[0039] ​The fixing member 1213 is used for fixedly connecting the power source 1211, the transmission member 1212 and the transmission unit 1212.

[0040] The transmission unit 1220 comprises two symmetrically arranged pull rods 1221, one end of the pull rod 1221 is provided with a transmission structure 1223, and the pull rod 1221 is respectively provided with a driving strip 1222. The transmission unit 1220 further comprises a pressing plate 1224, which is located below the driving strip 1222 and above the clamping unit, and is used for limiting the clamping unit, so as to prevent the clamping block 1231 of the clamping unit 1230 from moving randomly in the direction of inserting and pulling the bottle. The number of the pressing plate 1224 is determined according to the data of the clamping unit 1230, and one clamping unit 1230 corresponds to a set of pressing plates 1224.

[0041] The two symmetrically arranged pull rods 1221 can move in a plane perpendicular to the direction of inserting and pulling the bottle, and the two symmetrically arranged pull rods 1221 move in opposite directions under the driving of the driving unit 1210, so as to drive the clamping block 1231 below to open and close.

[0042] The clamping unit 1230 comprises two symmetrically arranged clamping blocks 1231, and a cup 1232 is arranged between the two clamping blocks 1231. The cup 1232 is elastically stretched and contracted in the direction of inserting and pulling the bottle, and is limited and clamped with the clamping block 1231 in the direction perpendicular to the direction of inserting and pulling the bottle.

[0043] The two symmetrically arranged clamping blocks 1231 are respectively provided with a first limiting surface 12311, a second limiting surface 12312 and a third limiting surface 12313 on the opposite surfaces, which are sequentially arranged from top to bottom. The space surrounded by the first limiting surface 12311, the second limiting surface 12312 and the third limiting surface 12313 of the two symmetrically arranged clamping blocks 1231 has a diameter which increases sequentially. The first limiting surface 12311 is used for limiting the bottle, and the second limiting surface 12312 and the third limiting surface 12313 are used for limiting the cup 1232.

[0044] The clamping block 1231 further comprises a clamping groove 12314 matched with the driving strip 1222, and the driving strip 1222 can drive the clamping block 1231 to move when the driving strip 1222 moves. In an embodiment of the present application, the number of the driving strip 1222 is designed according to the number of the clamping unit 1230, and two symmetrically arranged driving strips 1222 correspond to one clamping unit 1230.

[0045] The cup 1232 is limited between the symmetrically arranged clamping blocks 1231, and the clamping blocks are provided with protrusions 12321 at both ends, which are engaged with the limiting surfaces of the clamping blocks 1231, and the protrusions 12321 are always located below the first limiting surface 12311 and can be engaged with the second limiting surface 12312 and the third limiting surface 12313, respectively. In the embodiment of the present application, grooves are arranged on the second limiting surface 12312 and the third limiting surface 12313 to better match the protrusions 12321.

[0046] The two symmetrically arranged clamping blocks 1231 are provided with first elastic members 12315 at the ends away from each other, which can respectively provide elastic force to make the two symmetrically arranged clamping blocks 1231 closer to the middle in the direction perpendicular to the insertion and extraction direction of the bottle body. Figure 6 For an embodiment of the first elastic member 12315 of the present application, the clamping block 1231 can be provided with a cavity communicating with the clamping groove 12314, and the first elastic member 12315 can be installed in the cavity, with one end abutting against the inner wall of the cavity and the other end abutting against the driving bar 1222 installed in the clamping groove 12314.

[0047] The bottom of the cup 1232, that is, the side close to the mounting frame 1100, is provided with an elastic element 1234, as shown in FIG. 7. In an embodiment of the present application, the elastic element 1234 is arranged on the protrusion 12321, but the present application is not limited thereto, and those skilled in the art should know that the elastic element 1234 can be selectively arranged on the cup 1232 according to design requirements, thereby providing elastic force in the direction of insertion of the vial.

[0048] In an embodiment of the present application, the gasket 1233 is arranged above the cup to ensure the sealing of the medicine bottle during extraction and injection, thereby avoiding corrosion and pollution of the internal structure of the clamping assembly by residual drug liquid of the syringe needle.

[0049] In an embodiment of the present application, the self-adaptive bottle body clamping device 1000 is provided with at least one friction auxiliary member 1240 between the elements with friction, which reduces the friction contact area and the friction force between the elements.

Figure 4 Figure 7A ​As shown, the separation of the clamping blocks 1231 makes the cup 1232 rise under the elastic force of the elastic member, and the cup 1232 is clamped with the second limiting surface 12312 at this time, and there is enough space in the middle of the clamping blocks 1231 for the vial to be put in. When ready to clamp, the driving bar 1222 moves to the middle, so that the first elastic member 12315 is in a compressed state.
