DETAILED DESCRIPTION

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 and Figure 2 As shown, a tree pruning device for landscape gardening includes a telescopic mechanism 1, a gripping mechanism 2 is fixedly connected to the lower portion of the outer surface of the telescopic mechanism 1, a fixing mechanism 4 is fixedly connected to the upper portion of the telescopic mechanism 1, a pruning knife 3 is fixedly connected to the inner surface of the upper portion of the telescopic mechanism 1, and a traction mechanism 5 is fixedly connected to the lower portion of the pruning knife 3.

[0025] During the operation of the device in this solution, the branches to be pruned are fixed by the cooperation of the two fixed half rings 42, and then the pruning knife 3, the gripping mechanism 2 and the traction mechanism 5 are cooperated to cut, and at the same time, the telescopic tube 12 can be used to freely pruned high branches.

[0026] Similarly, during the specific implementation of the device in this solution, the shape and size of the trimming knife 3 can be redesigned and replaced according to the actual usage scenario without affecting the normal implementation of this solution.

[0027] See Figure 4 The telescopic mechanism 1 includes a telescopic tube 12, a spring 11 is fixedly connected to one side of the upper inner surface of the telescopic tube 12, and a fixed plate 13 is symmetrically fixedly connected to the other side of the upper inner surface of the telescopic tube 12. The two fixed plates 13 are connected to a rotating shaft 14 for rotation together, and the end of the spring 11 away from the inner surface of the telescopic tube 12 is fixedly connected to the lower part of the pruning knife 3.

[0028] Specifically, when the device in this solution has not started to prune branches, the spring 11 is in a stretched state, and at the same time, the spring 11 pulls the lower part of the pruning knife 3, so that the pruning knife 3 as a whole is in a nearly horizontal position. Before pruning begins, when the fixed half ring 42 is used to fix the branches, the pruning knife 3 will not affect the fixation of the fixed half ring 42 to the branches.

[0029] See Figure 3 The fixing mechanism 4 includes two semicircular plates 41 fixedly connected to the top of the telescopic tube 12. A fixed semi-ring 42 is fixedly connected to the side of the semicircular plate 41 away from the pruning knife 3. The two semicircular plates 41 are fixedly connected to a fixed shaft 43.

[0030] Furthermore, when using the device for pruning, the two fixed half rings 42 are first used to fix the branches to be pruned to ensure that they will not shift during the shearing process, thereby increasing the difficulty of pruning. At the same time, pruning with fixed branches can improve the efficiency of pruning.

[0031] See Figure 2 and Figure 3 The lower part of the trimming knife 3 is rotatably connected to the outer surface of the fixed shaft 43, and the trimming part of the trimming knife 3 is opposite to the inner surface of the fixed half ring 42.

[0032] Furthermore, when the inner surface of the fixed half ring 42 is in close contact with the branch to be pruned, the traction ring 51 is pulled to drive the lower part of the pruning knife 3 so that the pruning knife 3 rotates around the fixed axis 43. At this time, the pruning knife 3 begins to cut the branch fixed by the fixed half ring 42, and the blade part of the pruning knife 3 is located between the two fixed half rings 42.

[0033] During the pruning process, when the lower part of the pruning knife 3 rotates to the inner surface of the telescopic tube 12, the blade part of the upper part of the pruning knife 3 just moves to the top of the telescopic tube 12, and the spring 11 is stretched to the maximum. When the cutting is completed, the traction ring 51 is no longer pulled. At this time, the stretched spring 11 returns to its original state, driving the lower part of the pruning knife 3 to move, so that the pruning knife 3 as a whole returns to its initial state.

[0034] See Figure 5 The gripping mechanism 2 includes a fixed rod 24 fixedly connected to the bottom end of the traction ring 51, and both ends of the fixed rod 24 are rotatably connected to T-shaped handles 23.

[0035] See Figure 5 The lower part of the outer surface of the telescopic tube 12 is fixedly connected to a fixing ring 21, and the outer surface of the fixing ring 21 is fixedly connected to a handle 22 on one side close to the traction rope 52. The horizontal part of the T-shaped handle 23 is rotatably connected to the handle 22 at one end away from the fixing rod 24.

[0036] Specifically, when the branch is fixed by the fixing half ring 42 and needs to be cut, the T-shaped handle 23 is squeezed in the direction close to the handle 1 22. At this time, the horizontal part of the T-shaped handle 23 moves downward away from the end of the handle 1 22, thereby driving the fixing rod 24 to move downward. Since the fixing rod 24 is fixedly connected to the traction rope 52, it will drive the traction rope 52 to move downward, thereby driving the traction ring 51 at the upper end of the traction rope 52 downward and the lower part of the pruning knife 3 to rotate.

[0037] See Figure 4 The traction mechanism 5 includes a traction ring 51 fixedly connected to the lower portion of the pruning knife 3, and a traction rope 52 is fixedly connected to the bottom end of the traction ring 51. The upper and middle outer surfaces of the traction rope 52 are in close contact with the outer surface of the rotating shaft 14.

[0038] When the traction rope 52 is driven downward, the outer surface of the traction rope 52 moves downward along the outer surface of the rotating shaft 14. At the same time, the two fixing plates 13 cooperate with the rotating shaft 14 to form a limiting groove to prevent the position of the traction rope 52 from shifting during the movement, thereby causing the lower part of the pruning knife 3 to be unable to rotate. At the same time, after the cutting is completed, the pruning knife 3 returns to its original position, driving the traction rope 52 to move upward, and cooperating with the fixing plates 13 and the rotating shaft 14 to prevent the position of the traction rope 52 from shifting.

[0039] The working principle of this utility model is:

[0040] First, before pruning, use the semicircular plate 41 and the fixing half ring 42 to fix the branch to be pruned, and at the same time pinch the T-shaped handle 23 and the lower part of handle 1 22 to make the lower part of the T-shaped handle 23 move closer to handle 1 22, which will then drive the fixing rod 24 and the traction rope 52 to move downward, thereby making the traction ring 51 downward.

[0041] At the same time, the fixed shaft 43 and the traction ring 51 move downward, so that the lower part of the pruning knife 3 rotates to the side away from the spring 11, thereby driving the upper part of the pruning knife 3 to rotate, and the spring 11 is stretched by the pruning knife 3.

[0042] Continue to squeeze the T-shaped handle 23 until the pruning knife 3 finishes cutting the branch, then release the T-shaped handle 23. At this time, the fixing rod 24 and the traction rope 52 are no longer subjected to the downward force. At the same time, the spring 11 returns to its original shape, driving the lower part of the pruning knife 3 to rotate in the direction close to the spring 11, so that the pruning knife 3 also returns to its original shape and continues the next pruning.
