Pressure sensors are mounted on outer sides of the side panels (10), such that, when one side panel (10) is hit with an external collision force, the pressure sensor receives a signal; upon determining which side panel (10) has been hit, the cylinder (17) on one side is correspondingly controlled to accelerate and push a thrust force block (25) against a slanted surface (26) of a force bearing block (27), so that the force bearing block (27) drives the force counteracting plate (18) to move quickly toward the side panel (10) which has been hit, and to collide with said side panel (10) so as to internally counteract the external collision force on said side panel (10). The cabinet enjoys desirable anti-collision results on the side panels (10) thereof.
