The invention discloses a maintenance platform with a clamping structure and a dust removal device for computer maintenance. The maintenance platform comprises a clamping mechanism, a first air pump, a bearing frame, a second motor and a motor, a second air pump is fixed on one side of the top in a bearing platform, and a dust collector is fixed on the other side of the top in the bearing platform. According to the maintenance platform with the clamping structures and the dust removal device for computer maintenance, after a computer is placed on the bearing table, four clamping plates get close to one another, the computer is conveniently clamped and fixed, then the computer can be maintained through a maintenance tool, meanwhile, the computer can rotate along with a rotary table, maintenance operation is more convenient, and before the computer is maintained, if too much dust is found in the computer, an illuminating lamp is rotated away from the position below an isolation hood, then the isolation hood moves downwards and covers the outer side of the computer, then an air blowing channel blows air downwards and rotates at the same time, meanwhile, the computer rotates along with the rotary table, comprehensive dust removal operation is facilitated, and blown-away dust can be sucked away by the dust suction channel in time.
