A user holds the handle 2 by hand, the driving motor 3 is started, the transmission shaft 4 is rotated, the rotation of the transmission shaft 4 drives the drill rod 5 to rotate through the connector 6, drilling is realized, during the period, the rotation of the transmission shaft 4 drives the rotating ring 8 to rotate, the rotation of the rotating ring 8 drives the moving ring 9 to rotate through the fixed block 14, the supporting rod 12, the sliding block 11 and the connecting rod 10 in sequence, the sliding block 11 moves towards the direction far away from the transmission shaft 4 under the action of centrifugal force, the first spring 13 is compressed, the movement of the sliding block 11 drives the moving ring 9 to move towards the direction close to the drill rod 5 through the connecting rod 10, the movement of the moving ring 9 pushes the moving rod 19 to realize synchronous movement through the balls 18, the sealing plate 17 is separated from the main body 1, in addition, the rotation of the transmission shaft 4 also drives the fan blades 7 to rotate, thereby the air in the main body 1 is discharged from the, dust generated during drilling can enter the air inlet under the action of air flow, the dust is trapped through the first filter screen 15, the function of collecting the dust can be realized, the connecting line 24 is loosened by the movement of the moving rod 19, the moving plate 23 is moved towards the direction close to the protection plate 21 under the elastic action of the second spring 26, the moving plate 23 is moved to drive the illuminating lamp 20 to move to the outside of the main body 1 through the push rod 28, and then the illuminating lamp 20 is lightened to realize illumination;

after drilling is finished and transmission shaft 4 stall, make slider 11 restore to the throne under the elastic action of first spring 13, the restoration of slider 11 drives shift ring 9 through connecting rod 10 and realizes restoring to the throne, the restoration of shift ring 9 loops through ball 18 and carriage release lever 19 and drives closing plate 17 and restore to the throne, make closing plate 17 support and lean on with first filter screen 15, glue through closing plate 17 can make the dust adhesion on first filter screen 15 on the closing plate 17, can so that clear away the function of dust on first filter screen 15, prevent that first filter screen 15 from blockking up, and, the restoration of carriage release lever 19 realizes restoring to the throne through connecting wire 24 pulling movable plate 23, the restoration of movable plate 23 drives light 20 through push rod 28 and realizes restoring to the throne, make second spring 26 tensile simultaneously, and make guard plate 21 cover on the through-hole, the effect of protection light 20 has been played.

Compared with the prior art, this electric tool with illumination function has realized the function of illumination through lighting mechanism, compare with current lighting mechanism, this lighting mechanism has still played the function that light 20 accomodates through the removal of drive light 20, set up light 20 in the through-hole simultaneously, also can play the effect of protection light 20, the practicality is stronger, moreover, still realize the function of collecting the dust that produces during drilling through complementary unit, compare with current complementary unit, this complementary unit can also clear away the function of dust on the first filter screen 15, prevent that first filter screen 15 from blockking up, and, through the circulation of air and the main part 1 outer air in main part 1, can promote the radiating effect of main part 1, the practicality is stronger.

In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
