[0061] The power assembly 36 is fixed to the bottom of the mobile bracket 33, and the power assembly 36 is linked with the rotating assembly 32 to form a transmission pair for driving the rotating assembly 32 to rotate, wherein the power assembly 36 includes a sawtooth disk 365 for cutting tree branches.

[0062] In the utility model, the cutting part 3 is powered by the energy unit 4 to complete the cutting process, and an appropriate number of connecting rod assemblies 21 can be selected for splicing according to the actual height of the tree pole to meet the cutting height requirements. The glove 22 is installed at the bottom of the connecting rod assembly 21 located at the bottom, which is convenient for gripping and avoids damage to the hand. The lower end of the threaded connection column 31 is connected to the top of the connecting rod assembly 21 located at the top, that is, the cutting part 3 and the adjusting part 2 are installed together from top to bottom.

[0063] In the present invention, the power assembly 36 is linked with the rotating assembly 32 to form a transmission pair that drives the rotating assembly 32 to rotate, that is, the power assembly 36 can simultaneously drive the rotating assembly 32 to rotate while driving the sawtooth disk 365 to rotate; the rotating assembly 32 can further drive the moving bracket 33 (together with the power assembly 36) to move upward during the rotation process. The moving bracket 33 and the moving clamping plate 37 are both slidably connected to the guide rod 35, so that the moving bracket 33 and the moving clamping plate 37 can move in the vertical direction. The guide rod 35 does not contact the rotating assembly 32, so as to avoid the guide rod 35 being stuck in the rotating assembly 32.

[0064] In the present invention, the power assembly 36 is linked with the rotating assembly 32 to form a transmission pair, so that the sawtooth disk 365 and the rotating assembly 32 rotate simultaneously (at different speeds).

[0065] In the present invention, when the rotating assembly 32 rotates and drives the movable bracket 33 to move upward, the cutting process is as follows:

[0066] S1: The movable bracket 33 moves upward, and the movable clamping plate 37 moves upward accordingly, until the tree pole is clamped between the movable clamping plate 37 and the fixed clamping plate 34;

[0068] S3: The sawtooth disk 365 moves upward until the tree pole is completely cut off, the power is turned off, and the rotating assembly 32 and the sawtooth disk 365 stop working.

[0069] S4: Manually control the rotating assembly 32 to rotate in the opposite direction, so that the movable bracket 33 moves downward to facilitate the removal of the tree pole, and the movable bracket 33 and the movable clamping plate 37 move downward to the initial position.

[0070] In the utility model, the cutting process can simultaneously achieve the following effects:

[0071] 1. The sawtooth disc 365 moves upward continuously (and slowly) to complete the cutting of tree branches;

[0072] 2. The movable bracket 33 assembly moves upward to compress the spring so that the tree pole is clamped between the movable clamping plate 37 and the fixed clamping plate 34.

[0073] It should be noted that the diameter of the through hole 33 c is 1-2 mm larger than the diameter of the threaded connection column 31 to ensure that the movable bracket 33 does not cause wear to the circumference of the threaded connection column 31 when moving in the vertical direction, thereby improving the service life of the threaded connection column 31.

[0074] The connecting rod assembly 21 includes a support rod 211, a connector 213 is disposed on the top of the support rod 211, and the connector 213 is in a cylindrical shape with an opening upward and a thread is disposed on the inner wall thereof;

[0075] The lower part of the support rod 211 is provided with a first thread 212 , and the circumferential surface of the lower part of the threaded connection column 31 is provided with a second thread 31 a . The lower part of the support rod 211 or the threaded connection column 31 is screwed into the connector 213 .

[0076] In the present invention, the parameters of the thread 1 212 and the thread 2 31a are the same, so they can both be screwed into the connector 213; the plurality of support rods 211 are threadedly connected in sequence, which is convenient for disassembly and installation and more convenient to use.

[0077] The rotating assembly 32 includes a rotating disk 321, a sleeve 323 and a supporting plate 324;

[0078] A thread three 31b is arranged on the circumference of the middle part of the threaded connection column 31, and a threaded hole is arranged correspondingly in the middle part of the turntable one 321, and the threaded connection column 31 is threadedly rotatably connected with the turntable one 321;

[0079] The sleeve 323 and the support plate 324 have through holes in the middle for the threaded connection column 31 to pass through;

[0080] The turntable 1 321 is fixed to the bottom of the sleeve 323 , the support plate 324 is fixed to the top of the sleeve 323 , and the movable bracket 33 presses the support plate 324 .

[0081] In the present invention, the threaded connection column 31 is threadedly connected to the turntable 1 321, which prevents the turntable 1 321 from sliding under the action of axial force (or gravity), ensures the stability of the device during use, ensures the clamping effect on the tree pole, and prevents the tree pole from falling and injuring people. The mobile bracket 33 presses the support plate 324, and the support plate 324 can stably drive the mobile bracket 33 to move upward.

[0082] At least two guide rods 35 are provided;

[0083] The movable bracket 33 is provided with a guide hole 33a for the guide rod 35 to pass through;

[0084] The movable clamping plate 37 is provided with a through hole for the guide rod 35 to pass through.

[0085] In the present invention, the two guide rods 35 can increase the stability of the movable bracket 33 when it moves, and ensure that the movable bracket 33 will not tilt when it moves in the vertical direction.

[0086] The power assembly 36 also includes a motor 361, a rotating shaft 362, a second rotating disk 363 and a baffle 366;

[0087] The motor 361 is fixed to the bottom of the mobile bracket 33, and the output end of the motor 361 is connected to the rotating shaft 362 through a coupling;

[0088] The second rotating disk 363 and the sawtooth disk 365 are key-connected and arranged on the rotating shaft 362, and the second rotating disk 363 is located between the motor 361 and the sawtooth disk 365;

[0089] A plurality of active rods 364 are arranged on the circumference of the second rotating disk 363, and a plurality of driven rods 322 are arranged on the circumference of the first rotating disk 321. The active rods 364 abut against the driven rods 322 to form a rotation linkage mechanism in the vertical direction.

[0090] Wherein, the number of active rods 364 is less than the number of driven rods 322;

[0091] The baffle 366 is disposed at the end of the rotating shaft 362 .

[0092] In the present invention, the motor 361 drives the second turntable 363 to rotate, and the second turntable 363 drives the driven rod 322 (and the first turntable 321) to rotate through the active rod 364, thereby realizing the linkage effect of the second turntable 363 and the first turntable 321;

[0093] The number of active rods 364 is less than the number of driven rods 322 , so that when the second turntable 363 rotates multiple times, the first turntable 321 rotates only one circle.

[0094] During operation, the sawtooth disk 365 rotates multiple times to ensure the cutting effect on the tree pole, while the turntable 321 rotates only one circle, which slows down the upward movement distance of the turntable 321 (and the sawtooth disk 365) to improve the cutting effect of the sawtooth disk 365 to the best; avoid the sawtooth disk 365 from getting stuck or breaking due to the sawtooth disk 365 rising too fast, and ensure good cutting quality and safe cutting process.

[0095] It should be noted that the baffle 366 is circular, and its diameter is smaller than the diameter of the serrated disk 365 , so as to prevent the baffle 366 from interfering with the serrated disk 365 .

[0096] It should be noted that when the spring 38 is in the naturally extended state (initial state of cutting), the horizontal height of the top of the serrated disk 365 is flush with the horizontal height of the upper surface of the movable clamping plate 37, or is 5-10 mm higher than the upper surface of the movable clamping plate 37, so as to ensure the best cutting effect on the tree branch and avoid the phenomenon of incomplete cutting of the tree branch due to the too low position of the serrated disk 365.

[0106] The support rod 211 is provided with at least two threaded holes 214 for the first screw rod 521 or the second screw rod 531 to pass through.

[0107] In the present invention, the positioning member 1 51 is arranged on the mobile bracket 33, and the electric wire 42 passes through the positioning ring 512 to prevent the sawtooth disk 365 from causing damage to the electric wire, thereby ensuring the safety of electricity use. The positioning member 2 52 and the positioning member 3 53 are installed on the support rod 211 to restrain and fix the electric wire 42, to prevent the electric wire 42 from winding and shaking, and to avoid interference caused by the shaking of the electric wire 42 during the cutting process. At the same time, during non-working hours, after unplugging the plug 43, the electric wire 42 can be wound around the electric wire positioning part 5 for storage.

[0108] In the present invention, the positioning plate 522 is adjusted to clamp the wire 42, which has a good clamping effect, but the operation is complicated; the positioning clamp 532 is easy to use, but there is a possibility of detachment. Therefore, the positioning member 2 52 and the positioning member 3 53 can be used appropriately according to actual conditions.
