Technical Field

[0001] This utility model relates to the field of landscaping technology, specifically to an adjustable landscaping tree pruning device. Background Technology

[0002] As an important part of urban construction and ecological environmental protection, landscaping has received increasing attention from all sectors of society. However, the maintenance and management of landscaping, especially the pruning of trees, is an important task. In order to improve the efficiency of tree pruning, corresponding pruning equipment is usually used.

[0003] For example, CN220875184U discloses a garden tree pruning device, specifically relating to the field of pruning devices. It includes a main body, a telescopic mechanism, and a protective mechanism. The main body is equipped with a telescopic mechanism, and the telescopic mechanism is equipped with a protective mechanism. The telescopic mechanism is movably connected to the main body, and the protective mechanism is fixedly connected to the telescopic mechanism. The worker holds a handle with one hand and grips the handle with the other to stabilize the device. A second motor is activated to drive a rotating shaft, which in turn moves the blade to the desired pruning position for trimming. The protective cover prevents the blade from injuring the worker, improving protection.

[0004] The existing technology has the following technical problems: When the existing pruning device is in use, it uses a saw blade to prune tree branches. However, when not in use, the saw blade is exposed. When the staff picks up the pruning device, the exposed saw blade can easily cause injury to the staff. At the same time, it is not convenient to fix the tree branches to be pruned during pruning. When the saw blade cuts the branches, it can easily cause the tree branches to shake, thus affecting the overall pruning effect.

[0005] Therefore, we propose an adjustable tree pruning device for landscaping to address the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide an adjustable garden tree pruning device to solve the problems mentioned in the background art. Existing pruning devices on the market use saw blades to prune tree branches, but the saw blades are exposed when not in use. When workers pick up the pruning device, the exposed saw blades can easily cause injury. At the same time, it is not convenient to fix the tree branches to be pruned during pruning. When the saw blade cuts the branches, it can easily cause the tree branches to shake, thus affecting the overall pruning effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an adjustable garden tree pruning device, comprising a gripping rod, a first motor fixedly mounted at the end of the gripping rod, and a pruning saw blade fixedly connected to the output end of the first motor, the pruning saw blade being used to cut tree branches, a movable frame mounted at the end of the gripping rod, a guide screw threaded through the middle of the movable frame, the end of the guide screw being rotatably connected to the gripping rod, a second motor fixedly mounted at the upper end of the movable frame, a central screw connected to the output end of the second motor, and a protective cover mounted on the central screw, the protective cover being used to shield and protect the pruning saw blade, a guide rod threaded through the end of the protective cover, and the guide rod being fixedly mounted on the movable frame.

[0008] Preferably, the grip bar includes a first branch bar, a second branch bar, and a sweat-absorbing and anti-slip sleeve, wherein the second branch bar is installed on the first branch bar, and the sweat-absorbing and anti-slip sleeve is fitted on the second branch bar.

[0009] By adopting the above technical solution, the sweat-absorbing and anti-slip sleeve can play a role in absorbing sweat and preventing slippage when the staff holds the second branch pole.

[0010] Preferably, the first branch rod and the second branch rod are threaded together, and the middle part of the first branch rod is set as a hollow structure.

[0011] By adopting the above technical solution, the lengths of the first branch rod and the second branch rod can be easily adjusted through the threaded connection of the first branch rod and the second branch rod.

[0012] Preferably, the outer wall of the movable frame and the inner wall of the end of the first branch rod are in contact with each other, and the movable frame and the first branch rod are slidably connected, while the middle part of the movable frame and the guide screw are threadedly connected.

[0013] By adopting the above technical solution, the stability of the movable frame when moving on the first branch rod can be improved by the mutual contact between the outer wall of the movable frame and the inner wall of the first branch rod.

[0014] Preferably, the protective covers are symmetrically arranged about the transverse central axis of the movable frame, and the symmetrically distributed protective covers are all threadedly connected to the central screw.

[0015] By adopting the above technical solution, the protective cover of the threaded connection can be moved and adjusted by rotating the guide screw.

[0016] Preferably, the threads at the upper and lower ends of the central screw have opposite directions.

[0017] By adopting the above technical solution, the reverse thread of the guide screw enables the two symmetrically distributed protective covers to move synchronously relative to each other.

[0018] Preferably, the inner wall of the end of the protective cover and the outer wall of the guide rod are in contact with each other, and the protective cover can move on the guide rod.

[0019] By adopting the above technical solution, the movement of the protective cover on the guide rod can prevent the protective cover from rotating synchronously with the central screw.

[0020] Compared with the prior art, the beneficial effects of this utility model are: the adjustable garden greening tree pruning equipment can conveniently adjust the overall length of the pruning equipment according to the height of the tree branches during use, and can also shield and protect the saw blade when it is not necessary to cut the tree branches, and can clamp and fix the tree branches when pruning the tree branches.

[0021] 1. It is equipped with a sweat-absorbing and anti-slip sleeve. The sweat-absorbing and anti-slip sleeve on the second branch rod can increase the friction between the staff's palm and the second branch rod when the staff holds the second branch rod, thereby increasing the stability of the second branch rod when it is held.

