[0024] When using, the handle end of the forceps instrument is clamped and positioned by the deep clamping groove 202 on the limiting frame 2, and the other end of the forceps instrument is placed in the high-low groove 301 of the groove plate frame 3 in an inclined manner, the high-low groove 301 is opposite to the deep clamping groove 202 in position, the high-low groove 301 comprises a high groove and a low groove, and is suitable for classifying and placing forceps instruments of different volumes, the deep clamping groove 202 of the limiting frame 2 is lower than the high-low groove 301 of the groove plate frame 3 in position, so that the forceps instrument is placed in an inclined manner, knife clamping grooves 302 are arranged between the high groove and the low groove of the high-low groove 301, shallow clamping grooves 203 are arranged between the deep clamping grooves 202 on the limiting frame 2, and are used for retaining and placing knife instruments, the handle ends of the forceps instruments and the knife instruments are located in the limiting frame 2, and are at the lowest end, which is beneficial to the experimental personnel to take the instruments, the widths of the deep clamping grooves 202, the shallow clamping grooves 203, the knife clamping grooves 302 and the high-low groove 301 are consistent with the thicknesses of the forceps and the knife instruments, the instruments are clamped and retained, the limiting frame 2 has a limiting and supporting effect on the lowest end of the instruments, various instruments are conveniently placed, and this is beneficial to the experimental personnel to conduct experiments in the super clean bench.

[0025] In the embodiment, a plurality of limiting rods 102 are fixedly connected in the sliding slot 101, the limiting frame 2 is slidingly connected on the limiting rods 102 in a penetrating manner, the two sides of the top end of the placing box 1 are each provided with a positioning valve 201, and the screw rod of the positioning valve 201 is threadedly connected to the side plate of the limiting frame 2.

[0026] When using, when the instrument is a short handle instrument, the experimental personnel rotates the positioning valve 201 to release the retaining connection of the limiting frame 2, and then pushes the limiting frame 2 to make the limiting frame 2 slide and displace in the sliding slot 101, so as to shorten the distance between the limiting frame 2 and the groove plate frame 3, and facilitate the short handle instrument to be placed.

[0027] In the embodiment, the tail end of the positioning valve 201 abuts against one side of the placing box 1, a visual window 103 is fixedly connected to one side of the outside of the placing box 1, and a storage groove 4 is formed in the side of the placing box 1 close to the visual window 103.

[0028] During use, the limiting rod 102 limits the movement of the limiting frame 2 to ensure that the deep groove and the high and low groove 301 are on the same horizontal plane to avoid affecting the placement of the equipment. At the same time, the positioning valve 201 is rotated so that the tail end of the positioning valve 201 abuts against the outer wall of the placement box 1 to fix the position of the limiting frame 2.

[0029] In this embodiment, a stepped rack 5 is provided inside the storage slot 4, and several slide rails 402 are fixedly connected to both sides of the inner wall of the storage slot 4, and the other side of the slide rails 402 is fixedly connected to the outside of the storage slot 4.

[0030] In use, the slide rail 402 drives the step rack 5 to move, which facilitates the retrieval and unfolding of the step rack 5. The step rack 5 moves out of the storage slot 4, which is conducive to placing longer test tube instruments on the step rack 5. Experimenters can view the instruments on the step rack 5 through the viewing window 103, which is convenient for finding the instruments.

[0031] In this embodiment, a positive magnet 401 is fixedly connected to the side of the storage slot 4 away from the slot opening, and a negative magnet 504 is fixedly connected to one side of the stepped rack 5. The negative magnet 504 is magnetically connected to the positive magnet 401.

[0032] In use, the tester pushes the step frame 5, and the slide rail 402 is forced to move the step frame 5 into the storage slot 4. This causes the negative magnet 504 on one side of the step frame 5 to approach the positive magnet 401 on the inner wall of the storage slot 4. Through the principle of attraction between opposite poles of magnets, the negative magnet 504 is magnetically attracted to the positive magnet 401, thus fixing the step frame 5 in place and preventing it from sliding out of the storage slot 4 through the slide rail 402, which would affect the handling.

[0033] In this embodiment, a plurality of test tube slots 501 are provided through the top of the stepped rack 5, and a square slot 502 is provided on the back side of the test tube slots 501. The square slot 502 is provided through one side of the top of the stepped rack 5, and a plurality of handle slots 503 are provided on the side of the stepped rack 5 away from the negative magnet 504.

[0034] In use, the experimenter pulls the step rack 5 through the handle groove 503. The step rack 5 moves out of the storage slot 4 via the slide rail 402, releasing the fixed connection between the step rack 5 and the storage slot 4. The step rack 5 has several test tube slots 501 of different sizes, which facilitates the placement of test tubes. At the same time, the square slot 502 on the back side of the test tube slot 501 facilitates the placement of instruments such as stirring rods and tweezers, so as to avoid the lack of instruments affecting the progress of the experiment.

[0035] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: the handle end of the pliers is clamped and limited by the deep clamping groove 202 on the limiting frame 2, while the other end of the pliers is placed at an angle in the high and low grooves 301 of the slotted plate frame 3. The high and low grooves 301 and the deep clamping groove 202 are opposite to each other. The high and low grooves 301 include a high groove and a low groove, which is suitable for classifying and placing pliers of different sizes. The position of the deep clamping groove 202 of the limiting frame 2 is lower than the high and low grooves 301 of the slotted plate frame 3, so that the pliers are placed at an angle. At the same time, a knife clamping groove 302 is opened between the high groove and the low groove of the high and low grooves 301, and a shallow clamping groove 203 is provided between the deep clamping grooves 202 on the limiting frame 2 for fixing the knife. The handle ends of both the knife and the pliers are located in the limiting frame 2, at the lowest position. The design facilitates easy access for laboratory personnel to handle instruments. The widths of the deep clamping groove 202, shallow clamping groove 203, knife clamping groove 302, and high and low grooves 301 are matched to the thickness of the pliers and knives, providing clamping and securing functions for the instruments. This allows for the convenient placement of various instruments and facilitates experiments within the clean bench. In addition to knives and pliers, the bench can accommodate various instruments such as test tubes, stirring rods, tweezers, and puncture needles. Laboratory personnel can pull the stepped shelf 5 using the handle groove 503. The stepped shelf 5 moves out of the storage groove 4 via the slide rail 402, releasing the fixed connection between the stepped shelf 5 and the storage groove 4. The stepped shelf 5 has several test tube slots 501 of different sizes for easy placement of test tubes. At the same time, the square groove 502 on the back of the test tube slots 501 facilitates the placement of stirring rods, tweezers, and other instruments, preventing the lack of instruments from affecting the experimental progress.
