The invention discloses an ultra-low ripple switching power supply with a protection mechanism. The other end of a first telescopic rod is connected with the top of a steel block, the outer side of the steel block is hinged to the top of a second telescopic rod, the bottom of the second telescopic rod is hinged to the top of an inner housing, a power supply body is arranged on the inner side of the inner housing, the inner side of an outer housing is connected with the outer side of the inner housing through a first spring, heat dissipating fins are equidistantly arranged on the top of the power supply body, a fan port is formed in one side of the inner housing, and a fan is arranged in the fan port. The inner housing is lifted and pulled by the power supply through the first telescopic rod and the second telescopic rod, so that the inner housing is suspended in the air, shock absorbing of a horizontal plane is conducted on the inner housing through the first spring, the shock-absorbing protection effect of the power supply body is better, by the arrangement of the outer housing and the inner housing, better protection on the power supply body can be achieved by the inner and outerhousings, and the bumping and damaging of the power supply body are effectively prevented.
