Set is outer；Outer locking adjusting set inwall has been formed radially regulation ring, and described regulation ring is located at outer jacking block side and both offset.
The axial direction at the left and right two ends of described outer locking adjusting set is surveyed all stroke limit block, and described stroke limit block exists
Extension tube II and interior positioning put and are respectively provided with one.
Be provided with described outer locking adjusting set one be enclosed within default position set outside reset assembly, one end of reset assembly with outer
One end of locking adjusting set is connected and moves with outer locking adjusting set, and the other end of reset assembly is fixed on extension tube I or default
Position puts.
Described elastic component is two groups and becomes to be symmetrical arranged.
A wherein axial end and the interior positioning sleeve of described elastic component is fixedly linked, and elastic component is integrally become with interior positioning sleeve
Type, hollow out design between the two sides of interior positioning sleeve and top and interior positioning sleeve.
Described reset assembly is helical spring.
The invention has the beneficial effects as follows：Axially-movable reality of the expansion link of the present invention with locking device by outer locking adjusting set
The radial motion of existing elastic component, completes connecting or separating for interior jacking block and locating slot, as interior jacking block and locating slot belong to embedded
Formula coordinate, axial direction can bear very big power, be not in slip phenomenon, at the same do not exist yet because part abrasion and
The situation of impact coupling mechanism force, therefore the invention enables the connection between adjacent pole is relatively reliable.
