[0026] The outer sides of the two limit columns 14 are slidably connected to two limit rings 15, the top of the limit ring 15 is in contact with the bottom end of the experimental table 16, the inner side of the limit ring 15 is provided with an inner groove 22, and the outer side of the limit column 14 is provided with two clamping strips 21, the outer side of the clamping strip 21 is engaged with the inner wall of the inner groove 22, the outer side of the limit column 14 is slidably connected to the experimental table 16, the outer side of the experimental table 16 is slidably connected to the inner wall of the bench frame 12, the outer side of the limit column 14 is slidably connected to the clamping table 17, and the bottom end of the base table 1 is fixedly connected to the supporting mechanism.

[0027] Specifically, the base table 1 is placed at a suitable position, and then the stand frame 12 is rotated, and the stand frame 12 is rotated by the sliding rod 13, so that the stand frame 12 as a whole is vertical relative to the inner cavity 11 of the base table 1, and then the stand frame 12 is pressed, so that the rotating cavity 19 opened inside the stand frame 12 slides relative to the sliding rod 13, so that the stand frame 12 is sunk into the slot 18;

[0028] Then, insert the card table 17 into the limiting column 14 until the bottom end of the card table 17 slides into the inside of the card slot 18 and is engaged with the card slot 18 together with the stand frame 12. Insert the two limiting rings 15 into the limiting columns 14 respectively and move them to the unset position of the card strip 21 on the limiting column 14. Then, rotate the limiting ring 15 so that the limiting ring 15 is fixed on the limiting column 14. Then, insert the laboratory table 16 from the limiting column 14 to the top of the limiting ring 15, so that the laboratory table 16 is fixed as a whole. Then, repeat the above operation to fix the other laboratory table 16.

[0029] Reference Figure 3 and Figure 4 The supporting mechanism includes a power rod 8, one end of the power rod 8 is fixedly connected to a handle 10, the outer side of the handle 10 is provided with anti-slip grooves, the outer side of the power rod 8 is rotatably connected to the inner side of the base platform 1, the outer side of the power rod 8 is fixedly connected to two power bevel gears 9, the outer sides of the two power bevel gears 9 are respectively meshed with the outer sides of the driven bevel gears 6 at the corresponding positions, the inside of the base platform 1 is fixedly connected to two fixed blocks 7, the outsides of the two fixed blocks 7 are both rotatably connected to a two-way threaded rod 5, one end of the two-way threaded rod 5 is fixedly connected to the driven bevel gear 6, the outer side of the two-way threaded rod 5 is threadedly connected to two threaded blocks 4, the outer side of the threaded block 4 is rotatably connected to a side rod 3, and the four corners of the bottom end of the base platform 1 are provided with recovery chambers 20, the inside of the recovery chamber 20 is rotatably connected to a foot support 2, and the outer side of the foot support 2 is rotatably connected to one end of the side rod 3.

[0030] Specifically, by turning the handle 10, the two power bevel gears 9 on the power rod 8 are rotated through the fixed connection between the power rod 8 and the handle 10, and then the driven bevel gear 6 that is meshed with the two power bevel gears 9 will rotate along with the power bevel gears 9, thereby driving the corresponding two-way threaded rods 5 respectively, and the thread blocks 4 provided on the two symmetrical threads of the two-way threaded rod 5 will not rotate themselves due to the sliding connection with the base platform 1, but will relatively approach or move away with the rotation of the two-way threaded rod 5, and then the side rod 3 rotatably connected to the thread block 4 will pull the foot support 2, so that the foot support 2 will be extended or retracted, thereby realizing a more convenient assembly of the experimental workbench.

[0031] Working principle: When using this design, the staff first needs to hold up the base table 1 and turn the handle 10 at the same time, so that the handle 10 drives the power bevel gear 9 through the power rod 8, and then the driven bevel gear 6 meshing with the power bevel gear 9 will rotate successively, thereby driving the two-way threaded rod 5 to rotate. At this time, the threaded blocks 4 at the symmetrical position of the two-way threaded rod 5 will move relatively, thereby driving the side rod 3 rotatably connected to it, and the side rod 3 will push the other end of the foot support 2 rotatably connected to it, until the foot support 2 is recovered to the recovery chamber 20, thereby completing the support recovery of the entire experimental workbench, thereby realizing the convenience of installation and disassembly of the experimental workbench, and facilitating the experimental workbench. When changing the position, the movement is required, and then the laboratory table 16 above the laboratory workbench is removed from the limiting column 14, and then the limiting ring 15 is rotated to engage with the card strip 21, so that the limiting ring 15 can slide on the limiting column 14, and then the limiting ring 15 is removed, and the laboratory table 16 and the limiting ring 15 are placed in the inner cavity 11, and the card table 17 is also removed from the limiting column 14, and then the stand frame 12 is pulled up to disengage it from the card slot 18 and then the stand frame 12 is lowered to cover the inner cavity 11, thereby completing the recovery of the laboratory workbench, which disassembles and recycles the entire laboratory workbench, and the above process is reversed at the same time, so that the laboratory workbench can be assembled.
