A roller is rotatably connected in the middle of the mounting seat.

[0007] Preferably, the two clamping arms and the threaded rod are symmetrically distributed, and threaded grooves are provided on the side wall of the base. The threaded grooves are symmetrically distributed and connected to the groove in sequence. The internal dimensions of the threaded grooves are adapted to the external dimensions of the threaded rod, which improves the stability of the rotation of the threaded rod.

[0008] Preferably, two limiting rods are fixed on the side wall of the clamping arm near the first connecting seat, and two sets of sliding grooves are opened on the side wall of the base near the threaded groove. The two sets of sliding grooves are symmetrically distributed to allow the limiting rods to slide, which improves the stability of the clamping arm movement.

[0009] Preferably, the base is in the shape of a truncated quadrangular pyramid, and the bottom of the base is engraved with an anti-slip groove. A support pad is fixed in the bottom of the groove, which improves the stability of the base support.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figures 1-4 A device for fixing culture flasks includes a base 1 and two clamping arms 2. The base 1 is made of plastic and is used for support and positioning. A groove 4 is provided in the middle of the base 1 for placing the culture flask. The culture flask is an important tool for in vitro culture of cells and tissues. The two clamping arms 2 are movably connected to the inner sidewalls of the groove 4 to clamp the sidewalls of the culture flask. Two threaded rods 3 are threadedly connected to the sidewalls of the base 1. A first connecting seat 5 is fixed to the inner sidewall of each clamping arm 2 near the threaded rods 3 to allow the threaded rods 3 to rotate. The other end of the threaded rod 3 is fixed by a bolt. The handle 13 is used to increase the lever arm. Both ends of the clamping arm 2 are fixed with a second connecting seat 7 by welding. The middle of the second connecting seat 7 is rotatably connected to the mounting seat 8 by a torsion spring. The middle of the mounting seat 8 is rotatably connected to the roller shaft 9. When the culture bottle is placed in the middle of the groove 4, the two clamping arms 2 are moved towards each other by rotating the handle 13, so that the clamping arms 2 are supported on the side wall of the culture bottle respectively. The roller shaft 9 cooperates with the second connecting seat 7 and the mounting seat 8, so that the four roller shafts 9 are stably attached to the side wall of the culture bottle, further improving the adaptability and stability of the clamping.

[0021] Please see Figures 1-4 The two clamping arms 2 and the threaded rod 3 are symmetrically distributed. Threaded grooves 10 are provided on the side wall of the base 1. The threaded grooves 10 are symmetrically distributed and connected to the grooves 4 in sequence. The internal dimensions of the threaded grooves 10 are adapted to the external dimensions of the threaded rod 3, which improves the stability of the rotation of the threaded rod 3. Two limiting rods 6 are fixed on the side wall of the clamping arm 2 near the first connecting seat 5. Two sets of sliding grooves 11 are provided on the side wall of the base 1 near the threaded grooves 10. The two sets of sliding grooves 11 are symmetrically distributed to allow the limiting rods 6 to slide, which improves the stability of the movement of the clamping arm 2.

[0022] Please see Figure 2 The base 1 is in the shape of a quadrangular frustum. The bottom of the base 1 is engraved with anti-slip grooves. The bottom of the groove 4 is fixed with a support pad 12, which improves the stability of the base 1.

[0023] Please see Figures 3-4All clamping arms 2 are arc-shaped, and a first protective pad 14 is fixed on the inner side wall of each clamping arm 2. A second protective pad 15 is fitted on the outer surface of each roller shaft 9. Both the first protective pad 14 and the second protective pad 15 are made of rubber and are elastic to directly contact the side wall of the culture bottle, thereby avoiding excessive pressure and damage to the culture bottle. The surfaces of the first protective pad 14 and the second protective pad 15 are engraved with anti-slip grooves to increase frictional resistance and improve the stability of the culture bottle clamping. The four mounting seats 8 are U-shaped and symmetrically distributed. The external dimensions of the mounting seats 8 are respectively adapted to the internal dimensions of the second connecting seat 7. The external dimensions of the roller shaft 9 are adapted to the internal dimensions of the mounting seats 8 in turn.

[0024] During operation, the experimenter first moves the device to the designated location and places the culture flask containing the cell culture sample in the middle of the groove 4. The support pad 12, made of rubber, supports the bottom of the culture flask, improving its stability. The culture flask is then placed between the two clamping arms 2. The experimenter rotates the two handles 13 in sequence, causing the threaded rod 3 to rotate inside the threaded groove 10. This causes the two clamping arms 2 to move towards each other and clamp the side wall of the culture flask. The mounting base 8, under the action of the torsion spring, stably clamps the four rollers 9 onto the side wall of the culture flask, thus facilitating the clamping of culture flasks of different sizes. The clamping arms 2 and rollers 9 work together to limit the clamping position, thereby improving the convenience and stability of the culture flask installation and positioning. The four limiting rods 6 are slidably connected inside the sliding groove 11 to limit the rotation of the clamping arms 2, improving the stability of the two clamping arms 2 moving towards each other. The first protective pad 14 and the second protective pad 15 are both made of rubber and are elastic, allowing them to directly contact the side wall of the culture flask, thus preventing excessive pressure from damaging the culture flask.

[0025] Through the above steps, and by setting up a base 1, clamping arms 2, threaded rod 3, first connecting seat 5, limiting rod 6, second connecting seat 7, mounting seat 8, roller shaft 9, and handle 13 according to requirements, the experimenter places the culture bottle in the middle of the groove 4, and drives the two clamping arms 2 to move towards each other by rotating the handle 13, so that the clamping arms 2 are respectively supported on the side wall of the culture bottle. The roller shaft 9 cooperates with the second connecting seat 7 and the mounting seat 8, so that the four roller shafts 9 are stably attached to the side wall of the culture bottle, further improving the adaptability and stability of clamping.
