Description

Technical Field

[0001] This utility model relates to the field of greening maintenance, and in particular to a garden greening maintenance and pruning device. Background Technology

[0002] Landscape greening refers to the ecological beautification and functional optimization of urban, community, and courtyard spaces through scientific planning and design, utilizing natural elements such as plants, water bodies, and topography, combined with artificial landscaping techniques. Its core includes planting trees, flowers, and lawns; creating landscape features; improving microclimates; purifying air; reducing noise; and providing recreational spaces. Landscape greening offers ecological, aesthetic, economic, and social benefits, and is an important means of improving the quality of the living environment, promoting biodiversity, and achieving sustainable development. It encompasses various forms such as parks, roadside greening, and rooftop gardens.

[0003] Most landscaping maintenance and pruning devices require maintenance personnel to operate them by hand, especially when pruning excess branches high up on trees. Maintenance personnel need to use pruning shears and climb to a suitable height with the help of a folding ladder to prune. In some cases, because some branches are located beyond the maximum climbing height of the folding ladder, the shears are not long enough to reach the branches, and maintenance personnel need to forcibly stick part of their body out. This behavior increases the danger in the maintenance process and reduces the practicality of the device.

[0004] Therefore, those skilled in the art have provided a garden greening maintenance and pruning device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a garden greening maintenance and pruning device. The device rotates the threaded rod at the upper end of the connecting part by twisting the first adjusting ring, which in turn causes the lifting cylinder sleeved on it to slide upward under the restriction of the limiting rod and the sliding groove. This causes the first connecting rod and the blade fixedly connected to the upper end of the lifting cylinder to slide as well, thus extending the overall pruning device. Subsequently, the handle can be gripped for more convenient pruning, reducing the danger of pruning and improving the practicality of the device.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A garden greening maintenance and pruning device includes an extension mechanism and a fixing mechanism. The lower end of the extension mechanism is rotatably connected to the fixing mechanism. The extension mechanism includes two connecting parts. A threaded rod is rotatably connected to the middle of the upper end face of each of the two connecting parts. A first adjusting ring is fixedly connected to the lower end of the outer wall of each of the two threaded rods. A lifting cylinder is sleeved on the outer wall of each of the two threaded rods. A handle is fixedly connected to the middle of one side end face of each of the two connecting parts. A limit rod is fixedly connected to the middle of the upper end face of each of the two handles. Multiple sliding grooves are opened around the outer wall of each of the two lifting cylinders. A first connecting rod is fixedly connected to the middle of the upper end face of each of the two lifting cylinders. A blade is fixedly connected to the upper end of each of the two first connecting rods.

[0008] Through the above technical solution, the device rotates the threaded rod at the upper end of the connecting part by twisting the first adjusting ring. This causes the lifting cylinder, which is threadedly connected to the lifting cylinder, to slide along the upper end of the threaded rod under the restriction of the limiting rod and the sliding groove. Consequently, the first connecting rod fixedly connected to the upper end of the lifting cylinder and the blade fixedly connected to the first connecting rod also slide, thus extending the overall length of the trimming device. This allows for more convenient trimming by holding the handle, eliminating the need for maintenance personnel to extend their bodies to shorten the trimming distance. It also reduces the danger during trimming and improves the practicality of the device.

[0009] Furthermore, the fixing mechanism includes a rotating groove, and a snap-fit ​​groove is provided at the lower end of one side end face of one of the connecting parts. A rotating block is hinged in the middle of the rotating groove. A spring telescopic rod is fixedly connected to one end of the rotating block. A connecting cylinder is fixedly connected to one end of the spring telescopic rod. A second connecting rod is rotatably connected to one end of the connecting cylinder. Both sides of the outer wall of the second connecting rod are fixedly connected with snap-fit ​​blocks. A second adjusting ring is fixedly connected to one end of the outer wall of the second connecting rod.

[0010] Through the above technical solution, the device rotates the rotating block and other components in the rotating groove to a horizontal position. Then, it pulls the connecting cylinder at one end of the spring telescopic rod to insert the second connecting rod and its locking block into the groove shape on the locking groove. Finally, it rotates the second adjusting ring 90 degrees in any direction, causing the second connecting rod and locking block to rotate and embed into the groove in the locking groove. The connecting cylinder is then released, and the pulling force of the spring telescopic rod is used to fix the locking block tightly against the groove on the inner wall of the locking groove, thus reducing the risk of being cut when touched and improving the practicality of the device.

