The middle part of the lower clamp is upwards bent to form a longitudinal arched slot, the front part of the lower clamp is provided with a guide slot which has a high front part and a low back part, the longitudinal cutting blade arranged in the guide slot can freely slide in the slot, the lower end of the guide slot is provided with bud holes, and the tail part of the lower clamp is provided with a handlebar.

Description

Bud grafting device

The utility model relates to a kind of instrument when carrying out plant graft, is mainly used in the vegetative bud grafting operation of trees, flowers and other plants.

Present people carry out vegetative propagation bud grafting operation to trees such as fruit tree, flowers and other plants and generally use budding knife, when carrying out the bud grafting operation with budding knife, bud that is cut and stock are cut the main armrest strength of size of mouth and are grasped, even the veteran also difficulty make budder, stock cutting face depth size is consistent, both can not be fully identical, influence graft survival rate, this traditional grafting operating speed is slow, inefficiency.

The purpose of this utility model provides a kind of bud grafting instrument, be used for cutting the grafting bevel of getting on bud (scion) and the stock, make the bevel size depth basically identical of the bevel of buddering and stock, both can well coincide after the grafting, improve survival rate, and easy to use, improve the operating efficiency of grafting operation.

The utility model mainly is made up of last folder (1) and following folder (2) two parts.Up-bow in the middle of the following folder, formation one is deep-slotted chip breaker (3) longitudinally, and the front portion of groove is slightly shallow, the rear portion is slightly dark, forms certain gradient, and there is support (5) upwards both sides, following folder middle part, the support upper end is porose, for upper and lower folder connecting axle (9) usefulness, shock mount on the connecting axle (11) are installed; Following folder is anterior to be equipped with the guide groove (4) of rip cutting blade feed, and the guide groove rear end is rip cutting blade feed position, and germ pore (6) is located at down the rear portion of folder.

Both sides, last folder middle part also are provided with support (5), and the support upper end is porose, use for installing down the folder connecting axle, the anterior mounting spring steel disc of last folder (8), rip cutting blade (12) is installed at the spring steel plate rear portion, on press from both sides the rear portion crosscut blade (10) be installed, the installation position and the germ pore rear portion correspondence of folder down.

The utility model advantage is, be used for cutting getting and budder and on stock, cut the face of connecing, guarantee their size and depth basically identical, make the xylem and the fully combination of phloem of buddering with stock, thereby raising graft survival rate, when using it to carry out grafting, operating speed is obviously accelerated, and can raise labour efficiency.

In the accompanying drawing: (1) goes up folder; (2) press from both sides down; (3) deep-slotted chip breaker; (4) guide groove; (5) support; (6) germ pore; (7) handle; (8) spring steel plate; (9) connecting axle; (10) crosscut blade; (11) spring; (12) rip cutting blade.

Further be illustrated again below in conjunction with accompanying drawing: be down the dark deep-slotted chip breaker in a preceding shallow back in the middle of the folder, during use deep-slotted chip breaker is stuck on the branch, get to make when buddering and cut bud and the petiole got and from germ pore (6), expose, press the back handle of folder up and down after firmly good, at this moment the crosscut blade (10) of going up the folder rear portion is along front portion that the incision of germ pore rear end is buddered, reaching needs the degree of depth, unclamp the rear portion of folder again, be subjected to the effect of spring (11), press from both sides the front end closure up and down, the spring steel plate (8) of folder front end in the drive, promotion rip cutting blade vertically cuts bud to leave branch or vertically cut one on stock and connects face.

Crosscut blade and rip cutting blade have been made two kinds, a kind of band xylem of buddering that cuts, and the blade edge of a knife is all used straight, and when cutting buddering of getting when not being with xylem, the blade of rip cutting blade is an arc, and it is curved that the crosscut blade is used edge of a knife up-bow instead.

Accompanying drawing is schematic diagram of the present utility model.

Claims

1, the bud grafting device used of a kind of grafting, it is characterized in that by last folder (1) and press from both sides (2) down forming, up-bow in the middle of the following folder, form vertical deep-slotted chip breaker (3), all there is support (5) Jia both sides, middle part up and down, and the support upper end is porose, use for installing down folder connecting axle (9), mounting spring on the connecting axle (11), the anterior guide groove (4) of installing of following folder, germ pore (6) is located at down the rear portion of folder; The anterior mounting spring steel disc of last folder (8), spring steel plate rear portion are installed rip cutting blade (12), on press from both sides the rear portion crosscut blade (10) be installed.

2, as the said bud grafting device of claim 1, the blade that it is characterized in that rip cutting blade (12) also can be an arc, and the edge of a knife of crosscut blade (10) also can be curved to up-bow.
