Abstract

The invention relates to an agricultural tool and can be used in horticulture for grafting plants. The purpose of the invention is to expand the technological capabilities of the clamp due to the copulation of cuttings of different diameters. The clamp includes two clamping jaws 1 and 2 with longitudinal working surfaces and a device for adjusting the mutual position of the jaws 1 and 2, / V containing guides and means for adjusting the movement of the jaws. The clamping jaws are located in the clamp so that their flat surfaces form a common upper guide plane M inclined to the longitudinal line of the jaws, and the slots made in the jaws form a common slit 4 allowing the longitudinal splitting of the handle. At least one of the working surfaces of the clamping jaws is made in the form of two planes 5 and b, intersecting along a line parallel to the longitudinal line of the jaws.

4 for longitudinal splitting of the cutting. The working surface of the other sponge can be made flat or cylindrical, but with a large radius. To prepare for grafting, the stalk is placed in a nest formed by the working surfaces of the sponges, the stalk is compressed for reliable fixation with the sponges and, using the M plane as a guide, make a cut

cutting. After that, if necessary, make the splitting of the cutting, putting the knife in the slot 4 until it stops. Due to the shape of the working surfaces of the sponges, damage to the cuttings is eliminated and the ratio of the diameter of the cutting to the distance between the plane of the longitudinal splitting and the cutting parallel to it diametrically is ensured. 2 Il.

The invention relates to an agricultural tool and can be used in horticulture for grafting plants.

The aim of the invention is the expansion of technological capabilities due to the copulation of cuttings of different diameters.

FIG. 1 shows the jaws forming the clamp; in fig. 2 - view of the clamping sponge along arrow A.

The proposed clamp includes two clamping jaws 1 and 2 with longitudinal working surfaces and a device for adjusting the mutual position of the jaws 1 and 2, containing guides made, for example, in the form of pins (not shown) and the means for adjusting the movement of the jaws , made, for example, in the form of screw-type studs (not shown).

The clamping jaws are located in the clamp in such a way that the special flat surfaces on them form a common upper guide plane 3, inclined to the longitudinal line of the jaws at an angle y, and the slots made in these jaws form a common slot 4, allowing the longitudinal splitting of the handle. The working surface of at least one of the jaws is made in the form of two planes 5 and 6 intersecting along a line parallel to the longitudinal line of the jaws, and the bisector plane of the dihedral angle D formed by two planes 5 and 6 is inclined to the plane in which the slit 4 for longitudinal splitting of the cutting, at an angle a.

The working surface of the other clamping jaw can be mirrored first (as shown in Fig. 1) can be flat or slightly concave (along a cylinder of large radius).

The clip for grafting plants works as follows.

The cuttings of the plants are placed in the nest formed by the working surfaces of the cusps, squeezed to secure the cutting of the cuttings with sponges and, for example, using a grafting knife, using a cutting 3 as a guide, cut the cutting and, if necessary, after cutting cut, knife produced, do not remove the stalk from the nest, splitting the stalk. For this, the knife is inserted into slot 4 as far as it will go.

The device provides high operational reliability and high-quality execution of the operations required for vaccination when changing the diameters of the cuttings over a wide range. Due to the shape of the working surfaces of the sponges, despite the change in the diameters of the cuttings over a wide range (the contours of the cuttings are shown by the circumferences in Fig. 1), damage to the bark of the cuttings is eliminated and, the distance from the plane of longitudinal splitting to the diameter of the plane of each cutting is maintained, the same) remains constant angle a.
