[0049] The first elastic seal 3 and the second elastic seal 4 are sealed and connected to one side of the partition clamping mechanism 100 and one side of the hollow groove 2;

[0050] A second elastic seal 4, which is sealed and connected to the other side of the partition clamping mechanism 100 and the other side of the hollow groove 2;

[0051] A gas conveyor 7, wherein the gas conveyor 7 is installed at the bottom of the positioning housing 1;

[0052] A first connecting air pipe 5, two ends of which are respectively connected to the gas conveyor 7 and a cavity on one side of the positioning housing 1;

[0053] A second connecting air pipe 6, two ends of which are respectively connected to the gas conveyor 7 and the other side cavity of the positioning housing 1;

[0054] A handle 8 is fixed to one side of the positioning housing 1 .

[0055] In the embodiment of the utility model, when in use, the handle 8 is grasped, and then the positioning shell 1 is downwardly mounted along the top of the beaker so that the beaker passes through the hollow groove 2, and then the gas conveyor 7 is started to generate positive pressure in the gas conveyor 7, and the gas conveyor 7 outputs gas through the first connecting air pipe 5 and the second connecting air pipe 6. Since the two sides of the positioning shell 1 are respectively separated by two partition clamping mechanisms 100, the first elastic seal 3 and the second elastic seal 4, the partition clamping mechanism 100 is driven by air pressure to move, and the partition clamping mechanism 100 pulls the first elastic seal 3 and the second elastic seal 4 to make them tight until the partition clamping mechanism 100 clamps the beaker to complete the clamping work. The operation is simple and convenient, and beakers of different specifications can be clamped. Moreover, due to the air pressure drive, more contact surfaces can be set along the axial side of the beaker to improve the clamping stability.

[0056] In one aspect of this embodiment, the device further comprises support legs 10 and feet 9 , which can facilitate stable positioning of the height of the housing 1 .

[0057] like Figure 2 As shown, as a preferred embodiment of the utility model, the partition clamping mechanism 100 includes:

[0058] An arc-shaped elastic plate 14, both ends of which are slidably connected to the inner wall of the positioning housing 1 through a telescopic sealing plate assembly;

[0059] The roller cage assembly 200 is evenly mounted on the inner side of the arc-shaped elastic plate 14 .

[0060] In the embodiment of the utility model, when in use, gas is conveyed to the first connecting air pipe 5 and the second connecting air pipe 6 through the gas conveyor 7, and because the two sides of the positioning shell 1 are separated by two arc-shaped elastic plates 14, the first elastic seal 3 and the second elastic seal 4 respectively, the arc-shaped elastic plate 14 is driven by air pressure to move, and the arc-shaped elastic plate 14 pulls the first elastic seal 3 and the second elastic seal 4 to make them tight until the arc-shaped elastic plate 14 drives the roller retainer assembly 200 to clamp the beaker, completing the clamping work. The operation is simple and convenient, and beakers of different specifications can be clamped.

[0061] In one aspect of this embodiment, the telescopic sealing plate assembly includes:

[0064] Specifically, when the arc-shaped elastic plate 14 is driven to move by air pressure, the arc-shaped elastic plate 14 drives the sealing plate sleeve 13 and the sealing plate 12 to slide along the inner wall of the positioning shell 1 until the arc-shaped elastic plate 14 drives the roller retaining frame assembly 200 to clamp and fix the beaker. At this time, according to the different specifications of the beaker, the sealing plate sleeve 13 and the sealing plate 12 drive the two ends of the arc-shaped elastic plate 14 to continue to move until the arc of the arc-shaped elastic plate 14 is parallel to the arc of the beaker.

[0069] In one case of the present embodiment, the rotating column 16 is provided with a limit groove for the limit seat 15 to rotate. The limit seat 15 is rollingly arranged in the limit groove and partially extends outside the rotating column 16. The beaker is clamped and fixed by extending to the position outside the rotating column 16, and the friction with the beaker is reduced by rolling, and the beaker can be rotated to adjust the angle of the beaker.

[0070] like Figure 1 , Figure 3 As shown, as another preferred embodiment of the utility model, the top surface of the positioning shell 1 is provided with a heat-insulating rotating mechanism 300 for driving the beaker to rotate, and the heat-insulating rotating mechanism 300 includes:

[0078] The balls 19 are disposed inside the support plate 11 and between the bottom surface of the clamping plate 20 .

[0079] Specifically, the driving assembly drives the support plate 11 to move toward the beaker, and the support plate 11 drives the clamping plate 20 and the buffer insulation pad 21 to move until the buffer insulation pad 21 fits the outer wall of the beaker, and then the clamping plate 20 is rotated to make the clamping plate 20 roll along the ball 19 and slide along the support plate 11, so that the friction between the buffer insulation pad 21 and the beaker is used to drive the beaker to rotate and adjust the angle of the beaker.

[0080] In one aspect of this embodiment, the drive assembly includes:

[0081] A slide rail 17, wherein the slide rail 17 is fixed on the top surface of the positioning housing 1;

[0083] Specifically, the track actuator 18 adopts the existing technology and realizes the bending vibration mode by distributing the stacked piezoelectric components, thereby driving the support plate 11 to move along the slide rail 17. The track actuator 18 is not introduced in detail here, and reference is made to the existing technology.

[0084] The above embodiment of the utility model provides a beaker clamping device, which achieves the following technical effects:

[0085] When in use, the handle 8 is grasped, and the positioning shell 1 is then sleeved downwardly along the top of the beaker, so that the beaker passes through the hollow groove 2, and then the gas conveyor 7 is started to generate positive pressure, and the gas conveyor 7 outputs gas through the first connecting air pipe 5 and the second connecting air pipe 6. Since the two sides of the positioning shell 1 are separated by two arc-shaped elastic plates 14, the first elastic seal 3 and the second elastic seal 4 respectively, when the arc-shaped elastic plate 14 is driven by air pressure to move, the arc-shaped elastic plate 14 drives the sealing plate sleeve 13 and the sealing plate 12 to slide along the inner wall of the positioning shell 1 until the arc-shaped elastic plate 14 drives the roller retainer assembly 200 to clamp and fix the beaker. At this time, according to the beakers of different specifications, the sealing plate sleeve 13 and the sealing plate 1 2 drives both ends of the arc-shaped elastic plate 14 to continue to move until the arc of the arc-shaped elastic plate 14 is parallel to the arc of the beaker and fixed, and then the track actuator 18 drives the support plate 11 to move along the slide rail 17, and the support plate 11 drives the clamping plate 20 and the buffer insulation pad 21 to move until the buffer insulation pad 21 fits the outer wall of the beaker, and then the clamping plate 20 is rotated to make the clamping plate 20 roll along the ball 19 and slide along the support plate 11, so that the friction between the buffer insulation pad 21 and the beaker is used to drive the beaker to rotate and adjust the angle of the beaker. The operation is simple and convenient, and beakers of different specifications can be clamped. Moreover, due to the air pressure drive, more contact surfaces can be set along the axial side of the beaker to improve the clamping stability.
