Description

High-yield pruning device for green Chinese prickly ash

Technical Field

The utility model relates to the technical field of green peppers, in particular to a high-yield pruning device for green peppers.

Background

The pruning method of the pepper tree is commonly used for short-cut, branch thinning, retraction and the like, and corresponding pruning methods are adopted according to different growth stages. The principle that the young trees are well shaped and have repeated results is mastered; the fruiting tree is required to gradually remove redundant big branches, mainly removes branches in the crown, and removes weak branches and keeps strong branches, so that branches in the crown are robust and balanced, and are ventilated and transparent; the old trees mainly adopt thinning and shearing, draw big branches, remove weak branches, leave big buds and timely renew and rejuvenate fruiting branch groups. The young trees and the full fruit trees are suitable for being trimmed in autumn, and the weak trees and the old trees are suitable for being trimmed in spring. During pruning, dry and dead branches, dense branches and insect-disease branches are cut off, the insect-disease branches are burnt intensively, workers who use the pruning scissors can cut off the inconsistent branches, the branches can be conveniently and rapidly trimmed by a special trimming tool, and the working efficiency of users is greatly improved by the trimming tool;

for example, the pruning shears with the safety locking mechanism disclosed in patent No. CN202121133589.4 have a safety locking mechanism on the main body. The pruning shears with the safety locking mechanism have the advantages of simple structure and low production cost; the movable handle and the auxiliary blade are in transmission through the gear, and the transmission force is large, so that the aim of easily shearing is fulfilled; the safety locking mechanism is arranged, when the cutter is not used, the two blades can be locked in a closed state, the blades are prevented from accidentally injuring people, and the use is safe.

Present green prickly ash high yield pruning device is when using, and the gum cover on the scissors grab handle can take place not hard up at the in-process of long-time use, and the gum cover will take place to remove on the grab handle like this to make user's hand can't effectually hold on the gum cover outer wall, consequently need improve according to the not enough of current product, in order to satisfy people's user demand.

SUMMERY OF THE UTILITY MODEL
