The inner surfaces of the limiting groove 8 and the movable groove 7 have high smoothness, and when the sliding piece 9 moves, the sliding piece 9 cannot be hindered and cannot shake. After the branches are cut short, the sliding part 9 moves upwards through the limiting groove 8 to release the fixing of the limiting pawl 3 to the gear, and the rotating ratchet 10 drives the movable cutting edge 2 to be separated.
In summary, when the agricultural cutting tool provided by the present invention is used, one hand is used to hold the fixed handle 6, the other hand is used to hold the movable handle 11, and force is applied to the movable handle 11 to rotate the movable handle 11, at this time, the toggle pawl 13 rotatably mounted on the movable handle 11 is engaged with the rotating ratchet 10, so as to push the rotating ratchet 10 to rotate, and the movable blade 2 can move towards the fixed blade 1 under the driving of the rotating ratchet 10 and the movable blade 2. After the movable blade 2 moves, the limiting pawl 3 is meshed with the teeth of the rotating ratchet wheel 10 again in time, so that the rotating ratchet wheel 10 is limited, and the movable blade 2 cannot return to the original position when the hand does not apply force to the movable handle 11, and therefore forward cutting can be continued. The crop branches can be cut by continuously and reciprocally pushing the movable handle 11 to rotate. Therefore, the force application of hands in the trimming process can be reduced, the labor intensity is reduced, and the trimming efficiency is improved.
After one-time trimming is finished, the sliding piece 9 is pulled to enable the sliding piece 9 to move upwards in the limiting groove 8 to the movable groove 7, then the sliding piece 9 slides in the movable groove 7 to one end far away from the rotating ratchet wheel 10, so that the limiting pawl 3 on the sliding piece 9 releases the limiting on the rotating ratchet wheel 10, the rotating ratchet wheel 10 and the movable blade 2 move towards the direction far away from the fixed blade 1 under the action of the torsion spring B15, and preparation is made for the next trimming work.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
