[0009] By adopting the above technical solution, through the arrangement of the universal wheel and the through slot, the universal wheel facilitates the movement of the placement rack, and the through slot facilitates the movement of the universal wheel when the second bottom plate is stored inside the first bottom plate.

[0010] The utility model is further configured as follows: two hidden grooves are arranged inside the connecting plate, and the fixing bolts are located inside the hidden grooves.

[0011] The above technical solution is adopted to hide the fixing bolts by setting the hidden groove, so as to prevent the fixing bolts from blocking the bracket from being stored in the storage groove.

[0012] The utility model is further configured as follows: a magnet is fixedly connected inside the connecting plate, and one side of the bracket is fixedly connected to two iron sheets adsorbed by the magnet.

[0013] By adopting the above technical solution, through the arrangement of magnets and iron sheets, the magnets are used to adsorb the iron sheets, thereby limiting the position of the bracket after it is vertically erected.

[0014] The utility model is further configured as follows: the lower surfaces of the two universal wheels are on the same horizontal line.

[0015] By adopting the above technical solution, the lower surfaces of the two universal wheels are flush, which can ensure the stability of the placement rack when it moves.

[0016] In summary, the utility model has the following beneficial effects:

[0017] The utility model can be used to place various experimental instruments and equipment by arranging a rotatable bracket, and the connecting plate can store the bracket, and cooperate with the bottom plate one that can store the bottom plate two. When the placement rack is not in use, the bracket can be stored in a vertical state, and the bottom plate two can be stored inside the bottom plate one, thereby reducing the floor space required for the placement rack; and by arranging two fixing bolts inside the connecting plate and opening a plurality of thread grooves two inside the back plate for use with the thread grooves two, the position of the connecting plate can be adjusted accordingly according to the height of the experimental instruments and equipment, so that it can adapt to the placement of instruments and equipment of different sizes, thereby improving its flexibility and practicality.
