Further, the pedestal includes fixed plate, the fixed column for being placed in fixed plate center, second mounting hole
Aperture be placed in fixed plate center, which extends in fixed column, the stiffening plate and fixed plate phase
Even.
When the utility model is used, it is respectively that the first fixing seat and the second fixing seat is prefabricated in section of jurisdiction, it carries out cyclic annular
When structures to form, the helicitic texture for connecting plunger is threadedly connected in the second mounting hole of the second fixing seat first, then will be even
The other end for connecing plunger is installed in the first mounting hole of the first fixing seat, the limit of the limiting slot and broached-tooth design of broached-tooth design
Pawl, which cooperates, (when connecting column enters in the first mounting hole, to be limited pawl along the inclined direction of limiting slot, makes to install
More smoothly；And when extracting connection plunger out of first mounting hole, limiting slot can be hindered to limit pawl, prevent connection plunger
Skid off outside the first mounting hole), make connection plunger that the first fixing seat, the second fixing seat to be firmly connected to form one, thus by phase
Adjacent two sections of jurisdiction splicing is integral.The first fixing seat that rotary table seat and attachment base are formed, pedestal, stiffening plate, reinforcing rib are constituted
The second fixing seat, compared with arch screw bolt before, so that external force relative distribution, fixed device is unlikely to deform.
The utility model is simple and reasonable, manufactures and is easy, all parts are unlikely to deform in section of jurisdiction, improve pipe
Connectivity robustness between piece, it is easy for installation, it is time saving and energy saving.
