Summary of the invention

The present invention is directed to above problem, provide a kind of delicate structure, occupation mode easy, the retractable screwdriver that operating personnel can be thrown light on when utilizing screwdriver that the screw on equipment is dismantled or installed.

Technical scheme of the present invention is: comprise handle of a knife and some cutter heads, described handle of a knife top offers slot, some described cutter heads bottom is provided with the grafting core with described slot adaptation, and described screwdriver also comprises illuminator, and described illuminator comprises controlling organization, power supply and light source;

Described light source is located on the end face of described handle of a knife, and described power supply is located in described handle of a knife, and described controlling organization comprises spring and the push switch that is located at described slot bottom land, and described push switch is serially connected between described power supply and light source.

Described light source ringwise and annular inner ring be provided with light barrier.

In use, operating personnel, when utilizing screwdriver that the screw on equipment is dismantled or installed, while firmly pressing to screw place, can trigger push switch by cutter head in the present invention, thereby some bright light source plays effective illuminating effect.Meanwhile, when screwdriver is idle, cutter head can reset under the effect of spring, thereby has avoided the waste of resource, the service life of the power supply effectively extending.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention;

In figure, 1 is handle of a knife, the 2nd, and cutter head, the 3rd, illuminator, the 31st, light source, the 310th, light barrier, the 32nd, controlling organization, the 321st, spring, the 322nd, push switch, the 33rd, power supply.

The specific embodiment

The present invention as shown in Figure 1, comprise handle of a knife 1 and some cutter heads 2, described handle of a knife 1 top offers slot, and some described cutter heads 2 bottoms are provided with the grafting core with described slot adaptation, described screwdriver also comprises illuminator 3, and described illuminator 3 comprises controlling organization 32, power supply 33 and light source 31;

Described light source 31 is located on the end face of described handle of a knife 1, described power supply 33 is located in described handle of a knife 1, described controlling organization 32 comprises spring 321 and the push switch 322 that is located at described slot bottom land, and described push switch 322 is serially connected between described power supply 33 and light source 31.Like this, operating personnel, when utilizing screwdriver that the screw on equipment is dismantled or installed, while firmly pressing to screw place, can trigger push switch by cutter head, thereby some bright light source plays effective illuminating effect.Meanwhile, when screwdriver is idle, cutter head can reset under the effect of spring, thereby has avoided the waste of resource, the service life of the power supply effectively extending.

Described light source 31 ringwise and annular inner ring be provided with light barrier 310.Make light source can carry out wide angle irradiation, on annular inner ring, set up light barrier, thereby avoided light source direct irradiation on screw, thereby cause operating personnel dazzle and dazzle the eyes simultaneously.
