Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0025] The following is combined with Figure 1-8 The utility model is further described.

[0026] In order to solve the problems existing in the background technology, the present application proposes the following technical solutions: an efficient anti-splash test tube cleaning tool, comprising a screw 1, the external thread of the screw 1 is connected with a threaded sleeve 2, and one end of the threaded sleeve 2 is provided with multiple groups of external connecting sleeves 3, and the external connections are detachably fixed, wherein one external connecting sleeve 3 is detachably fixedly connected to the threaded sleeve 2, and a first bristle 5 is fixedly connected to the external connecting sleeve 3, and the external sleeve of the screw 1 is provided with multiple groups of internal connecting sleeves 9, and the external side of the internal connecting sleeve 9 is fixedly connected with a second bristle 10, and the bottom of the screw 1 is detachably fixedly connected with a resistance block 8, which supports the internal connecting sleeve 9. Through multiple internal connecting sleeves 9 and external connecting sleeves 3 that can be detached from each other, the brushing range formed by the corresponding first bristles 5 and second bristles 10 can be adjusted according to the length of the test tube, and the test tube can be fully cleaned.

[0027] In the utility model, the number of the outer connecting sleeve 3 and the inner connecting sleeve 9 is adjusted according to the length of the test tube, and multiple inner connecting sleeves 9 are connected to each other, and multiple outer connecting sleeves 3 are connected to each other, so that the second brush can completely cover the inside of the test tube, which is convenient for rotating brushing and pulling brushing. In addition, after cleaning is completed, in the process of pulling out the screw 1, due to the mutual brushing cooperation of the inner connecting sleeve 9 and the outer connecting sleeve 3, the outer connecting sleeve 3 can also prevent the second brush from bringing out liquid during the pulling out process, thereby avoiding liquid splashing.

[0028] In a further design of this embodiment, the height of the outer connecting sleeve 3 is three centimeters to five centimeters, preferably four centimeters, and the height of the inner connecting sleeve 9 is two centimeters to three centimeters, preferably three centimeters.

[0029] The height of the screw rod 1 is 20 to 30 centimeters, preferably 30 centimeters. In addition, in order to facilitate rotation, multiple groups of anti-slip convex strips are fixedly connected to the outside of the outer connecting sleeve 3.

[0030] In a further design, a threaded ring 4 is fixedly connected to one end of the external connection sleeve 3, a first thread groove 6 is provided at the other end of the external connection sleeve 3, and a second thread groove 7 is provided at one end of the threaded sleeve 2. The threaded connection between the threaded ring 4 and the first thread groove 6 allows the adjacent external connection sleeves 3 to be connected.

[0031] Among them, the two ends of the inner connecting sleeve 9 are fixedly connected with a magnet ring 11, and the magnet ring 11 is set with opposite poles repelling each other. The two adjacent inner connecting sleeves 9 can be connected to each other through the mutual adsorption and fixation of the magnets.

[0032] Among them, a bolt 12 is fixedly connected to the outside of the interference block 8, and a threaded hole 13 is provided at one end of the screw rod 1. The bolt 12 is threadedly connected to the threaded hole 13. After the inner connecting sleeve 9 is put on the outside of the screw rod 1, the bolt 12 is turned to install the interference block 8 at the bottom of the screw rod 1. The inner connecting sleeve 9 can be supported by the interference block 8.

[0033] In order for those skilled in the art to fully understand the technical solution, the method of using this embodiment is as follows:

[0034] First, adjust the number of outer connecting sleeves 3 and inner connecting sleeves 9 according to the length of the test tube so that the second brush can completely cover the inside of the test tube;

[0035] The two adjacent external connection sleeves 3 are threadedly connected to each other through the threaded ring 4 and the first thread groove 6 to achieve splicing installation. Then, the threaded ring 4 on the outside of one of the external connection sleeves 3 is connected to the second thread groove 7. In this way, the connection between the external connection sleeve 3 and the threaded sleeve 2 is achieved. The outside of the test tube can be cleaned by using multiple sets of spliced ​​external connection sleeves 3;

[0036] In addition, according to the length of the test tube, a certain number of inner connecting sleeves 9 are selected, and the inner connecting sleeves 9 are fixed to each other by adsorption through the magnetic ring 11, and then the inner connecting sleeves 9 are sleeved on the outside of the screw 1. After completion, the resistance block 8 is connected to the threaded hole 13 through the bolt 12, and the resistance block 8 blocks and supports the inner connecting sleeve 9. Then, the threaded sleeve 2 is rotated to allow the threaded sleeve 2 to resist and fix the inner connecting sleeve 9, so that the inner connecting sleeve 9 is firmly installed on the outside of the screw 1;

[0037] In this way, the number of the inner connecting sleeve 9 and the outer connecting sleeve 3 can be adjusted as needed, so that the second bristles 10 completely cover the inner wall of the test tube, and then the screw 1 is inserted into the test tube. The second bristles 10 completely cover the inner cavity of the test tube, and the first bristles 5 cover the outside of the test tube. At this time, whether the screw 1 is rotated or reciprocated, the test tube can be fully cleaned;

[0038] After cleaning is completed, the screw rod 1 can be pulled out. During the pulling out process, the outer connecting sleeve 3 can also block the cleaning liquid splashing during the pulling out process due to the mutual washing cooperation between the inner connecting sleeve 9 and the outer connecting sleeve 3.

[0039] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can be customized according to the description in the specification and the drawings. The specific connection methods of each part adopt conventional means such as mature bolts 12, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology, and the circuit connection adopts the conventional connection method in the existing technology. It will not be described in detail here. The content not described in detail in this specification belongs to the existing technology known to professional and technical personnel in this field.
