Abstract
The utility model relates to a tone sandhi clamp which comprises an upper clamp, a lower clamp, a rolling element, an elastic component and a shifting ring. The upper clamp and the lower clamp are rotatably arranged and are buckled to form a wedge groove. The rolling element is rollingly arranged in the wedge groove. The shifting ring extends into the wedge groove and clings to one side of the rolling element, and the other side of the rolling element clings to the elastic component. Pressed by external force, the upper clamp and the lower clamp rotate relative to each other; the elastic component drives the rolling element to roll to a narrower section of the wedge groove along a wider section of the wedge groove; and friction is generated between the rolling element and the upper clamp and between the rolling element and the lower clamp for self-locking so as to realize chucking and latching. The shifting ring is pushed by external force so as to drive the rolling element to roll to the narrower section of the wedge groove along the wider section of the wedge groove so as to realize unlocking and separation. By the unilateral bearing theory, stepless regulation can be realized during the chucking and latching process, and the regulation process is precise; during the unlocking and separation process, the shifting ring is directly pushed; the operation is convenient and fast, and force is little.
