liquid on the inner wall of the needleless injector 2 needs to be washed cleanly by the saline injection mechanism 7, the influence of medicine liquid mixing on the treatment effect of livestock is avoided, the user needs to pull the second pull ring 704 rightwards, the second pull ring 704 drives the second pull rod 703 to move rightwards, the second pull rod 703 drives the second baffle 702 to move rightward, at this time, the second return spring 705 is stretched, due to the limitation of the first saline check valve 707 and the second saline check valve 709, the normal saline in the water tank 5 is sucked into the second liquid containing box 701 by the second suction pipe 706, then the user can release the second pull ring 704, under the action of the second return spring 705, the second pull ring 704 drives the second pull rod 703 to move leftward, the second pull rod 703 drives the second baffle 702 to move leftward, due to the limitation of the first saline check valve 707 and the second saline check valve 709, the normal saline in the second liquid containing box 701 is injected into the needleless injector 2 through the second discharge pipe 708, the normal saline is injected into the livestock body by the needleless injector 2, the above steps are repeated several times, so as to ensure that the previous residual liquid medicine inside the needleless injector 2 is washed cleanly, then, a new medicine liquid can be injected into the needleless injector 2 by using the medicine injection mechanism 6, so that the medicine liquid can be prevented from being mixed in the needleless injector 2, the treatment effect of medicine injection treatment on livestock is reduced due to the mutual action of the medicine liquid, in the process of medicine injection treatment, the anti-biting mechanism 8 can prevent the livestock from biting the needle tube, the rubber plate 803 is softer, teeth of the livestock can be protected, meanwhile, the biting force channel of the livestock is slowed down, when the livestock is subjected to treatment and resists biting on the rubber plate 803, the rubber plate 803 and the sliding rod 804 move downwards, the supporting spring 810 is extruded, the supporting spring 810 can slow down the biting speed of the livestock, when the rubber plate 803 moves downwards, the two connecting rods 809 are close to one end of the sliding blocks 806 to the middle, the two sliding blocks 806 are pushed to move to the middle, the third restoring spring 807 can also slow down the biting speed of the livestock, after the rubber plate is bitten by one end distance, the two limiting plates 808 respectively prop against the sliding blocks 806 which are not connected with the supporting sleeve 802 and the sliding rod 804, so that the two sliding blocks 806 are prevented from moving, the connecting rod 809 is further limited to move, the rubber plate 803 is ensured not to move any more, at the moment, the broken needle tube cannot be bitten by livestock, the mouth of the livestock is prevented from being scratched by the broken needle tube, after the medicine filling technology, the device needs to be disinfected and cleaned by using disinfection alcohol and clean water, and particularly, the interior of the needleless injector 2 and the interior of the first liquid containing box 601 are convenient for a user to use next time.
