The connecting block 9 is connected with each other, a slider 8 is provided on the top of the connecting block 9, a connecting rod 10 is provided on the front and rear sides of the connecting block 9 away from the telescopic rod 3, a compression spring 23 is provided on the side where the connecting rods 10 are close to each other, and the compression spring 23 gives the two connecting rods 10 an elastic force to move away from each other, and a limit card 11 is provided on the side where the connecting rods 10 are away from each other, a first slide groove 12 is provided on both sides of the inner wall of the telescopic slot 2, and a card groove 13 is provided at both ends of the first slide groove 12, and the first slide groove 12 and the card groove 13 are both connected with the limit card 11, and an observation window 5 is provided on the side of the top of the housing 1 away from the through opening 15, and the observation window 5 is provided corresponding to the observation port 6;
[0023] In the specific implementation process, it is worth pointing out that the main structure of the telescopic pregnancy test stick is formed by the cooperation between the casing 1, the telescopic slot 2 and the telescopic rod 3. When the pregnancy test stick is not in use, the telescopic rod 3 is fixed inside the casing 1. When it needs to be used, it can be pushed out from the casing 1. The sampling hole 4 is the urine sample collection hole of the pregnancy test stick. The test strip 7 detects the concentration of HCG in the urine to confirm whether the woman is pregnant. Through the cooperation between the casing 1, the telescopic rod 3, the sampling hole 4, the observation window 5, the observation port 6 and the test strip 7, when the telescopic pregnancy test stick is used, the telescopic rod 3 is pushed out of the casing 1 to sample urine at the sampling hole 4. The urine sample enters the test strip 7. After a period of time, the test strip 7 changes color at the observation port 6. The test result is obtained by observing the color change of the test strip 7 at the observation port 6 through the observation window 5. The telescopic rod 3 is extended and retracted in the shell 1 by moving the slider 8 at the top of the shell 1, and the travel of the connecting block 9 is limited by the through port 15, so that the telescopic rod 3 can be stably moved to a fixed position, thereby improving the accuracy and reliability of the use of the telescopic pregnancy test stick. The compression spring 23 gives the two connecting rods 10 an elastic force to move away from each other. The shell 1, the telescopic slot 2, the telescopic rod 3, the slider 8, the connecting block 9, the connecting rod 10, the limit card 11, the first slide slot 12, the slot 13, the through port 15 and the compression spring 23 cooperate with each other. When the telescopic pregnancy test stick is used, the telescopic rod 3 is pushed forward to separate the limit card 11 from the slot 13 away from the observation window 5. The two connecting rods 10 are subjected to the elastic force moving away from each other through the compression spring 23, so that the limit card 11 is always pressed against the first slide slot 12 and moves in a limited position in the first slide slot 12, thereby improving the stability of the movement of the telescopic rod 3. When the telescopic rod 3 is pushed to the specified position, the limit card 11 is under the action of the compression spring 23. The telescopic rod 3 is fixed by being inserted into the card slot 13 near the observation window 5. The limit card 11 is stably fixed in the card slot 13 by adding a spring structure between the two connecting rods 10, thereby improving the convenience of fixing the telescopic rod 3 after it is extended, and reducing the probability of the telescopic rod 3 retracting after being vibrated or bumped. At the same time, when the telescopic rod 3 is pushed to be extended, the telescopic slot 2, the through port 15 and the first slide slot 12 are used to limit the telescopic rod 3, the connecting block 9 and the limit card 11 respectively, so that the telescopic rod 3 can move stably and be accurately positioned, thereby preventing the telescopic rod 3 from shaking in the housing 1 and causing jamming, thereby improving the user's sense of use;
[0024] Furthermore, the casing 1 is provided with a second slide groove 14 on the outer side of the through opening 15, the second slide groove 14 is connected with the slider 8, a limiting groove 16 is provided at the bottom of the telescopic rod 3, and a limiting block 17 is provided below the telescopic rod 3 of the casing 1, and the limiting block 17 is connected with the limiting groove 16;
[0025] In the specific implementation process, it is worth pointing out that, through the cooperation between the casing 1, the slider 8 and the second slide groove 14, the stroke of the slider 8 is limited by the second slide groove 14, so that the telescopic rod 3 can be accurately telescoped into place, and the stability of the slider 8 when moving is improved. Through the cooperation between the casing 1, the telescopic rod 3, the limiting groove 16 and the limiting block 17, the casing 1 limits the limiting groove 16 of the telescopic rod 3 through the limiting block 17, thereby improving the telescopic stability of the telescopic rod 3, and limiting the telescopic stroke of the telescopic rod 3, ensuring that the telescopic rod 3 is telescoped. The telescopic rod 3 is precisely positioned during the contraction, and the cooperation among the housing 1, the telescopic rod 3, the slider 8, the second slide groove 14, the limiting groove 16 and the limiting block 17, and the limiting between the second slide groove 14 and the slider 8, the limiting groove 16 and the limiting block 17, improves the stability of the telescopic rod 3 during the telescopic movement, and the telescopic stroke of the telescopic rod 3 is limited, so that the telescopic rod 3 can be precisely positioned, thereby improving the accuracy and reliability of the telescopic pregnancy test stick, and avoiding the misalignment of the observation window 5 and the observation port 6 due to the inaccurate position of the telescopic rod 3, thereby affecting the reading of the test result;