[0011] Furthermore, an abutment block is fixedly connected to the middle of the upper part of one side end face of each of the two lifting cylinders;

[0012] Through the above technical solution, this setting enables the trimming device to keep the blade closed properly when closed, avoiding misalignment and damage to the blade.

[0013] Furthermore, one side of the outer wall of each of the two lifting cylinders is slidably connected to a limiting rod, and one side of the outer wall of each of the multiple sliding grooves is slidably connected to a limiting rod;

[0014] The above technical solution makes the sliding of the lifting cylinder more stable and prevents it from deviating from the sliding trajectory.

[0015] Furthermore, both of the lifting cylinders are threadedly connected to the threaded rod;

[0016] The above technical solution enables the lifting cylinder to slide along the thread when the threaded rod rotates.

[0017] Furthermore, the length of each of the aforementioned grooves is less than the length of the threaded rod;

[0018] Through the above technical solution, this setting ensures that the lifting cylinder will not block the first adjusting ring when it retracts, thus preventing the rotation of the first adjusting ring from being affected.

[0019] Furthermore, a rotating groove is provided at the lower end of one side end face of one of the connecting parts, and the volume of the rotating block is smaller than the spatial volume of the rotating groove;

[0020] Through the above technical solution, this setting enables the rotating block and its components to rotate smoothly and provides sufficient space for stretching and fixing.

[0021] Furthermore, a groove is formed in the middle of one side of the inner wall of the snap-fit ​​groove, and its shape is consistent with that of the snap-fit ​​block and the second connecting rod after combination;

[0022] Through the above technical solution, this setting allows the connecting cylinder 205 at one end of the spring telescopic rod 204 to insert its second connecting rod 206 and its locking block 207 into the groove shape on the locking slot 202.

[0023] This utility model has the following beneficial effects:

[0024] 1. The present invention proposes a garden greening maintenance and pruning device. The device rotates the threaded rod at the upper end of the connecting part by twisting the first adjusting ring. This causes the lifting cylinder connected to the threaded rod to slide along the upper end of the threaded rod under the restriction of the limiting rod and the sliding groove. Consequently, the first connecting rod fixedly connected to the upper end of the lifting cylinder and the blade fixedly connected to the first connecting rod also slide, thereby extending the overall length of the pruning device. Then, the handle can be held for more convenient pruning. This eliminates the need for maintenance personnel to extend their bodies to shorten the pruning distance, reduces the danger during pruning, and improves the practicality of the device.

[0025] 2. The present invention proposes a garden greening maintenance and pruning device. The device rotates the rotating block and other components in the rotating groove to a horizontal position. Then, the connecting cylinder at one end of the spring telescopic rod is pulled to insert the second connecting rod and its locking block into the groove on the locking groove. Finally, the second adjusting ring is rotated 90 degrees in any direction to make the second connecting rod and the locking block rotate and embed into the groove in the locking groove. The connecting cylinder is then released, and the pulling force of the spring telescopic rod is used to fix the locking block tightly against the groove on the inner wall of the locking groove, thus reducing the risk of being cut when touched and improving the practicality of the device.

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of specific embodiments. Obviously, the described specific embodiments are only a part of the specific embodiments of the present invention, and not all of them. Based on the specific embodiments of the present invention, all other specific embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Reference Figure 1-3 One specific embodiment provided by this utility model:

[0035] A garden greening maintenance and pruning device includes an extension mechanism 1 and a fixing mechanism 2. The lower end of the extension mechanism 1 is rotatably connected to the fixing mechanism 2. The extension mechanism 1 includes two connecting parts 101. Threaded rods 102 are rotatably connected to the middle of the upper end face of each of the two connecting parts 101. First adjusting rings 103 are fixedly connected to the lower ends of the outer walls of each of the two threaded rods 102. Lifting cylinders 104 are sleeved on the outer walls of each of the two threaded rods 102. Handles 106 are fixedly connected to the middle of one side end face of each of the two connecting parts 101. Limiting rods 107 are fixedly connected to the middle of the upper end face of each of the two handles 106. Multiple sliding grooves 108 are formed around the outer walls of the two lifting cylinders 104. First adjusting rings 103 are fixedly connected to the middle of the upper end face of each of the two lifting cylinders 104. The upper ends of the two first connecting rods 109 are fixedly connected to blades 110. The device rotates the threaded rod 102 at the upper end of the connecting part 101 by twisting the first adjusting ring 103. This causes the lifting cylinder 104, which is threadedly connected to it, to slide along the upper end of the threaded rod 102 under the restriction of the limiting rod 107 and the sliding groove 108. Consequently, the first connecting rod 109 fixedly connected to the upper end of the lifting cylinder 104 and the blades 110 fixedly connected to the first connecting rod 109 also slide, thus extending the overall length of the trimming device. This allows for more convenient trimming by holding the handle, eliminating the need for maintenance personnel to extend their bodies to shorten the trimming distance, reducing the danger during trimming, and improving the practicality of the device.

