step two: if the position of the fixing seat 212 needs to be adjusted, the clamping rotating piece 213 is rotated to separate the clamping rotating piece from the operating table 4, then the fixing seat 212 is lifted upwards to separate the two locking blocks 214 from the clamping positions, at this time, the fixing seat 212 can be horizontally moved to move to the required position, then the fixing seat 212 is put down to clamp the two locking blocks 214 with the clamping positions at the corresponding positions, and then the clamping rotating piece 213 is rotated again to clamp the bottom of the operating table 4 to keep the fixing seat 212 fixed, so that the whole guide rail 211 is synchronously kept fixed;
step three: when the power supply body 1 is used, firstly, the connecting piece 31 is pulled to drive the two baffles 321 to slide on the outer side of the power supply body 1, so that the heat dissipation port is gradually opened, the extruded parts of the cushion blocks 324 gradually disappear while the baffles 321 move, at the moment, under the action of the elastic force of the first spring 325, the outer side of the dust absorption rotating piece 322 is finally tightly attached to the heat dissipation port and moves along with the baffles 321 to synchronously rotate on the outer side of the heat dissipation port, dust adsorbed on the heat dissipation port can be adsorbed on the surface of the dust absorption rotating piece until the baffles 321 are completely unfolded, and the dust absorption rotating piece 322 is just subjected to the extrusion action of the cushion blocks 324 on the other side to be separated from the outer side of the power supply body 1, so that the adsorbed dust is prevented from being adsorbed on the power supply body 1;
step four: at this moment, the thermovent of power supply body 1 both sides is opened completely, then through pulling clearance scraper 323 downwards for clearance scraper 323 is inboard with inhale grey and change the piece 322 and paste the laminating outward, and slide down in its outside, can clear up the absorbent back of its outside, realizes changeing the clearance of piece 322 surface dust to inhaling grey, after power supply body 1 used up, only need with connecting piece 31 pull back, make baffle 321 with the thermovent shutoff on can.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes, which are made by using the contents of the present specification and the accompanying drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
