[0021] Now, the present utility model will be further described in detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.

[0022] Please refer to Figures 1-6, A pruning device for trees on both sides of a road, including a pruning motor 1 and a cutting saw blade 2 on the pruning motor 1. The pruning motor 1 is swingably arranged in an installation frame 3. When the pruning motor 1 swings up and down, the cutting saw blade 2 swings accordingly, facilitating the adjustment of the cutting angle. A operating handle 5 is provided below the installation frame 3. A first storage battery 501 for driving the pruning motor 1 is arranged in the operating handle 5. The installation frame 3 is detachably fixed to a connection structure 6 through the operating handle 5. An infinitely variable telescopic rod 7 is provided below the connection structure 6. The infinitely variable telescopic rod 7 drives the installation frame 3 and the (pruning motor 1) cutting saw blade 2 to rise or fall, thereby achieving cutting at different heights. Therefore, this device can adjust the pruning angle of trees and can also adjust the height, with a large application range and strong practicability.

[0023] In the solution of the present utility model, the installation frame 3 is U-shaped. Rotating gears 401 are provided on both sides of the installation frame 3. The rotating gears 401 pass through the installation frame 3 and are fixed to the pruning motor 1. A bidirectional driving motor 402 is arranged in the installation frame 3. Adjusting gears 4 are respectively provided on two output ends of the bidirectional driving motor 402. The adjusting gears 4 are meshed with the rotating gears 401. After the bidirectional driving motor 402 operates, the pruning motor 1 is driven to swing up and down through the adjusting gears 4 and the rotating gears 401. During use, if it is necessary to adjust the cutting angle of the cutting saw blade, only need to drive the bidirectional driving motor 402. After the bidirectional driving motor 402 operates, the adjusting gears 4 at both ends operate, thereby driving the rotating gears 401 to rotate. Since the rotating gears 401 are fixedly connected to the pruning motor 1, when the rotating gears 401 rotate, the pruning motor 1 is driven to swing up and down, thus meeting the requirement of cutting angle adjustment.

[0024] Further, the connection structure 6 includes an I-shaped mounting plate 601. Two sets of clamping mechanisms are provided on one side of the I-shaped mounting plate 601. The clamping mechanism includes two oppositely arranged mirror image clamping plates 603. The distance between the two mirror image clamping plates 603 is adjusted by a threaded rod 602. The operating handle 5 is fixed to the I-shaped mounting plate 601 through the mirror image clamping plates 603.

[0025] Please refer to again Figure 5 , as shown in the figure, four mirror image clamping plates 603 are provided on one side of the I-shaped mounting plate 601. The four mirror image clamping plates are arranged in pairs oppositely, and each mirror image clamping plate 603 is connected to the groove of the I-shaped mounting plate 601 through a threaded rod 602. Therefore, the relative two threaded rods 602 can control the distance between the two mirror image clamping plates 603. When the two mirror image clamping plates 603 gradually approach, the operating handle 5 can be fixed to the I-shaped mounting plate 601.

[0026] Since the operating handle 5 is detachably connected to the I-shaped mounting plate 601, the device can also be operated by hand without the stepless telescopic rod and is applicable to pruning trees with relatively low heights.

[0027] Specifically, the stepless telescopic rod 7 includes an extended mounting tube 701, a connecting telescopic tube 702, and a basic operating tube 703. The extended mounting tube 701 can telescopically move within the connecting telescopic tube 702, and the connecting telescopic tube 702 can telescopically move within the basic operating tube 703. The heights of the mounting frame 3 and the cutting saw blade 2 are adjusted by the extended mounting tube 701, the connecting telescopic tube 702, and the basic operating tube 703.

[0028] The extended mounting tube 701 is fixed to the bottom of the I-shaped mounting plate 601. The connecting telescopic tube 702 is slidably clamped to the outside of the extended mounting tube 701. The basic operating tube 703 is sleeved on the outside of the connecting telescopic tube 702. An extended electric screw rod 704 is inlaid and installed inside the extended mounting tube 701. The extended electric screw rod 704 is threadedly connected to the connecting telescopic tube 702. A telescopic electric threaded tube 705 is fixedly installed at the lower end of the basic operating tube 703. The telescopic electric threaded tube 705 is threadedly connected to the lower end of the connecting telescopic tube 702. The telescopic electric threaded tube 705 is slidably clamped to the extended electric screw rod 704.

[0029] In this embodiment, both the extended electric screw rod 704 and the telescopic electric threaded tube 705 are operated by motors. One motor is arranged at the top of the extended electric screw rod 704, and the other is arranged at the bottom of the telescopic electric threaded tube 705. After the extended electric screw rod 704 rotates, the extended mounting tube 701 extends out of the connecting telescopic tube 702. After the telescopic electric threaded tube 705 operates, the connecting telescopic tube 702 extends out of the basic operating tube 703. Such telescoping can achieve height adjustment.

[0030] A regulating handle 8 is arranged at the bottom of the stepless telescopic rod 7. A second storage battery 9 for controlling the extended electric screw rod 704 and the telescopic electric threaded tube 705 is arranged inside the regulating handle 8.

[0031] Obviously, the above embodiments are merely examples given for clear illustration and are not limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. The obvious changes or modifications derived therefrom still fall within the protection scope of the present invention.
