Description

Emasculation cutter

Technical field

This utility model relates to fruit tree hybridization, especially a kind of in pear tree crossover process, during emasculation step, and user Just, can the emasculation cutter of more allowing blade replacement.

Background technology

Pear, in Rosaceae (Rosaceae) pears subfamily (Pomoideae) pear (Pyrus) plant, is worldwide main fruit One of tree, is also Chinese the third-largest fruit tree species.Originating in Chinese pear, Varieties is various, strong adaptability, and distribution is produced.China is existing Main breed is had mostly to be the improved variety of own intellectual property or traditional local varieties.In recent ten years, China is mainly bred as Emerald green hat, green, yellow hat worn by a Taoist priest early summer etc. several to have autonomous property right pears be all to be formed by the artificial hybridization selection-breeding of routine.Pear tree is conventional Artificial hybridization breeding need artificial emasculation, pollinate, cultivate the work such as pruning, character identification screening.

At present, artificial emasculation works, and is mainly operated by tweezers, shears or staff, utilizes tweezers or staff direct Pull out stamen, flower pesticide, or wipe out with shears, use tweezers to pull out efficiency low, the bad grasp of power, easily damages gynoecium；Make Higher by shears efficiency, but scope is controlled and is difficult to, and is the most easily damaged to gynoecium, and the blade of shears can not be individually replaced, Can only change whole shears, use cost is higher；And directly pulled out by staff, efficiency and accuracy are higher, however it is necessary that through The skilled worker crossing specialized training could accurately be pulled out, and workman also bears pollination work simultaneously, in emasculation step, and unavoidably can be by Pollen transmission on hand is in pistil.

Summary of the invention

To be solved in the utility model is exactly in current pear tree emasculation work, uses tweezers, shears and direct staff behaviour Make the inconvenience that brings, it is provided that a kind of easy to use, can the emasculation cutter of more allowing blade replacement.

Emasculation cutter of the present utility model, it is characterised in that this emasculation cutter includes handle of a knife and blade, handle of a knife is two, two cuttves Handle top is connected by screw, and two handle of a knifes rotate around junction point；Blade is two panels, is separately mounted to the inner side of two handle of a knifes, Blade back is provided with threaded rod, and handle of a knife upper position is threaded hole, and threaded rod matches with the screw thread of screwed hole, and blade is carried on the back The threaded rod in portion is fixing in penetrating the screwed hole of handle of a knife.

Described handle of a knife upper inner is additionally provided with anti-pinch gum cover, and anti-pinch gum cover protrudes from handle of a knife, prevents handle of a knife from closing completely Hold together rear tong.

Described handle of a knife bottom is also cased with rubber hands shield, when operation, holds rubber hands shield.Anti-skidding and protection can be played Effect.

Described blade is arc-shaped, and handle of a knife is provided with arc groove on the relevant position installing blade, and blade is arranged In groove.

Described threaded rod length is more than screwed hole length, it is simple to adjust the spacing of two panels blade, to adapt to different flower pattern.

The operator of emasculation work, pinch the handle of a knife of emasculation cutter, utilize the blade being provided with on emasculation cutter, can be easily Shear stamen and the flower pesticide of pear flower, easy to use, when after the blade blunt of blade, by rotating threaded rod, blade is taken off, i.e. Can be replaced.

Emasculation cutter of the present utility model, simple in construction, design science, easy to use, blade is arranged on cutter by threaded rod On handle, the spacing between two panels blade can be adjusted by threaded rod, it is simple to use, use threaded simultaneously, it is simple to change Blade, effectively reduces the replacement cost of instrument.
