[0003] Common restoration techniques for forestry restoration include:

[0004] Afforestation techniques: including direct seeding afforestation, seedling afforestation, and vegetative propagation afforestation, direct seeding afforestation is to sow seeds directly on afforestation land, seedling afforestation is to plant seedlings, and vegetative propagation afforestation is to use tree vegetative organs for afforestation;

[0005] Forest tending techniques: through light transmission tending, growth tending, and other measures, adjust stand structure, remove poorly growing and overly dense trees, promote the growth of retained trees, and improve forest quality;

[0006] Soil improvement techniques: for damaged forest soil, measures such as applying organic fertilizer and biochar can be taken to increase soil fertility and improve soil structure, providing good soil conditions for tree growth.

[0007] Among them, during the process of afforestation, in order to balance tree vigor, improve ventilation and light transmission, and reduce pests and diseases, regular pruning of trees is required. There are many types of existing tree pruning devices, one of which is an electric high branch saw. By setting an electric chain saw at the top of the telescopic rod, efficient pruning of branches can be achieved.

[0008] However, in actual operation, due to the setting of the electric chain saw and the corresponding battery, the overall weight of the electric high branch saw is relatively heavy, and long-term handheld operation will cause great arm fatigue to the workers. Therefore, in order to further reduce the work intensity of the workers in pruning branches, a tree pruning device for forestry planting is provided. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0025] Please refer to Figs. 1-3 In the embodiments of the utility model, a tree pruning device for forestry planting comprises a high branch saw assembly 1 composed of an adjustable telescopic rod 101, an electric chain saw 102 and a battery pack 103. The electric chain saw 102 and the battery pack 103 are respectively installed at the upper and lower ends of the adjustable telescopic rod 101. An auxiliary support assembly 2 is arranged outside the sleeve at the bottom of the adjustable telescopic rod 101. The auxiliary support assembly 2 is used for achieving auxiliary support for the high branch saw assembly 1.

[0026] The auxiliary support assembly 2 comprises a storage straight groove 201, a support column 202 and a rotating handle 203.

[0027] The storage straight groove 201 is fixed to the bottom of the sleeve at the bottom of the adjustable telescopic rod 101. The support column 202 is stored inside the storage straight groove 201. The rotating handle 203 is fixed to the bottom of the support column 202 and penetrates through the two sides of the storage straight groove 201. The rotating handle 203 is rotationally connected with the storage straight groove 201.

[0028] The support column 202 is turned out from the inside of the storage straight groove 201 and supports the ground to achieve auxiliary support for the high branch saw assembly 1.

[0029] An external thread 204 is formed on the side wall of the storage straight groove 201 close to the rotating handle 203. A locking nut 205 is threadedly connected with the rotating handle 203 through the external thread 204. The locking nut 205 is tightly attached to the wall of the storage straight groove 201 to achieve position locking of the rotating handle 203.

[0030] A fixed handle 104 is fixed to the wall of the sleeve at the bottom of the adjustable telescopic rod 101. The fixed handle 104 is located above the rotating area of the rotating handle 203.

[0031] In the embodiment, it needs to be pointed out that the high branch saw assembly 1 is a common electric high branch saw in the market, and its operating principle is the same. The adjusting structure of the adjustable telescopic rod 101, the electrical connection structure of the electric chain saw 102 and the battery pack 103 are all conventional structures of the electric high branch saw, so the detailed structure of the high branch saw assembly 1 will not be described here.

[0032] In daily use, the support column 202 is stored in the storage straight groove 201, and the rotating handle 203 is distributed in parallel with the adjustable telescopic rod 101. At this time, the user holds one hand on the fixed handle 104 and the other hand on the tail of the bottom sleeve of the adjustable telescopic rod 101 or the rotating handle 203. The operation method is the same as that of the traditional electric high branch saw.

[0033] In addition, the support column 202 can also be turned out of the storage straight groove 201. By loosening the locking nut 205, it is not in contact with the outer wall of the storage straight groove 201, and then the locking of the rotating handle 203 is released. After that, the rotating handle 203 and the support column 202 can be rotated as a whole, and the end of the support column 202 away from the rotating handle 203 contacts the ground, thereby providing auxiliary support for the high branch saw assembly 1. The high branch saw assembly 1 can be vertically rotated around the rotating point of the storage straight groove 201 and the rotating handle 203, and the high branch saw assembly 1 can also be horizontally rotated around the support column 202. In this way, the orientation of the high branch saw assembly 1 can be conveniently adjusted, and the sawing operation of the branches can be completed. During this process, compared with the traditional operation method of lifting the high branch saw assembly 1 with both hands, the support column 202 supports the high branch saw assembly 1, which makes the operation more labor-saving and further reduces the working intensity during branch pruning.

[0034] Please refer to Figs. 1-3 , when the support column 202 is stored in the storage straight groove 201, the rotating handle 203 is distributed outside the battery pack 103, and the rotating area of the rotating handle 203 is larger than the outer wall size of the battery pack 103.

[0035] The end of the rotating handle 203 away from the support column 202 is formed with an opening structure, and the width of the opening structure is greater than the outer diameter of the sleeve at the bottom of the adjustable telescopic rod 101 and the width of the outer wall of the storage straight groove 201.

[0036] In the embodiment, the structure can prevent the rotating handle 203 from interfering with the battery pack 103 and the adjustable telescopic rod 101 when rotating, and can realize large-angle vertical rotation adjustment of the adjustable telescopic rod 101.

[0037] The above merely describes a preferred embodiment of the present application, and the protection scope of the present application is not limited thereto, and any skilled person in the art, according to the technical scheme and the inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
