One end of the handle 5 is welded with an insertion shaft 20.

[0023] In this technical solution, the installation between the mounting shaft 3 and one extension shaft 4 is completed by inserting the insertion shaft 18 of one extension shaft 4 into the insertion hole 10 of the mounting shaft 3, and then rotating the corresponding internal thread sleeve 17 so that it partially rotates into the inside of the threaded shaft 13. Then, the splicing of multiple extension shafts 4 is completed by inserting the insertion shaft 18 of another extension shaft 4 into the insertion hole 19 of the extension shaft 4, and rotating the corresponding internal thread sleeve 17 so that it partially rotates into the inside of the threaded shaft 13. Finally, the installation between the handle 5 and the length adjustment component is completed by inserting the insertion shaft 20 of the handle 5 into the insertion hole 19 of the tail extension shaft 4, and rotating the corresponding internal thread sleeve 17 so that it partially rotates into the inside of the threaded shaft 13. This allows for convenient adjustment of the length adjustment component according to actual needs, thereby adjusting the height of the chain saw. It is convenient to disassemble and carry, and increases the flexibility of use.

[0024] In some technical solutions, such as Figure 1 , Figure 4 and Figure 5 As shown, a servo motor 9 is fixedly installed on the rear side of the chainsaw housing 1, and a switch 23 and a wire roller 24 are fixedly installed on the front side of the chainsaw housing 1. A controller 21 is fixedly installed on one end of the handle 5. The switch 23 is used to control the servo motor 9, and a wire 6 is electrically connected between the switch 23 and the controller 21. Part of the wire 6 is wound around the wire roller 24.

[0025] In use, the loose wire 6 is wound around the roller 24 according to the length of the length adjustment component. The user can control the servo motor 9 to turn on and off by simply using the controller 21 on the handle 5.

[0030] In some technical solutions, such as Figure 5 As shown, a frosted ring 28 is fitted on the threaded shaft 26.

[0031] When in use, the abrasive ring 28 increases the stability of tightening the nut 27.

[0032] In some technical solutions, such as Figure 1 As shown, the handle 5 has several finger grooves 22.

[0033] When in use, the handle 5 is easily gripped via the finger groove 22.

[0034] Working principle: During installation, insert the insertion shaft 18 of one extension shaft 4 into the insertion hole 10 of the mounting shaft 3, and then rotate the corresponding internal thread sleeve 17 so that it partially rotates into the inside of the threaded shaft 13. This completes the installation between the mounting shaft 3 and one extension shaft 4. Then, insert the insertion shaft 18 of another extension shaft 4 into the insertion hole 19 of the extension shaft 4, and rotate the corresponding internal thread sleeve 17 so that it partially rotates into the inside of the threaded shaft 13. This completes the splicing of multiple extension shafts 4. Finally, insert the insertion shaft 20 of the handle 5 into the insertion hole 19 of the tail extension shaft 4. Inside, rotate the corresponding internal threaded sleeve 17 so that part of it rotates into the inside of the threaded shaft 13, thus completing the installation between the handle 5 and the length adjustment component. This allows for easy adjustment of the length adjustment component according to actual needs. Then, according to the length of the length adjustment component, the loose wire 6 is wound around the wire roller 24 to keep the wire 6 taut. During use, the user can control the servo motor 9 to start and stop using the controller 21 on the handle 5. When cutting branches at heights, the chain saw can be controlled without removing the chainsaw housing 1 from the height.
