[0021] like Figure 1 , Figure 3 , Figure 4As shown, this embodiment provides a reagent bottle 5 positioning assembly capable of arbitrarily adjusting the placement angle, comprising a reagent bottle 5 and a bottle body positioning seat, wherein the bottle body positioning seat comprises a base plate 1 and a bottle holder 4; the base plate 1 is composed of a plurality of standard plates 11 detachably connected at the side ends; the bottle holder 4 is composed of a bottle sleeve 41 and a positioning gear ring 44 connected to the lower end of the bottle sleeve 41, and the lower end of the reagent bottle 5 is sleeved in a slot in the middle of the bottle sleeve 41; at least one stepped assembly groove is provided on the base plate 1 or each standard plate 11 of the base plate 1, and the assembly groove is composed of an upper slot body 14 and a lower slot body 15, and a positioning gear 3 capable of circumferential rotation under the action of external force is installed in each lower slot body 15, and a gear ring assembly space 16 matching the positioning gear ring 44 is formed between the outer end surface of the gear and the lower slot body 15. When in use, the lower end of the reagent bottle 5 is directly sleeved in the bottle sleeve 41 of the bottle holder 4, and then the positioning gear ring 44 at the lower end of the bottle holder 4 is aligned and inserted with the gear ring assembly space 16 formed in the base plate 1, so that the positioning gear ring 44 cooperates with the positioning gear 3 to realize the assembly of the bottle holder 4. At this time, if you want to adjust the positioning angle of the bottle holder 4 and the reagent bottle 5, you can adjust the placement angle by rotating the bottle holder 4. At the same time, since only the lower end of the reagent bottle 5 is sleeved on the bottle sleeve 41, there is no obstruction around, which is also convenient when taking.

When installing, insert downward, and when replacing or removing, pull the bottle holder 4 upward, and the installation structure between the bottle holder 4 and the base plate 1 is stable.

[0022] The upper edge of the bottle sleeve 41 can extend out of the upper end surface of the bottom plate 1, or can be placed in the upper groove 14 of the bottom plate 1. When the bottle sleeve 41 is placed in the upper groove 14, in order to facilitate the replacement or removal of the bottle holder 4, one or two outwardly extending pull plates 45 or pull ropes can be provided on the upper edge of the bottle sleeve 41, so that there is a better traction point when removing it.

In this way, this arrangement can ensure that the positioning between the reagent bottle 5 and the bottle sleeve 41 is tighter, and ensure that the reagent bottle 5 will not rotate in the bottle sleeve 41 under the action of external force, and its placement position is fixed. In a specific application, if the bottle sleeve 41 extends out of the bottom plate 1, that is, the height of the bottle sleeve 41 is greater than the depth of the upper groove body 14, the limiting protrusion 51 can be set near the middle of the reagent bottle 5, and the limiting groove 43 is set at the upper end of the bottle sleeve 41.

[0024] Furthermore, a handle 52 is provided on the reagent bottle 5, and the limiting protrusion 51 and the handle 52 are located on the same side and are placed under the handle 52. In this way, the provided handle 52 is convenient for taking the reagent bottle 5, and the limiting protrusion 51 is arranged under the handle 52, so that when placing the reagent bottle 5, the position and orientation of the handle 52 can be confirmed by the position of the limiting protrusion 51 and the limiting groove 43 after the reagent bottle 5 is positioned, so that the handle 52 is placed in a position that is convenient for the experimenter to take.

In this way, the positioning gear 3 can rotate around the mounting shaft under the action of external force, and there will be no interference in the rotation of the positioning gear ring 44.

[0026] Furthermore, the positioning gear 3 has a plurality of positioning teeth evenly distributed in the circumferential direction, a clamping space is formed between each two adjacent positioning teeth, and a circle of clamping teeth is provided in the ring body of the positioning gear ring 44, and the clamping teeth correspond to the clamping spaces one by one. In this way, the positioning gear 3 and the positioning gear ring 44 are connected by sleeve arrangement and tooth matching to achieve synchronous rotation.

[0027] Furthermore, the positioning teeth are triangular or trapezoidal in shape, so that the inner width of the positioning teeth is greater than the outer width, the structural strength is good, and the locking teeth are easy to insert.

[0028] Further, the standard plate 11 is a rectangular plate with a row of notches 12 and protrusions 13 on two opposite sides, or a rectangular plate with a row of notches 12 and protrusions 13 corresponding to each other on all sides, and two adjacent standard plates 11 are connected after the protrusions 13 and notches 12 cooperate to form a rectangular bottom plate 1 or a cross-shaped bottom plate 1 or a T-shaped bottom plate 1. In this way, after the notches 12 and protrusions are set on the standard plate 11, the connection between the two adjacent standard plates 11 can be achieved by the way of notches 12 and protrusions cooperating. When in use, different numbers of standard plates 11 can be selected according to the number of reagent bottles 5 to be placed.

[0029] Further, the notch 12 is rectangular or dovetail-shaped. In this way, the dovetail-shaped notch 12 makes the connection more stable, and during installation, after alignment, the notch 12 and the projection can be buckled together by knocking the standard plate 11 at the upper end. Example
