Abstract

The utility model relates to a portable grafting device, which comprises a left pincers port with a pincers handle and a right pincers port with a pincers handle, wherein, the left pincers port and the right pincers port are connected by a shaft pin. The utility model is characterized in that the working faces of the two pincers ports are provided with branch clamping grooves, one of the branch clamping grooves of one pincers port is penetrated with a pressure lever, a spring is arranged at the inner end of the pressure lever, and a guillotine sheet is arranged on one pincers port. The utility model has the advantages of simple and convenient operation, labor saving, low labor intensity, high grafting quality, high labor efficiency, small volume, light weight and low price.

Description

Portable grafting device

The utility model belongs to the fruit-tree grafting utensil, particularly a kind of portable grafting device.

Grafting is the routine techniques of production of fruit trees, the method of grafting is more, the grafting in early spring, especially grafting high and changing head, often select overlap joint, the field overlaps at present, can only use grafting knife, the method that adopts hand to cut is although this grafting method is more simple than other method, but the specification requirement to the operator is also very high, it is consistent with the angle of inclination of scion otch to reach stock, and otch is straight, smooth, if the each cutting angle of operator is inconsistent or firmly inhomogeneous, will cause the otch varying length, actinal surface is rough and uneven in surface, so that reduces grafting quality and survival rate, even skilled orchard worker, also be difficult to guarantee the quality requirement that overlaps, the phenomenon of doing over again is often to occur.When grafting was very busy, an orchard worker will connect the hundreds of strains of seedling every day, at the end of the day, and stress, the arm fatigue after stock and the scion colligation, also will use lopping to cut, long scion is partly cut off, and the frequent substitution that grafting knife and lopping are cut in the grafting process is not only required great effort but also time-consuming.Once developed the seedling grafting machine abroad, though also can cut fast to decide angle, but it is to be power with compressed air, needs external power supply, and complex structure, volume is big, carrying inconvenience can only be in grafting, can not be in the field grafting, moreover grafting machine involves great expense, and is difficult to be accepted by the domestic user.

The purpose of this utility model provides a kind of portable grafting device, easy and simple to handle laborsaving, labour intensity is low, grafting quality height, the efficiency height, volume is little, and is in light weight, cost is low.

The purpose of this utility model is achieved in that it comprises by what pivot pin connected and has left jaw and a right jaw that clamps handle, it is characterized in that: folder branch groove is arranged on the working face of two jaws, install depression bar in the folder branch groove of a jaw, there is spring the inner of depression bar, and the chopper sheet is housed on a jaw.

Operation principle: during cutting, clamp branch with the folder branch groove of two jaws, depression bar is owing to the effect of spring, and branch is withstood in its end, prevents to rotate, and meanwhile the chopper sheet downcuts branch.

The utility model has the advantages that: easy and simple to handle laborsaving, labour intensity is low, grafting quality height, and the efficiency height, volume is little, in light weight, and price is low.

Below in conjunction with accompanying drawing the utility model is done into explanation down:
