This operation method increases the operator's workload and requires high skills. In addition, since the trees are tall, people need to use aerial platforms, ladders or climbing methods to reach the operation location, which is a high-risk operation and poses safety risks. Therefore, in order to realize the mechanization of landscape tree maintenance, a multi-degree-of-freedom work tool posture adjustment mechanism is needed to perform multi-degree-of-freedom adjustment of the work tools to meet the use requirements of the work tools.

[0025] This embodiment provides a multi-degree-of-freedom work tool posture adjustment mechanism, which realizes multi-degree-of-freedom posture adjustment of the work tool, adapts to the flexibility requirements of the work tool posture caused by the irregular posture of tree branches, and thus provides a premise for the mechanization of landscape tree maintenance, so as to reduce the operator's work intensity, reduce the operator's safety hazards, improve work efficiency, and meet the use requirements of the work tool.
[0026] Combine Figures 1 to 3 As shown, the multi-degree-of-freedom work tool posture adjustment mechanism of this embodiment includes a fixing member 10, a mounting bracket 20, a driving unit 30 and a tool body 40. The fixing member 10 is connected to the external structure, and the work tool posture adjustment mechanism of this embodiment is installed on the external structure, while the mounting bracket 20 installs the driving unit 30. The tool body 40 is located at the end of the driving unit 30, and the driving unit 30 realizes partial adjustment of the tool body 40.
[0027] In this embodiment, the tool body 40 is a cutting tool, a shearing tool, a picking tool, etc., and the corresponding tool can be selected according to the maintenance requirements of the landscape trees.
[0028] Combine Figure 1 and Figure 2 As shown, the mounting bracket 20 of this embodiment is connected to the fixing member 10 through the first driving joint 21 to rotate the mounting bracket 20 relative to the fixing member 10. The driving part 30 is located on the mounting bracket 20. The driving part 30 includes a telescopic joint 31, a second driving joint 32 and a third driving joint 33. The telescopic joint 31, the second driving joint 32 and the third driving joint 33 are connected in sequence and can be driven independently. The tool body 40 is installed on the third driving joint 33, and the tool body 40 is driven by the third driving joint 33. The tool body 40 of this embodiment is adjusted in position by the driving part 30, and the driving part 30 is located on the mounting bracket 20, and the mounting bracket 20 can be rotated relative to the fixing member 10, thereby realizing multi-degree-of-freedom adjustment of the tool body 40 to meet the use requirements of the tool body 40.
[0029] In this embodiment, the first drive joint 21, the second drive joint 32 and the third drive joint 33 are all rotating joints. Under the cooperative drive of the second drive joint 32 and the third drive joint 33, the machine body 40 is rotated in two directions, and the first drive joint 21 realizes the rotation of the mounting bracket 20 to further improve the displacement freedom of the machine body 40.
[0030] Specifically, the first driving joint 21 , the second driving joint 32 and the third driving joint 33 of this embodiment can be implemented by using a hydraulic cylinder, a pneumatic cylinder or an electric cylinder.
[0031] like Figure 2 As shown, the telescopic joint 31 of this embodiment includes a fixed outer arm 311 and a telescopic inner arm 312. The telescopic inner arm 312 is located inside the fixed outer arm 311 and is telescopic along the length direction of the fixed outer arm 311.

[0032] In this embodiment, a driver 50 is provided on the mounting bracket 20, and the end of the driver 50 is connected to the telescopic joint 31. An angle is formed between the driver 50 and the telescopic joint 31 to drive the telescopic joint 31 to tilt. The driver 50 of this embodiment is one of a hydraulic cylinder, a pneumatic cylinder or an electric cylinder. The driver 50 can drive the telescopic joint 31, change the angle of the telescopic joint 31, and further adjust the position of the machine body 40.
[0033] Specifically, the included angle between the telescopic joint 31 of this embodiment and the vertical plane of the rotation axis of the mounting bracket 20 is 0-60°. Within this angle range, the tool body 40 can be effectively adjusted.
[0034] In actual use, the multi-degree-of-freedom work tool posture adjustment mechanism of this embodiment is installed and connected with a fixing part 10, and the mounting bracket 20 can rotate relative to the fixing part 10. The driving part 30 is located on the mounting bracket 20, and the tool body 40 is position-adjusted by the driving part 30, and the driver 50 adjusts the angle of the telescopic joint 31 of the driving part 30, thereby realizing multi-degree-of-freedom adjustment of the tool body 40 and meeting the use requirements of the tool body 40.
[0035] In summary, the multi-degree-of-freedom work tool posture adjustment mechanism of this embodiment realizes multi-degree-of-freedom posture adjustment of the work tool, adapts to the flexibility requirements of the work tool posture due to the irregular posture of tree branches, and thus provides a premise for the mechanization of landscape tree maintenance, so as to reduce the operator's work intensity, reduce the operator's safety hazards, improve work efficiency, and meet the use requirements of the work tool.
