[0010] The utility model provides a blood specimen shaker. Compared with the existing technology, it has the following beneficial effects:

[0011] (1) The utility model drives the reciprocating screw to rotate through a motor, and the reciprocating screw drives the tooth plate to move back and forth through the threaded sleeve.

Implementation

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] See also Figure 1-5 The utility model provides a technical solution: a blood specimen shaker, comprising a fixed frame 1 and a plurality of anticoagulant tubes 2 located inside the fixed frame 1, both sides of the fixed frame 1 are rotatably connected with rotating rods 3 through openings, a swing plate 4 is fixedly connected between the opposite sides of the two rotating rods 3, a plurality of mounting holes 5 adapted to the anticoagulant tubes 2 are opened on the top of the swing plate 4, a fixed box 6 is fixedly connected to one side of the fixed frame 1, and a driving mechanism 7 is arranged inside the fixed box 6.

[0021] Furthermore, in order to facilitate the reciprocating shaking of the anticoagulant tube 2, the driving mechanism 7 includes a motor 71, which is a servo motor, electrically connected to an external power supply, and controlled by a control switch. The output shaft of the motor 71 is fixedly connected to a reciprocating screw 72 through a coupling, and one end of the reciprocating screw 72 is rotatably connected to the front part of the inner cavity of the fixed box 6 through a bearing. A slide groove 74 is provided on one side of the fixed frame 1 and located inside the fixed box 6. The interior of the slide groove 74 is slidably connected to the outer surface of the threaded sleeve 73 through a slider, and a gear 75 is fixedly connected to the outer surface of the rotating rod 3. A tooth plate 76 matching the gear 75 is fixedly connected to the upper part of the outer surface of the threaded sleeve 73 through a fixed block.

[0022] It should be noted that the threaded sleeve 73 can only move within the range of the sliding groove 74, so that the swinging angle of the swinging plate 4 will not exceed ninety degrees.

[0023] Furthermore, in order to limit the anticoagulation tube 2, a plurality of limit frames 8 compatible with the anticoagulation tube 2 are fixedly connected to the bottom of the swing plate 4, and the front and rear parts of the limit frame 8 are slidably connected to the extrusion rod 9 through openings, and one end of the extrusion rod 9 is fixedly connected with an arc-shaped extrusion plate 10 compatible with the anticoagulation tube 2 and located inside the limit frame 8, and the other end of the extrusion rod 9 is fixedly connected with a shielding plate 11, and a spring 12 is sleeved on the outer surface of the extrusion rod 9 and located between the arc-shaped extrusion plate 10 and the limit frame 8, and an inclined surface 13 is opened above the opposite side of the two arc-shaped extrusion plates 10.

[0024] When in use, the anticoagulation tube 2 filled with blood is passed through the mounting hole 5, and the anticoagulation tube 2 will move into the limiting frame 8, and the anticoagulation tube 2 will squeeze the inclined surfaces 13 on the two arc-shaped squeezing plates 10, and the two arc-shaped squeezing plates 10 will move forward and backward respectively. After the anticoagulation tube 2 is completely inserted into the limiting frame 8, the two arc-shaped squeezing plates 10 clamp the anticoagulation tube 2 through the action of the spring 12;
