[0048] Example 3

[0049] Reference Figure 7 , which is the third embodiment of the present utility model, and is based on the first two embodiments.

[0050] Specifically, the gripping assembly 200 further includes a limiting member 203, which is disposed on one side of the rotating cover 202a. The limiting member 203 includes a limiting tooth 203a. A limiting groove 101-3 is provided on the surface of the rotor 101, and the limiting tooth 203a slides in the limiting groove 101-3.

[0051] The limiting tooth 203a fits the limiting groove 101-3 and slides in the limiting groove 101-3, so that the sliding path of the limiting tooth 203a is restricted, so that the limiting tooth 203a will not move upward.

[0052] Specifically, a pressing groove 202a-3 is opened on the surface of the rotating cover 202a, and the limiting tooth 203a is set in the pressing groove 202a-3. The surface of the limiting tooth 203a is rotatably connected to a small rotating shaft 203b, and the small rotating shaft 203b is fixedly connected to the rotating cover 202a.

[0053] The limiting teeth 203a are rotatably connected to the surface of the small rotating shaft 203b, so that the limiting teeth 203a can limit the rotating cover 202a, so that the rotating cover 202a is limited and can only rotate.

[0054] Specifically, the limiting member 203 further includes a pressing shell 203c. The pressing shell 203c is disposed on one side of the pressing groove 202a-3, and the pressing shell 203c is fixedly connected to the rotating cover 202a.

[0055] The pressing shell 203c is used to protect the limiting teeth 203a to prevent other objects from accidentally touching the limiting teeth 203a.

[0056] Specifically, a button groove 203c-1 is opened on the surface of the pressing shell 203c, and a button 203d is inserted into the button groove 203c-1. The button 203d presses against one end of the limiting tooth 203a. A spring 203e is fixedly connected to the inner wall of the pressing shell 203c, and the other end of the spring 203e is fixedly connected to the other end of the limiting tooth 203a.

[0057] By pressing the button 203d, the limiting tooth 203a can be separated from the pressing groove 202a-3, so that the rotating cover 202a can be separated from the test tube compartment 101-1. The spring 203e is used to reset the limiting tooth 203a after pressing the button 203d.

[0058] When in use, first put the fixed ring 201a of the twisting member 201 into the test tube compartment 101-1, and then put the entire twisting member 201 in order, so that the sliding block 201e falls into the bottom of the slide groove 101-2. At this time, the rotating ring 201c is attached to the top of the test tube compartment 101-1, and the rotating cover 202a is covered so that the third ratchet 202b of the rotating cover 202a and the second ratchet 201d on the top of the rotating ring 201c are engaged with each other. At this time, insert the test tube into the placement hole 202a-1, rotate the rotating cover 202a, so that the rotating ring 201c rotates. Since the sliding block 201e of the fixed ring 201a can only be The sliding groove 101-2 slides up and down, thereby causing the connecting soft belt 201b between the rotating ring 201c and the fixed ring 201a to rotate and cover the test tube, and the connecting soft belt 201b is provided with a rubber layer. The connecting soft belt 201b is made of elastic soft material and will not slip when fitting the test tube. When the test tube is tightly covered, the rotating cover 202a is loosened. Since the pawl 202c fits with the first ratchet 102, the first ratchet 102 of the rotating cover 202a can only rotate forward and cannot rotate backward, thereby fixing the rotating cover 202a and the rotating ring 201c, thereby fixing the test tube.

[0059] When using the rotating cover 202a, first press the pressing button 203d to push one side of the limiting tooth 203a in the pressing groove 202a-3. Under the action of the rotating shaft, the other end of the limiting tooth 203a is away from the limiting groove 101-3 opened on the surface of the test tube warehouse 101-1. At this time, the rotating cover 202a can be covered on the surface of the test tube warehouse 101-1. When the pressing button 203d is released, the spring 203e will reset the pressing button 203d, and the limiting tooth 203a will be re-attached to the limiting groove 101-3, limiting the rotating cover 202a, so that the rotating cover 202a can only rotate and will not separate from the test tube warehouse 101-1 to cause an accident.
