[0034] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0035] Example 1: A biological sample processing device, see [link to example]. Figures 1 to 5 It includes a homogenizer body 1, a cover plate 2 is rotatably arranged at the top of the working chamber of the homogenizer body 1, and also includes a turntable 3 and a test tube tray 4;

[0036] Turntable 3 is connected to the rotating shaft inside the working chamber of homogenizer body 1; test tube tray 4 is embedded in the groove on the top side of turntable 3; wherein, grooves 301 are respectively opened on both sides of turntable 3, and guide blocks 401 are respectively fixed on both sides of test tube tray 4, and guide blocks 401 are inserted and matched with grooves 301.

[0037] This utility model, by setting up a turntable 3, a test tube tray 4, a groove 301 and a guide block 401, has the advantage that the test tube tray 4 embedded in the turntable 3 has the guide block 401 protruding, which makes it easy to hold the guide block 401 to place and take out the test tube tray 4, and solves the problem that it is not convenient to reach into the limited space inside the turntable 3 when taking it out.

[0038] Specifically, the guide block 401 has a perforation; however, the guide block 401 does not contact the inner wall of the working chamber of the homogenizer body 1. Fingers can pass through the perforation to pick up the guide block 401 within a limited space.

[0039] Furthermore, a rubber sleeve 402 is embedded and fixed in the perforation on the guide block 401. The rubber sleeve 402 is more comfortable for fingers to touch.

[0040] Furthermore, both the upper and lower ends of the rubber sleeve 402 are designed to be curved. Fingers will not feel any discomfort when touching the curved surface.

[0041] It is worth noting that a positioning structure 5 is arranged on one side of the turntable 3;

[0042] The positioning structure 5 includes a fixing block 501, a screw 502, and a rotating handle 503; the fixing block 501 is fixed to one side of the turntable 3; the screw 502 is threaded through a screw hole on the fixing block 501; the rotating handle 503 is fixed to the outer end of the screw 502; wherein, the inner end of the screw 502 is inserted into a positioning hole 4011 opened on a guide block 401.

[0043] This utility model, by setting a fixing block 501, a screw 502 and a rotating handle 503, has the advantage of positioning a guide block 401 after the test tube tray 4 is embedded in the turntable 3, thereby keeping the test tube tray 4 stably embedded in the turntable 3.

[0044] Working principle: Using the device of this utility model, the cover plate 2 is rotated open, and the test tube tray 4 containing the sample test tubes is embedded into the groove of the turntable 3. The guide block 401 is inserted into the groove 301. The positioning hole 4011 on the guide block 401 corresponds to the inner end of the screw 502. After the test tube tray 4 is embedded into the groove of the turntable 3, the handle 503 is rotated, and the screw 502 rotates, so that the screw 502 moves inward relative to the fixed block 501 until the inner end of the screw 502 is inserted into the positioning hole 4011, keeping the test tube tray 4 stably embedded in the turntable 3. The cover plate 2 is closed, and the rotating structure in the homogenizer body 1 drives the turntable 3 to rotate. The test tube tray 4 rotates accordingly to homogenize the biological sample.
