[0030] Example 1, reference Figure 1 to Figure 3 , which is the first embodiment of the utility model, and this embodiment provides a fastening mechanism, including a clamping assembly 100, by providing a clamping member 101, an adjusting member 102 arranged outside the clamping member 101, and a limiting member 103 arranged on the outer wall of the adjusting member 102, so as to achieve the fastening effect between the connecting tube 301c and the syringe 201.

[0031] Specifically, the clamping assembly 100 includes a clamping member 101, an adjusting member 102 arranged outside the clamping member 101 and a limiting member 103 arranged on the outer wall of the adjusting member 102; the clamping member 101 includes a clamping ring 101a, a pressure plate 101a-1 is provided on the outer wall of the clamping ring 101a, a clamping block 101b is provided on the outer wall of the clamping ring 101a, and a gasket 101c is provided on the outer wall of the clamping block 101b.

[0032] Preferably, the adjusting member 102 comprises a fixing shell 102a arranged on the outer wall of the clamp ring 101a, a bolt 102b is penetrated through the outer wall of the fixing shell 102a, and a locking nut 102b-1 is arranged on the outer wall of the bolt 102b.

[0033] Preferably, a limiting plate 102c is disposed outside the locking nut 102b-1, a movable groove 102c-1 is formed on the outer wall of the limiting plate 102c, and the limiting member 103 includes a sliding rod 103a disposed on the inner wall of the fixed shell 102a.

[0034] Preferably, an elastic member 103a-1 is sleeved on the outer wall of the slide rod 103a, and a slide rail 103b is provided on the inner wall of the fixed shell 102a, and the slide rail 103b is slidably matched with the movable groove 102c-1.

[0035] Among them, the clamping ring 101a is annular as a whole, the clamping ring 101a and the pressure plate 101a-1 are an integral structure, the clamping block 101b and the clamping ring 101a are an integral structure; the limiting plate 102c is sleeved on the outer wall of the bolt 102b; the sliding rod 103a passes through the limiting plate 102c and is connected to the fixed shell 102a, and the limiting plate 102c and the sliding rod 103a are slidably matched; the sliding rail 103b and the fixed shell 102a are an integral structure; the elastic member 103a-1 is a compression spring, and the gasket 101c is made of rubber.

[0036] In summary, the syringe 201 is placed into the connecting tube 301c, and the clamping assembly 100 is further placed on the outer wall of the connecting tube 301c. The bolt 102b is rotated to adjust the distance between the pressure plates 101a-1 at both ends to a size that matches the connecting tube 301c. At the same time, the slide rail 103b and the movable groove 102c-1 are slidably matched, and the limit plate 102c slides on the outer wall of the slide rod 103a. Under the action of the elastic member 103a-1, the locking nut 102b-1 tightens the bolt 102c, so that the clamping block 101b tightens the connecting tube 301c. The gasket 101c can also play an anti-slip effect, which can solve the problem that the syringe connection is not tight and easily causes the syringe to fall off.

[0037] Example 2, reference Figure 1 , Figures 4 to 8 , which is the second embodiment of the utility model, provides a drug syringe, including an injection assembly 200. By setting a pushing assembly 300, including an auxiliary component 301, a driving component 302 arranged inside the auxiliary component 301, and a matching component 303 arranged on the outer wall of the driving component 302, uniform speed injection of the drug is achieved to avoid discomfort to the patient caused by uneven speed.

[0038] Specifically, the injection assembly 200 includes a syringe 201, a closure member 202 disposed above the syringe 201, a flow limiting valve 203 disposed below the syringe 201, a needle 204 disposed outside the flow limiting valve 203, and a protective shell 205 disposed outside the needle 204; the pushing assembly 300 includes an auxiliary member 301, a driving member 302 disposed inside the auxiliary member 301, and a matching member 303 disposed on the outer wall of the driving member 302.

[0039] Preferably, the closing member 202 comprises a top plate 202a, a through hole 202a-1 is formed on an outer wall of the top plate 202a, and a sealing ring 202b is formed on the outer wall of the top plate 202a.

