The two clamping parts 51 extend obliquely outward, and the protruding clamping parts 52 are clamped in the corresponding annular clamping groove 108 formed on the inner wall of the positioning sleeve 107 and matched with the annular clamping groove 108.

[0052] A transverse positioning rod 70 with a rectangular cross section is inserted into the transverse insertion hole 121, the outer end of the transverse positioning rod 70 extends out of the outer end of the transverse insertion hole 121 and is formed with a pressing portion 71, the inner end of the transverse positioning rod 70 is a positioning portion, the top surface of the positioning portion is an oblique wall extending inward and downward, the positioning portion is inserted into a positioning slot 62 formed on the lower inner side wall of the corresponding central positioning column 60, the top surface of the positioning slot 62 is an oblique wall, which is tightly attached to and matched with the top surface of the positioning portion;

The outer end face of the pressing portion 71 is a spherical surface, which is in close contact with the inner wall of the annular guide portion 19. The annular guide portion 19 is formed with an inner groove 191 on the inner wall facing the transverse material feeding slot 21. The inner wall surface of the inner groove 191 is an arc-shaped wall surface. The outer end face of the pressing portion 71 is in close contact with the inner wall surface of the inner groove 191 to achieve cooperation.

[0054] Furthermore, a vertical guide groove is formed on the inner side wall of the positioning socket 106 at the upper part of the positioning sleeve 107, the lifting sleeve 80 is inserted into the upper part of the positioning socket 106, and side protrusions are formed on the left and right outer walls of the top of the lifting sleeve 80, and the side protrusions are inserted into the corresponding vertical guide grooves and cooperate with the vertical guide grooves.

[0055] When the present embodiment is used, the present embodiment with all reagent assembly housings 100 installed is placed in a detection device (which is an existing commonly used detection device using a circular disc reagent material box), and the rotating shaft of the rotary servo motor of the detection device is a spline shaft, which is inserted into the spline hole in the middle of the bottom surface of the main shaft 11 to achieve driving. At the same time, the plug of the inductive electrical connection line of the detection device is plugged into the connection socket 5 at the end of the electrical connection line of the slot-type photoelectric sensor 2 to achieve electrical connection;

[0056] Then, it can be operated. When in use, the horizontal rotating plate 12 is rotated by rotating the servo motor. It rotates a certain angle so that the corresponding sensing block 1 is inserted into the sensing slot of the slot-type photoelectric sensor 2 and is sensed, indicating that it has moved into place. At this time, the corresponding reagent combination shell 100 is directly below the corresponding horizontal material taking slot 21. At this time, the pressing portion 71 of the corresponding horizontal positioning rod 70 is just opposite to the inner groove 191, so that the corresponding compression spring 81 is reset, and the lifting sleeve 80 is lowered, so that the bottom end of the vertical push rod 82 pushes the center positioning column 60 to descend. At this time, the top of the center positioning column 60 descends, so that the oblique protrusion 61 no longer presses the clamping The two retaining portions 51 are pressed against each other, and the two retaining portions 51 elastically recover, and the protruding retaining portion 52 is moved out of the annular retaining groove 108 of the positioning sleeve 107. At the same time, the corresponding transverse positioning rod 70 is moved laterally outward (the end of its positioning portion will also be partially inserted into the positioning slot 52), so that the outer end surface of the pressing portion 71 is tightly attached to the inner wall surface of the inner groove 191. At this time, the corresponding reagent combination shell 100 is in a loose state, and the material taking mechanism of the detection equipment can extend into the transverse material taking slot 21, and clamp the corresponding reagent combination shell 100, and take it out of the transverse material taking slot 21, so that the liquid in the reagent tube 200 in the reagent combination shell 100 can be detected, and the material taking is convenient.

[0057] Moreover, when no material is taken, as long as the pressing portion 71 is not facing the inner groove 191, it can be ensured that all reagent assembly housings 100 are in a locked state;

[0058] A damping layer is fixed on the inner wall of the annular guide portion 19 in the present embodiment, which has a certain damping effect on the pressing portion 71, so as to prevent the horizontal rotating plate 12 from rotating too easily when the present embodiment is moved or transported. The horizontal rotating plate 12 can only be driven to rotate by rotating the servo motor or manually rotating the main rotating shaft 11. In this way, when the reagent combination housing 100 is installed, as long as the pressing portion 71 does not face the inner groove 191, all reagent combination housings 100 can be locked and not easily loosened.

[0059] When installing the reagent combination housing 100 in this embodiment, it is necessary to manually rotate it so that the installation position of the horizontal rotating plate 12 is directly below the horizontal material extraction slot 21, so that the reagent combination housing 100 installed with the reagent tube 200 to be tested can be installed to the corresponding position of the horizontal rotating plate 12, and it is firmly installed.

[0060] Finally, it should be pointed out that the above embodiments are only representative examples of the present invention. Obviously, the present invention is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention should be considered to belong to the protection scope of the present invention.

The right end surface of the protrusion is a spherical surface and is embedded in the positioning concave hole in the middle part of the left side wall of the horizontal rotating plate (12). The rotating part of the locking bolt (7) is located on the outside of the bent connection block (6).

10. A biochemical detection kit according to claim 9, characterized in that: A right-bent connecting block (8) is fixed on the top surface of the right side of the upper cover plate (20), and a second lower groove is formed on the lower part of the left side wall of the right-bent connecting block (8). The screw portion of the second locking bolt (9) is screwed into a screw connection through hole formed on the inner side wall of the second lower groove. The left end of the screw portion of the second locking bolt (9) extends out of the inner side wall of the second lower groove and is formed with a protrusion. The end face of the protrusion is a spherical surface, which corresponds to the positioning concave hole in the middle part of the left side wall of the horizontal rotating plate (12). The rotating part of the second locking bolt (9) is located on the outside of the right-bent connecting block (8).
