Description

Technical Field

[0001] This utility model belongs to the field of greening plant maintenance technology, and in particular relates to an urban greening plant maintenance device. Background Technology

[0002] Urban greening plants can achieve a unity of ecological, social, and economic value. They can improve the urban environment and enhance the quality of life for residents. They can purify the air through photosynthesis, alleviate air pollution, stabilize the soil with their roots, reduce soil erosion, and relieve visual fatigue, soothe emotions, and reduce residents' anxiety. Green plants need regular maintenance to maintain their aesthetic appeal, but if they are not pruned regularly, they will lose their aesthetic value, affecting not only the city's appearance but also causing inconvenience to passing vehicles and pedestrians.

[0003] The shears used for maintaining green plants typically have fixed handle lengths. When encountering wider green belts, the limited handle length prevents them from reaching the inner plants, requiring workers to enter the green belt to trim those further away. This is particularly inconvenient due to the dense density of the green belts. Therefore, we propose a device for maintaining urban green plants. Utility Model Content

[0004] The purpose of this invention is to provide a device for maintaining urban green plants, so as to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a device for maintaining urban green plants, comprising: scissors, a handle, an upper protective sleeve and a lower protective sleeve, characterized in that a diagonal support plate is fixedly connected to one end of the scissors, a handle is fixedly connected to the upper part of the diagonal support plate, an extension tube is in contact with the outer surface of the handle, and a positioning mechanism is provided on the outside of the extension tube;

[0006] The upper sheath is fixedly connected to an upper retaining seat, and the lower sheath is fixedly connected to a lower retaining seat. The inner walls of the upper and lower retaining seats are in contact with the outer surface of the extension tube.

[0007] In this technical solution, the length of the shear body is increased by extending the tube, making it easier for staff to use and allowing them to prune distant green plants.

[0008] In the above technical solution, the lower card holder has four through holes inside, and the four through holes are located at the four corners of the lower card holder. The upper surface of the upper card holder is fixedly connected with a number of positioning rods equal to the number of through holes, and the outer surface of the positioning rods is in contact with the inner wall of the through holes.

[0009] In this technical solution, each of the four corners of the lower card holder is provided with a through hole, and the number of positioning rods of the upper card holder is the same as the number of through holes.

[0011] In this technical solution, knob two can rotate lead screw two through positioning hole one and positioning hole two.

[0012] In the above technical solution, a positioning pin is fixedly connected to the upper part of the lower sheath, and a positioning hole three is opened on the inner side of the upper sheath, with the outer surface of the positioning pin contacting the inner wall of the positioning hole three.

[0013] In this technical solution, the stability after the upper and lower sheaths are closed is improved.

[0014] In the above technical solution, a rubber handguard is further fixedly installed at the end of the extension tube away from the handle, and the rubber handguard is located inside the upper and lower protective sleeves.

[0015] In this technical solution, the friction force on the hand is increased to prevent the device from slipping out of the hand.

A limit block is rotatably connected to one end of the lead screw at the fixed seat, and one side of the limit block is in contact with the outer surface of the handle.

[0017] In this technical solution, the resistance of the grip is increased by moving the limiting block, and the stability is improved by fixing the grip.

[0018] In the above technical solution, further, a knob is fixedly connected to one end of the lead screw located outside the fixed seat, and a sliding groove is provided on the inner side of the extension tube, the inner wall of the sliding groove being in contact with the outer surface of the limiting block.

[0021] 1. This urban greening plant maintenance device, through the cooperation of the extension tube, handle and positioning mechanism, the extension tube and handle have a pull-out function. After the extension tube is pulled out, the positioning mechanism maintains the stability between the handle and the extension tube. By pulling the extension tube out from the outside of the handle, the pruning distance of the shear body is increased, which improves the convenience for workers to prune greening plants in wider green belts.

