In the present invention, the terms "first", "second", "third", and the like are used for distinguishing names, rather than representing specific numbers and orders.

In some embodiments, referring to fig. 1-2, a microcentrifuge tube lid opener of the present invention comprises:

the handle comprises a handle 1, wherein a holding piece 2 is arranged at a first end of the handle 1, and a driving piece 3 is sleeved at a second end of the handle 1;

the handle 1 is provided with two opening cover parts 4, wherein the opening cover parts 4 are provided with a first extending part 401 and a second extending part 402 which face the same direction, one side of the first extending part 401 facing the second extending part 402 is provided with a driven part 403, and when the handle 1 is rotated, the driving part 3 drives the two opening cover parts 4 to approach to or separate from each other through the two driven parts 403 respectively.

When the pipe closure of different specifications uncaps, through twist grip 1 for driving piece 3 drives two respectively through two followers 403 and opens cover piece 4 and keep away from each other, adjusts to can centre gripping pipe closure both ends after, twist grip 1 again, drives two and opens cover piece 4 and be close to each other, thereby presss from both sides tight pipe closure, prizes the pipe closure to one side through handle 1 afterwards, thereby opens the pipe closure.

In some embodiments, as shown with reference to fig. 1 and 3, two followers 403 are provided on each side of the driving member 3. The two driven members 403 are respectively arranged on two sides of the driving member 3, so that the two driven members are independently driven by the driving member 3, and the whole structure is more stable in operation.

In some embodiments, referring to fig. 1 and 3, the driving member 3 is a gear, and the driven member 403 is a rack, and the gear is engaged with the rack. The transmission structure of the gear and the rack is simple, the transmission efficiency is high, and when the gear rotates along with the handle 1, the moving directions of the racks on two sides are opposite, so that the two cover opening parts 4 can be synchronously far away or close to each other.

In some embodiments, as shown in FIG. 1, the bottom of the cap 4 is provided with a grip 404 for snapping over the lid of a microcentrifuge tube. Through set up clamping part 404 in the bottom of uncapping piece 4, can joint the tube cap of microcentrifuge tube more stably to avoid this uncapping ware to produce the phenomenon that breaks away from when uncapping the microcentrifuge tube.

In some embodiments, referring to fig. 1, the clamping portion 404 is provided with a clamping groove 405, and the clamping groove 405 is clamped with a tube cover of a micro centrifugal tube. The clamping groove 405 is preferably long, the height of the clamping groove is close to the thickness of a tube cover of the micro-centrifuge tube, the tube cover of the micro-centrifuge tube is more stable after being clamped into the clamping groove 405, the stability of the micro-centrifuge tube during opening the cover is further improved, and the micro-centrifuge tube is prevented from being separated from the clamping groove during opening the cover.

In some embodiments, referring to fig. 1, the grip 2 is a round handle, and the round handle is sleeved on the handle 1. The user can more conveniently hold the holding part 2 through the round handle, and the holding part can continuously rotate in the rotating process without pause.

In some embodiments, referring to fig. 1, the bottom of the round handle is provided with a curved portion 201 to facilitate gripping. The flexion through the round handle bottom can be laminated with user's finger, when being more convenient for grip, when twist grip 1, finger and flexion laminating increase the frictional force between finger and the handle 1 for handle 1 is rotated more easily.

In some embodiments, as shown in fig. 1, the round handle is an integral structure with the handle 1. The integral formation of the round shank with the handle 1 enables a higher structural strength and thus a higher load to be borne.

In some embodiments, referring to fig. 1 and 4, the handle further includes a limiting member 5, a through hole is formed in the limiting member 5, the handle 1 is inserted into the through hole, third extending portions 501 facing the same direction are disposed on two sides of the limiting member 5, and when the two opening cover members 4 are close to or far from each other, the first extending portion 401 and the second extending portion 402 are respectively abutted against the two third extending portions 501. When the two opening cover parts 4 are close to or far away from each other, the first extension part 401 and the second extension part 402 are respectively abutted against the two third extension parts 501, so that the two opening cover parts 4 are limited by the third extension parts 501, and the stability of the opening cover parts 4 in moving is improved.

In some embodiments, referring to fig. 4, the bottom end of the third extension 501 is further provided with a laterally extending fourth extension, which is located below the opening cover 4 to receive the opening cover 4. The bottom of the opening cover part 4 is supported by the fourth extending part, so that the opening cover part 4 is more stable in movement, and the opening cover part 4 can be further prevented from being separated from the limit of the limit part 5.

It should be understood that the above examples are only for clarity of illustration and are not intended to limit the embodiments. Other variations and modifications will be apparent to persons skilled in the art in light of the above description. This need not be, nor should it be exhaustive of all embodiments. And obvious changes and modifications can be made without departing from the scope of the invention.
