The limiting plate 4 can break away from or lean on the cradling piece 5 according to the mode that the extension piece 3 rotated around the axis of axle 6. Under the condition that limiting plate 4 leans on to cradling piece 5, the axial of injection cylinder 2 is perpendicular with the terminal surface of chassis 13. As shown in fig. 1, in particular, when the medical staff performs the injection operation for the patient, the injection angle can be changed by adding a support in the area between the limiting plate 4 and the support rod 5, and the preferred injection angle is 90 degrees.

Preferably, the side of the fixing sleeve 8 is provided with a groove 17 in a through-going manner. The side of the fixing sleeve 8 is provided with an indicator plate 9 in an integrally formed manner. The first side of the indicator panel 9 is provided with a plurality of graduation marks 15. The side of the injection tube 2 is provided with a pointer 16, the pointer 16 can intuitively reflect the depth of the needle head 12 inserted into the skin of the patient by matching with the scale marks 15, and the waste of the medicine caused by poor penetration depth can be avoided. The syringe 2 is nested in the fixed sleeve 8 in a manner that the pointer 16 can slide in the groove 17, and the groove 17 enables the pointer 16 to keep a certain distance from the scale marks 15 in the circumferential direction of the fixed sleeve 8, so that the position of the pointer 16 can be prevented from deviating in the circumferential direction during the skin penetrating process of a patient, and the accurate judgment of the injection depth can be prevented from being influenced. In case the injection assembly is subjected to an external force, the distance between the pointer 16 and the first end of the groove 17 from each other can be increased or decreased in such a way that the syringe 2 slides in the stationary sleeve 8. And the distance between the pointer 16 and any one of the several graduation marks 15 can be increased or decreased in such a way that the syringe 2 slides in the fixed sleeve 8. As shown in fig. 1, when the medical staff injects the medicine into the patient, the angle of the fixed sleeve 8 is determined first, then the injection assembly is inserted into the fixed sleeve 8 and pushed along the axial direction of the fixed sleeve 8 to make the needle 12 abut against the epidermis of the patient, next the graduation mark 15 pointed specifically by the pointer 16 is observed, then the injection assembly is pushed continuously to make the needle 12 penetrate into the epidermis of the patient, and in the process, the medical staff observes the distance between the graduation mark 15 pointed finally by the pointer 16 and the starting graduation mark 15 to judge the depth of the needle 12 penetrating into the tissue of the patient. Preferably, the graduation marks 15 are equally spaced. Distance values are correspondingly marked at the scale lines 15 on the indicating plate 9, so that medical staff can conveniently observe and judge the injection depth. Preferably, the second end face of the chassis 13 is provided with a gasket 11 in an adhesive connection, wherein: the gasket 11 is annular. The liner 11 is mounted coaxially with the chassis 13 and the liner 11 has an inner diameter smaller than that of the chassis 13. Preferably, the pad 11 may be a rubber sheet having elasticity. The cushion 11 can add comfort to the patient when the chassis 13 is secured.

Preferably, the pad 11 is connected to at least two jaws 14 by means of a connecting web 18 having elasticity. For example, two splints 14 may be symmetrically arranged to lift the patient's skin during injection, or four splints 14 may be provided, two of which are used to lift the patient's skin and the other two are ready for use. As shown in fig. 1, the number of the clamping plates 14 may be preferably two. The clamping plates 14 are symmetrically distributed on both sides of the injection tube 2, wherein: a first end of the connecting piece 18 is connected to a first side of the clamping plate 14. The second end of the connecting piece 18 is connected to the inner side face of the pad 11. The first end surface of the splint 14 is provided with a magic tape 19 for adhering the skin of the patient. In the case where the clamping plates 14 are subjected to an external force, the distance between the clamping plates 14 can be reduced in such a manner that the connecting pieces 18 are extended. As shown in fig. 4, the connecting piece 18 may preferably be an elastic rubber piece. Preferably, the magic tape 19 may be a double-sided tape. When medical staff injects medicine to a patient, the skin of the patient at the area to be injected can be pulled to be raised by pulling the two clamping plates 14 opposite to each other, and the magic tape 19 moves along with the two clamping plates 14, and the skin of the patient is pulled under the action of the magic tape 19. Can effectively restore the process that medical staff lifts the skin by using the thumb, the index finger and the middle finger when injecting, and is convenient for medicine injection.

Preferably, at least two straps 10 for fixing the chassis 13 are arranged on the side of the chassis 13, the number of the straps 10 can be two symmetrically distributed or four or more, and the straps 10 are used for fixing. For example, when two restraining straps 10 are provided, they are tied to one another to secure the device to the skin of the patient. When four binding bands 10 are provided, the device is fixed on the skin of the patient in a manner of being bound two by two, so that the stability is better. As shown in fig. 1, it is preferable that the number of the restraining strip 10 may be two. The two binding belts 10 are symmetrically distributed on two sides of the injection tube 2. Preferably, the restraining strip 10 may be a medical elastic bandage for securing the chassis 13 to the body of a patient.

Preferably, the fastening element 7 is mounted through and screwed to the side of the fixing sleeve 8, wherein: the fastener 7 can be brought into abutment against or disengaged from the syringe 2 in such a way as to rotate about its central axis. Preferably, the fastener 7 may be a screw. In order to prevent the injection assembly from sliding in the fixing sleeve 8 when the medical staff presses the push rod 1 to inject, so as to change the injection depth, after the needle 12 penetrates into the patient and reaches the target depth, the fastening member 7 is screwed to abut against the injection cylinder 2, the position of the injection cylinder 2 in the fixing sleeve 8 is locked, and then the push rod 1 is pressed to inject, so that the penetration depth of the needle 12 into the patient can be kept unchanged during the injection process.

For easy understanding, the working principle of the syringe for endocrinology of the present invention will be discussed.

When a medical staff member injects medicine into a patient, firstly, the base plate 13 is fixed at a target injection area through the binding belt 10, then the fixing sleeve 8 is fixed at an angle through a mode of adding a support between the limiting plate 4 and the bracket rod 5, the skin of the area to be injected of the patient is tensioned and raised through pulling the two clamping plates 14 opposite to each other, then the injection assembly is embedded into the fixing sleeve 8 and is pushed along the axial direction of the fixing sleeve 8 so that the needle 12 is abutted to the raised skin of the patient, then the scale line 15 specifically pointed by the pointer 16 is observed, then the injection assembly is pushed continuously so that the needle 12 penetrates into the skin of the patient, in the process, the medical staff member observes the distance between the scale line 15 finally pointed by the pointer 16 and the initial scale line 15 so as to judge the depth of the needle 12 penetrating into the tissue of the patient, and after the needle 12 penetrates into the body of the patient and reaches the target depth, the fastener 7 is screwed to abut against the injection cylinder 2, and then the push rod 1 is pressed to perform injection.
