The syringe consists of a syringe with a small hole at the front end and a matching piston core rod. It is used to inject a small amount of liquid or gas into or extract it from areas that are inaccessible by other methods. When the core rod is pulled out, the liquid or gas is sucked from the small hole at the front end of the syringe, and the liquid or gas is squeezed out when the core rod is pushed in. The prior art discloses a disposable sterile syringe that is easy to recycle, application number: CN202123194496.5, in order to solve the problem that the syringe is disposable The syringe can still be used after being used once, so some lawless elements will recycle and clean the used syringes and then sell them back on the market, which can easily cause cross infection. The rubber plug and the block are completely locked together by the locking assembly, making the syringe unusable. When the clamping assembly is opened again, the needle in the injection assembly will be pulled into the syringe and cannot be pulled out, further destroying the syringe and making it completely unusable. However, the above structure uses too many auxiliary structures and is integrated with the syringe, resulting in a high production cost of the syringe, and the auxiliary structure is scrapped together with the injection tube, and the economy of use is poor.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] This specific embodiment is a disposable sterile syringe that is easy to recycle, and its structural schematic diagram is as follows Figure 1As shown, it includes an injection tube 1, a tube handle 2, a plug rod 3 and a crushing mechanism 4. The tube handle 2 is arranged at one end of the injection tube 1 and closes the end opening of the injection tube 1. The plug rod 3 penetrates into the injection tube 1 along the tube handle 2. The tube handle 2 has a sliding hole for the plug rod 3 to slide through. The crushing mechanism 4 is detachably mounted on the tube handle 2. Figure 3 One end of the stopper rod 3 that penetrates into the injection tube 1 is fixedly connected to a plug head 10 , and the plug head 10 is blocked and limited in the injection tube 1 by the tube handle 2 .

[0024] Reference Figure 3 A cutoff line 9 is provided on the outer wall of one end of the plug rod 3 close to the plug head 10. Pushing the pressing head 5 toward the plug rod 3, the blade 6 can be forced to move toward the cutoff line 9 until the blade 6 completely passes through the plug rod 3 to cut off the plug rod 3.

[0025] Reference Figure 2 , Figure 4 The crushing mechanism 4 includes a fixed plate 8, a blade 6, and a pressing head 5. The fixed plate 8 fits the outer wall of the pipe handle 2, and a fixed block 12 is fixedly installed on the side of the fixed plate 8 facing the plug rod 3. The blade 6 is embedded in the fixed block 12 and slides toward the plug rod 3. Clamping rods 7 are respectively provided on the outer walls on both sides of the fixed plate 8. The clamping rod 7 is an L-shaped structure, and a chuck 11 is fixedly connected to the end away from the fixed plate 8. The chuck 11 is made of rubber, and the end away from the clamping rod 7 is close to the outer wall of the pipe handle 2. The interior of the fixed block 12 is a hollow structure, and the blade 6 slides vertically along the interior of the fixed block 12 and slides out from the bottom end surface of the fixed block 12. The upper surface of the fixed block 12 has a through hole, and the pressing head 5 slides through the through hole to connect with the blade 6. The cut-off part of the stopper rod 3 is discarded, and the remaining part of the stopper rod 3 and the plug head 10 are retained in the injection tube 1. Since the handle 2 closes the end of the injection tube 1, the plug head 10 can no longer be used, thereby avoiding the secondary use of the injection tube 1.

[0026] Working principle: When in use, the plug 10 is pulled by the plug rod 3, so that the plug 10 can inhale and squeeze out the liquid medicine in the syringe 1. The injection principle of the syringe 1 is consistent with the prior art. When the syringe 1 is used up, it can be immediately destroyed for recycling. At this time, the crushing mechanism 4 is installed on the tube handle 2, and the fixing plate 8 is fixed to the tube handle 2 by the clamping rod 7. The clamp 11 fits with the outer wall of the tube handle 2 to clamp the fixing plate 8, and then the plug rod 3 is stretched to gradually bring the plug 10 closer to the tube handle 2 until the cut-off line 9 is exposed between the syringe 1 and the tube handle 2. The blade 6 is flush, and the pressing head 5 is pushed toward the stopper rod 3. The blade 6 can be forced to move toward the cutoff line 9 until the blade 6 completely passes through the stopper rod 3 to cut off the stopper rod 3, and the cutoff part of the stopper rod 3 is discarded. At this time, the remaining part of the stopper rod 3 and the plug head 10 are retained in the injection tube 1. Since the tube handle 2 closes the end of the injection tube 1, the plug head 10 can no longer be used, which can avoid the secondary use of the injection tube 1. Then the fixing plate 8 can be removed from the tube handle 2 and replaced with a new injection tube 1 for use.
