[0026] Adjusting mechanism 4 includes sliding slot 41, threaded rod 42 and extension handle 43, sliding slot 41 is set in the lower end of connecting handle 1, threaded rod 42 is rotationally connected with connecting handle 1, and threaded rod 42 side is threadedly connected with extension handle 43, threaded rod 42 is rotationally arranged in the inboard of sliding slot 41, and extension handle 43 is slidably arranged in the inboard of sliding slot 41, the length of extension handle 43 can be adjusted according to actual use demand in the use process of the device, threaded rod 42 is rotated, and extension handle 43 is slidably telescoped in the inboard of sliding slot 41 by the rotation of threaded rod 42, so that the device is suitable for different use scenarios, and different use demands are met.
[0027] The limiting mechanism 5 comprises a limiting groove 51, a limiting block 52 and a supporting spring 53. The limiting grooves 51 are symmetrically arranged on the two sides of the inner part of the sliding groove 41. The limiting blocks 52 are symmetrically arranged on the side edges of the extension handle 43 and are slidably arranged in the limiting grooves 51. The supporting spring 53 is arranged on the side edge of the threaded rod 42 and is connected to the upper wall of the inner part of the sliding groove 41 and the upper surface of the extension handle 43. During the extension and retraction of the extension handle 43, the limiting block 52 slides in the limiting groove 51, so as to avoid the upper end of the extension handle 43 from falling off when it slides to the lowermost end of the sliding groove 41.
[0028] The replacement mechanism 6 comprises a blade 61, a limiting rod 62, a clamping block 63, a clamping groove 64, a circular groove 65, a limiting bolt 66, a nut 67 and a return spring 68. The blade 61 is arranged on the side edge of the connecting column 3. The limiting rod 62 is arranged on the side edge of the blade 61 and is symmetrically provided with the clamping block 63. The clamping grooves 64 are symmetrically arranged on the side edge of the blade 61.

During use, the blade 61 is installed on the side edge of the connecting column 3. When the blade 61 is no longer sharp after long-term use, the nut 67 is rotated, the return spring 68 pushes the limiting rod 62 to move, the clamping block 63 is gradually separated from the clamping groove 64, the blade 61 that is no longer sharp is removed, a new blade 61 is replaced on the side edge of the connecting column 3, the nut 67 is reversely rotated to drive the limiting rod 62 to limit the new blade 61, the clamping block 63 is clamped with the clamping groove 64 on the side edge of the blade 61, the replacement is completed, and the service life of the device is prolonged.
[0029] Working principle: according to Figures 1 to 3 During use, the extension length of the extension handle 43 can be adjusted according to actual use requirements. The threaded rod 42 is rotated to drive the extension handle 43 to slide and extend or retract in the sliding groove 41, so as to facilitate the device to be suitable for different use scenarios and meet different use requirements. When a tree branch that is difficult to cut is encountered during use, the threaded rod 42 is rotated to adjust the extension and retraction of the extension handle 43, so as to change the power arm of the device and facilitate the cutting of the tree branch.
[0030] According to Figures 3 to 4In the process of extending the handle 43, the limiting block 52 slides in the limiting groove 51, so as to avoid the upper end of the handle 43 from falling off when the upper end of the handle 43 slides to the lower end of the sliding groove 41, and when the handle 43 is in the sliding groove 41, the supporting spring 53 is in a compressed state, and when the handle 43 is extended, the supporting spring 53 is stretched, so as to press the handle 43, so that the friction between the handle 43 and the threaded rod 42 is increased, so that the handle 43 is in a fastened state, avoiding the handle 43 from loosening during use;
[0031] According to Figures 5 to 6 In the process of use, the blade 61 is installed on the side of the connecting column 3, when the blade 61 is no longer sharp after long-time use, the nut 67 is rotated, and then the limiting rod 62 is pushed to move by the reset spring 68, and the clamping block 63 is gradually separated from the clamping groove 64, when the nut 67 is continuously rotated to separate the clamping block 63 from the clamping groove 64, the blade 61 which is no longer sharp is removed, and then a new blade 61 is replaced on the side of the connecting column 3, and then the nut 67 is reversely rotated to drive the limiting rod 62 to limit the new blade 61, and the clamping block 63 is clamped with the clamping groove 64 on the side of the blade 61, so that the replacement is completed, and the service life of the device is improved.
