[0008] The shearing unit includes a fixed cover, an upper blade, and a lower blade; the fixed cover is fixed to the bottom of the operating lever; the middle section of the upper blade is fixed to the fixed cover by a first fixing member; the upper blade is angled to the bottom of the operating lever; the tail section of the upper blade is provided with an elongated hole, and a slider is slidably disposed in the elongated hole; the middle section of the lower blade is hinged to the upper blade by a hinge shaft; a second pull rod is hinged to the tail of the lower blade, and the end of the second pull rod is hinged to the slider; a third pull rod is also hinged to the slider, and the end of the third pull rod is hinged to the bottom end of the first pull rod; an upper clamping plate is fixedly disposed above the upper blade, and a lower clamping plate is disposed above the lower blade;

[0009] Under normal conditions, the shear section is in the open position.

[0010] Furthermore, the tail of the upper blade is fixed to the fixing cover by a second fixing member.

[0011] Furthermore, the tail section of the upper blade is provided with a hinge seat, and a fourth pull rod is hinged to the hinge seat. The end of the fourth pull rod is hinged to the lower middle part of the third pull rod.

[0012] Furthermore, the angle between the upper blade and the bottom of the operating lever is 0°-60°.

[0013] Furthermore, the opposing sides of the upper and lower clamping plates are both serrated.

[0014] This utility model has the following beneficial effects:

[0015] This utility model integrates pruning and clamping functions, enabling convenient pruning and removal of lodged, diseased, and withered aquatic plants. Maintenance personnel can perform these tasks standing or sitting on the water's edge or from a boat, reducing the number of times they need to squat, bend over, or enter the water, thereby improving the level of refined aquatic plant maintenance and work efficiency.

Detailed Implementation

[0021] To achieve the above objectives and effects, the technical means and structure adopted by this utility model are described in detail with reference to the accompanying drawings, focusing on the features and functions of the preferred embodiments of this utility model.

[0022] like Figure 1-4 As shown, this utility model provides aquatic plant gardening shears, including an operating rod 4 and handles and cutting parts disposed at both ends of the operating rod 4;

[0023] The operating lever 4 has a hollow structure, and a first pull rod 3 is inserted inside the operating lever 4;

[0024] The handle includes an upper handle 1 and a lower handle 2. The upper handle 1 is fixed to the top of the operating lever 4. The lower handle 2 is hinged to the upper handle 1, and a torsion spring is provided at the hinge point between the lower handle 2 and the upper handle 1. The top end of the first pull rod 3 is hinged to the lower handle 2.

[0025] The shearing section includes a fixed cover 5, an upper blade 8, and a lower blade 11. The fixed cover 5 is fixed to the bottom of the operating lever 4. The middle section of the upper blade 8 is fixed to the fixed cover 5 by a first fixing member 6. The upper blade 8 is set at an angle to the bottom of the operating lever 4. The tail section of the upper blade 8 is provided with an elongated hole, and a slider 14 is slidably disposed in the elongated hole. The middle section of the lower blade 11 is hinged to the upper blade 8 by a hinge shaft 13. The tail of the lower blade 11 is hinged to a second pull rod 12, and the end of the second pull rod 12 is hinged to the slider 14. A third pull rod 15 is also hinged to the slider 14, and the end of the third pull rod 15 is hinged to the bottom end of the first pull rod 3. An upper clamping piece 9 is fixedly disposed above the upper blade 8, and a lower clamping piece 10 is disposed above the lower blade 11.

[0026] In another embodiment, the tail of the upper blade 8 is fixed to the fixing cover 5 by a second fixing member 7 to improve the stability of the shearing part.

[0027] In another embodiment, the tail section of the upper blade 8 is provided with a hinge seat 16, and a fourth pull rod 17 is hinged to the hinge seat 16. The end of the fourth pull rod 17 is hinged to the lower middle part of the third pull rod 15. By providing the fourth pull rod 17, a lever is formed, making the operation more labor-saving.

[0028] In another embodiment, the angle between the upper blade 8 and the bottom of the operating lever 4 is 0°-60°, so that the cutting part can be parallel to the horizontal plane during operation, which is convenient for trimming.

[0029] In another embodiment, the opposing sides of the upper clamping piece 9 and the lower clamping piece 10 are both serrated to facilitate the clamping of pruned branches and leaves and prevent them from falling off.

[0030] Under normal conditions, the shearing section is in the open position. During operation, maintenance personnel can perform maintenance on aquatic plants standing or sitting on the water's edge or while on a boat. Holding the handle, the personnel position the shearing section roughly parallel to the horizontal plane, aligning the shearing cut with the branch or leaf of the aquatic plant to be pruned. Pulling the lower handle 2 upwards rotates it towards the upper handle 1, causing the first lever 3 to move upwards. As the first lever 3 moves upwards, it pulls the third lever 15 and the fourth lever 17, connecting... The force between the rods reduces the angle between the third pull rod 15 and the fourth pull rod 17. Driven by the third pull rod 15, the slider 14 slides along the elongated hole towards the operating rod 4, thereby moving the second pull rod 12 towards the operating rod 4. Driven by the second pull rod 12, the lower blade 11 rotates around the hinge axis 13, reducing the angle between the lower blade 11 and the upper blade 8, thus pruning the aquatic plant. Simultaneously, the angle between the upper clamping plate 9 and the lower clamping plate 10 decreases, securing the aquatic plant. After pruning, the clamping force between the upper clamping plate 9 and the lower clamping plate 10 allows the operating rod 4 to be moved, transferring the pruned aquatic plant branches and leaves.

[0031] Release the lower handle 2. Under the elastic force of the torsion spring, the lower handle 2, the first pull rod 3, the third pull rod 15, the fourth pull rod 17, the second pull rod 12, the upper blade 8, the lower blade 11, the upper clamp 9, and the lower clamp 10 return to their original positions. The pruned aquatic plant branches and leaves detach from between the upper clamp 9 and the lower clamp 10.

[0032] The above description is only a preferred embodiment of the present utility model and not all embodiments. Anyone should know that structural changes made under the guidance of the present utility model are protected by the present utility model. All technical solutions that are the same as or similar to the present utility model are within the scope of protection of the present utility model.
