[0038] Please refer to Figure 1-6 , a portable greening pruning device, comprising a right blade 1 and a left blade 2;

[0039] The lower ends of the right blade 1 and the left blade 2 are connected to a first handle 5 and a second handle 4 respectively, and the middle of the upper sides of the first handle 5 and the second handle 4 is connected to a compression spring 8;

[0040] A rotating shaft 6 is provided at the middle connecting position on the lower side of the right blade 1 and the left blade 2. A one-way valve 12 is provided inside the left side of the first handle 5. An air bag 18 is provided on the right side of the one-way valve 12. An extrusion rod 11 is provided on the right side of the air bag 18.

[0041] An extrusion air cavity 15 is provided at the connection position between the upper side of the air bag 18 and the right blade 1 , and a plurality of air passages 17 are provided between the inner side of the right blade 1 and the extrusion air cavity 15 . The plurality of air passages 17 are provided with jet ports 16 at the connection position on the surface of the right blade 1 .

[0042] A cutting surface 3 is provided at the upper left side of the right blade 1 , and the outer sides of the first handle 5 and the second handle 4 are respectively wrapped and connected with rubber pads.

[0043] In this embodiment, when the operator is using it, he can hold the first handle 5 and the second handle 4, and use the external force applied by the hands to make them rotate relative to each other around the rotating shaft 6. Since the right blade 1 is connected to the first handle 5 and the left blade 2 is connected to the second handle 4, the right blade 1 and the left blade 2 will also open and close around the rotating shaft 6, just like conventional scissors, the branches of green plants are cut and trimmed by opening and closing the blades, and the extrusion spring 8 connected between the first handle 5 and the second handle 4 can use its own elastic force to restore the blades to the initial open state when the handle is released, so as to facilitate the next trimming operation.

[0044] like Figure 1-5As shown, the lower ends of the right blade 1 and the left blade 2 are respectively provided with a connecting blade block 14, and the right blade 1 and the left blade 2 are respectively connected to the first handle 5 and the second handle 4 through the connecting blade block 14 by a plug-in connection method, and the extrusion air cavity 15 is specifically a section of plastic air tube, and the extrusion air cavity 15 is connected to the air channel 17 in the right blade 1 by a sleeve connection method, and is an integral structure with the airbag 18, the airbag 18 is a hollow structure, the airbag 18 is connected to the one-way valve 12, the direction of the one-way valve 12 is from the outside to the inside, the inside of the airbag 18 is filled with gas, and a connecting block 19 is provided at the connection position of the airbag 18 and the extrusion rod 11, and the connecting block 19 is connected to the extrusion rod 11 by a bolt connection method, and the extrusion rod 11 protrudes from the first handle 5, the right blade 1, the first handle 5 and the left blade 2, the second handle 4 are respectively rotated by the rotating shaft 6, and the length of the extrusion rod 11 protruding from the first handle 5 is greater than the length after the first handle 5 and the second handle 4 are combined by the rotating shaft 6.

[0045] Preferably, during operation, when the operator closes the first handle 5 and the second handle 4, the squeezing rod 11 is contacted by the second handle 4 and moves inward from the first handle 5. The squeezing rod 11 squeezes the airbag 18 connected thereto (the airbag 18 is firmly connected to the squeezing rod 11 via the connecting block 19). After the gas inside the airbag 18 is squeezed, since the one-way valve 12 is oriented from the outside to the inside, the gas does not flow out of the one-way valve 12 in the opposite direction. Instead, the gas flows through the squeezing air cavity 15 connected to the airbag 18. The squeezing air cavity 15 directs the gas into the multiple air channels 17 formed on the inner side of the right blade 1. The gas is then ejected from the air outlets 16 on the surface of the right blade 1 through the air channels 17. The ejected gas can blow away debris such as branch and leaf debris left on the blade during pruning and remove residual plant juice, thereby cleaning the blade, allowing the blade to maintain good cutting performance and preventing debris from affecting the pruning effect or causing damage to the blade.

[0046] like Figure 1 as well as Figure 3 and Figure 6 As shown, a replacement blade 10 is provided at the upper right side of the left blade 2, a plurality of connection replacement bolts 13 are provided at the connection position between the replacement blade 10 and the left blade 2, and a blade side surface 9 is provided on the right side outside of the replacement blade 10.

[0047] Preferably, when the blade of the left blade 2 is worn and needs to be replaced, the multiple connection replacement bolts 13 at the connection position between the replacement blade 10 and the left blade 2 can be unscrewed, the old replacement blade 10 can be removed, and then replaced with a new replacement blade 10, and then re-fixed with the connection replacement bolts 13 to ensure that the replacement blade 10 can be firmly installed on the left blade 2 and continue to participate in the pruning work.

[0048] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
