[0002] Macadamia trees are tropical nut trees, evergreen trees with a height between 10 and 15 meters, having a broad crown and growing relatively fast. Pruning their branches and leaves is crucial for the health of the trees and the fruit yield. Regular pruning can remove over-dense branches and leaves, increase light and air circulation, reduce the humidity inside the crown, and thus reduce the probability of disease occurrence.
[0003] Due to the height of macadamia trees and the breadth of their crowns, pruning work is somewhat difficult, especially for the parts at high places and those that are difficult to reach.

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0030] Refer to Figure 1 - Figure 2 As an embodiment provided by the present utility model: A branch and leaf pruning device for macadamia trees includes a long rod 1. The long rod 1 is used to support the entire device and allows the operator to prune the branches and leaves at high positions on the ground. The end of the long rod 1 is fixedly connected with a mounting seat 2, and the end of the mounting seat 2 is fixedly connected with a fixed blade 3. The mounting seat 2 provides a stable fixing effect for the fixed blade 3. The fixed blade 3 is used for actual cutting of the branches and leaves and jointly completes the pruning work with the movable blade 4. The movable blade 4 is hinged on the surface of the fixed blade 3 and rotates around the hinge point with the fixed blade 3 to adapt to branches and leaves of different thicknesses and achieve more precise pruning.
[0031] Refer to Figure 2 - Figure 3, a linkage component 5 is provided on the surface of the long rod 1. The linkage component 5 is used to operate the height-adjustable blade 4 at a low position. The linkage component 5 includes a movable sleeve 51. The movable sleeve 51 is sleeved on the outer wall of the long rod 1. A support rod 52 is hinged on the surface of the movable sleeve 51. The end of the support rod 52 is hinged to the end of the movable blade 4. The support rod 52 is used to connect the movable sleeve 51 and the end of the movable blade 4 together, so that the movement of the movable sleeve 51 drives the movable blade 4 to move. A fixed sleeve 53 is fixedly connected to the outer wall of the long rod 1. The fixed sleeve 53 and the movable sleeve 51 are elastically connected by a return spring 54. The fixed sleeve 53 is used to support the bottom end of the return spring 54. Thus, through the elastic support of the return spring 54, the movable sleeve 51 moves upward and is transmitted to the movable blade 4 through the support rod 52, causing the movable blade 4 to automatically open.
[0032] Refer to Figure 2 - Figure 3 , a plurality of groups of chutes 55 distributed in an array are formed on the outer wall of the long rod 1. A slider 56 is slidably connected inside the chute 55. One end of the slider 56 is fixedly connected to the inner wall of the movable sleeve 51. The other end of the slider 56 is fixedly connected to a pull rod 57. The chute 55 communicates the inside and the outside of the long rod 1. The movable sleeve 51 and the pull rod 57 are connected together through the slider 56. By pulling the pull rod 57, the movable sleeve 51 is controlled to move downward, so that the return spring 54 is compressed, and the movable blade 4 approaches the fixed blade 3 to complete the cutting of branches and leaves. A communication groove 58 is formed on the outer wall of the long rod 1. A handle 59 is slidably connected inside the communication groove 58. The handle 59 is fixedly connected to the outer wall of the pull rod 57. The communication groove 58 is used to provide a movement space for the handle 59, and it is convenient for the operator to pull the pull rod 57 downward through the handle 59.
[0033] Refer to Figure 1 、 Figure 4 , a protective component 6 is provided on the outer wall of the fixed sleeve 53. The protective component 6 includes brackets 61. A plurality of groups of brackets 61 are arranged in an array, and all the plurality of groups of brackets 61 are fixedly connected to the outer wall of the fixed sleeve 53. A transparent cloth 62 is fixedly connected to the surface of the brackets 61. The plurality of groups of brackets 61 are used to support and fix the transparent cloth 62. The transparent cloth 62 protects the operator from the splashing of branches and leaves and the fragments generated during cutting during the pruning process, and the transparent cloth 62 allows the operator to still clearly observe the working area and accurately prune the branches and leaves. A reinforcing rod 63 is fixedly connected to the bottom surface of the bracket 61. The bottom end of the reinforcing rod 63 is fixedly connected to the outer wall of the long rod 1. The reinforcing rod 63 is used to reinforce the bracket 61 to ensure the firmness and stability of the bracket 61.
[0034] Working principle: The operator holds the handle 59 on the ground. By pulling the pull rod 57, the movable sleeve 51 moves downward along the chute 55. At this time, the return spring 54 is compressed, and the movable blade 4 approaches the fixed blade 3. The operator precisely places the branches and leaves between the two blades by observing the area covered by the transparent cloth 62. After the branches and leaves are clamped, the operator continues to pull the pull rod 57, causing the movable blade 4 to come into close contact with the fixed blade 3 to complete the cutting action. After the cutting is completed, the operator releases the pull rod 57, and the elastic force of the return spring 54 causes the movable sleeve 51 to move upward, and the movable blade 4 opens accordingly, preparing for the next cutting. The transparent cloth 62 is supported by the bracket 61 to maintain a good view, ensuring that the operator can continuously observe and precisely perform the pruning work.
[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
