[0002] During the PCR experiment, the ep tube cap often needs to be opened repeatedly. The 0.2-0.1ml PCRep tube cap is small in size and is not easy to open again after being tightly closed. Especially in clinical experiments, it wastes time and easily causes contamination, resulting in erroneous detection results. Utility Model Content

[0003] The utility model aims to provide a cover opener suitable for 0.2-0.1ml PCRep tubes, so as to solve the above problems.

[0004] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a cover opener suitable for 0.2-0.1mlPCRep tubes, comprising a cover opening part connected by a triangular guide block arranged on the front side of a curved neck hand-held pressing part, the curved neck hand-held pressing part comprising a negative pressure fork for a negative pressure tube rack, and the cover opening part comprising a tube holding fork inserted into the negative pressure fork.

[0005] Preferably, the curved neck hand-held pressing part includes a hand-held part and a connecting part for connecting the hand-held part and the negative pressure fork as a whole.

[0006] Preferably, a through slot is formed on the connecting portion, and the cover portion further comprises a main body portion which is located in the through slot and has the same contour as the connecting portion.

[0007] Preferably, an arc-shaped elastic member having one end connected to the main body is symmetrically arranged on the back side of the connecting portion.

[0008] Preferably, a pressing block arranged close to the hand-held part is provided on the front side of the main body.

[0009] Preferably, the pressing block is a silicone block.

[0010] As a preference, the curved neck hand-held pressing part is a transparent acrylic plate.

[0011] Preferably, the cover portion is a PVC plate.

[0012] In the above technical scheme, the utility model provides a lid opener suitable for 0.2-0.1ml PCRep tubes, which has the following beneficial effects: a hand-held curved-neck hand-held pressing part is inserted into the location of the PCRep tube using a negative pressure fork, and the end of the negative pressure fork is now in contact with the body of the PCRep tube, pressing so that the negative pressure fork exerts negative pressure on the tube rack, and then pressing the lid opening part, using the triangular guide block as a fulcrum, the tube fork is lifted up to open the PCRep tube lid.

[0018] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0019] like Figure 1-2 As shown, a cover opener suitable for 0.2-0.1 ml PCRep tubes, comprising:

[0020] A curved neck hand-held pressing part 1 (transparent acrylic plate) consisting of a hand-held part 12 and a connecting part 13 for connecting the hand-held part 12 and the negative pressure fork 11 as one body;

[0021] The cover opening portion 3 (PVC plate) includes a tube receiving fork 31 inserted into the negative pressure fork 11 .

[0022] When in use, the negative pressure fork 11 is a negative pressure tube holder, and then when the negative pressure fork 11 is inserted, the tube fork 31 is aligned with a PCRep tube, because the tube fork 31 here is connected by a triangular guide block 2 arranged at one end of the through groove 4 opened on the connecting part 13, so with the triangular guide block 2 as the fulcrum, the main body 32 of the opening cover part 3 passes through the through groove 4 to the back of the curved neck hand-held pressing part 1, and at this time, the back of the connecting part 13 is symmetrically provided with an arc-shaped elastic member 5 with one end connected to the main body 32, which will deform.

[0023] At the same time, the tube fork 31 removes the tube cap of the PCRep tube.

[0024] It should be noted that when the negative pressure fork 11 is inserted into the PCRep tube, in addition to the negative pressure tube holder, the end of the negative pressure fork 11 will contact the tube body of the PCRep tube to provide resistance, so that the tube fork 31 can pull off the tube cap of the PCRep tube.

[0025] Furthermore, the main body portion 32 is located in the through groove 4 and has a contour consistent with that of the connecting portion 13 .

[0026] Secondly, combined Figure 1 It can be seen that a pressing block 33 (a silicone block) is provided on the front of the main body 32 and arranged close to the hand-held part 12 .

[0027] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
