Description

Technical Field

[0001] This utility model relates to the field of garden pruning tools, and in particular to a high branch shears. Background Technology

[0002] Gardening shears are one of the most commonly used tools in garden pruning. They are mainly used to prune branches, flower branches, hedges, etc., to maintain the healthy growth and beautiful shape of plants. Among them, high branch shears are a tool specifically designed for pruning branches.

[0003] However, traditional pruning shears often use a one-to-one direct power transmission method, which is extremely strenuous for users and increases labor intensity. Secondly, the shear mechanism of traditional pruning shears often lacks a steering function. When encountering dense foliage and branches intertwined in different directions, users can only raise their arms or bend over deeply, frequently adjusting the position and angle of the pruning shears to adapt, which is extremely inconvenient and can easily cause physical strain. In addition, traditional pruning shears often use nylon ropes or ordinary steel ropes to pull the blades. These materials wear out very quickly under frequent friction and stress, requiring frequent replacement, which not only affects pruning efficiency but also increases usage costs.

[0012] 1. This utility model achieves a stable connection between round rod one and round rod two by setting up telescopic components, fixed sleeve two and fixed sleeve three, providing reliable support for the overall structure. Secondly, the ingenious combination of long rod, mounting frame one and fixed wheel provides a fixed winding point for steel rope one, ensuring effective force transmission. In addition, the design of movable mounting frame two in conjunction with moving wheel one and moving wheel two can amplify the force through steel rope one transmission, greatly reducing the user's operating resistance, making the pruning process easier and less strenuous, and significantly improving the convenience and comfort of operation.

[0013] 2. This utility model, by setting a steering component and the threaded connection between the screw and the nut, can flexibly adjust the distance between the movable seat and the fixed seat, and precisely control the engagement state of the first and second locking teeth, thereby realizing the flexible locking and free rotation of the movable seat angle. Secondly, the spring can release elastic potential energy when the nut is loosened, pushing open the fixed seat and the movable seat, so that the first and second locking teeth separate. When tightened, the spring is compressed, so that the first and second locking teeth engage. This makes the movable seat angle adjustment operation simple and stable, and can easily meet the needs of cutting branches in different directions. When the scissor assembly forms a 90-degree angle with the first and second round rods, if the user needs to cut branches on the ground, he can point the scissor assembly downwards and pull the movable handle to easily carry out the cutting operation without bending over.

[0014] 3. This utility model integrates sawing and shearing functions by setting up a scissor assembly and installing a sleeve to provide a mounting base for the long saw blade. The long saw blade can cut larger branches. Secondly, the movable mounting bracket 2 and the connecting piece 1 drive the movable mounting bracket 3 to slide within the round rod 2. The sprocket changes the transmission direction of the chain 1 and further amplifies the operator's force, thereby driving the chain 2 to open and close the scissor blade 1. It works in conjunction with the scissor blade 2 fixed on the movable seat to complete the pruning. At the same time, the power transmission of the sprocket, chain 1 and chain 2 is stable and not easy to wear, extending the service life of the high-branch shears. In addition, the return spring provides a return force to the scissor blade 1 after pruning, ensuring the smooth progress of the next pruning. The overall assembly is feature-rich, operates smoothly, and can efficiently complete various pruning tasks. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0026] like Figures 1-9 As shown, this utility model proposes a high-branch pruner, which includes a round rod 1. The round rod 1 serves as the main support structure of the high-branch pruner, providing a mounting base for other components. A fixing sleeve 2 is provided at the tail of the round rod 1. The fixing sleeve 2 is used to limit the sliding range of the movable handle 3 and prevent it from coming off. At the same time, it serves as the tail fixing point of the steel rope 34. The steel rope 34 limits the reset position of the movable handle 3. The movable handle 3 is slidably mounted on the round rod 1. The movable handle 3 can slide along the round rod 1. By manually operating the user, pulling the internal steel rope 410 triggers the telescopic component 4 and the shearing component 6 to perform the pruning operation. A round rod 7 is provided inside the round rod 1. The round rod 7 provides a mounting base for the steering component 5 and the shearing component 6. The telescopic component 4 is provided inside the round rod 1 and the round rod 7. The steering component 5 is provided at the top of the round rod 7. The shearing component 6 is provided on the steering component 5.

