The hydraulic rod 203 provides power for the movement of the placing plate 3. By controlling the telescopic movement of the hydraulic rod 203, the clamping block 303 can be pushed to move up and down in the sliding groove 202, and then drive the placing plate 3 to adjust the height, making the height adjustment of the placing plate 3 more convenient and accurate, and can meet the height requirements of different experimental operations for the placing plate 3. At the same time, the connection method of the hydraulic rod 203 also ensures that it can stably push the clamping block 303 and the placing plate 3, ensuring that the placing plate 3 will not have accidental movement or shaking during use, enabling the placing plate 3 to be adjusted according to the actual situation, and thus improving the flexibility of the device.

[0026] In the embodiment of the present utility model, two limiting blocks 401 are fixedly installed at the bottom end of the washbasin 4. The two limiting blocks 401 are embedded inside two grooves 302, and the two limiting blocks 401 are in sliding connection with the two grooves 302. Among them, balls 402 are embedded at the bottom of the two limiting blocks 401, and the balls 402 are in movable connection with the limiting blocks 401; two limiting blocks 401 are fixedly installed at the bottom end of the washbasin 4. The limiting blocks 401 are embedded inside the two grooves 302 at the upper end of the placing plate 3, so that the movement of the washbasin 4 in the horizontal direction is restricted to a certain extent. When it is necessary to adjust the position of the washbasin 4, it can be achieved by sliding the position of the limiting blocks 401 in the grooves 302, which improves the flexibility of the position adjustment of the washbasin 4. Balls 402 are embedded at the bottom of the two limiting blocks 401, and the balls 402 are in movable connection with the limiting blocks 401. The balls 402 can reduce the friction between the limiting blocks 401 and the grooves 302, making the washbasin 4 move more smoothly when adjusting the position and reducing the operation difficulty. Secondly, the movable connection mode of the balls 402 enables them to roll freely between the limiting blocks 401 and the grooves 302 to adapt to the sliding requirements in different directions. When adjusting the position of the washbasin 4, the balls 402 can automatically adjust the rolling direction according to the force direction, improving the operation convenience. Finally, the existence of the balls 402 can also reduce the wear of the limiting blocks 401 and the grooves 302, and extend the service life of the placing plate 3 and the washbasin 4.

[0027] In the embodiment of the present utility model, two positioning blocks 501 are fixedly installed at the bottom of the test tube rack 5. The two positioning blocks 501 are embedded inside two grooves 302, and the two positioning blocks 501 are in sliding connection with the two grooves 302; the two positioning blocks 501 fixedly installed at the bottom of the test tube rack 5 mainly play the role of fixing and positioning the test tube rack 5. By embedding the positioning blocks 501 into the two grooves 302 at the upper end of the placing plate 3, the position of the test tube rack 5 on the placing plate 3 can be relatively stable, preventing the test tube rack 5 from moving or shaking unnecessarily during use, and ensuring that the test tubes can be safely placed on the test tube rack 5.

The threaded holes 503 provide multiple installation positions for the support rods 502, and different threaded holes 503 can be selected to install the support rods 502 according to actual needs, so as to adjust the position and spacing of the support rods 502. For example, when placing test tubes of different specifications, the position of the support rods 502 can be adjusted to adapt to the size of the test tubes, ensuring that the test tubes can be stably placed on the test tube rack 5, further improving the applicability of the test tube rack 5, making the test tube rack 5 more flexible and convenient to use, and more convenient when organizing test tubes.

[0029] Working principle: First of all, the box body 1 serves as the basic part. The chute 202 inside the limiting rod 201 of the bracket 2 provides a track for the installation and movement of the placement plate 3. The clamping blocks 303 at both ends of the placement plate 3 are embedded in the chute 202. The height adjustment of the placement plate 3 can be controlled by the hydraulic rod 203 in the chute 202. The experimenter can adjust the placement plate 3 to a suitable height by using the hydraulic rod 203 according to different experimental operation requirements. A washbasin 4 and a test tube rack 5 are arranged on the placement plate 3. The bottom end of the washbasin 4 penetrates through the limiting groove 301 of the placement plate 3, and the protruding part at the bottom can be embedded into the card slot 101 at the upper end of the box body 1 for limiting as needed. When it is necessary to adjust the position of the washbasin 4, the limiting block 401 at the bottom of the washbasin 4 slides in the groove 302 at the upper end of the placement plate 3. The ball 402 at the bottom of the limiting block 401 reduces the friction force, making the position adjustment of the washbasin 4 smoother. The positioning block 501 at the bottom of the test tube rack 5 is embedded in the groove 302 of the placement plate 3 to realize the positioning and stable placement of the test tube rack 5. The sliding connection between the positioning block 501 and the groove 302 enables the test tube rack 5 to be flexibly adjusted according to experimental needs. The support rods 502 at the upper end of the test tube rack 5 are connected by threads, and different threaded holes 503 can be selected for installation according to different specifications of test tubes to adjust the position and spacing of the support rods 502 to ensure that the test tubes can be stably placed on the test tube rack 5. During the experiment, the experimenter can conveniently clean hands and experimental instruments in the washbasin 4, and the test tubes are neatly placed on the test tube rack 5 and kept stable by the action of the support rods 502 and the positioning blocks 501. The box door 102 on the side of the box body 1 can be opened and closed, facilitating the access to experimental supplies and equipment, and thus making the experimenter more convenient during the experiment.
