Description

A kind of efficient scissors for picking fruit or flowers

Technical field

The utility model relates to a kind of efficient scissors for picking fruit or flowers, belongs to agriculture production special tool technical field.

Background technology

Fully supplying to ensure the nutrient of fruit and improve the quality of fruit, the growth of most fruit all needs to carry out flower and fruit thinning work early stage. Flower and fruit thinning process is divided into two stages and carries out, first stage, for carrying the pawl stage, is about to not need the colored pawl retained, the fruit whole pawl of pawl to wipe out, and subordinate phase is the fixed fruit stage, after being about to carry pawl unnecessary flower in remaining flower pawl, fruit pawl, fruit wipe out, retain selected healthy and strong flower, really. Current people's flower and fruit thinning common scissors of many employings carries out; owing to common scissors is single clip; and not there is the function of protectiveness reservation flower, fruit; not only put forward pawl speed slower; and for avoiding injuring for retaining flower, really during fixed fruit; need meticulously to for retaining flower, fruit flower around, fruit wipe out, working efficiency is also extremely low. In addition, closed, the stretching degree of common scissors clip and the urgent conjunction of shear-blade all control by staff, very require great effort, also affect the raising of flower and fruit thinning working efficiency. Therefore, research and develop new and effective flower and fruit thinning instrument and seem necessary.
