The partition frame 3 arranged on the convenient disassembly frame 2 is cross-shaped, and the end of the cross-shaped frame is plugged into the plug hole 12 through a locking mechanism, so as to realize the disassembly and installation of the convenient disassembly frame 2.

[0030] like Figure 3 As shown, a circular groove 31 and a groove 32 are provided on one side surface of the partition frame 3 located inside the training operation table housing 1. Preferably, the circular groove 31 is arranged at the center of the cross, and the groove 32 is arranged in the four sides of the cross.

[0038] After the disassembly frame 2 is installed on the side of the training operating table shell 1, during the training process, the motor 52 is turned on to drive the rotating shaft 53 to rotate, and the rotating shaft 53 drives the cooling fan 54 to rotate, so that the hot air in the training operating table shell 1 is discharged from the filter 4. During this process, the rotating shaft 53 passes through the rotating rod 61 and drives the cleaning brush 55 to rotate. The cleaning brush 55 cleans the surface of the filter 4 to prevent the filter 4 from being blocked and affecting the heat dissipation effect.
