push plate 163 is pushed by the fourth hydraulic cylinder 161 to drive the back plate 156 to slide, the back plate 156 drives the fixture block assembly 157 to slide towards the direction close to the sliding seat 115, the fixture posts 120 extend into the circular hole 171, because the lengths of the fixture posts 120 are different, the pushing distance of the push plate 163 determines the number of the fixture posts 120 extending into the circular hole 171, when the number of the fixture posts 120 extending into the circular hole 171 meets the number of the sliding seat 115 required for use, the double-head motor 162 is started, the double-head motor 162 drives the first fixture block 165 to slide, the first fixture block 165 overcomes the resistance of the blocking piece 168 to drive the sliding seat 115 corresponding to the first fixture block to slide, and because of the existence of the long groove 172 and the limiting post 173, the first fixture block 165 and the second fixture block 166 are firstly driven to slide away from a distance, and the second fixture block 166 and the third fixture block 167 are driven to slide together, so as to drive the sliding seat 115 to slide, the sliding bases 115 are in contact with the spline shaft 124, the spline shaft 124 drives the sliding bases 115 to work, the distance between the sliding bases 115 is uniform, meanwhile, the sliding bases can freely move to a required position, and the positions of the sliding bases 115 are uniformly distributed, so that the stability of hoisting the tower is guaranteed.

The present invention is not limited to the above-described embodiments, and those skilled in the art will be able to make various modifications without creative efforts from the above-described conception and fall within the scope of the present invention.
