Description

Multi-purpose scissors for cutting branches and pruning {agricultural scissors for cutting branches}

The present invention relates to multi-purpose scissors for fruit and pruning used in fruit farming, when thinning fruit (fruit work), pruning fruit trees, removing overgrown side branches, or removing branches (pruning work). More specifically, it relates to scissors. The new shape of the blade makes cutting and pruning easier, and the blade for removing side branches can be attached and detached from the side of the tip of the pole to provide multi-purpose scissors that enable more convenient and efficient cutting and pruning work. will be.

Conventional cutting or pruning shears have a fixed scissors blade and a movable scissors blade attached to the tip of the pole. The fixed scissor blade is attached to the pole with the blade tip facing longitudinally from the pole tip, and the movable scissors blade is attached to the side of the fixed scissors blade. By connecting it with a hinge shaft, the movable part of the movable scissor blade is attached to the operating rod installed in the pole, and the movable scissor blade is opened and closed by pulling and pushing the operating rod with the operating lever installed on the handle. The blades of the movable scissors blades are formed parallel to the length of the pole, so the blades of the fixed and movable scissors blades open and close in a direction perpendicular to the length of the pole. Therefore, when cutting or pruning fruit, the tip of the scissors blades is placed between the fruits. It is not easy to put it into the fruit tree, which makes it inconvenient to cut and prune the fruit. In addition, the side branches growing on the surface of the fruit tree cannot be easily removed, so there is the inconvenience of having to use a separate tool.

Prior Art Patent Registration No. 10-1837730

The present invention was developed to improve the above inconvenience.

In the present invention, the scissors blade attached to the pole tip is formed of a fixed scissors blade and a movable scissors blade, and the fixed scissor blade protrudes a certain length so that the tip of the attached protrusion piece is bent upward from the pole tip attachment portion to form a bent protruding piece, From the outer periphery of the upper end of the bent protrusion piece, an inclined blade is formed that slopes downward at a certain angle toward the tip of the pole and has a sharp end. Then, the inclined blade portion and the concave blade portion are formed separately on the inclined blade plate to form the red and fore branch portions separately, By attaching a movable scissors blade to the side of the bending protrusion so that the blade of the movable scissor blade contacts the inclined blade portion of the fixed blade to the concave blade portion, the blade of the movable scissor blade is inclined at a certain angle with the longitudinal direction of the pole tip. By engaging the inclined blade and concave blade of the fixed scissors blade to form a cutting and pruning, a blade is formed on the outer surface of the fixed scissors blade attachment part at the tip of the pole, and a side branch removal blade that bends concavely toward the handle is attached to make it removable. , It is designed to be a multi-purpose scissors that can conveniently remove side branches and cut and prune fruit.

In the present invention, the fixed scissor blade attached to the tip of the pole is bent to protrude a certain length upward from the tip of the attached stone piece fixed to the tip of the pole, forming a downward slope with a certain angle from the outer periphery of the protruding bent protrusion toward the tip of the pole. After forming the inclined blade plate, the inclined blade portion and the concave blade portion are formed so that the cutting portion and the front branch portion are formed along the inclined surface of the inclined blade portion, and since the blade of the movable blade is brought into contact with the inclined blade portion and the concave blade portion, it is attached to the tip of the pole. The scissor blades are formed to be inclined at a certain angle like the beak of a ferricana bird, which has the advantage of making it easier to insert the blades into the red widow or pruning section, and cutting tree branches with ease. The inclined blades have a bevel at the end. Since the cutting part with a sharp blade is arranged and the pruning part with a concave blade is arranged on the inside, the fruit can be cut using the tip of the blade when pruning, and the pruning can be done using the inside of the blade, making it an effective cutting and pruning machine. Work becomes possible.

In addition, in the present invention, the operating distance between the operating protrusions of the movable blade and the operating lever can be selected using an operating distance adjusting device attached to the operating lever, so when applying, the angle at which the movable blade is opened and closed is adjusted. Narrow selection is possible, and pruning can be selected to have a large opening and closing angle of the movable blade, so there is an advantage of being able to work more efficiently by selecting the opening and closing angle of the movable scissor blade according to the type of work.

In addition, since the present invention is configured to attach a blade for removing side branches to the attachment portion of the fixed scissor blade at the tip of the pole, when cutting a side branch, the operation of the movable scissor blade is stopped and the blade for removing side branches is fixed. It can be used by attaching it to the attachment part of the scissor blade or the attachment part on the opposite side, which provides the advantage of convenient side branch removal work.

In particular, when attaching the blade for side branch removal, loosen only the bolts on both sides from the threaded holes formed on the fixed scissor blade attachment stone piece, align the attachment hole of the side branch removal blade attachment section with the screw holes on both sides of the fixed scissor blade attachment stone piece, and then attach the fixed scissors blade. Assemble the fixing bolt of the blade by screwing, or loosen the bolt screwed into the second attachment hole of the attachment part formed on the opposite side of the pole tip, and connect the attachment hole of the attachment part of the blade for side branch removal to the second attachment hole and the screw hole of the screw hole plate. Since it can be attached by screwing in bolts, it has the advantage of being able to be selectively attached to both sides of the tip of the pole, allowing the blade to be attached and used according to the direction in which the side branches grow. When not in use, it can be detached from the attachment part. It has the advantage of being able to be stored and reattached when in use.
