A sliding groove 59 is provided at the bottom of the wedge-shaped push block 53, and the T-shaped shaft 55 passes through the sliding groove 59.

[0027] The alcohol sprayer 57 includes a spray head 571, a connecting pipe 572, and a feed pipe 573. The spray head 571 is arranged in two rows, and the two rows of spray heads 571 are located on both sides of the blade 52. The two rows of spray heads 571 are fixedly installed on the outer wall of the sliding seat 51, the connecting pipe 572 is fixedly installed inside the sliding seat 51, the spray head 571 is connected to the connecting pipe 572, and the feed pipe 573 is fixedly installed at the bottom end of the connecting pipe 572.

[0028] The drug extruder 58 includes a high-pressure drug storage bin 581 disposed between two groups of connecting pipes 572. A drug outlet hole 582 is provided at the bottom of the blade 52. A control valve 583 is installed between the high-pressure drug storage bin 581 and the drug outlet hole 582. The connecting pipe 572 and the high-pressure drug storage bin 581 are respectively connected to two groups of feed hoses 454.

[0029] A sliding block 586 is movably inserted at the end of the sliding seat 51, a support cylinder 585 is fixedly set inside the sliding seat 51, a lifting spring 587 is set at the inner bottom of the support cylinder 585, the bottom end of the sliding block 586 is movably inserted inside the support cylinder 585, and a roller 584 is rotatably connected between the two groups of sliding blocks 586, and the roller 584 is slidably connected inside the valve handle of the control valve 583.

[0030] Working principle: When the device is used, a colloid drug is poured into the inside of the colloid drug tube 3. The drug adopts chlorpyrifos as the main material and is mixed with starch and water to make a colloid. Then a slidable piston is installed at the end of the colloid drug tube 3. Then the colloid drug tube 3 is installed at the bottom of the pruning pliers 1. Then the alcohol tank 2 filled with alcohol is installed on the top of the pruning pliers 1 to complete the assembly. Before pruning, the pull rod 41 is repeatedly and slightly pulled several times, so that the pull rod 41 drives the two groups of piston rods 452 to move backward, so that negative pressure is formed inside the piston cylinder 451. At this time, the materials inside the alcohol tank 2 and the colloid drug tube 3 are pumped into the piston cylinder 451 through the one-way valve 455, and then transported to the feed pipe 573 and the high-pressure drug storage bin 581 through the feed hose 454. The alcohol entering the feed pipe 573 is then sprayed outward through the spray head 571 to pre-disinfect the blade 52, and the colloid drug entering the high-pressure drug storage bin 581; Since the pulling amplitude of the pull rod 41 is small, the sliding blocks 586 on both sides are not in relative compression contact, so the control valve 583 is not opened. At this time, the colloid is stored inside the high-pressure medicine storage bin 581, forming a high pressure, waiting for discharge; When pruning, by pulling the pull rod 41 to the bottom, the pull rod 41 drives the two groups of wedge-shaped push blocks 53 to move backward through the traction cable 54, and the wedge-shaped push block 53 squeezes the sliding seat 51 toward the middle, so that the memory spring 56 is compressed, and the sliding seat 51 moves outward from the inside of the pruning pliers 1. At this time, the two groups of blades 52 are stacked up and down, and the vines are cut. The workers take the cut vines away for collection. At the same time, in this process, the sliding blocks 586 on both sides are against each other, so that the sliding blocks 586 move into the support tube 585, so that the lifting spring 587 is compressed. At this time, the sliding block 586 drives the valve handle on the outer surface of the control valve 583 to rotate through the roller 584, so that the control valve 583 is opened, so that while cutting, the gelatinous medicine is applied to the root of the vine through the medicine outlet 582, and the sterilizing effect can be achieved through the sterilizing spirit. At the same time, the gelatinous medicine wraps the cut wound of the vine to avoid cross infection; At the same time, in the above process, the pull rod 41 drives the piston rod 452 to move outward, so that negative pressure is formed inside the piston cylinder 451. At this time, the materials inside the alcohol tank 2 and the colloid drug tube 3 are pumped into the piston cylinder 451 through the one-way valve 455, and the reset spring 42 is compressed. Then the pull rod 41 is released, and under the action of the reset spring 42, the piston rod 452 moves toward the inside of the piston cylinder 451, so that the material delivery hose 454 is transported to the feed pipe 573 and the high-pressure drug storage bin 581. At the same time, the memory spring 56 pushes the two sets of sliding seats 51 to move to both sides and reset. At this time, the blade 52 is removed from the vine, and the lifting spring 587 pushes the sliding block 586 to move outward, so that the roller 584 is reset and drives the control valve 583 to close. Then the spray head 571 sprays alcohol to disinfect the blade 52 when it is reset. At the same time, the colloid drug enters the high-pressure drug storage bin 581, so that the high-pressure drug storage bin 581 is replenished with drugs, maintains a high pressure state, and waits for the next pruning to be carried out for drug coating.

[0031] By pulling the pull rod, the pull rod drives the two sets of wedge-shaped push blocks to move backward through the traction cable, and the wedge-shaped push blocks squeeze the sliding seat toward the middle, so that the memory spring is compressed, and the sliding seat moves out from the inside of the pruning pliers. At this time, the two sets of blades are stacked up and down to complete the cutting of the vines. The workers take the cut vines away for collection. At the same time, in this process, the sliding blocks on both sides resist each other, so that the sliding blocks move toward the inside of the support tube, so that the lifting spring is compressed. At this time, the sliding block drives the valve handle on the outer surface of the control valve to rotate through the roller, so that the control valve is opened. At the same time, the vine root is coated with a gelatinous drug through the drug outlet hole while cutting, and the sterilization spirit can achieve a sterilization effect. At the same time, the gelatinous drug wraps the cut wound of the vine to avoid cross infection.

[0032] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
