By respectively fixedly connecting the first elastic arm 300 to the second connecting portion 216 and the second elastic arm 400 to the first connecting portion 215, the first elastic arm 300 and the second elastic arm 400 have elasticity, and after the first elastic arm 300 and the second elastic arm 400 are respectively fixedly installed to the second connecting portion 216 and the first connecting portion 215, the first elastic arm 300 and the second elastic arm 400 both have a reset function when being pressed to the vertical plate due to the elasticity of the first elastic arm 300 and the second elastic arm 400. In addition, in a natural state (uncompressed state), one end of the first elastic arm 300 extending into the accommodating space is close to the first connecting portion 215, and one end of the second elastic arm 400 extending into the accommodating space is close to the second connecting portion 216, so that the rotation directions of the first elastic arm 300 and the second elastic arm 400 on one vertical plate when being pressed are opposite, and when the container 100 reaches a holding state, the first elastic arm 300 presses and clamps the container 100, and the second elastic arm 400 reversely holds and clamps the container 100.

In an embodiment of the receiving mechanism 2, the first elastic arms 300 and the second elastic arms 400 are fixed to the frame body 21 in a one-to-one correspondence. The first elastic arms 300 are installed in one-to-one correspondence with the second connection portions 216. The second elastic arms 400 are installed in one-to-one correspondence with the first connection portions 215. The second elastic arm 400 is provided with a through hole 2411, and the first elastic arm 300 passes through the through hole 2411 and then extends out to form a cross with the second elastic arm 400.

In an embodiment of the receiving mechanism 2, the first elastic arm 300 has a first engaging portion 2311 at an end extending into the receiving space, and the first engaging portion 2311 is disposed along a circumferential direction of the receiving space and is used for engaging with a sidewall of the container 100 to hold the container 100. The second elastic arm 400 is provided with a second fitting portion 2412 at one end extending into the accommodating space, the second fitting portion 2412 extends away from the first connecting portion 215 along the extending direction of the frame body 21 to form a bending portion 2413, and the bending portion 2413 is used for dragging the container 100.

In one embodiment of the receiving mechanism 2, the area enclosed by the first attaching portion 2311 is larger than the area enclosed by the second attaching portion 2412; the orthographic projection of the first attaching portion 2311 towards the second elastic arm 400 covers the through hole 2411, so that the container 100 can open the first attaching portion 2311, abut the first attaching portion 2311 against the second elastic arm 400, and open the enclosed area of the second attaching portion 2412.

In an embodiment of the receiving mechanism 2, an end of the second flexible arm 400 away from the first connecting portion 215 is bent toward the inlet end 26, so that the enclosed area of the second fitting portion 2412 is expanded and then contracted when the first fitting portion 2311 abuts against the second flexible arm 400 to open the second fitting portion 2412.

The present invention further provides an embodiment of an injection device, which is shown in fig. 1 to 13, and includes the container receiving mechanism 2 in the above embodiment, a container 100 and a pipeline, the pipeline can communicate with the container 100, and the fluid in the container 100 is injected into the body through the puncture object 200 and the pipeline.

Specifically, as shown in fig. 1-2 and 6-8, the injection device may be a CT high-pressure injector, the container 100 may be an infusion bottle, a mouth of the infusion bottle vertically extends downward into the accommodating space of the frame 21, and sequentially presses the first clamping member 231 and the second clamping member 241, so that the first clamping member 231 and the second clamping member 241 can clamp and support the container 100 under the elastic force of the torsion spring, and continuously presses the container 100, so that the mouth of the container 100 abuts against the supporting member 213 via the position limitation and the guide of the guide member 214, thereby stabilizing the container 100, and the puncture object 200 of the pipeline may extend through the space between the supporting members 213 or the hole on the supporting member 213 in advance, thereby puncturing the mouth, communicating with the reagent in the container 100, and injecting the reagent into a human body or other body. This embodiment may also be used in conjunction with the container holder comprising the first resilient arm 300 and the second resilient arm 400, and the principles are similar and will not be described in detail herein.

As shown in fig. 1-2 and 9-11, in addition, the locking mechanism 3 can ensure the stability of the medicine bottle in the frame body 21, and when the medicine bottle is replaced, the frame body 21 and the connecting seat 22 are integrally rotated to the horizontal position, so that the medicine can be prevented from polluting the injector, and the locking mechanism 3 at least consisting of the elastic member 32, the limiting member 312, the driving element 33 and the ring-shaped member 311 has a good locking effect, and is not easy to cause locking failure in a long-term use process, so that the injector can be ensured to stably operate.

The technical features of the above embodiments can be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the above embodiments are not described, but should be considered as the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
