DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0021] Please refer to Figures 1-4 In the present embodiment: a constant-temperature mixing instrument, comprising a mixing instrument device and a placement frame 3 arranged on the mixing instrument device, a plurality of through holes 4 are arranged on the placement frame 3, and a limiting device is arranged in each through hole 4.

[0022] The limiting device comprises a limiting frame one 11, a limiting frame two 10, and two guide plates 6. The limiting frame one 11 and the limiting frame two 10 are oppositely arranged. The cross sections of the limiting frame one 11 and the limiting frame two 10 are both arranged in a semicircular ring shape. The upper end edges of the limiting frame one 11 and the limiting frame two 10 are both arranged in an arc shape. The opposite sides of the limiting frame two 10 are provided with a connecting groove 14 through which the limiting frame one 11 passes. The two guide plates 6 are fixedly arranged at the upper ends of the limiting frame one 11 and the limiting frame two 10, respectively. The two guide plates 6 are oppositely and obliquely arranged. The bottoms of the limiting frame one 11 and the limiting frame two 10 are fixedly connected with connecting plates 12, respectively. The two connecting plates 12 are movably arranged in two movable grooves 8 provided in the bottom wall of the through hole 4. The opposite sides of the two connecting plates 12 are both fixedly connected with elastic members. The ends of the two elastic members away from the two connecting plates 12 are both fixedly connected with the inner sides of the two movable grooves 8, respectively. The elastic members are springs 13. One end of the spring 13 is fixedly connected with one side of the connecting plate 12. The end of the spring 13 away from the connecting plate 12 is fixedly connected with the inner side of the movable groove 8.

[0023] Specifically, by arranging the limiting frame one 11 and the limiting frame two 10, when a reagent tube with a smaller pipe diameter needs to be fixed during use, the reagent tube with a smaller pipe diameter will first contact the two guide plates 6 during the process of entering the through hole 4. The two guide plates 6 are oppositely and obliquely arranged, so that the bottom of the reagent tube with a smaller pipe diameter will move to the middle position of the two guide plates 6, i.e., the middle position of the limiting frame one 11 and the limiting frame two 10. During this process, the reagent tube with a smaller pipe diameter will push the limiting frame one 11 and the limiting frame two 10, so that the limiting frame one 11 and the limiting frame two 10 will move in opposite directions, driving the two connecting plates 12 to move. The movement of the two connecting plates 12 will press the two springs 13, respectively, until the reagent tube with a smaller pipe diameter completely enters between the limiting frame one 11 and the limiting frame two 10. At this time, the pushing force of the two springs 13 can make the limiting frame one 11 and the limiting frame two 10 adhere to the opposite sides of the reagent tube with a smaller pipe diameter, realizing the limiting and fixing of the reagent tube with a smaller pipe diameter, so that the overall equipment has higher universality and can also realize the fixing of the reagent tube with a smaller pipe diameter.

[0024] The opposite inner side walls of the through hole 4 are both provided with mounting grooves 7 through which the two guide plates 6 enter. The arrangement of the two mounting grooves 7 at this position makes it possible for the two guide plates 6 to move normally without movement conflict during the movement of the two guide plates 6.

[0025] The heating element 9 is installed on the adjacent side of the limiting frame one 11 and the limiting frame two 10, and the heating element 9 is a heating wire, which ensures the constant temperature effect of the reagent tube; the mixing instrument device comprises a mixing instrument body 1 and a mounting frame 2, the mounting frame 2 is fixedly arranged on the mixing instrument body 1, a placing frame 3 is fixedly arranged in the mounting frame 2, a plurality of heat dissipation holes 5 are arranged on one side of the mixing instrument body 1, and the heat dissipation holes 5 are arranged to volatilize the heat generated during the operation of the equipment;

[0026] The mixing instrument body 1 is a constant-temperature mixing instrument TCS10.

[0027] The working principle and use process of the device are as follows: when the device is used, when it is necessary to fix the reagent tube with a smaller pipe diameter, the bottom of the reagent tube with a smaller pipe diameter will first contact the two guide plates 6 during the process of entering the through hole 4, the two guide plates 6 are arranged in opposite inclined modes, so that the bottom of the reagent tube with a smaller pipe diameter will move to the middle position of the two guide plates 6, that is, the middle position of the limiting frame one 11 and the limiting frame two 10, and in the process, the reagent tube with a smaller pipe diameter will push the limiting frame one 11 and the limiting frame two 10, so that the limiting frame one 11 and the limiting frame two 10 will move in opposite directions, so that the two connecting plates 12 will be driven to move, the movement of the two connecting plates 12 will respectively extrude the two springs 13, until the reagent tube with a smaller pipe diameter completely enters between the limiting frame one 11 and the limiting frame two 10, at this time, the limiting frame one 11 and the limiting frame two 10 can be attached to the opposite sides of the reagent tube with a smaller pipe diameter through the pushing force of the two springs 13, so as to realize the limiting and fixing of the reagent tube with a smaller pipe diameter, so that the overall equipment has higher universality, and the reagent tube with a smaller pipe diameter can also be fixed.
