DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1-2 As shown, a municipal greening plant high branch pruning device includes a grip rod 1, the upper end of the grip rod 1 is fixedly connected to a motor 2, an extension component 3 is fixedly installed on the front of the motor 2 through a coupling, a clamping component 4 is slidably installed on the outer surface of the extension component 3, and the extension component 3 is limited and fixed by the set clamping component 4, a telescopic component 5 is fixedly installed on the upper end of the motor 2, and the overall height of the device can be adjusted by the set extension component 3 and the telescopic component 5, and a cutting component 6 is fixedly installed on the upper part of the telescopic component 5, and the cutting component 6 can be used to cut high branches when it is rotated during use.

[0026] In order to adjust the height of the device according to the different positions of the high branches, refer to Figure 1-4 The telescopic assembly 5 includes a main rod 51 fixedly connected to the upper end of the motor 2, a secondary rod 52 is slidably connected to the inner surface of the main rod 51, a plurality of positioning holes 53 are provided in a linear array on the left part of the outer surface of the main rod 51, a mounting groove 54 is provided on the left part of the outer surface of the secondary rod 52, a spring 55 is fixedly connected to the left side wall of the inner surface of the mounting groove 54, and a buckle 56 is fixedly connected to the right end of the spring 55.

[0027] Furthermore, the outer diameter of the buckle 56 is smaller than the inner diameter of the plurality of locking holes 53 .

[0028] By pressing the buckle 56 toward the inner cavity of the installation groove 54, the buckle 56 squeezes the spring 55, and then the buckle 56 shrinks into the inner cavity of the installation groove 54. Then the person can pull the sub-rod 52 upward, and when the buckle 56 moves upward, when it passes through the locking hole 53, it can be seen from the above that the outer diameter of the buckle 56 is smaller than the inner diameter of some locking holes 53. Therefore, the buckle 56 can be popped outward under the action of the spring 55, and then locked in the inner cavity of the locking hole 53. If the length needs to be further adjusted, just continue to repeat the above operation. When the telescopic component 5 extends upward, the overall length of the extension component 3 also extends upward.

[0029] In order to achieve the purpose of fixing the entire length of the extension component 3 after extension, refer to Figure 1-4 The extension component 3 includes a turntable 31 fixedly connected to the front of the motor 2 through a coupling, a first telescopic plate 32 is fixedly connected to the lower middle part of the front end of the turntable 31, a second telescopic plate 33 is slidably connected to the inner surface of the first telescopic plate 32, and a plurality of mutually matching limiting holes 34 are linearly arrayed at the front ends of the first telescopic plate 32 and the second telescopic plate 33.

[0030] Furthermore, the clamping assembly 4 includes a slider 41 slidably connected to the outer surface of the first telescopic plate 32, a threaded groove 42 is provided at the front end of the slider 41, a threaded rod 43 is threadedly connected to the inner surface of the threaded groove 42, and a hexagonal block 44 is fixedly connected to the front end of the threaded rod 43, thereby improving the fixing effect after the device is extended.

[0031] Furthermore, the number of the plurality of limiting holes 34 is equal to the number of the plurality of locking holes 53 .

[0032] When the extension component 3 is extended upward by the telescopic component 5, the second telescopic plate 33 slides upward in the inner cavity of the first telescopic plate 32, and the plurality of limiting holes 34 and the plurality of locking holes 53 provided on the outer surface of the second telescopic plate 33 are parallel to each other, and the number of the plurality of limiting holes 34 and the plurality of locking holes 53 are equal, so the telescopic component 5 drives the extension component 3 to move upward by an equal distance, and then the personnel slides upward the slider 41 slidably connected to the outer surface of the first telescopic plate 32, so that the slider 41 drives the internal components thereof to move upward at the same time, and then when it moves to the limiting hole 34 aligned with the position of the buckle 56, the personnel only needs to rotate the hexagonal block 44 so that the hexagonal block 44 drives the threaded rod 43 to gradually approach inward in the thread groove 42, and then the threaded rod 43 is inserted into the overlapping limiting holes 34 between the first telescopic plate 32 and the second telescopic plate 33, thereby achieving the fixing effect of the extension component 3.

[0033] After the extension assembly 3 and the telescopic assembly 5 are fixed, the motor 2 can be driven to drive the extension assembly 3 to rotate the cutting assembly 6 for cutting.

[0034] In order to achieve the purpose of the extension assembly 3 driving the cutting assembly 6 to cut, refer to Figure 1-3 The cutting assembly 6 includes a fixed platform 61 fixedly connected to the upper end of the auxiliary rod 52, and a transmission plate 62 is rotatably connected to the middle part of the front side of the outer surface of the fixed platform 61 through a transmission rod, and a hacksaw 63 is fixedly connected to the upper part of the outer surface of the transmission plate 62.

[0035] Furthermore, the upper portion of the rear end of the second telescopic plate 33 is fixedly connected to the lower side of the middle portion of the rear end of the transmission plate 62 .

[0036] By starting the motor 2, the output end of the motor 2 drives the turntable 31 fixedly connected thereto to rotate through the coupling. When the turntable 31 rotates, since the first telescopic plate 32 is fixedly connected to the lower middle side of the front end of the turntable 31, and the upper rear end of the second telescopic plate 33 is fixedly connected to the lower middle side of the rear end of the transmission plate 62, when the turntable 31 rotates, the first telescopic plate 32 and the second telescopic plate 33 can be driven to rotate eccentrically at the same time, so that the second telescopic plate 33 drives the transmission plate 62 to rotate in the middle of the front side of the outer surface of the fixed platform 61 under the action of the transmission rod. Therefore, the transmission plate 62 can drive the hacksaw 63 fixed on its outer surface to rotate, and then the personnel can hold the handle 1 to extend the device to the position of the high branch, so that the hacksaw 63 cuts the high branch, avoiding manual climbing to the high branch to cut, thereby reducing labor.

[0037] It should be noted that the specific installation method of the motor 2, the circuit connection method and the control method used in the present invention are all conventional designs, and the present invention will not elaborate on them in detail.

[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments.
