[0002] Sugar apple is a deciduous small tree of the genus Annona in the family Annonaceae. It looks like a lychee, hence the name "sugar apple". The fruit is made up of many mature ovaries and receptacles, just like a Buddha's head, so it is also known as Buddha's head fruit and sugar apple. During the planting process of sugar apple, its branches need to be pruned.

[0003] The existing Chinese patent CN219961426U discloses a device for pruning sugar-apple branches. The device for pruning sugar-apple branches can cut off the branches by bringing a first blade and a second blade close to each other, thereby pruning the branches of the sugar-apple tree. The driving mechanism can drive the rotating shaft and the first blade to rotate, and the telescopic mechanism can drive the first blade and the second blade to move up and down, so as to facilitate pruning the branches at a higher position of the sugar-apple tree. The reduction motor, the active bevel gear and the driven bevel gear can drive the rotating shaft to rotate, and the servo motor and the transmission rod drive the threaded block to rotate on the inner wall of the threaded sleeve to drive the first blade and the second blade to move up and down.

[0004] The above-mentioned device for pruning sugar apple branches needs to be held by hand when in use, and two motors and corresponding structures are arranged in the device, which makes the whole device heavy, imposes a heavy burden on the user, and easily causes fatigue to the user's arm.

A pruning component 305 is fixedly installed on the top of the extension rod 304. The top port of the three-way valve 303 is connected through The pipeline is connected to the interior of the long pole 2. By arranging the circulating air pump 302 as a driving component on the cart 301, it is not necessary to lift the circulating air pump 302 during pruning, which reduces the physical exertion of the user. The high-pressure gas in the circulating air pump 302 is introduced into the long pole 2 through the three-way valve 303, so that the gas pushes the piston 306 to rise, thereby driving the extension rod 304 to rise, so that the pruning component 305 rises, and the height of the pruning component 305 is adjusted to prune branches of different heights. The spring 308 is arranged so that after the circulating air pump 302 extracts the gas in the long pole 2, the spring 308 can push the piston 306 to move downward, thereby moving the pruning component 305 downward;

[0024] The pruning component 305 includes a shell 3057, which is fixedly mounted on the top of the extension rod 304. A pneumatic telescopic rod 3051 is fixedly mounted on the inner wall of the shell 3057.

A pneumatic telescopic rod 3051 with a smaller volume and weight is used as a driving component during the pruning process. Compared with a motor, it can ensure a lighter weight under the premise of providing the same power. The pneumatic telescopic rod 3051 drives the L-shaped rack 3052 to move horizontally, thereby driving the gear 3053 to rotate, so that the rotating shaft 3054 rotates, and then drives the blade 1 3055 to rotate, so that the blade 1 3055 and the blade 2 3056 are closed to prune the branches;