[0027] The telescopic assembly 4 includes a fixing sleeve 2 41 disposed inside the round rod 1. The tail of the round rod 2 7 is connected to the round rod 1 via the fixing sleeve 2 41. The fixing sleeve 2 41 connects the round rod 1 and the tail of the round rod 2 7, and also fixes the position of the long rod 43. A fixing sleeve 3 42 is disposed between the top of the round rod 1 and the round rod 2 7. The long rod 43 is disposed in the middle of the fixing sleeve 2 41. A mounting bracket 1 44 is disposed on the top of the long rod 43. The long rod 43 and the mounting bracket 1 44 provide a mounting base for the fixed wheel 45 and support the fixed winding point of the steel cable 1 410. The fixed wheel 45 is disposed on the mounting bracket 1 44. The fixed pulley 45 changes the running direction of the steel rope 410 to achieve force transmission. The movable mounting frame 46 is movably installed inside the round rod 7. The movable mounting frame 46 slides inside the round rod 7, driving the moving pulley 47 and the moving pulley 48 to move. The force is amplified through the transmission of the steel rope 410. The moving pulley 47 and the moving pulley 48 are installed on the movable mounting frame 46. The moving pulley 47 and the moving pulley 48 cooperate with the fixed pulley 45 to change the path of the steel rope 410, amplify the user's operating force, and reduce operating resistance. The top of the movable mounting frame 46 is equipped with a connector 49.

[0028] The inner side of the active handle 3 is equipped with fixing block 1 31, fixing block 2 32 and fixing block 33.

[0029] A steel rope 410 is installed inside the round rod 2 7. The head of the steel rope 410 is installed on the fixed block 2 32. The steel rope 410 passes through the fixed sleeve 3 42 along the round rod 1 1, and enters through the square hole on the round rod 2 7 on one side of the fixed sleeve 3 42. It then winds around the moving wheel 1 47, the fixed wheel 45, the moving wheel 2 48 and the fixed sleeve 2 41 in sequence. The tail of the steel rope 410 is located inside the fixed sleeve 3 42. The steel rope 410 connects the movable handle 3 and the movable mounting bracket 2 46. Through the winding path, the linear movement of the movable handle 3 is converted into the sliding of the movable mounting bracket 2 46, realizing the transmission and amplification of force. A steel rope 34 is installed on the outer wall of the round rod 1 1. The head of the steel rope 34 is located on the fixed block 3 33 and the tail of the steel rope 34 is located at the bottom of the fixed sleeve 1 2. The steel rope 34 connects the movable handle 3 and the fixed sleeve 1 2, limiting the reset position of the movable handle 3 and preventing it from rising excessively.

[0030] The steering assembly 5 includes a support base 51 located at the top of the round rod 7. The support base 51 provides a mounting base for other components in the steering assembly 5. A screw 52 is located in the middle of the support base 51, and a nut 53 is threaded to one end of the screw 52. The screw 52 and the nut 53 are connected by threads, which can adjust the distance between the movable seat 55 and the fixed seat 54 and control the engagement state of the first locking tooth 57 and the second locking tooth 58. A fixed seat 54 is located on the side of the support base 51 away from the nut 53. The fixed seat 54 serves as the reference for the rotation of the movable seat 55. A locking tooth 57 is located on one side of the fixed seat 54, and a movable seat 55 is located on the outer side of the fixed seat 54. The movable seat 55 can rotate around the screw 52. The movable seat 55 is equipped with a second locking tooth 58 corresponding to the position of the first locking tooth 57, and the first locking tooth 57 and the second locking tooth 58 lock together and separate to lock the angle of the movable seat 55 and allow it to rotate freely. One end of the screw 52 is connected to the movable seat 55, and a spring 56 is sleeved on the outside of the screw 52. One end of the spring 56 is connected to the fixed seat 54, and the end of the spring 56 away from the fixed seat 54 is connected to the movable seat 55. When the nut 53 is loosened, the spring 56 releases its elastic potential energy, pushing the fixed seat 54 and the movable seat 55 apart, so that the first locking tooth 57 and the second locking tooth 58 separate. When the nut 53 is tightened, the spring 56 is compressed, so that the first locking tooth 57 and the second locking tooth 58 lock together.