[0022] 2. A first branch rod is provided, and a threaded connection is made between the second branch rod and the first branch rod, so that the length between the endpoints of the first branch rod and the second branch rod can be adjusted when the second branch rod rotates, thereby adjusting the length of use according to the height of different tree branches;

[0023] 3. Equipped with protective covers, the two protective covers can move synchronously relative to each other under the action of the reverse threads at the ends by rotating the central screw. The relative movement of the two protective covers can cover or open the pruning saw blade, thereby protecting the pruning saw blade when carrying the pruning equipment and preventing the exposed pruning saw blade from causing injury to the workers.

[0024] 4. A movable frame is provided. By rotating the guide screw, the movable frame can be moved on the first branch rod, so that the protective cover on the movable frame can be moved to the side of the pruning saw blade. At this time, when pruning tree branches, the relative movement of the two protective covers can also clamp the tree branches, ensuring the stability of the branches during pruning.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1: Please refer to Figures 1-6 Existing pruning devices use saw blades to prune tree branches during use, but the saw blades are exposed when not in use. When workers handle the pruning equipment, the exposed saw blades can easily cause injury. To solve this technical problem, this embodiment discloses the following technical content: an adjustable garden tree pruning device, including a gripping rod 1, a first motor 2 fixedly installed at the end of the gripping rod 1, and a pruning saw blade 3 fixedly connected to the output end of the first motor 2. The pruning saw blade 3 is used to cut tree branches. A movable frame 4 is installed at the end of the gripping rod 1, and a guide screw 5 is installed through the middle of the movable frame 4. The end of the guide screw 5 is rotatably connected to the gripping rod 1, and a second motor 6 is fixedly installed at the upper end of the movable frame 4. A central screw 7 is connected to the output end of the second motor 6, and a protective cover 8 is installed on the central screw 7. The protective cover 8 is used to shield and protect the pruning saw blade 3. A guide rod 9 is installed through the end of the protective cover 8 and is fixedly installed on the movable frame 4. The protective covers 8 are symmetrically arranged about the transverse central axis of the movable frame 4, and all symmetrically distributed protective covers 8 are threadedly connected to the central screw 7. The threads at the upper and lower ends of the central screw 7 run in opposite directions. The inner wall of the end of the protective cover 8 and the outer wall of the guide rod 9 fit together, and the protective cover 8 can move on the guide rod 9.

[0034] When carrying the pruning equipment, the symmetrically distributed protective covers 8 can shield and protect the pruning saw blade 3, preventing the exposed pruning saw blade 3 from causing injury to the workers during transport. At the same time, when it is necessary to prune the tree branches, the second motor 6 is turned on. The turning of the second motor 6 causes the central screw 7 to rotate. The rotation of the central screw 7 causes the two protective covers 8 to move synchronously relative to each other through the reverse thread. The movement of the protective covers 8 opens the pruning saw blade 3. Then, the worker holds the gripping rod 1 and turns on the first motor 2, which drives the pruning saw blade 3 to rotate. The rotation of the pruning saw blade 3 is used to prune the tree branches.

[0035] Example 2: The technical content disclosed in this example is a further improvement based on Example 1. During pruning, it is not convenient to fix the branches of the tree to be pruned. When the saw blade cuts the branches, it is easy to cause the branches to shake, thus affecting the overall pruning effect. In order to further solve this technical problem, this example discloses the following technical content: the outer wall of the movable frame 4 and the inner wall of the end of the first branch rod 101 are in contact with each other, and the movable frame 4 and the first branch rod 101 are slidably connected. The middle part of the movable frame 4 and the guide screw 5 are threadedly connected.

[0036] Before pruning tree branches, the guide screw 5 is rotated. After the guide screw 5 rotates, the threaded movable frame 4 can move on the first branch rod 101, so that the movable frame 4 drives the protective cover 8 to move to the side of the pruning saw blade 3. When pruning tree branches, the second motor 6 controls the central screw 7 to rotate. The rotation of the central screw 7 can then clamp and fix the tree branches to be pruned through the protective cover 8, thereby improving the stability of the branches when pruning them.

[0037] Example 3: The technical content disclosed in this example is a further improvement based on Example 1. This example discloses the following technical content: the grip bar 1 includes a first branch bar 101, a second branch bar 102, and a sweat-absorbing anti-slip sleeve 103. The second branch bar 102 is mounted on the first branch bar 101, and the sweat-absorbing anti-slip sleeve 103 is fitted onto the second branch bar 102. The first branch bar 101 and the second branch bar 102 are threaded together, and the middle part of the first branch bar 101 is a hollow structure.

[0038] By rotating the second branch rod 102 on the first branch rod 101, since the first branch rod 101 and the second branch rod 102 are connected by a thread, the rotation of the second branch rod 102 can adjust the distance between the endpoints of the first branch rod 101 and the second branch rod 102, thereby adjusting the length of the trimming equipment according to actual needs.

[0039] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0040] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing 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 invention should be included within the protection scope of the present invention.
