The specific embodiment

Embodiment 1:

As Fig. 2 A and shown in Figure 3, a kind of electric drill of tool illumination functions is by housing 1, motor 2, turn to key 3, main shaft 4, drill chuck 5, electric drill switch 6, base 7, supply unit 8, electronic component 9, lead 10 and lighting device 11 to form.Wherein, supply unit 8 uses rechargeable battery 81, and charging inlet 82 is installed; Lighting device 11 is the overhead flip-shell, form by the illuminating lamp 111 of the lamp box 113 of tool resilient contact 12 and the lamp cassette holder 114 of tool ring-type contact 13, resilient contact switch 112 is made up of resilient contact 12 and ring-type contact 13, its concrete structure and operation principle are as follows: resilient contact switch 112 is made up of a pair of resilient contact 12 of both sides, lamp box 113 below and the ring-type contact 13 of lamp cassette holder 114 rear ends, and resilient contact 12 is made of corresponding pair of conductive body 121 and a pair of insulator 122; The both sides, rear end of lamp cassette holder 114, one corresponding ring contact 13 is respectively arranged, also be made of corresponding pair of conductive body 131 and a pair of insulator 132, the internal diameter size of the outside dimension of resilient contact 12 and ring-type contact 13 is in active relationship, and contacts closely each other and can rotate freely.When lamp box 113 is installed on the lamp cassette holder 114, the a pair of resilient contact 12 of both sides, lamp box 113 below, just can utilize its elastic force, suppress in the ring-type contact of lamp cassette holder 114 into, at this moment this resilient contact 12 had both played axle, make lamp box 113 can on lamp cassette holder 114, do the rotation of 90 degree, play switch again.Because the insulator 132 of the ring-type contact 13 of the insulator 122 on the resilient contact 12 and the installation of electric conductor 121 and lamp cassette holder 114 rear ends and the installation site of electric conductor 131, hold up when opening at lamp box 113, just in time corresponding, so power turn-on, illuminating lamp 111 bright (shown in Figure 11 L), when lamp box 113 was depressed closure, both electric conductors (121,131) were just in time opposite with insulator (122,132), make dump, illuminating lamp extinguishes (shown in Figure 11 K).
