A circular hole is provided on the surface of the connecting tube 402, and a fixing column 406 is clamped on the inner wall of the circular hole. A fixing rubber pad 405 is fixedly connected to the surface of the fixing column 406. A fixing hole 407 is provided on the surface of the fixing column 406, and a fixing rod 408 is slidably inserted in the fixing hole 407. A fixing spring 409 and a spring rod 410 are fixedly connected to the bottom of the fixing rod 408, and an adjusting rod is fixedly connected to the surface of the fixing rod 408. A fixing spring 409 and a spring rod 410 are fixedly connected to the surface of the groove 401, and a fixing spring 409 is sleeved on the surface of the spring rod 410. By setting the protective structure 4, when using the utility model, in order to avoid the injection head 3 of most syringes being fixedly installed on the front end of the needle tube 1, when the syringe is carried, the injection head 3 is placed in the medicine box. Due to the protruding part, it is easy to shake during transportation and carrying, which can easily cause the injection head 3 to collide, deform and break. The position of the protective structure 4 can be adjusted. When it is needed, the plastic sticker 411 is first torn off, and the adjustment rod is moved in the direction away from the fixing hole 407 to drive the fixing rod 408 to move out of the fixing hole 407, and then the fixing rubber pad 405 is moved along the fixing hole 407. The fixing column 406 is clamped in the circular hole opened on the surface of the connecting tube 402. At this time, the adjusting rod is loosened, and the bottom fixing spring 409 drives the spring rod 410 to squeeze the fixing rod 408 so that it is clamped in the fixing hole 407, thereby achieving the effect of fixing the fixing rubber pad 405. Finally, the injection head 3 is clamped along the groove 401 opened on the surface of the needle tube 1. Since the internal fixing rubber pad 405 is elastic, it is easy to achieve the effect of installing and fixing the injection head 3. After use, the needle can be removed, and then the plastic sticker 411 is attached to the surface of the groove 401 to achieve a sealing effect, which is convenient for carrying.

The piston rod 2 is slidably connected in the notch 604. A rubber clamp 606 is fixedly connected to one end of the sealing sleeve 601 close to the connecting sleeve 602. A clamping groove 605 is provided on one end of the connecting sleeve 602 close to the sealing sleeve 601. The inner wall of the clamping groove 605 is clamped with a rubber clamp 606. By providing the sealing structure 6, when using the utility model, in order to prevent the piston rod 2 inside the needle tube 1 from directly contacting the air when it moves out, which poses a potential safety hazard, the sealing structure 6 can be used for sealing, so that the sealing sleeve 601 and the connecting sleeve 602 are clamped on the surface of the needle tube 1. At this time, the sealing rubber ring 603 on the inner wall of the connecting sleeve 602 is convenient for achieving a sealing effect, and at the same time, the rubber clamping block 606 along the surface of the sealing sleeve 601 is clamped in the notch 604 opened on the surface of the connecting sleeve 602 to achieve a sealing effect.

Working principle: when using the portable syringe, when it is needed, the injection head 3 can be installed on the surface of the needle tube 1 first, and then the piston rod 2 can be pulled to achieve the effect of inhaling and injecting liquid and air. After use, in order to avoid the injection head 3 of most syringes being fixedly installed at the front end of the needle tube 1, when carrying the syringe, the injection head 3 is placed in the medicine box. Since the protruding part is prone to shaking during transportation and carrying, it is easy to cause the injection head 3 to collide, deform and break. The position of the protective structure 4 can be adjusted to install the injection head 3 inside the needle tube 1 to achieve the protection effect. When it is needed, the plastic sticker 411 is first torn off, and the adjustment rod is moved in the direction away from the fixing hole 407 to drive the fixing rod 408 to move out of the fixing hole 407, and then the fixing rubber pad 405 is clamped in the round hole opened on the surface of the connecting tube 402 along the fixing column 406. At this time, the adjusting rod is loosened, and the bottom fixing spring 40 9 drives the spring rod 410 to squeeze the fixing rod 408 to make it snap into the fixing hole 407, thereby achieving the effect of fixing the fixing rubber pad 405, and finally the injection head 3 is snapped into the groove 401 opened on the surface of the needle tube 1. Since the internal fixing rubber pad 405 is elastic, it is convenient to achieve the effect of installing and fixing the injection head 3. After use, the needle can be removed, and then the plastic sticker 411 is attached to the surface of the groove 401 to achieve a sealing effect, which is convenient for carrying. At the same time, in order to avoid the piston rod 2 inside the needle tube 1 directly contacting the air when it is moved out, there is a safety hazard problem, the sealing structure 6 can be used for sealing, so that the sealing sleeve 601 and the connecting sleeve 602 are snapped into the surface of the needle tube 1. At this time, the sealing rubber ring 603 on the inner wall of the connecting sleeve 602 is convenient to achieve a sealing effect. At the same time, the rubber block 606 along the surface of the sealing sleeve 601 is snapped into the notch 604 opened on the surface of the connecting sleeve 602 to achieve a sealing effect, thereby completing the entire use.
