[0029] In addition, the bidirectional screw 73 can connect the first clamping plate 75 and the second clamping plate 76, and the limiting rod 74 can limit the first clamping plate 75 and the second clamping plate 76, so that when the bidirectional screw 73 is rotated, it can smoothly drive the first clamping plate 75 and the second clamping plate 76 to move in opposite directions.

The setting of the connecting block 111 can facilitate the staff to add water to the interior of the constant temperature mechanism 6, and the setting of the closing cover 112 can close 11, thereby reducing the situation where the heat inside the water tank 67 flows out in large quantities through the connecting block 111.

[0034] See also Figure 1-4: The upper sides of the first insulating hollow block 61 and the second insulating hollow block 62 are both connected with an insulating plate 10. The two insulating plates 10 are both arranged on the outside of the detection tube body 3. The insulating plate 10 can play a certain shielding role on the upper side of the liquid cup 5, thereby reducing the temperature of the liquid inside the liquid cup 5 from being lost in large quantities through the upper side of the liquid cup 5.

[0035] See also Figure 1 and Figure 2 : One end of the bidirectional screw 73 is connected to an extension rod 12, and one end of the extension rod 12 passes through the first fixed block 71. The extension rod 12 is used to facilitate the rotation of the bidirectional screw 73. The bidirectional screw 73 can effectively install and fix the extension rod 12. The setting of the extension rod 12 makes it more convenient, simple and easy for the staff to rotate the bidirectional screw 73 when they need to.

[0037] Working principle: When the utility model is used, the staff can inject water into the water tank 67, and after the injection, the water inside the water tank 67 is heated by the operation of the heating plate 692. While heating, the staff can observe the temperature displayed by the temperature display 681. When the required temperature is reached, the staff can start the pump body 65 to allow the water inside the water tank 67 to smoothly flow into the first heat-insulating hollow block 61 and the second heat-insulating hollow block 62. At this time, the staff can heat the liquid inside the liquid cup 5. When the liquid is heated, the liquid cup 5 can be placed on the inner side of the placement groove 4, and the extension rod 12 can be rotated after placement. When the extension rod 12 rotates, it will drive the bidirectional screw 73 to rotate together. The rotation of the bidirectional screw 73 will drive the first clamping plate 75 and the second clamping plate 76 to move toward each other. The first heat-insulating hollow block 61 and the second heat-insulating hollow block 62 rotate in the opposite direction, and when the first clamping plate 75 and the second clamping plate 76 move to the outside of the liquid holding cup 5, the first heat-insulating hollow block 61 and the second heat-insulating hollow block 62 can keep the temperature inside the liquid holding cup 5 warm by the hot water flowing inside themselves, so that the temperature inside the liquid holding cup 5 can be kept in a constant temperature state as much as possible, and the staff can observe the display result of the temperature display meter 681 after detecting the temperature, so as to facilitate the staff to control the state of the heating plate 692. When the temperature is low, the heating plate 692 can be increased or started for use, and when the temperature is low, the heating plate 692 can be turned off or reduced for use, thereby achieving the effect of keeping the liquid inside the liquid holding cup 5 warm, so that the liquid inside the liquid holding cup 5 can be kept in a constant temperature state as much as possible.
