[0035] As shown in Figure 2 and Figure 4 , the supporting mechanism comprises a cross beam 5 arranged between the two side plates 3, a supporting beam 6 is arranged at the top center of the cross beam 5, and one end of the supporting beam 6 away from the cross beam 5 is fixedly connected to the inner side surface of the instrument desk body 1.

[0036] When the instrument desk body 1 is subjected to an external force, the deformation resistance of the instrument desk body 1 can be greatly improved by cooperation of the cross beam 5 and the supporting beam 6, which is beneficial to actual use.

[0037] As shown in Figure 4 , the two opposite side surfaces of the supporting beam 6 are fixedly connected with a reinforcing rib 7, one end of the reinforcing rib 7 away from the supporting beam 6 is fixedly connected with the cross beam 5, and the two reinforcing ribs 7 are symmetrically arranged about the central axis of the supporting beam 6.
