A vertical ladder specially used for garden pruning
A vertical ladder specially used for garden pruning is disclosed. A stabilizing base of the vertical ladder is fixed by matching between an inner conical hole in the middle and an outer conical surface at the lower end of a vertical cylinder. The outer conical surface of a vertical cylinder is matched with the inner conical surface of an inner conical hole of a corresponding vertical cylinder so as to achieve fixation. After an inner conical hole and a corresponding outer conical surface are matched and fixed, the corresponding inner conical surface and the corresponding outer conical surface are automatically locked by matching between a locking groove in a corresponding locking bar and a corresponding locking pin. Pedals are fixed to the cylindrical surface of each vertical cylinder and are adhered with anti-skip rubber. The bottom of the stabilizing base is adhered with the anti-skip rubber. The vertical ladder is simple in structure, and convenient to manufacture, assemble and use. Assembling and dismounting processes when the vertical ladder is used are free of tools. By adoption of the vertical ladder, the difficult problem of vertical climbing for garden managers is overcome. During vertical climbing, the vertical ladder is rapid in assembling, convenient, safe, reliable and convenient to climb. After the vertical ladder is used, dismounting, packaging, and transportation of the ladder are convenient, thus reducing production and using costs.
