[0002] During the planting process of fruit trees, the branches need to be pruned and the branch distribution of the fruit trees needs to be combed. The advantages of pruning the branches are as follows: adjusting the tree vigor, allowing the branches to grow disorderly, the framework being not firm, when there are more fruits, the branches will bend and droop, even split, causing the tree to be damaged and affecting the service life of the tree; concentrating nutrients, the fruit trees generally have strong branch growth, not only the dormant buds can germinate into branches, but also some annual new shoots can sprout branches multiple times, if they are allowed to grow naturally, not only the nutrients are consumed, but also the tree crown is easy to be closed, affecting ventilation and light transmission, and being not conducive to flower bud formation and flowering and fruiting; solving the tree closure, due to different tree species, varieties and tree ages, the fruiting habits are also different, such as apples, mainly short fruit branch fruiting, but during the young tree period, long fruit branch fruiting is dominant, and after the tree age increases, it gradually changes into short fruit branch fruiting.

[0003] In the prior art, there is an electric trimmer, which can greatly improve the working efficiency of branch pruning and reduce the labor intensity of pruning personnel, but when pruning branches located at a high place, auxiliary tools such as ladders are still needed, or the main trunk needs to be climbed, which reduces the overall pruning efficiency, so a handheld combing device for fruit trees needs to be designed.

[0023] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0024] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0025] like Figures 1-3 As shown, a handheld fruit tree trimming device includes: a telescopic rod 1, a mounting base 2 assembled at one end of the telescopic rod 1, an electric pruner 3 detachably mounted on the mounting base 2 via a mounting mechanism, a guide 4 assembled on the mounting base 2, a switch control unit assembled on the mounting base 2 and matched with the start switch of the electric pruner 3, and a pull rope 5 connected to the switch control unit for driving the switch control unit to press the start switch of the electric pruner 3.

[0026] The electric trimmer 3 includes a fixed shear and a rotatable movable shear, and the guide 4 includes a pair of guide arms 6 corresponding to the fixed shear and the movable shear respectively in the deployed state.

[0027] The branches need to be pruned and trimmed. The electric trimmer 3 is mounted on the mounting base 2 through the mounting mechanism. The telescopic rod 1 is extended, and the two guide arms 6 on the guide 4 are moved to both sides of the branch to be pruned. The telescopic rod 1 is pushed, and under the action of the pair of guide arms 6, the branch will move between the fixed shear and the movable shear. Then the pull rope 5 is pulled, which will cause the switch control unit to press against the start switch of the electric trimmer 3. The movable shear will approach the fixed shear and rotate to cut the branch.

[0028] A pair of guide arms 6 facilitates the movement of the movable and fixed shears to both sides of the branch. The guide arms 6 also help the electric trimmer 3 to be positioned, enabling the trimming of high branches even when there are leaves obstructing the view or when it is inconvenient to observe. This makes it highly practical.

[0029] Both the telescopic pole 1 and the electric trimmer 3 are existing mature technologies, so their specific structures and working principles will not be described in this article.

[0030] The switch control unit comprises a mounting plate 7 fixedly connected with the mounting base 2 through the connecting frame, a bent arm 8 hingedly connected with the mounting plate 7 at a bending position through a hinge shaft, a limiting piece assembled on the mounting plate 7 and capable of abutting against the bent arm 8, and an elastic piece 9 for pushing the bent arm 8 to rotate away from the electric trimmer 3;

[0031] One end of the bent arm 8 corresponds to the start switch of the electric trimmer 3, and the other end of the bent arm 8 is connected with the pull cord 5.

[0032] When the pull cord 5 is pulled, the pull cord 5 drives the bent arm 8 to rotate around the hinge shaft, and the end of the bent arm 8 away from the pull cord 5 will press on the start switch of the electric trimmer 3, so as to start the electric trimmer 3; after the pull cord 5 is released, the elastic piece 9 will push the bent arm 8 to return to the original position and abut against the limiting piece.

[0033] The elastic piece 9 is a metal spring piece assembled on the mounting plate 7 through a plurality of first mounting bolts and abutting against one end of the bent arm 8.

[0034] The end of the pull cord 5 away from the bent arm 8 is connected with a pull ring 10.

[0035] At least one cord guide ring 11 for the pull cord 5 to pass through is assembled on the mounting plate 7 and the telescopic rod 1.

[0036] The mounting mechanism comprises a support frame 12 fixedly connected with the mounting base 2 and a limiting frame 14 detachably assembled on the support frame 12 through a plurality of second mounting bolts 13, and the support frame 12 and the limiting frame 14 are both provided with an arc-shaped portion abutting against the handle of the electric trimmer 3.

[0037] The limiting frame 14 is detached by unscrewing the second mounting bolts 13, so that the electric trimmer 3 can be detached for charging; when the electric trimmer 3 is mounted, the handle of the electric trimmer 3 is placed on the arc-shaped portion of the support frame 12, and then the arc-shaped portion of the limiting frame 14 is abutted against the handle of the electric trimmer 3, and the limiting frame 14 is fixed with the support frame 12 through the second mounting bolts 13.

[0038] The preferred embodiments of the present application are described in detail above with reference to the drawings, but the present application is not limited to the specific details in the above-described embodiments, and various simple modifications can be made to the technical solutions of the present application within the technical concept of the present application, and these simple modifications all belong to the protection scope of the present application.

[0039] In addition, it should be noted that each specific technical feature described in the above specific embodiments can be combined in any appropriate manner without contradiction, and in order to avoid unnecessary repetition, the present application will not describe various possible combinations again.

[0040] Furthermore, various different embodiments of the present application can be combined with each other as long as they do not violate the spirit of the present application, and should be considered as disclosed in the present application.
