It moves, realizes that position-limiting drum can slide on the rotating shaft, since second sliding slot partially protrudes into limit circular groove, so as to meet position-limiting drum
It slides into limit circular groove.
Be further arranged to: the position-limiting drum has been wholely set diameter greater than the limit far from the end of the limited block
The annular hand-held part of circular groove.
By using above-mentioned technical proposal, hand-held part turns people to rotation axis in the height for needing to change mounting table
It moves more convenient.
It is further arranged to: radially spaced in the peripheral outer wall of the hand-held part to be provided with several raised lines.
By using above-mentioned technical proposal, it is more convenient when hand-held part further to make to need to rotate, and not will cause skidding.
Be further arranged to: the second sliding slot is in one end outside the supporting table and described the far from the rotation axis
Two convex blocks are connected with spring between one end of the supporting table.
It by using above-mentioned technical proposal, skid off position-limiting drum will not arbitrarily in its natural state outside limit circular groove, thus
Cause mounting table to drive rotation axis to rotate under the effect of gravity, improves the stability of mounting table.
Be further arranged to: the bottom end of the support leg is provided with stabilizer blade, and the stabilizer blade includes the top for being inserted into ground
Point and the baffle for being connected horizontally on top top.
By using above-mentioned technical proposal, when using bracket, positioning action is played to supporting leg in top insertion bottom surface,
Supporting leg continues to sink when baffle can prevent soil soft simultaneously, is conducive to total station bracket and keeps balance.
In conclusion the advantageous effects of the utility model are as follows:
(1) change is adjusted in the height that the mounting table of placing total station can be achieved;
(2) regulative mode is simple, and mounting table can be stably held in a certain height.
