Description

Clamping device of telescopic rod

Technical Field

The invention relates to the field of telescopic rods, in particular to a clamping device of a telescopic rod.

Background

The pruning and fruit picking of fruit trees are indispensable important links in the growth management period of the fruit trees. The fruit production quantity of China is at the first place in the world, the fruit tree planting distribution land spans the south and north of the great river, and a large amount of orchard pruning and picking operation quantity is generated. Although picking machines in China are rapidly developed, picking machines such as pickers and power pruning picking tools are applied; however, most of the existing machines have single functions and cannot solve the practical problems in orchard production. The tree pruning and fruit picking operation is carried out by utilizing the high branch scissors, the handle is operated by the grip force of human hands, the cutter is driven to open and close, and branches are cut off or fruits are picked; however, the traditional high branch shears are not adjustable in length due to the fact that the branches are different in height, and operation is inconvenient. Fruit tree pruning can be carried out in the orchard all the year round, fruit tree pruning brings great benefits to the growth of fruit trees, redundant branch coverage is reduced, an effective leaf curtain layer is improved, the effective leaf coefficient is increased, and photosynthesis is improved. The leaves are the places for the photosynthesis of the fruit trees, and the photosynthesis can accumulate sufficient organic nutrition for the fruit trees and promote the high yield of the fruit trees. The apical dominance of the growth of the fruit tree branches is controlled by pruning the branches, and flower bud differentiation is promoted. After pruning, the growth of the top ends of the branches stops in summer, nutrients are not consumed on the growth of the top ends, leaf clusters are formed at the top ends of the branches, the leaves are large in volume and are mature leaves, the photosynthetic efficiency is high, the nutrient accumulation of the branches can be increased, the concentration of the cytoplasm of terminal buds is increased, the flower bud differentiation can be completed, and the flowers can bloom in the spring of 2 years. The fruit tree can be pruned to overcome the phenomena of fruiting at the periphery of the tree body and the yield of the fruit tree in big and small years. The trees grow naturally, the inner branches are too dense, and fruiting parts expand outwards. The current-year yield of the fruit tree is excessively improved, the nutrition of the tree body is deficient, the 2 nd year blossoming and fruiting are less, the yield is reduced, and the year is big or small.
