Description

Gardening shears linkage cutting structure

This creation is about a kind of "gardening shears linked cutting structure", especially a kind of gardening shears linked to cutting structure that is held by both hands and used to trim flowers and trees.

According to the current known gardening shears, most of them have two opposite cutting blades. A long rod-shaped handle is installed under the cutting blades, and a perforation is provided in the middle section. The perforation provides a locking knot through which the nut matches the screw. , The two cutting blades can be pivoted and positioned. When a force is applied to the handle, the perforation can be used as the axis to make the cutting blades open and close, so as to use the two shears The blade opens and closes to cut.

However, the above-mentioned conventional structure still has the following problems in practical applications: the openings that the gardening shears can open are limited, so the gardening shears cannot be used for pruning thick branches and leaves, nor can they A force-increasing effect is obtained through the expansion of the opening angle of the cutting blade, which makes the gardening shears more laborious to use, and is easy to be limited by the thicker branches and leaves and cannot be used smoothly.

Therefore, how to develop and improve the shortcomings of the above-mentioned conventional gardening shears is actually the goal of the relevant industry's efforts. In view of this, the creator has thought and created ideas, so he designed it with years of experience , After many discussions and trial sample tests, and many revisions and improvements, this creation is released.

The conventional gardening shears cannot obtain a force-increasing effect by expanding the opening angle of the cutting blade. This is the technical problem to be solved.

This creation provides a linkage cutting structure for gardening shears, which includes: a first knife board, a second knife board, an operating handle and a protective sheet, wherein a first cutting part is provided above the first knife board, The middle section is provided with a first hole, and a first tooth part protrudes from the side of the first hole below the first shearing part, so that the first tooth part provides the second tooth part on the operating handle as Engage, and a handle is combined under the first knife plate, a second shearing part is arranged above the second knife plate, a second hole is arranged in the middle section, and a third hole is arranged below the second knife plate. Leaning on one side surface of the first knife board, so that a first pivotal member is used to penetrate the second hole and the first hole at the same time, so that the second knife board can be mounted on the first knife board. A pivot group is obtained from the upper part. Through the relationship of the pivot group, the second blade can be rotated out or in by the second shearing portion relative to the first shearing portion of the first blade, thereby To achieve the effect of opening and closing shearing, a driving plate is provided above the operating handle, the center of the driving plate penetrates a fourth hole, and the top edge is provided with a second tooth part. The operating handle is based on the second tooth part and the first tooth part. After the first tooth portion of the blade is engaged, a second pivotal member is inserted into the third hole and the fourth hole at the same time, so as to use the penetration of the second pivotal member to allow the operating handle It can be pivotally connected on the second knife board, the protective sheet has a body, and two opposite positions on the periphery of the body protrude with an ear, and the A fifth hole and a sixth hole are respectively penetrated on the two ears. The protective sheet is attached to the other side surface of the first knife board which is different from the second knife board, so as to be in place. When the first knife board, the second knife board, and the operating handle are pivotally assembled, the fifth hole is used to simultaneously provide the first pivot member to penetrate, and the sixth hole to simultaneously provide the second pivot member to penetrate. The protective sheet can also be pivoted between the first blade plate and the driving plate of the operating handle. The installation of the protective sheet also enables the protective sheet to cooperate with the second blade to perform the operation The driving plate of the handle is clamped and limited, so that the operating handle can be reliably and stably assembled between the second knife plate and the protective sheet, so as to obtain a gardening shears linkage cutting structure.

(1) This creation provides a linkage shearing structure for gardening shears. The linkage shearing structure of gardening shears can provide thicker cut objects for trimming and increase the cutting force. It should be less expensive to use. Time-saving, labor-saving and comprehensive.

(2) This creation provides a linkage shearing structure for gardening shears, which utilizes the installation of the protective sheet to make the pivoting of the operating handle more stable, and can also prevent the operating handle from being cut too hard. That is, those who produce abnormal shaking or displacement.

(3) This creation provides a linkage shearing structure for gardening shears, which uses the separation of the protective sheet to prevent the operating hand from being too close to the meshing part of the first tooth part and the second tooth part, and not being Be careful of the injured.

(4) This creation provides a linkage cutting structure for gardening shears. The protective sheet can reinforce the pivotal structure of the first blade, the second blade and the operating handle, so that the overall strength of the gardening shears can be significantly improved Promoter.

(5) This creation provides a linkage shearing structure for gardening shears. The protective sheet uses the extension of the two ears to effectively disperse the force, so as to prevent the stress under shearing from being concentrated on a single point. The shears are likely to be damaged.
