[0044] The above embodiment discloses an apple tree branch trimmer. When in use, the connecting rotating block 203 is rotated. At this time, the connecting rotating rod 208 drives the moving pressing plate 209 to rotate under the drive of the connecting rotating block 203. At the same time, the connecting rotating rod 208 can stably move along the inner wall of the handle 6 through the threaded connection with the handle 6. At this time, the moving pressing plate 209 is separated from the outer wall of the sliding pressing plate 2010 by moving, so as to release the fixation of the sliding pressing plate 2010 and the handle 6.

[0045] After that, the handle 6 is pulled to be separated from the outer wall of the support cylinder 5. At this time, the moving pull rod 206 drives the moving slider 207 to move synchronously along the inner wall of the support cylinder 5 under the drive of the handle 6. During this process, the moving pull rod 206 slides along the inner wall of the support cylinder 5 and the outer wall of the limit block through the linear sliding groove 205. At the same time, the positioning block 204 slides into the inside of the moving slider 207 under the block of the support cylinder 5. At this time, the limit baffle 201 pushes the lifting push block 2011 to slide along the inner wall of the moving slider 207 through the lifting slide rod 202. At the same time, the limit baffle 201 contracts by moving and pressing the spring 2012. At this time, the sliding pressing plate 2010 slides along the inner walls of the handle 6, the moving pull rod 206, and the moving slider 207 under the extrusion of the lifting push block 2011. When the positioning block 204 moves to the end of the next positioning slot, the spring 2012 pushes the limit baffle 201 through rebound, so that the positioning block 204 can penetrate to the outside of the top of the support cylinder 5, so as to realize the movement limit of the moving slider 207.

[0046] When the moving slider 207 moves to the specified position, the connecting rotating block 203 is rotated at this time and contacts the outer wall of the handle 6. During this process, the connecting rotating rod 208 drives the moving pressing plate 209 to extrude the outer wall of the sliding pressing plate 2010 by rotating. At the same time, the sliding pressing plate 2010 extrudes the outer wall of the lifting push block 2011 along the inner walls of the handle 6, the moving pull rod 206, and the moving slider 207 under the extrusion of the moving pressing plate 209, so as to realize the extrusion fixation of the positioning block 204, effectively avoiding the loosening and reset of the moving slider 207 during use. After that, the same operation is performed on the connecting rotating block 203 at one end of the other connecting block 4, so as to realize the convenient extension of the cutter head 1, which is beneficial to efficiently trimming apple tree branches within a certain height range through the cutter head 1, thereby further improving the efficiency of trimming apple tree branches.

[0047] As described above, it is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
