Description

Technical Field

[0001] The invention relates to the field of pruning equipment, in particular to pruning equipment for gardening projects. Background Art

[0002] The construction of garden projects requires the use of pruning knives to prune branches in the garden. The existing pruning knives cannot retract and fix the blades after use. When moving or storing, the blades are exposed, which not only easily injures the user but also collides with external objects and causes damage, which is inconvenient for the user to use.

[0003] To solve the above problems, after searching, a Chinese patent with announcement number CN216722198U discloses a pruning device for garden engineering, which includes a pruning knife body, a first connecting block, a second connecting block, a clamping plate, a knob, an open groove, a screw rod, a pushing sleeve, a clamping block and a clamping groove, wherein the first connecting block and the second connecting block are respectively arranged at the top and the bottom of the inner side of the pruning knife body, the first connecting block and the second connecting block are respectively fixedly connected to the pruning knife body, the clamping plate is fixedly connected to the top of the second connecting block, the knob is arranged on the right side of the first connecting block, the open groove is arranged inside the first connecting block, the screw rod is fixedly connected to the left side of the knob, the left side of the screw rod penetrates into the inside of the open groove, the screw rod is movably connected to the inner wall of the first connecting block, the pushing sleeve is threadedly connected to the surface of the screw rod, the clamping block is fixedly connected to the left side of the pushing sleeve, the clamping groove is arranged at the bottom of the first connecting block, and the clamping groove is communicated with the open groove;

[0030] Specific implementation method 1: Please refer to Figure 1-Figure 8 The present invention provides a technical solution: a pruning device for garden engineering, comprising a pruning seat 1, a fixed knife 52 is fixedly installed on the top of the pruning seat 1, a fixed rod 2 is fixedly installed on the end of the pruning seat 1 away from the fixed knife 52, an extension rod 3 is fixedly installed on the end of the fixed rod 2 away from the pruning seat 1, a handle 4 is fixedly arranged at the bottom of the extension rod 3, a pruning mechanism 5 is installed on the pruning seat 1, a shearing knife 50 is arranged on the pruning mechanism 5, a driving wheel 53 is fixedly installed on the bottom of the shearing knife 50, a driven gear 54 is arranged below the driving wheel 53, a rotating shaft is fixedly installed on the driven gear 54, the rotating shaft passes through the pruning seat 1 through a bearing and is fixedly connected to the driving gear 55.

[0031] Working principle: When using it, when it is necessary to cut high branches, hold the handle 4 with the left hand, place the opening position of the shearing knife 50 and the fixed knife 52 on the high branch that needs to be cut, and then push the starting column 59 upward, the operating column 581 squeezes the spring 57 through the squeezing sheet 58, and at the same time drives the rack 551 to move upward to drive the driving gear 55 to rotate counterclockwise, and the driving gear 55 drives the driven gear 54 to rotate counterclockwise, and the counterclockwise rotation of the driven gear 54 can drive the driving wheel 53 meshing with it to rotate clockwise. , the shearing knife 50 rotates clockwise to reduce the angle between it and the fixed knife 52 to cut the high branches of the garden, and can achieve the cutting work of the branches and leaves of the high trees; the angle between the shearing knife 50 and the fixed knife 52 can be flexibly adjusted according to the position and growth angle of the high branches, so as to better adapt to the high branches of different directions and shapes, improve the accuracy and convenience of cutting, and avoid repeated adjustments or failure to cut smoothly due to poor angles; the use of the lever principle makes it easier for operators to cut high branches; compared with other relatively rigid or inflexible cutting methods, it can reduce the physical consumption of operators, so that the cutting work can be completed more efficiently, improve work efficiency, save time and labor costs; by accurately controlling the rotation angle of the shearing knife, the high branches can be cut more accurately, only the parts that need to be pruned are removed, and the damage to other healthy parts of the trees is minimized; it is helpful to heal the wounds of the trees, reduce the risk of trees being infected with diseases and pests, and protect the growth and health of the trees; when the high branches are cut, the starting column 59 is released, and the compressed spring 57 is reset and rebounded, so that the driving gear The rack 551 moves downward, and the driving wheel 53 is driven to move away from the fixed knife 52 through the driving gear 55 and the driven gear 54, so that the angle between the fixed knife 52 and the shearing knife 50 increases, and a cutting cycle of a group of high branches is completed; when the driving rack 551 is lifted, the guide seat 5521 at the bottom is plugged into the inside of the guide rail 552, which can limit and guide the driving rack 551 during lifting, ensuring the stability of the driving rack 551 during lifting, preventing it from tilting, and avoiding the driving rack 551 from disengaging from the driving gear 55;

[0032] The shear knife 50 and the fixed knife 52 are both set in a "C" shape, and the inner sides of the shear knife 50 and the fixed knife 52 are fixedly provided with a blade 51. When cutting branches and leaves, the "C"-shaped blade 51 has a larger contact area with the branches and leaves, which can better fit the shape of the branches and leaves, especially for some irregularly shaped branches and leaves, and can also achieve more accurate cutting, avoiding the situation that the blade 51 slips or the cutting position is inaccurate, so that the pruning position and degree can be controlled more accurately; the two "C"-shaped blades 51 are relatively arranged, and can form a hug-like action when shearing, forming a two-way cutting force on the branches and leaves. Compared with a single-edged shear knife, it is easier to cut thicker branches and leaves, reducing the number of shearing times and improving work efficiency; because the "C"-shaped blade 51 can evenly apply pressure on the branches and leaves, the cuts after cutting are smoother and brighter The "C"-shaped blade 51 is easy to cut and can be easily cut into pieces. The "C"-shaped blade 51 is easy to cut and can be easily cut into pieces. The "C"-shaped blade 51 is easy to cut and can be easily cut into pieces. The "C"-shaped blade 51 is easy to cut and can be easily cut into pieces.

The tops of the shearing knife 50 and the fixed knife 52 are both set in an arc shape; the circumferential outer walls of the shearing knife 50 and the fixed knife 52 are streamlined in design;

[0036] The curved top can more gently contact the branches and surrounding leaves of the tree during pruning, reducing accidental damage to non-pruned parts, helping to protect the health of the tree, promoting wound healing, and reducing the risk of infection; whether during pruning operations or when the tool is idle, the curved top can prevent sharp corners from catching other objects, such as other plants in the garden, making operations smoother and reducing damage to the surrounding environment; the curved design can better fit branches of different thicknesses and shapes, and can more tightly surround the branches during pruning, making the cutting action more stable and accurate, improving the quality and effect of pruning, and ensuring a smooth incision; the streamlined outer wall can prevent debris, dust, or branch and leaf debris from getting stuck in the seams of the tool The tool can avoid gaps or bumps to keep the tool clean and run smoothly, reducing operation interruptions and damage to the blade caused by jamming; the curved top and streamlined outer wall can cleverly avoid surrounding leaves when the tool is moving between branches and leaves, reducing the chance of scratching healthy leaves; like some plants with delicate and easily damaged leaves, ordinary tools can easily scratch the leaves, affecting the appearance and plant growth, and this type of design can avoid such situations and ensure the integrity of the plants; there are stomata on the surface of the leaves, which are responsible for breathing and transpiration; if scratched by tools, the stomata will be damaged, which will interfere with the normal physiological activities of the plants; this design can prevent scratches, ensure the integrity of the leaf stomata, maintain good gas exchange and water regulation capabilities of the plants, and help the plants thrive.
