Preferably, the mixing plate 43 is provided with six cup positions, i.e., six reaction cups 44 can be placed at one time. The stepping motor 41 is arranged on the blending bottom plate 2, and the blending plate 43 and the stepping motor 41 are respectively positioned above and below the blending bottom plate 2. The blending plate supporting shaft 42 penetrates through the blending bottom plate 2, one end of the blending plate supporting shaft is connected with the stepping motor 41, and the other end of the blending plate supporting shaft penetrates through the blending bottom plate 2 and then is vertically connected with the center of the blending plate 43. The stepping motor 41 is connected to the kneading plate support shaft 42 and drives the kneading plate 43 to rotate in steps, and drives the plurality of reaction cups 44 to rotate about the central axis of the kneading plate 43, in other words, about the central axis of a circle formed by the projection lines of the plurality of cup positions or the reaction cups 44 on the kneading plate 43. Each stepwise rotation spans the distance between two reaction cups 44, and after each rotation, one reaction cup 44 is replaced by its neighboring reaction cup 44 in the spatial position before the rotation.

As shown in FIG. 3, the mixing component of the upper and lower sample-adding arms comprises a motor plate 31, a mixing rod 35, a motor 34, a linear guide rod 33 and a screw motor 32 for driving the motor plate 31 to move up and down. One end of a screw rod motor 32 is installed on the blending bottom plate 2, the other end of the screw rod motor is connected with a motor plate 31, and the motor plate 31 is driven to move along a straight line. Specifically, lead screw motor includes motor, lead screw and nut, and the lead screw is the straight line shape, and the lead screw surface is equipped with the spiral groove, and the nut cup joints at the lead screw outside and lead screw meshing, and motor board 31 is still connected to the nut, and the lead screw is connected to the motor, and motor drive lead screw is rotatory, drives the nut along lead screw axial displacement, changes the rotary motion of lead screw into the linear motion of nut promptly, consequently drives motor board 31 and is linear motion. The principle and construction of the lead screw motor are well known to those skilled in the art and will not be described in detail herein.

One end of the linear guide rod 33 is fixed on the blending bottom plate 2, the other end of the linear guide rod passes through the motor plate 31, the motor plate 31 can move along the linear guide rod 33, and the linear guide rod 33 is vertical to the blending plate 43. The linear guide rod 33 is used for limiting the moving direction of the motor plate 31, i.e. guiding the motor plate 31, so that the motor plate 31 moves along the direction of the guide rod 33. The blending rod 35 and the motor 34 are respectively positioned below and above the motor plate 31, the motor 34 is fixed on the motor plate 31, and the motor 34 is a direct current motor. The outer side surface of one end of the mixing rod 35 is provided with a bulge. The motor plate 31 is positioned above the reaction cup 44, and the motor 34 is connected with and drives the mixing rod 35 to rotate. The movement of the mixing rod 35 thus includes two aspects, namely a linear movement in a direction perpendicular to the mixing plate 43 and a rotational movement. The linear motion drives the blending rod 35 to be located above or outside the reaction cup 44 in a lifting manner. When the mixing rod 35 is located the outside of the reaction cup 44, the outer side face of one end of the mixing rod 35 is provided with a protrusion, when the mixing rod 35 is located the outside of the reaction cup 44 and is driven to rotate, the protrusion is abutted against and drags the reaction cup 44 at intervals, so that the reaction cup 44 rotates and vibrates at the same time, and the materials in the reaction cup 44 are mixed more fully. Specifically, the height of the protrusion protruding the mixing rod 35 is larger than the distance between the mixing rod 35 and the reaction cup 22 when the mixing rod is naturally placed. That is, when the mixing rod 35 rotates to the position where the protrusion contacts the reaction cup 44, the protrusion drives the reaction cup 44 to rotate due to the friction between the protrusion and the reaction cup 44 and the natural erection of the reaction cup 22, and meanwhile, due to the set distance, the protrusion pushes the reaction cup 44 open in the direction perpendicular to the mixing rod 35, so that the reaction cup 44 vibrates. In this manner, the mixing rod 35 does not need to be in contact with the liquid in the reaction cup 44 to achieve uniform mixing of the liquid.

The motor plate 31 is also connected to the side support plate 6 for balanced up and down movement of the motor plate 31. The side supporting plate 6 is provided with a strip-shaped through hole, and the length direction of the through hole is parallel to the linear guide rod 33. One end of the motor plate 31 close to the side supporting plate 6 penetrates through the through hole and then is connected with the limiting protrusion, so that the through hole is formed to prevent the up-and-down movement of the motor plate 31 from being blocked. Spacing protruding connection motor board 31 contacts collateral branch fagging 6 simultaneously, and motor board 31 moves the position in-process to the bottom from the top, and spacing bellied top is higher than all the time the top of through-hole, support and withstand collateral branch fagging 6, prevent that motor board 31 from moving the in-process, because mixing rod 35 and motor 34 place one end weight are great and take place the slope.

The principle and operation of the present invention will be described by taking the movement of a reaction cup 44 as an example: as shown in fig. 1 to 3, a plurality of reaction cups 44 containing reagents are sequentially placed on the cup positions of the mixing plate 43, the stepping motor 41 drives the mixing plate 43 to rotate in a stepping manner, after each rotation, one reaction cup 44 is positioned below the mixing rod 35, then the screw rod motor 32 drives the motor plate 31 to descend to drive the mixing rod 35 to move downwards to the same height as the reaction cup 44, the mixing rod 35 is positioned outside the reaction cup 44, then the motor 34 drives the mixing rod 35 to rotate, the bulges on the mixing rod 35 periodically contact the reaction cup 44 to push and drag the reaction cup 44, when the reaction cup is pushed, the reaction cup is made to oscillate, and when the reaction cup is dragged, the reaction cup is made to rotate. Then the motor 34 stops driving, the screw motor 32 starts, the driving motor plate 31 rises to drive the blending rod 35 to move upwards, so that the blending rod 35 does not obstruct the movement of the reaction cup 44, and the screw motor 32 stops driving. Meanwhile, the stepping motor 41 drives the mixing plate 43 to rotate in a stepping manner for a certain span, the other reaction cup 44 moves to the lower part of the mixing rod 35, the screw motor 32 drives the motor plate 31 to descend, and the actions are repeated, so that the mixing rod 35 mixes the reagents in each reaction cup 44. Therefore, the reagents in the reaction cup 44 are fully mixed, and the blending rod 35 does not contact the reagents and cannot pollute the reagents.

Finally, it must be said here that: the above embodiments are only used for further detailed description of the technical solutions of the present invention, and should not be understood as limiting the scope of the present invention, and the modifications and adjustments made by those skilled in the art according to the above-mentioned contents of the present invention are all included in the scope of the present invention.
