[0029] The base plate 11 serves as the base component of the whole tooling, for bearing the hydrogel sample and other related components, the connecting shafts 12 provide the rotating shafts for the rotating columns 13, so that the rotating columns 13 can rotate under the action, by adjusting the state of the rotating columns 13, i.e. vertical or horizontal state, the operation of putting in and taking out the hydrogel is realized, the guide columns 14 can quickly restrict the top plate 15 on the top of the rotating column 13, and the top plate 15 is used for restricting the hydrogel inside the rotating column 13;

[0030] The outer surfaces of the two sides of the top plate 15 are fixed with fixed plates 16, the outer surface of the rotating column 13 is fixed with a support plate 18, the lower surface of the fixed plate 16 is fixed with a connecting column 17, and the connecting column 17 penetrates through the inside of the support plate 18;

[0031] The fixed plate 16 is used for bearing and installing the connecting column 17, and the connecting column 17 is used for connecting the fixed plate 16 and the support plate 18, so as to restrict the top plate 15 at the required position;

[0032] The inside of the connecting column 17 and the support plate 18 is screw-connected with a threaded column 19, and the outer surface of the threaded column 19 is fixed with a guide plate 191;

[0033] The threaded column 19 is used for fixing the connecting column 17 inside the support plate 18, and the guide plate 191 is used for conveniently exerting the rotating force on the threaded column 19.

[0034] Working principle: when the freeze resistance of the hydrogel needs to be detected, the hydrogel is first put into the inside of the base plate 11, under the action of the connecting shafts 12, the rotating force is exerted on the rotating column 13, so that the rotating column 13 is in the vertical state, then the top plate 15 is passed through the guide column 14 under the guidance of the guide column 14, so that the top plate 15 is in abutment with the surface of the rotating column 13, at the same time, the connecting column 17 penetrates through the inside of the support plate 18, then the rotating force is exerted on the guide plate 191, so as to drive the threaded column 19 to penetrate through the inside of the connecting column 17, after the hydrogel is restricted inside the rotating column 13, the hydrogel sample is taken out after being soaked in different low-temperature conditions for a certain time, by the above-mentioned way, the top plate 15 is taken off from the top of the rotating column 13, and the rotating column 13 is adjusted to be in the horizontal state, then the hydrogel is taken off from the base plate 11, the surface water is absorbed by filter paper, the mass is weighed, the swelling degree or water absorption rate is calculated, and the data at normal temperature is compared;

[0035] This step, simple and perfect, moves the hydrogel to the desired position, and then facilitates the test of the hydrogel.

[0036] Please refer to Figures 1-4 As shown in the drawings, the embodiment is based on the above-mentioned embodiment, further comprising a limiting assembly, the limiting assembly comprising a fixed frame 21, a connecting frame 22, a connecting rod 23 and a fixed tube 24; the fixed frame 21 is fixed on the outer surface of the rotating column 13, the connecting frame 22 is fixed on the upper surface of the bottom plate 11, the connecting rod 23 is clamped inside the fixed frame 21 and the connecting frame 22, and the fixed tube 24 is fixed on the outer surface of the connecting frame 22.

[0037] The fixed frame 21 is used in cooperation with the connecting frame 22 to provide a space for the connecting rod 23 to insert and position, ensuring that the connecting rod 23 can be accurately inserted into the fixed frame 21 and the connecting frame 22, thereby realizing the limitation of the state of the rotating column 13; the fixed tube 24 is used to install the spring 25;

[0038] The fixed tube 24 is fixed with a spring 25 inside, the spring 25 is fixed with a fixed column 26 on the outer surface, and the fixed column 26 is fixed with a connecting plate 28 on the outer surface;

[0039] The spring 25 is used to provide a spring force, when the connecting plate 28 is not under tension, the spring force of the spring 25 can push the fixed column 26 and the connecting plate 28 to reset, so that the limiting rod 29 passes through the inside of the connecting rod 23, realizing the quick switching and fixing of the state of the rotating column 13;

[0040] The connecting plate 28 is fixed with a sealing ring 27 on the surface, the sealing ring 27 is clamped inside the fixed tube 24, the connecting plate 28 is fixed with a limiting rod 29 on the surface, and the limiting rod 29 is connected to the inside of the connecting rod 23:

[0041] The sealing ring 27 plays a sealing role to prevent foreign matter from entering the inside of the fixed tube 24 and affecting the normal work of the spring 25, and the limiting rod 29 is used to insert into the inside of the connecting rod 23, thereby completing the locking of the vertical state of the rotating column 13.

[0042] Working principle: when it is needed to adjust the rotating column 13 to the vertical state, after adjusting two groups of rotating columns 13 to the vertical state, a pulling force is applied to the connecting plate 28, the fixed column 26 is moved out of the inside of the fixed tube 24, the connecting rod 23 is inserted into the inside of the fixed frame 21 and the connecting frame 22, the force applied to the connecting plate 28 is cancelled, under the action of the spring force of the spring 25, the limiting rod 29 passes through the inside of the connecting rod 23, then a pressing force is applied to the connecting plate 28, so that the sealing ring 27 is inserted into the inside of the fixed tube 24;