[0022] 2. This urban greening plant maintenance device, through the cooperation of the upper and lower protective sleeves, upper and lower card holders, and inclined support plate, creates a misalignment between the handle and extension tube and the greening plant, raising the hand above the plant and reducing the chance of contact between the hand and the plant, thereby reducing scratches caused by the plant to the hand. The upper and lower protective sleeves wrap the handle inside, protecting the hand when pruning the greening plant and further improving the safety of the worker's hand. Attached Figure Description

[0034] The upper sheath is fixedly connected to an upper retaining seat, and the lower sheath is fixedly connected to a lower retaining seat. The inner walls of the upper and lower retaining seats are in contact with the outer surface of the extension tube.

[0035] Among them, when pruning green plants, the increased height of the inclined support plate reduces the contact between the green plants and the hands during the pruning process, while the extension tube can extend the pruning distance to a certain extent. In order to prevent excessive extension or detachment, a positioning mechanism that can limit the length has been added.

[0036] Example 2: This example provides an urban greening plant maintenance device. In addition to the technical solution of the above example, it also has the following technical features: the lower card seat has four through holes inside, and the four through holes are located at the four corners of the lower card seat. The upper surface of the upper card seat is fixedly connected with a positioning rod of the same number as the through holes. The outer surface of the positioning rod is in contact with the inner wall of the through hole.

[0037] The through-hole inside the lower card holder and the positioning rod of the upper card holder prevent misalignment.

[0038] Example 3: This example provides an urban greening plant maintenance device.

[0039] The positioning hole 2 and lead screw 2 on the lower bracket prevent the upper and lower brackets from rotating or sliding, while the knob 2 facilitates turning the lead screw 2.

[0040] Example 4: This example provides an urban greening plant maintenance device. In addition to the technical solutions of the above examples, it also has the following technical features: a positioning pin is fixedly connected to the upper part of the lower sheath, a positioning hole three is opened on the inner side of the lower sheath, and the outer surface of the positioning pin is in contact with the inner wall of the positioning hole three.

[0041] The positioning pins fix the position and provide stability, making it easier to install and remove the upper and lower protective sleeves.

[0042] Example 5: This example provides an urban greening plant maintenance device. In addition to the technical solutions of the above examples, it also has the following technical features: a rubber hand guard is fixedly installed at the end of the extension tube away from the handle, and the rubber hand guard is located inside the upper and lower protective sleeves.

[0043] The protective sleeve reduces scratching of green plants when cutting, and a rubber hand guard is added to increase friction and prevent slippage.

[0044] Example 6: This example provides an urban greening plant maintenance device. In addition to the technical solutions of the above examples, it also has the following technical features: the positioning mechanism includes a fixed seat, one side of which is fixedly connected to the outer surface of the extension tube, and a lead screw is threadedly connected to the inner wall of the fixed seat. A limit block is rotatably connected to one end of the lead screw at the fixed seat, and one side of the limit block is in contact with the outer surface of the handle.

[0045] The positioning mechanism uses a fixed seat to connect the lead screw to the limiting block, preventing the extension tube from falling off the handle and controlling the length.

[0046] Example 7: This example provides an urban greening plant maintenance device. In addition to the technical solutions of the above examples, it also has the following technical features: a knob is fixedly connected to one end of the lead screw located outside the fixed base; a sliding groove is provided on the inner side of the extension tube; and the inner wall of the sliding groove is in contact with the outer surface of the limiting block.

[0047] Among them, the lead screw can move the position of the limit block by passing through the slide groove.

[0048] Working principle: When the green belt is wide, the scissors cannot reach the green plants. The overall length is increased by extending the tube, and the diagonal brace increases the distance between the hand and the green plants, reducing the contact between the hand and the green plants. By turning the knob of the extension tube positioning mechanism, the screw rod moves the position of the limit block. The limit block increases the resistance and friction on the handle, fixes the handle and increases stability.

[0049] To prevent hand injuries from plant cuts during pruning, upper and lower protective sleeves are used to enclose the hands, preventing contact with the plants. Positioning holes and pins are located inside the upper and lower sleeves to enhance stability and facilitate installation and removal. The upper and lower retainers are connected by positioning rods and through holes. First, place the upper retainer on the extension tube, then place the lower retainer on top. The positioning rods fix the position to prevent misalignment. Knob two is installed by rotating screw two; disassembly is performed by reversing the operation.
