The stability that interior bar and positioning outer bar are fixed.
Further, positioning outer bar is hollow tube-shape.
The convenient positioning outer bar of hollow tube-shape is enclosed within positioning interior bar, it is ensured that positioning interior bar and positioning outer bar relative motion
Space.
Further, the inwall that positioning outer bar is located in first through hole is provided with the second block.
When positioning outer bar is needed, the shaft shoulder in positioning interior bar props up the second block, it is ensured that can position outer bar at promotion.
Further, the first block is installed with stage clip.
When positioning interior bar is needed, the shaft shoulder in positioning outer bar props up stage clip not to be continued to stretch out first through hole, is made in positioning
Bar stretches out first through hole, and when positioning outer bar is needed, continues to press on positioning interior bar, because the shaft shoulder in positioning interior bar can be propped up
Second block, positioning interior bar will not continue to stretch out, the shaft shoulder in positioning outer bar can compression press spring, positioning outer bar is continued to stretch out the
One through hole, during compression press spring, positioning interior bar is connected with bush whorl, and positioning interior bar will not be retreated due to the elastic force of stage clip, fixed
The regulation of position interior bar and positioning outer bar is more accurate and stable.
Further, the end that positioning interior bar and positioning outer bar are located in first through hole is smooth sphere.
The end of smooth sphere can not leave and draw when interior bar and positioning outer bar is positioned with Gear Contact on gear
Trace.
