The utility model is set to further: described stationary installation comprises Ω pencil of forms circle, adjusting bolt and quick detach spanner, described Ω pencil of forms snare is installed on support bar, this support bar relative Ω pencil of forms circle opening part is provided with a breach, described adjusting bolt is through the opening part of Ω pencil of forms circle, and described quick detach spanner matches with Ω pencil of forms circle.
By adopting technique scheme, utilize quick detach spanner change in radius to change the opening distance of Ω pencil of forms circle, its opening is apart from becoming large, sit pipe and be provided with a breach with Ω pencil of forms circle corresponding section, the breach being enclosed within the support bar in Ω pencil of forms circle becomes ambassador's support bar and stretching bar gap enlargement, pipe is in loosening state with seat pipe, and reaching the stretching bar being set in support bar inside can stretch, thus changes the length of the entirety of support bar.
The utility model is set to further: described support bar is uniformly distributed along centering rod in axial.
By adopting technique scheme, centering rod can be made more stable fixing of hard ground.
The utility model is set to further: described stretching masthead end is provided with rubber ball body, and described rubber ball body and stretching bar are for removably connecting.
By adopting technique scheme, being provided with rubber ball body can be better fixing on the hard ground of surface irregularity, because rubber ball body and stretching bar are that screw thread removably connects, so it can be screwed off in time not needing to use rubber ball body.
The utility model is set to further: centering rod is provided with a set collar, and described rubber sphere physical efficiency and centering rod removably connect.
By adopting technique scheme, in time not using support bar, support bar and rubber ball body are fixed on centering rod, when using the situation of support bar, just support bar can be unloaded the erection carried out on the ground.
The utility model is set to further: be provided with gravity balancing point on described centering rod.
By adopting technique scheme, the rectification can being undertaken RTK sounding rod equilibrium position by the gravity balancing point on centering rod, realizes the balance of RTK sounding rod by the length adjusting support bar.
