The standing frame 1 is connected to the telescopic arm, the base plate 3 is arranged on the standing frame 1, and the cutting module 2 is arranged on the base plate 3.

[0043] A sliding module is provided between the base plate 3 and the standing frame 1 , which enables the base plate 3 to move along multiple directions of the standing frame 1 .

[0044] In this embodiment, the cutting device is applied to an aerial work vehicle, which includes a telescopic arm, and the cutting device includes a standing frame 1, a cutting module 2 and a base plate 3. The cutting module 2 includes a cutting saw blade 22. The standing frame 1 is connected to the telescopic arm, the base plate 3 is arranged on the standing frame 1, and the cutting module 2 is arranged on the base plate 3. In this embodiment, a sliding module is arranged between the base plate 3 and the standing frame 1, which enables the base plate 3 to move in multiple directions along the standing frame 1. The sliding module can enable the base plate 3 to move synchronously with the cutting module 2 in multiple directions on the standing frame 1. Therefore, when the operator cuts trees by moving the cutting module 2 in the standing frame 1, the base plate 3 always supports the cutting module 2. Therefore, the cutting device of this embodiment reduces the labor intensity of the workers and reduces the occurrence of safety accidents.

[0045] In some embodiments, the sliding module includes a first guide rail 41, a first slider 42, and a housing 45. The first guide rail 41 is disposed on the bottom plate of the stand frame 1 and extends along the length of the stand frame 1. The first slider 42 is slidably disposed on the first guide rail 41.

In this embodiment, the first guide rail 41, which is disposed on the bottom plate of the stand frame 1 and extends along the length of the stand frame 1, cooperates with the first slider 42 disposed on the base plate 3 to enable the cutting module 2 on the base plate 3 to move along the length of the stand frame 1. This structure provides high guidance precision and smooth movement, reducing worker labor intensity and the occurrence of safety accidents.

[0046] In some embodiments, the sliding module further includes a second guide rail 43 and a second slider 44.

[0047] In some embodiments, the standing frame 1 has a longitudinally extending crossbar 11, and the housing 45 has a guide hole 451, into which the crossbar 11 is inserted. In this embodiment, by inserting the longitudinally extending crossbar 11 of the standing frame 1 through the guide hole 451 of the housing 45, the cutting module 2 follows the substrate 3 in the longitudinal direction of the standing frame 1.

[0050] This embodiment realizes 360° rotation of the substrate 3 by arranging a second turntable 52 and a first turntable 51 that coaxially rotate with each other between the substrate 3 and the second slider 44, thereby realizing 360° rotation of the cutting module 2 on the standing frame 1, so that the cutting module 2 has the ability to rotate horizontally 360°.

[0051] In some embodiments, the cutting device further includes a telescopic module, the telescopic module including a first support rod 61 provided on a side of the first base plate 3 away from the first turntable 51 and a second support rod 62 telescopically matched with the first support rod 61, the cutting module 2 is provided on the second support rod 62;

[0052] The extension and retraction direction of the second support rod 62 is perpendicular to the bottom plate of the standing frame 1 .

[0055] In this embodiment, one end of the connecting rod 8 is rotatably set on the second support rod 62, the cutting module 2 is set at the end of the connecting rod 8 away from the second support rod 62, and the two ends of the shock-absorbing module 7 are respectively connected to the connecting rod 8 and the second support rod 62. The shock-absorbing system of the shock-absorbing module 7 is used to absorb the shock of the cutting module 2, buffer the operating vibration, and improve the user's operating experience.

[0056] The top of the second support rod 62 has an inclined portion inclined toward the side away from the connecting rod 8 , and both ends of the shock absorbing module 7 are respectively connected to the connecting rod 8 and the inclined portion, forming a triangular shock absorbing structure at the top of the second support rod 62 .

[0057] In some embodiments, the shock absorbing module 7 includes a cylinder 71 and a piston 72 disposed in the cylinder 71;

[0058] The cylinder 71 is rotatably connected to the connecting rod 8, and the piston 72 is rotatably connected to the second support rod 62; or, the cylinder 71 is rotatably connected to the second support rod 62, and the piston 72 is rotatably connected to the connecting rod 8.

The damping module 7 can be a hydraulic or pneumatic damping module, which can absorb more than 80% of the vibration.

[0060] In some embodiments, the cutting device further comprises a rotating rod 9, which is rotatably disposed at an end of the connecting rod 8 away from the second support rod 62, and the cutting module 2 is disposed at the lower end of the rotating rod 9;

[0062] In this embodiment, the rotating rod 9 is rotatably set at the end of the connecting rod 8 away from the second support rod 62, and the cutting module 2 is set at the lower end of the rotating rod 9. Since the rotation axis of the rotating rod 9 is perpendicular to the bottom plate of the standing frame 1, the structure of this embodiment enables the cutting module 2 to rotate horizontally at the lower end of the rotating rod 9, which is convenient for users to operate the cutting module 2.

[0063] In some embodiments, the cutting device further includes a rotating sleeve 21, a rotating shaft 91 is provided at the lower end of the rotating rod 9, and the rotating shaft 91 is passed through the rotating sleeve 21, and the rotating sleeve 21 is connected to the top of the cutting module 2.

[0065] In this embodiment, the rotating shaft 91 mounted on the lower end of the rotating rod 9 is hung by the rotating sleeve 21 on the top of the cutting module 2. On the one hand, this facilitates the disassembly of the cutting module 2. On the other hand, since the rotating shaft 91 is parallel to the length direction of the standing frame 1, the cutting module 2 rotates around the rotating shaft 91, making it easier for the user to operate the cutting module 2.

[0066] An annular groove may be provided on the rotating shaft 91 , and the rotating sleeve 21 is hung in the annular groove to prevent the cutting module 2 from falling.
