Connecting plates 802 are fixedly connected to the four corners on the left side of the right limiting plate 801. Slide rods 803 for cooperating with the sliding grooves 603 are fixedly connected to the side of the connecting plate 802 close to the sliding groove 603. A pull rod 804 is fixedly connected to the side of the limiting plate 801 away from the connecting plate 802. The side of the pull rod 804 away from the limiting plate 801 penetrates through the mold base body 1 and extends to the outside of the mold base body 1.

[0030] With the above solution: By providing the control mechanism 8, the fixing mechanism 6 can be fixed, which is convenient for the user to use the fixing mechanism 6.

[0031] Reference Figure 3 , one side of the positioning block 4 close to the mold base body 1 is fixedly connected to the mold base body 1, and one side of the positioning block 4 close to the inner wall of the positioning groove 3 contacts the inner wall of the positioning groove 3.

[0032] With the above solution: By providing the positioning block 4, the placing table 2 can be positioned, which is convenient for the user to use the placing table 2.

[0033] Reference Figure 3 , first through holes 9 for cooperating with the fixed blocks 602 are formed in both the front side and the rear side of the inner cavity of the movable groove 5, and a second through hole 10 for cooperating with the pull rod 804 is formed in the right side of the inner cavity of the right movable groove 5.

[0034] With the above solution: By providing the first through holes 9 and the second through holes 10, the fixed blocks 602 and the pull rod 804 can be limited respectively, which is convenient for the user to use the fixed blocks 602 and the pull rod 804.

[0035] Reference Figure 3 And Figure 4 , the middle part of the side of the spring 601 close to the inner wall of the movable groove 5 is fixedly connected to the inner wall of the movable groove 5, and the side of the fixed block 602 close to the inner wall of the fixing groove 7 contacts the inner wall of the fixing groove 7.

[0036] Adopting the above solution: By setting the spring 601, the fixing block 602 can be reset. By setting the fixing block 602 and the fixing groove 7, the placing table 2 can be fixed.

[0037] Reference Figure 3 and Figure 4 , one side of the limiting plate 801 close to the inner wall of the movable groove 5 is in contact with the inner wall of the movable groove 5, one side of the sliding rod 803 close to the inner wall of the sliding groove 603 is in contact with the inner wall of the sliding groove 603, and one side of the pull rod 804 close to the inner wall of the second through hole 10 is in contact with the inner wall of the second through hole 10.

[0039] The working principle of the present utility model:

[0040] During use, the user pulls the pull rod 804, the pull rod 804 drives the limiting plate 801 to move, the limiting plate 801 drives the sliding rod 803 to move through the connecting plate 802, the sliding rod 803 drives the fixing block 602 to enter the inner cavity of the movable groove 5 and squeeze the spring 601. After the user places the placing table 2 into the inner cavity of the mold base body 1 and makes the positioning block 4 enter the inner cavity of the positioning groove 3, the pull rod 804 is released. The force released after the spring 601 is squeezed pushes the fixing block 602 to move in the reverse direction, so that while the fixing block 602 is inserted into the inner cavity of the fixing groove 7, the fixing block 602 drives the limiting plate 801 to move in the reverse direction and reset through the sliding rod 803 and the connecting plate 802, and the use is completed.

[0041] To sum up: For this chemical reagent placing rack, by cooperating with the use of the fixing mechanism 6, the fixing groove 7 and the control mechanism 8, pulling the pull rod 804, the pull rod 804 drives the limiting plate 801 to move, the limiting plate 801 drives the sliding rod 803 to move through the connecting plate 802, the sliding rod 803 drives the fixing block 602 to enter the inner cavity of the movable groove 5 and squeeze the spring 601, which solves the problem that during the long-term use of the placing rack, the surface of the placing rack is easily damaged due to the corrosion of chemical reagents, and the placing table needs to be replaced during maintenance. However, the operation steps for replacing the placing table of the existing placing rack are too cumbersome and the replacement time is too long, affecting the use of the placing rack.
