Abstract

A lighting screw driver comprises a screw driver head (1) and a handle (6). The lighting screw driver is characterized in that a sealing lampshade (2) is placed in the front of the handle (6), a luminous diode (3) connected with a conducting wire (4) is tightly fixed at the front end of the handle (6) inside the sealing lampshade (2), a seal switch (5) and an electron (7) are sequentially fittingly installed on the conducting wire (4), and conductive springs (8), seal screws (9), conductive screws (10), conductive screw threads (11) and an insulation electron base (12) are sequentially disposed inside the rear end of the handle (6). The lighting screw driver meets using requirement and has strong striking-resistant ability. Moreover, lighting and the function of the screw driver are perfectly integrated into a whole, the largest range and brightness of lighting are same as a normal LED flashing light, and the lighting screw driver resolves the fatal problem of short service life when used in severe environment.

Description

Screwdriver capable of illuminating

Technical field

The utility model relates to a kind of screwdriver, is specifically related to a kind of screwdriver capable of illuminating.

Background technology

Screwdriver is a kind of instrument commonly used, and easy to use, working range is extensive.Influence use but general existing screwdriver does not see in the dark, particularly in the place that light source be difficult for to arrive, for example some are narrow local and when using at night, all can influence using and operating of screwdriver.

Notification number: CN2090308, the Chinese patent literature of the day for announcing: 1991.12.11 has been announced a kind of " screwdriver capable of illuminating ", discloses a kind of screwdriver that has lighting device, it is at optically focused miniature bulb of the anterior installation of existing screwdriver handgrip; And handgrip made hollow type, the baby battery of packing into is ganged up with lead then as power supply, adorns a switch at movable bonnet and controls, and can throw light under the condition of dim light, carries out the helical screw operation easily.Notification number: CN2330458, the Chinese patent literature of the day for announcing: 1999.07.28 has been announced a kind of " but screwdriver capable of illuminating ", but discloses a kind of screwdriver capable of illuminating, forms by the bar head with tail, the bar head is fixed on a tail front end.Have a cylindrical cavity in its tail, adorn dry cell in the inner chamber, the position that the inner chamber front end is avoided the bar head has a perforation forward, adorn bulb in the perforation, be stamped bonnet at intracavity posterior end, adorn goring push spring in the bonnet, electric loop is housed in flakes or line and switch on intracavity sidewall.This screwdriver both can have been twisted and turned round screw, can throw light on again, special formula just twists at the dark place and turn round screw.But the used battery of above-mentioned two utility models is bulky, cause the cavity of handle inside too big, and the anti-fight that causes is poor, and torsion is not enough, and the quantity of battery causes power supply persistence deficiency less in addition, and light source disperses to cause problems such as spotlight effect is bad.

Summary of the invention

The purpose of this utility model is shortcomings such as, power shortage poor at existing screwdriver capable of illuminating torsion, illuminating effect difference, provides that a kind of torsion is strong, the screwdriver capable of illuminating of electric power foot, good illumination effect.

The purpose of this utility model realizes by following technological means: screwdriver capable of illuminating, comprise driver bit and handle of a knife, the front of described handle of a knife is provided with sealed lamp shade, the inside of sealed lamp shade, it is the front end of handle of a knife, closely be set with light emitting diode, be connected with lead on the light emitting diode, also assemble successively on the lead and be connected with enclosed switch and electronics, in the inside, rear end of handle of a knife, also be disposed with power spring, sealed screw, conduction screw, conduction screw thread, insulated electro stroma.

Described light emitting diode is that the center on average is provided with round driver bit.

Described lead and handle of a knife cast are set to integrative-structure.

Described sealed lamp shade, power spring, sealed screw, conduction screw, conduction screw thread, insulated electro stroma all are set to enclosed water-proof structure.

Compared with prior art, this screwdriver capable of illuminating has following tangible advantage: 1, the conduction screw all is assemblied in the inside in the handle of a knife and occupies very little space and can satisfy user demand to reach the torsion of guaranteeing screwdriver, anti-strike ability is strong, does not influence the original serviceability of screwdriver when increasing illumination functions.2, do not need to pull out driver bit and just can throw light on, the function of illumination and screwdriver ideally is combined into one; The maximum magnitude of illumination is identical with normal LED torch with luminosity; Combine the water resistance that has increased it.3, solved the light source of existing screwdriver capable of illuminating in adverse circumstances extremely short fatal problem in following service life, light emitting diode in use can not damage because of dropping, collide or impact the handle of a knife rear portion, electric power can be supplied with lastingly, has overcome dark or night in the long-time relatively difficulty of dark situation work.

Description of drawings

Fig. 1 is the structural representation of this screwdriver capable of illuminating;

Among the figure, 1, driver bit, 2, sealed lamp shade, 3, light emitting diode, 4, lead, 5, enclosed switch, 6, the screwdriver handle of a knife, 7, electronics, 8, power spring, 9, sealed screw, 10, the conduction screw, 11, the conduction screw thread, 12, the electronics seat of insulation.

The specific embodiment

Below in conjunction with the description of drawings and the specific embodiment the utility model is described in further detail:

Screwdriver capable of illuminating as shown in Figure 1, comprise driver bit 1 and handle of a knife 6, the front of described handle of a knife 6 is provided with sealed lamp shade 2, the inside of sealed lamp shade 2, it is the front end of handle of a knife 6, closely be set with light emitting diode 3, described light emitting diode 3 is that the center on average is provided with round driver bit; Be connected with lead 4 on the light emitting diode 3, described lead 4 and handle of a knife 6 cast are set to integrative-structure; Also assemble successively on the lead 4 and be connected with enclosed switch 5 and electronics 7,, also be disposed with power spring 8, sealed screw 9, conduction screw 10, conduction screw thread 11, insulated electro stroma 12 in the inside, rear end of handle of a knife 6.

Described sealed lamp shade 2, power spring 8, sealed screw 9, conduction screw 10, conduction screw thread 11, insulated electro stroma 12 all are set to enclosed water-proof structure.

This screwdriver capable of illuminating is applicable under the more weak environment of light such as dark or night, allows the user can dismantle and keep in repair the machinery equipment of needs more easily.In the environment of dark, turn on the power switch, just can conveniently use with a hand, carry out other back work thereby can vacate the another hand.Even in overcast and rainy moist environment, also can normally use this screwdriver capable of illuminating, and can the company's of causing electricity etc. problem.