[0031] The scissor assembly 6 includes a fixed cylinder 61 mounted on a round rod 7, which provides a fixing point for the chain 69. A mounting sleeve 62 is fitted onto the top of the round rod 7, providing a mounting base for the long saw blade 610 and enabling sawing. A movable mounting bracket 63 is positioned inside the round rod 7 corresponding to the mounting sleeve 62. The movable mounting bracket 63 slides inside the round rod 7, driving the chain 65 to move and opening / closing the scissor blade 66. A sprocket 64 is mounted on the movable mounting bracket 63, changing the transmission direction of the chain 69 to transmit and amplify force. A chain 65 is mounted on the top of the movable mounting bracket 63, connecting the movable mounting bracket 63 and the scissor blade 66, enabling the opening and closing of the scissor blade 66. The chain 65 moves away from the movable mounting bracket. A shear blade 66 is installed at one end of the three-section rod 63. A shear blade 67 is installed on one side of the shear blade 66. The shear blade 67 is mounted on the movable seat 55. The shear blade 66 is opened and closed by the chain 65. It works with the shear blade 67 fixed on the movable seat 55 to complete the pruning. The shear blade 66 is connected to the movable seat 55 by a return spring. After the pruning is completed, the return spring provides the shear blade 66 with a return force to prepare for the next pruning. A chain 69 is installed inside the round rod 7. One end of the chain 69 is connected to the connector 49 and passes around the sprocket 64. The tail of the chain 69 is fixed inside the fixed cylinder 61. The chain 69 and the sprocket 64 work together to further amplify the force used by the operator. A long saw blade 610 is installed on one side of the mounting sleeve 62. The long saw blade 610 is used to saw off larger branches.

[0032] In use, the user holds the movable handle 3 and moves it towards the tail of the round rod 1. During this movement, the movable handle 3 pulls the steel cable 410, which, through the moving wheel 47, fixed wheel 45, and moving wheel 48, changes its path, amplifying the force and reducing the user's operating resistance. This causes the movable mounting frame 46 to move towards the tail along the inner wall of the round rod 7. The movable mounting frame 46 then moves the connecting piece 49 towards the tail along the inner wall of the round rod 7, pulling the chain 69. The chain 69 then pulls the movable mounting frame 63 towards the tail along the inner wall of the round rod 7. The tail moves, thereby driving the chain 65 to close the shear blades 66 and 67, thus pruning the branch. At this time, the return spring between the shear blade 66 and the movable seat 55 is stretched due to the closing action of the shear blade 66. After pruning, the user releases the movable handle 3, the return spring rebounds, and the shear blade 66 returns to its original position. At the same time, the steel rope 34 limits the handle to prevent the movable handle 3 from rising excessively when the return spring rebounds. When the user encounters a large branch, the long saw blade 610 on the side of the mounting sleeve 62 can be aligned with the large branch and sawed off forcefully.

[0033] When the user needs to cut branches vertically, the user can loosen the nut 53, and the spring 56 releases its elastic potential energy to push the movable seat 55 outward, causing the second locking tooth 58 on the movable seat 55 to separate from the first locking tooth 57 on the fixed seat 54. The user can then rotate the movable seat 55 to change the angle between the movable seat 55 and the scissor assembly 6 mounted on it and the second round rod 7. After adjustment, the user can tighten the nut 53 in the opposite direction, and the screw 52 moves towards the fixed seat 54, compressing the spring 56, so that the first locking tooth 57 and the second locking tooth 58 engage, thus fixing the position of the movable seat 55 and the scissor assembly 6 mounted on it, preventing the movable seat 55 from rotating accidentally during use. The user can then pull the movable handle 3 to easily cut branches vertically. At the same time, the user can also point the scissor assembly 6 downward and pull the movable handle 3 to quickly cut branches on the ground without bending over, reducing the physical strain caused by the user frequently raising their arms or bending over to cut branches, and improving the efficiency of pruning operations.
