The first clamping arm 220 has an open state in which the two second ends 222 are away from each other and a closed state in which the two second ends 222 are close to each other. When the first clamp arm 220 is in the open state, the notch of the receiving groove 211 is open. When the first clamp arm 220 is in the closed state, the notch portion of the accommodation groove 211 is shielded by the first clamp arm 220. The first clamping assembly 200 is used to clamp a first end 910 of a disposable bio-bag 900. When the disposable bio-bag 900 is clamped, the first clamp arm 220 is rotated so that the first clamp arm 220 is opened, then the first end 910 is installed in the accommodating groove 211, and then the first clamp arm 220 is reversely rotated so that the first clamp arm 220 is closed. Since the notch portion of the receiving groove 211 is blocked by the first clamping arm 220 when the first clamping arm 220 is in the closed state, the first clamping arm 220 can be clamped into the first groove 911 of the first end 910 of the disposable bio-bag 900, so that the first end 910 of the disposable bio-bag 900 can be clamped by the first clamping assembly 200.

Further, the first clamping arms 220 are substantially arc-shaped, and a pair of the first clamping arms 220 are disposed around the circumference of the accommodating groove 211. Thus, when the first clamping arm 220 is in the closed state, the first clamping arm 220 has a larger contact area with the first end 910, so that the first end 910 can be firmly fixed.

The first clamping assembly 200 further includes a first elastic member 230, where the first elastic member 230 connects the first clamping arm 220 and the base 210, and the first elastic member 230 is configured to apply a force to the first clamping arm 220 that rotates toward the closed state. In this way, the first clamping arm 220 can firmly clamp the first end 910 of the disposable bio-bag 900 under the elastic force of the first elastic member 230, thereby firmly fixing the disposable bio-bag 900. Moreover, when the first end 910 of the disposable biological bag 900 is clamped, the first clamping arm 220 can be opened by manually rotating the first clamping arm 220, after the first clamping arm 220 is released, the first clamping arm 220 can be automatically folded into a folded state and clamp the first end 910 under the elastic force of the first elastic member 230, so that the disposable biological bag is very convenient to use, the first clamping arm 220 does not need to be reversely rotated manually, and the first clamping arm 220 does not need to be locked in the folded state by arranging a locking structure.

Further, the first elastic member 230 is a ball screw or a spring, and the spring may be a compression spring, an extension spring or a torsion spring, but is not limited thereto, and in other embodiments, the first elastic member 230 may be a elastic cord, etc., as long as the first elastic member 230 can apply a force to the first clamping arm 220 to rotate toward the closed state.

Therefore, the connection between the base 210 and the first clamping arm 220 is compact, the ball screw can provide better elastic force, and the ball screw is hidden in the first connecting hole 224, which is beneficial to keeping the appearance beautiful.

The base 210 is provided with a first limiting post 240, and the first limiting post 240 is disposed on a side of the first clamping arm 220 away from the accommodating groove 211, so as to limit a rotation range of the first clamping arm 220 in a direction away from the accommodating groove 211. The first limiting post 240 can limit the rotation range of the first clamping arm 220, so as to prevent the first clamping arm 220 from being opened by an excessive angle, thereby reducing the excessive stretching of the first elastic member 230 and further reducing the loss of the first elastic member 230.

The first limiting post 240 is disposed near the first end 221 of the first clamping arm 220, and the first clamping arm 220 is provided with a limiting groove 223 corresponding to the first limiting post 240. When the first clamping arm 220 is in the open state, the first limiting post 240 abuts against the bottom wall of the limiting groove 223. In this way, the structure is more compact.

The first clamping assembly 200 further includes a cover plate 250, the cover plate 250 is fixedly connected to one side of the base 210 where the first clamping arm 220 is disposed, and the first clamping arm 220 is located between the cover plate 250 and the base 210, and the cover plate 250 is provided with a receiving hole 251 corresponding to the receiving groove 211. The cover plate 250 and the base 210 cooperate to limit the movement range of the first clamping arm 220, so that the first clamping arm 220 is more firmly mounted on the base 210, and thus the first clamping arm 220 is not easy to fall off from one side of the base 210. In addition, the cover plate 250 can also cover the first clamping arm 220, so that the first clamping assembly 200 is more attractive in appearance.

The second end 222 of the first arm 220 is provided with a first handle 260 for holding, and the first handle 260 protrudes from the side wall of the base 210, so that a user can push the first arm 220 to rotate through the first handle 260. The first handle 260 also protrudes from the sidewall of the cover plate 250. In one embodiment, the first handle 260 is in a straight rod shape, which is convenient to hold.

The first clamping assembly 200 further includes a first connecting shaft 270, where the first connecting shaft 270 sequentially penetrates through the cover plate 250, the first end 221 of the first clamping arm 220, and the base 210, so that the cover plate 250 is fixedly connected to the base 210 through the first connecting shaft 270, and the first clamping arm 220 is rotatably connected to the base 210 through the first connecting shaft 270. In this way, the first connecting shaft 270 functions as both the connecting cover plate 250 and the base 210 and the rotating shaft of the first clamping arm 220, simplifying the structure and making the first clamping assembly 200 more compact.

The first clamping assembly 200 further includes a second connecting shaft 280, the second connecting shaft 280 fixedly connecting the cover plate 250 to the base 210.

In this way, the first connection post 290 can rotate within the first connection sleeve 292, so that the first connection post 290 is rotatably connected to the first frame 110 through the first connection sleeve 292. In an embodiment, the first stopping end 291 may be a screw screwed to the first connecting post 290, and the head of the screw may stop at one end of the first connecting sleeve 292, so as to prevent the first connecting post 290 from falling off. In this embodiment, the first connecting post 290 is movable in the axial direction of the first connecting sleeve 292. When the bracket 100 is rotated, the first connection column 290 may automatically drop down due to gravity. The base 210 and the first stop end 291 can be respectively stopped at the end of the first connecting sleeve 292, so as to limit the axial movement range of the first connecting column 290 along the first connecting sleeve 292 and prevent the first connecting column 290 from falling off from the first connecting sleeve 292.
