[0002] Injection refers to syringe A type of medical device that injects liquid or gas into the human body to diagnose, treat, or prevent disease. It is different from taking medicine. Pharmacy After injection, it can quickly reach the blood and take effect. Some surgeries require continuous adjustment of the needle position before injection to find the appropriate angle to inject the drug.

[0003] At present, the injection devices on the market have been widely used. The syringe is one of the most widely used instruments in medical institutions and the most common medical item in nursing work. The intramuscular injection of the syringe is divided into two processes. First, the needle is quickly inserted into the patient's muscle, and then the core rod is pushed to inject the drug in the syringe into the patient's body. The key to the needle is the strength and depth, which determines whether the injection treatment can deliver the drug to the designated tissue. This puts high demands on the proficiency of outpatient doctors and nurses. However, most injection devices do not have the function of adjusting the angle. Usually, some surgeries require the injection angle to be adjusted when using the injection device. The tricky injection angle will make it difficult to control the injection force.

The slot 409 corresponds to the insertion rod 412, and then the sensor 407 transmits information to the controller 6, and the controller 6 controls the indicator light 7 to light up. When the insertion rod 412 is released after the indicator light 7 lights up, the spring 414 is not affected by the pressure and then rebounds, and drives the compression block 413 to move. The movement of the compression block 413 drives the insertion rod 412 to move and insert into the slot 409 on the rotating rod 401, so that the rotating rod 401 is fixed. At this time, the needle body 301 can be fixed. The same operation is performed when adjusting the needle body 301 to other angles, so that the needle body 301 can be adjusted to an angle according to the needs of the user, and the effect of precision is achieved.

[0042] In addition, by setting the movable rod 501, when the needle body 301 needs to be replaced, the movable rod 501 is first rotated to make it rotate stably through the second bearing 503, and threadedly separated from the threaded groove 303 inside the mounting plate 302, and then moved to the inside of the adjusting plate 403, and then the needle body 301 is pulled out to separate the mounting plate 302 from the adjusting plate 403, and then a new needle body 301 is inserted into the top of the adjusting plate 403.
