[0013] The drawings in this utility model are all schematic diagrams, and their sizes do not represent actual sizes;

[0014] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0015] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0016] like Figure 1-2 As shown, a fruit tree branch pruning device comprises a main scissor blade 1 and an auxiliary scissor blade 2, wherein the main scissor blade 1 and the auxiliary scissor blade 2 are hinged by a rotating shaft 3, a spring 4 is arranged between the main scissor blade 1 and the auxiliary scissor blade 2, a stabilizing frame 5 is arranged outside one end of the rotating shaft 3, the main body of the stabilizing frame 5 is a spring steel circular ring with an upward opening, the opening of the stabilizing frame 5 gradually widens from the edge of the circular ring outward, and the lower ends of the main scissor blade 1 and the auxiliary scissor blade 2 are fixedly connected with a telescopic handle. The branches to be pruned are squeezed into the circular ring of the stabilizing frame 5 from the opening of the stabilizing frame 5, so that the branches to be pruned can be stably placed in the main scissor blade 1 and the auxiliary scissor blade 2, and are not easy to slide out, and do not need to be fixed separately.

[0017] The telescopic handle comprises: an outer handle 6 and an inner handle 7. The outer handle 6 is provided with a plurality of slots 8. A limiting device 9 is provided at the top of the inner handle 7. The outer handle 6 is sleeved outside the inner handle 7. The outer handle 6 and the inner handle 7 are connected through the slots 8 via the limiting device 9. The two outer handles 6 are respectively connected to the main scissor blade 1 and the auxiliary scissor blade 2. The limiting device 9 is connected to the slots 8 at different positions to adjust the length of the telescopic handle.

[0018] The limiting device 9 includes: a limiting base 90, both ends of the limiting base 90 are connected to limiting springs 91, and the outer ends of the limiting springs 91 are connected to limiting blocks 92 that cooperate with the slots 8. After the limiting blocks 92 are pressed, the limiting springs 91 are compressed, and the limiting blocks 92 are pressed into the inner part of the outer layer handle 6, and the inner layer handle 7 is moved to adjust the length of the telescopic handle. When the limiting device 9 moves to other slots 8, the limiting springs 91 rebound, and the limiting blocks 92 are stuck in the slots 8 to fix the outer layer handle 6 and the inner layer handle 7.

[0019] The bottom end of the telescopic handle fixedly connected to the main scissor blade 1 is provided with a first handle cover 10, and the first handle cover 10 is connected to the bottom of the inner handle 7. The bottom end of the telescopic handle fixedly connected to the auxiliary scissor blade 2 is provided with a second handle cover 11, and the second handle cover 11 is connected to the bottom of the inner handle 7. A clamping block 12 is fixedly connected to the first handle cover 10, and a buckle 13 is rotatably connected to the second handle cover 11. When the clamping block 12 is engaged with the buckle 13, the main scissor blade 1 and the auxiliary scissor blade 2 fit tightly. When the clamping block 12 passes through the buckle 13, due to the elasticity of the spring 4, the clamping block 12 and the buckle 13 are automatically tightened and engaged, which facilitates the storage and carrying of the device and prevents the blades of the scissors from damaging the storage tool or scratching the user.

[0020] The inner side of the stabilizing frame 5 is provided with transverse ribs to ensure that the branches are not easy to slide out.

[0021] Working principle: When using the utility model, separate the main scissor blade 1 and the auxiliary scissor blade 2, insert the branch to be pruned into the stabilizing frame 5 from the opening, and then prune the branch; when the length of the telescopic handle needs to be adjusted, press the limit devices 9 on both sides of the telescopic handle, pull the inner handle 7 to make the limit devices 9 engage with the card slots 8 at other positions; after use, rotate the buckle 13, and engage the card block 12 through the buckle 13, so that the main scissor blade 1 and the auxiliary scissor blade 2 fit tightly.

[0022] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the utility model, or are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