[0036] Reference Figure 3-5 The fixing mechanism 2 includes a rotating groove 201. A snap-fit ​​groove 202 is formed at the lower end of one side face of a connecting part 101. A rotating block 203 is hinged to the center of the rotating groove 201. A spring telescopic rod 204 is fixedly connected to one end of the rotating block 203. A connecting cylinder 205 is fixedly connected to one end of the spring telescopic rod 204. A second connecting rod 206 is rotatably connected to one end of the connecting cylinder 205. Locking blocks 207 are fixedly connected to both sides of the outer wall of the second connecting rod 206. A second adjusting ring 208 is fixedly connected to one end of the outer wall of the second connecting rod 206. The device rotates the rotating block within the rotating groove 201. 203 and its other components are brought to a horizontal position. Then, the connecting tube 205 at one end of the spring telescopic rod 204 is pulled to insert the second connecting rod 206 and its locking block 207 into the groove shape on the locking groove 202. Finally, the second adjusting ring 208 is rotated 90 degrees in any direction to make the second connecting rod 206 and the locking block 207 rotate and embed into the groove in the locking groove 202. The connecting tube 205 is then released, and the pulling force of the spring telescopic rod 204 is used to fix the locking block 207 tightly against the groove on the inner wall of the locking groove 202, thus reducing the risk of being cut when touched and improving the practicality of the device.

[0037] Abutment block 105 is fixedly connected to the middle of the upper part of one side end face of each of the two lifting cylinders 104. This arrangement ensures that the blades are properly closed when the trimming device is closed, preventing them from being misaligned and damaged.

[0038] One side of the outer wall of each of the two lifting cylinders 104 is slidably connected to the limiting rod 107, and one side of the outer wall of each of the multiple sliding grooves 108 is slidably connected to the limiting rod 107. This arrangement makes the sliding of the lifting cylinders 104 more stable and prevents them from deviating from the sliding trajectory.

[0039] Both lifting cylinders 104 are threadedly connected to the threaded rod 102, which allows the lifting cylinders 104 to slide along the thread when the threaded rod 102 rotates.

[0040] The lengths of the multiple grooves 108 are all less than the length of the threaded rod 102. This arrangement ensures that the lifting cylinder 104 will not abut against the first adjusting ring 103 when it retracts, thus affecting the rotation of the first adjusting ring 103.

[0041] One of the connecting parts 101 has a rotating groove 201 on the lower end of one side end face. The volume of the rotating block 203 is smaller than the volume of the rotating groove 201. This arrangement allows the rotating block 203 and its components to rotate smoothly and provides sufficient space for stretching and fixing.

[0042] The inner wall of the snap-fit ​​groove 202 has a groove in the middle of one side, which is consistent with the shape of the snap-fit ​​block 207 and the second connecting rod 206. This arrangement allows the connecting tube 205 at one end of the spring telescopic rod 204 to insert the second connecting rod 206 and the snap-fit ​​block 207 on it into the groove along the shape of the groove on the snap-fit ​​groove 202.

[0043] Working principle: The device rotates the threaded rod 102 at the upper end of the connecting part 101 by twisting the first adjusting ring 103. This causes the lifting cylinder 104, which is threaded to it, to slide along the upper end of the threaded rod 102 under the restriction of the limiting rod 107 and the sliding groove 108. Consequently, the first connecting rod 109 fixedly connected to the upper end of the lifting cylinder 104 and the blade 110 fixedly connected to the first connecting rod 109 also slide, extending the overall length of the trimming device. This allows for more convenient trimming by gripping the handle. The device rotates the rotating groove... The rotating block 203 and other components on it in 201 are brought to a horizontal position. Then, the connecting tube 205 at one end of the spring telescopic rod 204 is pulled to insert the second connecting rod 206 and the locking block 207 on it into the groove shape on the locking groove 202. Finally, the second adjusting ring 208 is rotated 90 degrees in any direction to make the second connecting rod 206 and the locking block 207 rotate and embed into the groove in the locking groove 202. The connecting tube 205 is then released and the pulling force of the spring telescopic rod 204 is used to fix the locking block 207 tightly against the groove on the inner wall of the locking groove 202.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing specific embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
