DETAILED DESCRIPTION

[0021] In order to further illustrate the technical means and effects adopted by the utility model to achieve the predetermined utility model purposes, the specific embodiments, structures, features and effects of the utility model will be described in detail below in combination with the drawings and preferred embodiments.

[0022] This embodiment provides a fruit tree branch pruning device, including a first leg 1 and a first cutter 2 fixedly disposed at one end of the first leg 1, a second leg 3 and a second cutter 4 fixedly disposed at one end of the second leg 3, the first leg 1 and the second leg 3 being rotatably connected, and also including a first limiting group and a second limiting group, the first limiting group being disposed on the front end surface of the first cutter 2, and the second limiting group being disposed on the front end surface of the second cutter 4. When the first leg 1 and the second leg 3 are rotated in opposite directions, the first cutter 2 and the second cutter 4 open, locking the pomelo branch to be pruned, and the first limiting group and the second limiting group intercept the pomelo branch between the first cutter 2 and the second cutter 4. When the first leg 1 and the second leg 3 are rotated in opposite directions, the first cutter 2 and the second cutter 4 close, cutting off the pomelo branch.

[0023] The first limiting assembly includes a first locking body 5, which is rotatably mounted on the upper surface of the end of the first cutter 2 via a rotating shaft. A torsion spring is provided around the outer ring of the rotating shaft for resetting the first locking body 5. When no external force is applied, the torsion spring maintains the first locking body 5 extending along the inner side of the first cutter 2. Figure 1 As shown, the branches of the Shatin pomelo tree are blocked to prevent them from sliding out from the first cut 2.

[0024] The inner side of the first card body 5 is fixed with several inclined first protruding teeth 7. The first protruding teeth 7 increase the friction between the first card body 5 and the pomelo branch, further restricting the pomelo branch at the first cutter 2.

[0025] like Figure 4 As shown, the upper surface of the first cutter 2 is provided with a first guide groove 11 and a first spring 13. A first limiting post 12 is slidably provided on the upper surface of the first cutter 2. Both the first limiting post 12 and the first spring 13 are located in the first guide groove 11. One end of the first spring 13 is fixedly connected to the first limiting post 12, and the other end is fixedly connected to the first cutter 2. The first limiting post 12 slides along the first guide groove 11 toward the first spring 13. The first limiting post 12 moves away from the first locking body 5 and does not obstruct the rotation of the first locking body 5. The first locking body 5 is rotated downwards so that it passes over the first guide groove 11, releasing the first limiting post 12. The first spring 13 extends and pushes the first limiting post 12 back to its initial position, blocking the first locking body 5 and storing the first locking body 5 on the first cutter 2 for easy storage. Similarly, the second locking body 6 can be stored on the second cutter 4, as shown. Figure 3 As shown; by operating in the reverse manner, the first locking body 5 can be opened from the first cutter 2, and the second locking body 6 can be opened from the second cutter 4, as follows. Figure 1 and Figure 2 As shown, this makes it easy to hold the pomelos in place.

[0026] The second limiting group includes a second locking body 6, which is rotatably disposed on the lower surface of the end of the second cutter 4.

[0027] The second clamping body 6 is internally fixed with a plurality of inclined second protrusions 8.

[0028] As shown in Figure 5 the lower surface of the second cutter 4 is provided with a second guide groove 14 and a second spring 16, the second spring 16 and a second limiting column 15 are located in the second guide groove 14, the lower surface of the second cutter 4 is slidingly provided with the second limiting column 15, one end of the second spring 16 is fixedly connected with the second cutter 4, and the other end is fixedly connected with the second limiting column 15.

[0029] The end of the first cutter 2 is fixedly provided with a first stop block 9 on the same side of the first clamping body 5 for blocking the outward rotation of the first clamping body 5, so as to prevent the first clamping body 5 from rotating too large and losing the function of limiting the pomelo tree branches; the end of the second cutter 4 is fixedly provided with a second stop block 10 on the same side of the second clamping body 6 for blocking the outward rotation of the second clamping body 6, so as to prevent the second clamping body 6 from rotating too large and losing the function of limiting the pomelo tree branches.

[0030] The first leg 1 and the second leg 3 are reversely rotated, and the first cutter 2 and the second cutter 4 are synchronously rotated with the first leg 1 and the second leg 3 respectively to be opened, as shown in Figure 1 and Figure 2 The first clamping body 5 and the second clamping body 6 respectively clamp the pomelo tree branches to be pruned and intercept the pomelo tree branches between the first cutter 2 and the second cutter 4, the first leg 1 and the second leg 3 are oppositely rotated, the first cutter 2 and the second cutter 4 are closed, and the pomelo tree branches are cut off.

[0031] If the pomelo tree branches are relatively hard, the first clamping body 5 and the second clamping body 6 are pushed to rotate outward during shearing, so as to unload part of the extrusion force of the pomelo tree branches on the first clamping body 5 and the second clamping body 6, and prevent the first clamping body 5 and the second clamping body 6 from being damaged; when the first clamping body 5 and the second clamping body 6 respectively touch the first stop block 9 and the second stop block 10, the first clamping body 5 and the second clamping body 6 are blocked by the first stop block 9 and the second stop block 10 and stop rotating, so as to prevent the first clamping body 5 and the second clamping body 6 from rotating too large and losing the limiting function on the pomelo tree branches.

[0032] The first clamping body 5 and the second clamping body 6 synchronously rotate with the first cutter 2 and the second cutter 4 respectively, so as to clamp pomelo tree branches with different diameters and expand the use range.

[0033] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in any form. Although the present application has been disclosed with preferred embodiments, it is not intended to limit the present application. Any person skilled in the art can make minor changes or modifications to the disclosed technical content, or make equivalent embodiments with equivalent changes, without departing from the technical solution of the present application. Any modification, equivalent change or modification of the above embodiments, which does not depart from the technical solution of the present application, is still within the scope of the technical solution of the present application.