[0026] Furthermore, a covering sticker 18 is provided on the top of the casing 1 above the observation window 5, and the covering sticker 18 is used to cover the observation window 5. A sampling groove 19 is provided on the outer side of the sampling hole 4 of the telescopic rod 3, and the sampling groove 19 is used to guide the sampled urine so that the sampled urine accurately enters the sampling hole 4. The sampling groove 19 and the outer side of the observation window 5 are both provided with an indication mark 20, and the indication mark 20 is used to improve the convenience of the telescopic pregnancy test stick, so that the user can master the use of the pregnancy test stick more quickly;
[0027] In the specific implementation process, it is worth pointing out that the covering sticker 18 is used to cover the observation window 5. When the telescopic rod 3 is not pushed out for use, the covering sticker 18 can form a seal on the sampling hole 4 to prevent dust, dirt or other external substances from entering the interior of the pregnancy test stick, thereby maintaining the cleanliness and accuracy of the pregnancy test stick. The sampling groove 19 is used to guide the sampled urine so that the sampled urine accurately enters the sampling hole 4. The indicator mark 20 is used to improve the convenience of the telescopic pregnancy test stick, so that the user can master the use of the pregnancy test stick more quickly.
[0028] Furthermore, anti-skid convex strips 21 are equidistantly arranged on the top of the slider 8, and the anti-skid convex strips 21 are used to increase the friction force on the top of the slider 8;
[0029] In the specific implementation process, it is worth pointing out that the anti-slip convex strip 21 is used to increase the friction force on the top of the slider 8, which can provide better control and stability when using the slider 8;
[0030] Furthermore, anti-skid rubber strips 22 are provided on both sides of the casing 1, and the anti-skid rubber strips 22 are used to improve the grip of the casing 1 by the hand and reduce the risk of the pregnancy test stick falling out of the hand;
[0031] In the specific implementation process, it is worth pointing out that the anti-slip rubber strip 22 is used to improve the grip of the hand on the housing 1 and reduce the risk of the pregnancy test stick falling out of the hand;
[0032] Specifically, when using the telescopic pregnancy test stick, tear off the covering sticker 18, open the observation window 5, push the slider 8 to the side close to the observation window 5, and extend the telescopic rod 3 from the inside of the shell 1 through the connecting block 9. At the same time, the limiting card 11 enters the first sliding groove 12 from the slot 13 away from the observation window 5 for movement. When the slider 8 is pushed to the side close to the observation window 5, the second sliding groove 14 limits the slider 8, the through hole 15 limits the connecting block 9, and the limiting block 17 limits the limiting groove 16. At the same time, the limiting card 11 is inserted into the slot 13 close to the observation window 5 under the action of the compression spring 23 to limit the telescopic rod 3. At the same time, the observation port 6 is aligned with the observation window 5, and the urine sample is collected through the sampling hole 4. The urine sample enters the test strip 7. After waiting for a certain period of time, the test strip 7 produces a color change at the observation port 6, and the color change of the test strip 7 at the observation port 6 is obtained through the observation window 5. After the test result is obtained, the slider 8 is pushed to the side away from the observation window 5 to put the telescopic rod 3 into the sleeve shell 1, and the telescopic pregnancy test stick can be abandoned. Through the cooperation between the sleeve shell 1, the telescopic slot 2, the telescopic rod 3, the slider 8, the connecting block 9, the connecting rod 10, the limit card 11, the first slide slot 12, the slot 13, the through hole 15 and the compression spring 23, and the spring structure is added between the two connecting rods 10, so that the limit card 11 is stably limited and fixed in the slot 13, thereby improving the convenience of fixing the telescopic rod 3 after it is extended, and reducing the probability of the telescopic rod 3 being retracted after being vibrated or bumped. At the same time, when the telescopic rod 3 is pushed to be extended, the telescopic slot 2, the through hole 15 and the first slide slot 12 are used to limit the telescopic rod 3, the connecting block 9 and the limit card 11 respectively, so that the telescopic rod 3 can move stably and be accurately positioned, so as to avoid the telescopic rod 3 shaking in the sleeve shell 1 and causing jamming, thereby improving the user's sense of use.
