The utility model discloses can further set up to: the spliced pole including the base, base and installation department between can dismantle and be connected.

Through further setting, through the dismantlement between base and the installation department being connected, when being convenient for deal with different specification tripod, to the change of spliced pole.

The utility model discloses can further set up to: the support on be provided with guide rail and locating part, the frame head can slide along the guide rail, the locating part setting on the motion route of frame head, and the locating part can form the butt spacing with the bulb of tripod.

Through further setting up, set up the locating part that is located on the motion route of frame head on the support to through the butt cooperation between the bulb of locating part and tripod, increase the stability of location, during the better grinding operation of avoiding, because the vibration leads to the condition that the tripod produced the displacement.

The utility model discloses can further set up to: the support on be provided with the supporting seat, the supporting seat on be provided with the guide way, the locating part can slide from top to bottom along the guide way.

Through further setting up, can adjust the height of locating part according to the tripod of different specifications.
