By providing a first limit bead, the first limit bead is pushed open by one end of the first check valve when the bottom end of the insulin syringe body is clamped with the inside of the injection needle.

[0010] Preferably, the assembly component further includes: a second limit hole, which is opened on the inner bottom surface of the clamping groove. A second limit bead is clamped inside the second limit hole. A liquid medicine cavity is opened inside the insulin syringe body, and the liquid medicine cavity is communicated with the second limit hole and is also communicated with the first limit hole.

[0011] By adopting the above technical solution, by providing a second limit bead, the second limit bead and the first limit bead ensure that the liquid medicine inside the liquid medicine cavity will not overflow, keeping the internal liquid medicine in a sealed state.

[0012] Preferably, a pushing hole is opened on the top surface of the pushing tube. A second check valve is fixedly sleeved inside the pushing hole. The bottom end of the pushing tube is detachably clamped with the clamping groove.

[0013] By adopting the above technical solution, by providing a second check valve, the second check valve can make the gas inside the pushing tube flow unidirectionally towards the liquid medicine cavity, avoiding the backflow of the liquid medicine.

[0014] Preferably, a push rod is arranged inside the pushing hole. A hand push block is fixedly installed on the top surface of the push rod, and a pushing block is fixedly installed on the bottom surface of the push rod.

[0015] By adopting the above technical solution, by providing a hand push block, the hand push block facilitates the patient to manually push the push rod, improving the use comfort.

[0016] Preferably, a sealing ring is arranged inside the pushing hole. The sealing ring is in interference fit with the pushing block. The sealing ring is made of rubber, and the protection block is also made of rubber.

[0017] By adopting the above technical solution, by providing a sealing ring, the sealing ring ensures that when the push rod is pushed downward, the gas flows in one direction, avoiding the leakage of the gas.

[0018] In summary, the present invention mainly has the following beneficial effects:

[0019] By setting up the assembly components, the clamping groove can clamp the pushing tube, facilitating the assembly of the pushing tube and the insulin syringe body. When the first limit bead is clamped inside the bottom end of the insulin syringe body and the injection needle, it is pushed open by one end of the first check valve. The second limit bead and the first limit bead ensure that the liquid medicine inside the liquid medicine cavity will not overflow, keeping the internal liquid medicine in a sealed state. This not only solves the problem of the syringe taking up space during carrying but also avoids the problem of the insulin bottle being fragile.

[0020] By setting up the second check valve, the second check valve can make the gas inside the pushing tube flow unidirectionally into the liquid medicine cavity, avoiding the backflow of the liquid medicine. By setting up the sealing ring, when the push rod is pushed downward, the sealing ring ensures that the gas flows in one direction, avoiding the leakage of the gas. BRIEF DESCRIPTION OF THE DRAWINGS
