Therefore, the invention can cut off the blades on two sides which are distributed oppositely in one direction at one time without separate cutting off, thereby reducing operation steps, improving the working efficiency of the dense leaf cutting process, and being especially suitable for plant cutting with shorter branch internodes and denser branches and leaves.
With continued reference to fig. 1, the present invention further provides that one of the first and third blades 6, 5 is provided with one blade 8 on the back side, and the other blade 8 is provided on the back side of one of the second and fourth blades 9, 7. Optionally, the pallet 8 is provided with lightening holes to avoid the shears being heavy and inconvenient to operate. The blade 8 is located on the opposite side to the blade so as not to interfere with shearing. The upper end of the pallet 8 provided at the back of the first scissor blade 6 or the back of the second scissor blade 9 protrudes upward, and the lower end of the pallet 8 provided at the back of the third scissor blade 5 or the back of the fourth scissor blade 7 protrudes downward. I.e. the upper end of the lower pallet 8 is higher than the first 6 and second 9 blades and the lower end of the upper pallet 8 is lower than the third 5 and fourth 7 blades. Because the first shearing blade 6 and the third shearing blade 5 are positioned on the same side, and the second shearing blade 9 and the fourth shearing blade 7 are positioned on the same side, the two supporting plates 8 are distributed oppositely left and right, and the two supporting plates 8 are all protruded, so that a clamping area can be formed between two edges of the two groups of shearing blades, when the blade is sheared off from the sealed leaf cutting blade, the cutting blade is positioned between the two supporting plates 8, so that the two supporting plates 8 support and clamp the cutting blade, when the branches and leaves are sheared off, the cutting blade is firstly supported by the supporting plates 10, the cutting blade is supported by the cutting blades without extending a handle between the shearing blades, the stability of shearing operation can be improved, the hand injury is prevented, and the safety of the operation process can be improved.
The foregoing descriptions of specific exemplary embodiments of the present invention are presented for purposes of illustration and description. It is not intended to limit the invention to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching.