[0041] Among them, the outer surface of the syringe 201 is provided with a scale, and the operator can intuitively understand the amount of medicine in the syringe 201 by simply observing the scale numbers displayed on the outer surface of the syringe 201, thereby ensuring that the dosage meets the standard requirements; when the flow rate is too fast when injecting the medicine, the flow limiting valve 203 will automatically shrink the channel, reduce the channel diameter, limit the increase in flow rate, and prevent damage to the patient's tissue due to the excessively fast injection speed; the outer sleeve of the needle 204 is provided with a protective shell 205 to prevent the needle 204 from being broken by external impact during transportation, handling and storage. At the same time, the closed structure of the protective shell 205 can also effectively block the sharp part of the needle 204 to prevent personal injury due to accidental touch; the push rod 303c extends into the syringe 201 through the through hole 202a-1, and the push rod 303c can push the push plate 201a through the pushing assembly 300 to achieve medicine injection.

[0042] In summary, by starting the motor 302b, the screw 302b-1 is driven to rotate, and the slider 302c-1 slides in the slide groove 303a-1, so that the push rod 303c moves downward, pushing the push plate 201a, and the push plate 201a pushes the medicine in the syringe 201, so that the medicine is pushed outward from the needle 204, completing the injection process.

[0043] Example 3, reference Figures 1 to 8 , which is the third embodiment of the utility model, is based on the previous embodiment, and the difference is that when the slider 302c-1 slides in the slide groove 303a-1, it drives the connecting ring 303b to slide on the outer wall of the stabilizing tube 303a, thereby driving the push rod 303c to move.

[0044] Specifically, the driving member 302 includes a stabilizing plate 302a arranged on the inner wall of the mounting tube 301b, a motor 302b is arranged above the stabilizing plate 302a, a screw 302b-1 is arranged at the output end of the motor 302b, a ring 302c is arranged on the outer wall of the screw 302b-1, and a slider 302c-1 is arranged on the outer wall of the ring 302c.

[0045] Preferably, the matching piece 303 comprises a stabilizing tube 303a disposed on the outer wall of the stabilizing plate 302a, and a slide groove 303a-1 is formed on the outer wall of the stabilizing tube 303a, and the slide groove 303a-1 is movably matched with the sliding block 302c-1.

[0046] Preferably, a connecting ring 303b is provided on the outer wall of the stabilizing cylinder 303a, a push rod 303c is provided on the inner wall of one end of the connecting ring 303b, a push plate 201a is provided inside the syringe 201, and the push rod 303c is movably matched with the push plate 201a.

[0047] Among them, the motor 302b is a forward and reverse motor; the screw 302b-1 passes through the stabilizing plate 302a and is connected to the motor 302b; the inner wall of the ring 302c is provided with a threaded hole compatible with the screw 302b-1, and the slider 302c-1 and the ring 302c are an integrated structure; the stabilizing cylinder 303a and the stabilizing plate 302a are fixedly connected; the slider 302c-1 is fixedly connected to the connecting ring 303b; one end of the connecting ring 303b is movably sleeved on the outer wall of the stabilizing cylinder 303a, and the other end is fixedly sleeved on the outer wall of the push rod 303c.

[0048] In summary, by pressing the button 301b-1, the motor 302b is started to rotate the screw 302b-1. The rotation of the screw 302b-1 causes the ring 302c to drive the slider 302c-1 to move in the slide groove 303a-1, further driving one end of the connecting ring 303b to slide on the outer wall of the stabilizing cylinder 303a. The other end of the connecting ring 303b is fixedly connected to the push rod 303c, thereby moving the push rod 303c. The push rod 303c passes through the through hole 202a-1 and pushes the push plate 201a, thereby squeezing the medicine inside the syringe 201, so that the medicine is squeezed out of the needle 204 at a uniform speed, completing the uniform injection process for the patient, and avoiding discomfort to the patient due to uneven injection speed.
