AI Technical Summary
Existing slaughter knives cannot effectively recover clean animal blood, resulting in waste of blood resources.
A slaughtering and blood extraction knife was designed, with an outer and inner knife body made of two stainless steel pipes. The front end of the outer knife body was equipped with a blood inlet hole, and the front end of the inner knife body was a blood inlet port. Blood flowed into the hose through the inner knife body pipe and entered the blood tank.
It is realized that when slaughtering animals, clean blood can be completely recycled and waste of blood resources is avoided.

Abstract
Description
Technical Field
[0001] The present invention relates to a slaughtering tool, specifically a slaughtering knife, and more particularly a blood-taking knife for slaughtering. Background Art
[0002] Animal blood is rich in nutrients and has not only medicinal value but also can be made into many favorite foods for people. The current slaughtering knives are basically traditional sharp knives. Due to the struggle of animals during slaughter, when the blood flows out from the knife cut, it is accompanied by dirt such as saliva and mucus, making it difficult to collect clean blood, and a lot of animal blood is wasted in vain. Summary of the Invention
[0003] In order to enable all the blood of slaughtered animals to be cleanly recycled, the present utility model invents a blood-taking knife for slaughtering; when slaughtering an animal with this blood-taking knife for slaughtering, without pulling out the knife, clean blood can flow from the blood inlet hole at the tip of the knife through the inner blood inlet and the knife body pipeline and then through the rear-end rubber tube into the blood collection bucket. Thus, the animal blood resources can be fully recycled.
[0004] To solve the deficiency that the existing slaughtering knives cannot recycle clean blood, the technical solution adopted is as follows: Use two stainless steel pipes with the same pipe type and appropriately sized diameters. The one with a larger diameter is made into an outer knife body with an appropriate length, and the one with a smaller diameter is made into an inner knife body; at the front end of the outer knife body, a blade tip with a blood inlet hole is welded. At the rear section of the outer knife body, there are upper and lower frame-shaped hand guards with an appropriate length. There is a space left between the frames of the upper and lower frame-shaped hand guards as the advancing and retreating channels for the lower closed hand guard and the upper open hand guard of the inner knife body. At the upper and lower parts of the rear end of the outer knife body corresponding to the advancing and retreating channels, there are notches with the same width as the advancing and retreating channels. The lower closed hand guard of the inner knife body is staggered backward by one hand guard position compared with the upper open hand guard; on both side surfaces of the lower closed hand guard and the upper open hand guard of the inner knife body at the connection with the inner knife body, there are folded edges as the sliding tracks for the inner diameter on both sides of the notch of the outer knife body, and the folded edges extend to the middle section of the inner knife body. The front end pipe orifice of the inner knife body serves as the blood inlet, and the outer wall at the blood inlet becomes a blocking body for closing the blood inlet hole of the outer knife body; behind the blocking body on the outer wall of the blood inlet of the inner knife body, there is a rubber sleeve spaced from the inner diameter of the outer knife body; the inner knife body can also be made of appropriate plastic. The rubber tube connected to the extended section at the rear end of the inner knife body is connected to the mouth cover of the blood collection bucket provided with an exhaust port. When the lower closed hand guard of the inner knife body coincides with the lower hand guard of the outer knife body, the front blocking body of the inner knife body is pushed forward in place to block the blood inlet hole of the outer knife body; when the upper open hand guard of the inner knife body coincides with the upper hand guard of the outer knife body, the inner knife body retreats in place, the blood inlet hole of the outer knife body is opened, and clean blood flows from the blood inlet hole to the blood inlet, through the inner knife body pipeline and the rear-end rubber tube into the blood collection bucket. There is a hook-shaped hanging clip on the ear handle sling of the blood collection bucket to prevent the slaughtering knife from being involved and falling, ensuring that all the clean blood is recycled.

Detailed implementation mode
[0012] In Figure 1 , two stainless steel tubes with the same tube type and appropriately sized calibers are used. The one with a large caliber is made into an outer knife body 1 with an appropriate length. In Figure 2 , the one with a small caliber is made into an inner knife body 2; in Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , a cutting edge tip 4 provided with a blood inlet hole 3 is welded at the front end of the outer knife body. In Figure 1 , Figure 3 , Figure 4 , Figure 9 , Figure 10 , Figure 11 , Figure 12In it, at the rear section of the outer knife body, there are upper and lower frame-shaped handguards 5 with appropriate lengths. In Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 In it, there is a space 6 left between the frames of the upper and lower frame-shaped handguards. In Figure 2 、 Figure 3 、 Figure 4 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 In it, as the lower closed handle guard 7 and the upper perforated handle guard 8 of the inner knife body. In Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 In it, there is an advance and retreat passage 9. In Figure 1 、 Figure 3 、 Figure 4 In it, at the upper and lower parts of the rear end 10 of the outer knife body corresponding to the advance and retreat passage. In Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 In it, there is a notch 11 with the same width as the advance and retreat passage opened for the advance and retreat passage.
[0013] The lower closed handle guard of the inner knife body is staggered backward by one handle position compared with the upper perforated handle guard; on both side surfaces of the connection between the lower closed handle guard and the upper perforated handle guard of the inner knife body, there are folded edges 12, which serve as the inner diameter sliding tracks on both sides of the notch of the outer knife body, and the folded edges extend to the middle section of the inner knife body. In Figure 2 、 Figure 3 、 Figure 4 In it, the front end pipe orifice of the inner knife body serves as the blood inlet 13, and the outer wall at the blood inlet becomes the blocking body 14 for closing the blood inlet hole of the outer knife body; behind the blocking body on the outer wall of the blood inlet of the inner knife body, there is a rubber sleeve 15 spaced from the inner diameter of the outer knife body. The rubber tube 17 connected to the extended section 16 at the rear end of the inner knife body is connected to the mouth cover of the blood receiving bucket provided with an exhaust port. When the lower closed handle guard of the inner knife body coincides with the lower handguard of the outer knife body, the front end blocking body of the inner knife body is pushed forward in place to block the blood inlet hole of the outer knife body; when the upper perforated handle guard of the inner knife body coincides with the upper handguard of the outer knife body, the inner knife body retreats in place, the blood inlet hole of the outer knife body is opened, and the clean blood flows from the blood inlet hole to the blood inlet, through the pipeline at the rear end of the inner knife body and into the blood receiving bucket through the rubber tube. There is a hook-shaped hanging clip on the ear handle sling of the blood receiving bucket, so that the slaughter knife is not involved and dropped, ensuring that all the clean blood is recycled.
