actuating ends of the left and right handles, a second connection end connected to a speed control device, and a part between the first and second connection ends hinged to one end of the link, which has the other end thereof provided with a link rotation axis. The left and right handles independently drive the slider to move when they are turned. The invention can realize the separate operation of two speed adjusting handles.
