Description

Gardening shears linkage structure

This creation is about a "gardening shears linkage structure", especially a gardening shears linkage structure that provides a grip for pruning flowers, plants and trees.

According to the current knowledge, most garden shears have two opposing shear blades. A long rod-shaped handle is installed below the shear blades. A through hole is provided in the middle section. The through hole provides a lock for a nut to pass through with a screw, so that the two shear blades can be positioned relative to each other. When force is applied to the handle, the shear blades can be opened and closed with the through hole as the axis, so that the opening and closing of the two shear blades can be used for shearing.

However, the known structure described above still has the following problems in practical application: the garden shears directly use the hinge of the screw as a fulcrum, and cannot produce the force-enhancing effect of the lever, so that the garden shears still have the problem of being more laborious to use. The two shear blades are only hinged together by the screw, and the two shear blades are prone to shaking with each other, and the stability during shearing is relatively poor.

Therefore, how to develop and improve the shortcomings of the above-mentioned conventional garden shears is indeed a goal that the relevant industry needs to work hard on. In view of this, the creator of this product has come up with the idea of creating a product based on his years of experience. After many discussions and sample tests, as well as many revisions and improvements, this product was launched.

It is known that garden shears cannot produce the force-increasing effect of a lever, and have poor stability during shearing. This is the technical problem that we want to solve.

The invention provides a garden shears linkage structure, which includes: a first shearing unit, a knife anvil, a second shearing unit, a latch and a number of hinges, and the second shearing unit has a knife plate, a driving member, two connecting rods and two limit plates, wherein the first shearing unit has two knife anvil plates, each of which is penetrated by an arc-shaped long hole, a first hole of the knife anvil plate and a second hole of the knife anvil plate, and the knife anvil is clamped by the two knife anvil plates, and a accommodating space can be separated by the knife anvil between the two knife anvil plates so that the accommodating space The second shearing unit is provided as an accommodation, a notch is formed at the lower side of one side of the blade plate, and a first blade hole and a second blade hole are respectively provided on the upper and lower sides of the notch, and two convex parts are provided above the driving member to keep the left and right separated, and a first driving member hole and a second driving member hole are respectively penetrated on the two convex parts, and a first connecting rod hole and a second connecting rod hole are respectively penetrated near the two ends of the connecting rod. When the two connecting rods are against the two side surfaces of the blade plate and the driving member, and the latch is inserted in the second connecting rod hole of the connecting rod, the connecting rod hole is opened. The driving member and the connecting rod are connected smoothly by using a pivot member to continuously penetrate the arc-shaped long holes of the two knife anvil plates, the connecting rod first holes of the two connecting rods and the knife plate first hole of the knife plate, and the driving member can swing along the arc-shaped long holes in the accommodation space through the connecting rod when subjected to force, so as to synchronously drive the knife plate to open and close during the swinging process. The limiting plate is penetrated by a first limiting plate hole and a second limiting plate hole. When the two limiting plates are close to each other, the limiting plate is closed. When the two side surfaces of the knife plate and the driving member are pressed against each other, the first hole of the limiting plate will be aligned with the first hole of the two knife plates and the second hole of the driving member, and the second hole of the limiting plate will be aligned with the second hole of the two knife plates and the second hole of the knife plate, so that the two hinges can be inserted from the first hole of the knife plate and the second hole of the knife plate to smoothly install the second shearing unit in the accommodation space, thereby obtaining a garden shears linkage structure.

(I) This invention provides a linkage structure for gardening shears, which can produce a lever force-enhancing effect during linkage shearing, and can also provide pruning for thicker objects to be sheared, which is more time-saving, labor-saving and comprehensive in use.

(II) This invention provides a garden shear linkage structure, which utilizes the installation of the limit plate and the connecting rod to make the shearing action of the driving member and the blade more stable, and can also prevent the driving member from shearing with excessive force, that is, causing abnormal shaking or displacement.

(III) This invention provides a linkage structure for gardening shears. The limiter can reinforce the installation of the blade and the driver, and can also effectively disperse the force, so that the overall strength of the gardening shears can be significantly improved.

A first blade hole (312) and a second blade hole (313) are respectively provided above and below the notch (311) to penetrate the blade plate (31). Two convex parts (321) are provided above the driving member (32) to keep the left and right sides separated. A first driving member hole (322) and a second driving member hole (323) are respectively penetrated through the two convex parts (321). A first connecting rod hole (331) and a second connecting rod hole (332) are respectively penetrated through the connecting rod near both ends. When the two connecting rods (33) are against the two side surfaces of the blade plate (31) and the driving member (32), the connecting rod (33) is connected to the blade plate (31) and the driving member (32). When the latch (40) is inserted into the second hole (332) of the connecting rod and the first hole (322) of the driving member, the driving member (32) and the connecting rod (33) can be smoothly connected. The hinge (50) is continuously inserted into the arc-shaped long holes (111) of the two knife and chopping boards (11), the first holes (331) of the two connecting rods (33), and the connecting rods (33). ) and the first hole (312) of the knife plate (31), and the driving member (32) can be rotated along the arc-shaped long hole (111) in the accommodating space (12) through the connecting rod (33) when subjected to force, so as to synchronously drive the knife plate (31) to open and close during the rotation process. The limiting plate (34) is penetrated by a first hole (341) of the limiting plate and a limiting hole (342). The second hole (342) of the positioning plate, when the two limiting plates (34) are against the two side surfaces of the knife plate (31) and the driving member (32), the first hole (341) of the limiting plate will be aligned with the first hole (112) of the knife plate (11) and the second hole (323) of the driving member (32), and the second hole (342) of the limiting plate will be aligned with the second hole (113) of the knife plate (11) and the second hole (313) of the knife plate (31), so that the two pivot members (50) can be inserted through the first hole (112) and the second hole (113) of the knife plate to enable the second shearing unit (30) to be smoothly installed in the accommodating space (12).
