Described elevating adjusting device is characterized in that: described fixed bar is a round bar, and described adjustment ring is an annulus, and described bundle groove is the circular beam groove.

Described elevating adjusting device, it is characterized in that: form the grooving that communicates with described bundle groove together in described joint seat, this joint seat forms a neck piece respectively in the both sides of adjacency grooving, described forcing piece is the fixed handle that an outer end forms screw thread, and this forcing piece passes this neck piece and screw lock is gone into urgent this two neck piece of another neck piece and tightened this bundle groove.

Described elevating adjusting device is characterized in that: form one in described adjustment ring and run through the screw of this adjustment ring in abutting connection with the fracture two ends, described fastener is a bolt, and this bolt screw lock is gone into this screw.

Described elevating adjusting device, it is characterized in that: form the grooving that communicates with described bundle groove together in described joint seat, this joint seat forms a neck piece respectively in the both sides of adjacency grooving, described forcing piece is the fixed handle that an outer end forms screw thread, and this forcing piece passes a neck piece and screw lock is gone into urgent this two neck piece of another neck piece and tightened this bundle groove.

The utility model is established motion arm with this binding seated connection, and adjusts ring with this and adjust this joint seat in this fixed bar height up and down.

By this, make the adjustable self-contained height of establishing the motion arm integral body on it of the utility model.
