DETAILED DESCRIPTION Example One

[0020] As Figures 1-4 shown, the sample shaking device for medical detection provided by the embodiment includes a base 1, a containing cylinder 3 and a shaking mechanism.

[0021] The inside of the containing cylinder 3 is provided with an elastic pad 10, the inside of the elastic pad 10 is provided with a test tube, the port of the containing cylinder 3 is provided with a cover plate 25, the cover plate 25 is provided with three equidistantly distributed cylinder sleeves 26, the cylinder sleeves 26 are sleeved on the containing cylinder 3, the test tube containing the sample is placed in the containing cylinder 3, then the cylinder sleeves 26 on the cover plate 25 are sleeved on the through port of the containing cylinder 3, so that the test tube does not fall off when shaking, and the cooperatively arranged elastic pad 10 avoids the test tube from being damaged. The containing cylinder 3 is provided with an upper fixed ring 4 and a lower fixed ring 5, the upper fixed ring 4 and the lower fixed ring 5 are both provided with a connecting shaft 6, the two connecting shafts 6 are respectively coaxially provided with a first convex ring 7 and a second convex ring 8, and the first convex ring 7 is rotationally arranged in the inside of the support frame 2.

[0022] The shaking mechanism includes a connecting plate 9, a stop block 15 provided on the connecting plate 9 and having an arc surface, a mounting seat 11 provided on the base 1, a motor 12 provided on the mounting seat 11, a main shaft 13 drivingly connected with the motor 12, and an abutment wheel 14 coaxially provided on the main shaft 13. The second convex ring 8 is rotationally arranged in the inside of the connecting plate 9, the abutment wheel 14 has six annularly arrayed protrusions, the protrusions and the stop block 15 abut each other, the base 1 is provided with two fixed frames 16, and the main shaft 13 is rotationally connected with the fixed frames 16.

[0023] When the test tube needs to be shaken to mix the sample evenly in this embodiment, the motor 12 is started to drive the main shaft 13 to rotate, the main shaft 13 drives the abutting wheel 14 to rotate, the abutting wheel 14 rotates to make the protrusions thereon constantly collide with the stop block 15 of the connecting plate 9, and then the connecting plate 9 drives the containing cylinder 3 to shake through the second protruding ring 8 and the connecting shaft 6. At this time, the first protruding ring 7 and the second protruding ring 8 rotate relative to the support frame 2 and the connecting plate 9 respectively, which not only has a suitable shaking amplitude to ensure the mixing effect of the sample, but also is simple and convenient to operate, and has good practicability. Embodiment two

[0024] As shown in Figure 1 and Figure 4 , a sample shaking device for medical detection is provided in this embodiment. Compared with embodiment one, two stabilizing assemblies are arranged on the base 1 in this embodiment. The stabilizing assembly comprises a vertical block 17 arranged on the base 1, a connecting rod 18 arranged on the connecting plate 9, and a disc 19 coaxially arranged on the connecting rod 18. The disc 19 is slidingly arranged in the vertical block 17. The vertical block 17 is provided with a through hole and a circular groove. The radius of the disc 19 is greater than the radius of the through hole, and the disc 19 is located in the circular groove.

[0025] In this embodiment, when the connecting plate 9 reciprocally swings, the connecting rod 18 is shaken, the connecting rod 18 drives the disc 19 to slide in the circular groove in the vertical block 17, thereby limiting the direction perpendicular to the surface of the connecting plate 9, improving the structural strength and stability of the shaking mechanism, and making the stop block 15 and the abutting wheel 14 stably collide. The size design of the circular hole and the disc 19 can avoid the disc 19 from being separated from the circular groove. Embodiment three
