Special ladder for garden tree branch trimming
The invention provides a special ladder for garden tree branch trimming. A base with a hole is fixed on a base plate, a movable pin is connected with the base and a movable base, the angle between the base plate and the movable base is adjusted through a gravity cone and locked with a locking screw, the external conical surface of the lower end of each supporting column body is matched with the movable base or the internal surface of an internal conical hole of a supporting column body below to be fixed, and each internal conical surface and the corresponding external conical surface which are well attached are automatically locked through matching of an annular locking groove on the corresponding external conical surface and a corresponding locking pin after the corresponding internal conical hole and the corresponding external conical surface are matched and well fixed. Folding pedals capable of being folded in one end, provided with a connector, of each supporting column body are fixed on the surface of the corresponding supporting column body, and anti-sliding glue is applied to the bottom of the base plate. The special ladder for garden tree branch trimming is simple in structure and very convenient to manufacture, assemble, use and carry, tools are not required in assembly and disassembly processes when the ladder is used, the upright climbing and standing problem of gardeners during tree branch trimming is solved, the ladder assembly speed is high when the gardeners climb, and the ladder is safe, reliable and convenient to climb and is convenient to disassemble, pack and transport after used.
