The ratchet screwdriver is characterized in that a power supply and a light-emitting element are arranged in the ratchet cover, a control switch is arranged on the side of the ratchet cover, a light transmitting hole for light rays to penetrate through is formed in the upper end of the ratchet cover, and the light-emitting element is electrically connected with the power supply and the control switch through wires to form an illuminating circuit. The power supply and the light-emitting element are arranged in the ratchet cover, and therefore the ratchet screwdriver has the illumination function; in the use process, an LED lamp can be turned on or turned off only by pushing the control switch leftward or rightward; the illumination effect is good due to the fact that the illumination light rays face right towards the tool bit of the ratchet screwdriver. The ratchet screwdriver is simple in structure and convenient to assemble, and has the illumination function and high practicability.
Description
Technical field
The utility model relates to a kind of screwdriver, specifically a kind of ratchet screwdriver with illumination functions.
Background technology
Screwdriver is as a kind of conventional handware, and for slack adjuster, existing screwdriver generally includes handle, knife bar and cutter head, and user drives knife bar and cutter head to rotate by turning handle, thereby cutter head drives screw turns to carry out the degree of tightness of screw.But such screwdriver rotates by manpower completely, use relatively effort and direction also wayward, in rotation process, may cause convolution to make to use more inconvenient.
In order to address this problem, there is much can realizing the ratchet screwdriver of one direction idle running, ratchet screwdriver uses laborsaving convenience, but often need flashlight etc. to carry out floor light tear the turn of the screw open in the darker environment of light time, if the words of people's operation, not only can increase operating personnel's difficulty, and illuminating ray also can block by the hand in when operation, illuminating effect is not very good.Also there is having in the market the screwdriver of illumination functions, as the patent No. Chinese utility model patent " a kind of screwdriver " that is CN201310296626.7, comprise handle of a knife, knife bar and cutter head, the inside of described handle of a knife is provided with battery, the top of described handle of a knife is provided with switch, the center of described cutter head is embedded with a LED lamp pearl, battery by switch to LED lamp pearl powered lighting.In said structure, be that LED lamp pearl has been installed on cutter head, convenient illumination while making to operate.But it is very inconvenient that lamp pearl is installed on cutter head, and dismounting is also cumbersome, and the ratchet screwdriver in addition with illumination functions yet there are no report.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of rational in infrastructure and have a ratchet screwdriver of illumination functions for the above-mentioned state of the art.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of ratchet screwdriver, comprise pawl seat, pawl base and ratchet casing, the front portion of described pawl seat is the jack that connects outside driver bit, the outer surface at rear portion is ratchet, on described pawl base, be axially arranged with the through hole that can insert for pawl seat, pawl base is set on pawl seat, ratchet casing is nested with the front portion at pawl base, with pawl base rotation location, the rear end of pawl base is connected with screw driver handle, it is characterized in that: in described ratchet casing, be provided with power supply and light-emitting component, the sidepiece of ratchet casing is provided with gauge tap, the upper end of ratchet casing is provided with the loophole passing through for light, light-emitting component is by wiring and power supply, gauge tap is electrically connected and forms lighting loop.
As improvement, described ratchet casing is made up of outer collar and upper cover two parts, the lower end of outer collar is nested with on pawl base, upper cover is arranged on the upper surface of outer collar and is involutory with outer collar, on the upper surface of outer collar, be provided with power supply source, the mounting groove that light-emitting component and wiring are inserted and located, the sidepiece of outer collar is provided with the breach that stretches out and stir for gauge tap, power supply, light-emitting component and gauge tap are arranged in outer collar involutory fixing by upper cover, be provided with corresponding with the through hole centre bore inserting for pawl seat and the corresponding loophole with luminous element position upper covering.
As improvement, the upper surface of described outer collar is provided with some joint pins, above covers and offers corresponding connecting hole, by screw, upper cover and outer collar is connected and fixed.
Improve, the left and right sides of the lateral notch of described outer collar is provided with concavo-convex switch mark again.
Improve, described power supply is button cell again, and light-emitting component is a LED lamp pearl.
Compared with prior art, the utility model has the advantage of: power supply and light-emitting component are set in ratchet casing, make ratchet screwdriver there is the function of illumination, while use in the darker environment of light, as long as promoting gauge tap, left and right just LED lamp can be opened or closed, and the just cutter head to ratchet screwdriver of the illuminating ray of LED lamp, can not be blocked, illuminating effect is fine.The utility model is simple in structure, easy to assembly, and has illumination functions, has very strong Practical Performance.
