The invention discloses a portable miniature micro-curved suction cup type fixing seat, which comprises a suction cup adsorption mechanism, an electromagnet locking mechanism, an air pressure detection and stabilizing device and a fixing and guiding mechanism. Threads are processed on the inner side of the shell on the fixing seat, so that the micro repair equipment can be fixed on the fixing seat. The suction cup in the suction cup adsorption mechanism is composed of a suction cup and a universal joint. When the skin is a curved surface, the universal joint rotates to ensure the complete fit of the suction cup and the curved surface. After the suction cup is adsorbed on the skin, the air pressure and the detection device Working, it can detect whether the air pressure in the shell reaches the design value. The air pressure detection and stabilization device is installed at the vent hole. When the solenoid valve is not energized, the air circuit is normally open. When working, if the air pressure in the shell is lower than the design value, the air in the shell is drawn out of the shell. When the air pressure in the shell reaches When the set value is set, the solenoid valve is energized, the air circuit remains normally closed, and the solenoid locking mechanism works. When the electromagnet locking mechanism is working, the electromagnet is energized to generate magnetism, which attracts the magnet on the lever, thereby driving the lever to rotate, and the clamping block tightens the support rod. After the work of the sucker-type fixing seat is completed, the electromagnet is powered off, the solenoid valve is powered on, the gas enters the shell cavity through the solenoid valve, and the support rod is reset to complete a working cycle. The beneficial effect of the invention is that a portable micro-curved surface fixing base is provided for the miniature restoration equipment, and the restoration accuracy of the miniature restoration equipment is improved.
