Description

Technical Field

[0001] The present invention belongs to the technical field of gene sequencing, and in particular relates to a clamping tool and a sample adding clamping tool. Background Art

[0002] Gene sequencing involves inserting a gene chip into a gene sequencer for testing. During the automated gene sequencing process, an automated spotting mechanism first spots the sample onto the gene chip, which is secured to a fixture. Due to the sequencer's entry requirements for the inserted gene chip, the gene chip must be flipped 180° during the spotting step before being inserted into the sequencer for testing. During the flipping process, the gene chip must not fall from the fixture, and the fixture must be detachable when the gene chip is inserted into the sequencer.

[0003] In order to achieve the above purpose, it is necessary to design a clamping tool. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a clamping tool and a sample adding clamping tool to clamp the gene chip and ensure that the gene chip will not fall during the flipping process.

[0005] To achieve this object, the present invention adopts the following technical solutions:

[0006] A clamping tool, comprising:

[0007] A fixing assembly, comprising a fixing member and a positioning member, wherein the fixing member is provided with a mounting groove, the positioning member is arranged in the mounting groove, and the positioning member is provided with a positioning portion for positioning the clamped member;

[0009] a reset assembly, which is arranged between the upper cover and the fixing assembly, and is used to automatically open the upper cover;

[0010] a locking assembly, disposed between the upper cover and the fixing assembly, the locking assembly being used to lock the upper cover closed;

[0011] When the upper cover is closed, the clamped member is clamped between the positioning member and the upper cover.

[0012] Preferably, the upper cover and the fixing member are rotatably connected via a rotating shaft.

[0013] Preferably, the reset component includes:

[0014] a torsion spring mounting member, rotatably mounted on the rotating shaft, wherein the torsion spring mounting member is connected to the upper cover;

[0018] The second connecting member is provided on the fixing assembly, and the first connecting member and the second connecting member can be buckled or opened.

[0019] Preferably, the first connecting member includes a hook, one end of which is connected to the upper cover and is located on both sides of the clamped member;

[0020] The second connecting member includes a hook connecting member, a sliding groove is formed on the fixing member below the positioning member, and one end of the hook connecting member extends into the sliding groove;

[0021] The hook connector is provided with a slot, and the other end of the hook can be locked in the slot.

[0022] Preferably, the positioning member is further provided with a first positioning groove, and the clamped member is provided with an end positioning protrusion that cooperates with the first positioning groove.

[0023] Preferably, a clamping connection portion is provided on the fixing member, and the external device clamps the fixing member through the clamping connection portion.

[0024] A sample loading and clamping tool comprises a base, a sample loading seat and the clamping tool, wherein the base is provided with a second positioning groove, and the clamping tool is placed in the second positioning groove;

[0026] A side positioning protrusion is provided on the side wall of the end of the clamped part extending out of the clamping tool;

[0027] The sample loading seat is placed on the base. An open positioning slot is provided on the sample loading seat. The side positioning protrusion is clamped in the open positioning slot.

[0028] Preferably, a sample loading channel communicating with the sample loading port is provided on the sample loading seat, and a diameter of the sample loading channel gradually decreases from the upper opening downward.

[0029] Compared to the prior art, the present invention has the following advantages: the upper cover can rotate relative to the fixing assembly, allowing it to be opened or closed. A reset assembly automatically opens the upper cover, and a locking assembly secures the upper cover when it is closed. When the upper cover is locked, the clamped part is clamped between the positioning member and the upper cover.
