The present invention relates to a screwdriver, and in particular to a screwdriver capable of illuminating at a screwdriver head.

Generally, when using a screwdriver to remove the screws in a dark place, the user must hold the flashlight or wear a lighting device on the body to perform the group unloading screw operation, which causes troubles and inconveniences in use.

In order to solve the above problems, some manufacturers have begun to design a screwdriver with an auxiliary lighting function, such as a screwdriver with an illumination function disclosed in the Patent No. M274206 of the Republic of China, the plunger of which is inserted into the shaft of a handle. The axial ends of the handle are arranged in front and rear openings, and a circuit board containing a plurality of light-emitting diodes is disposed in the front opening, and a light-transmissive cover disposed at the front end of the light-emitting diode is disposed. And a front cover which is located at the front open end; a battery holder including a battery and a push switch, and a back cover which must be located at the rear open end are sequentially disposed in the rear opening of the handle; the switch, the battery, the circuit board and The light-emitting diodes form an electrical connection, so that the light-emitting diodes emit light in front, and are suitable for unloading screws in case of insufficient ambient light.

Referring to FIG. 1, since the illumination source 61 of the above-mentioned screwdriver 6 is disposed at the handle 60, the light diverging during illumination can only be illuminated. When the surface of the object 7 is used for unloading the in-line screw 9, the divergent light cannot be effectively illuminated into the hole 8 to achieve clear illumination.

Therefore, the object of the present invention is to provide a light-emitting diode (Light Emitting Diode) screwdriver.

Therefore, the novel light guiding type LED screwdriver comprises a screwdriver, an LED lighting unit, and a light guiding unit.

The screwdriver includes a grip and a lever member extending outwardly from an end face of the grip along the axis of the grip. The rod has a driver end that is remote from the grip.

The LED lighting unit is disposed in the handle and includes at least one LED lamp disposed adjacent to the bar member, and a power supply unit electrically connected to the LED lamp.

The light guiding unit is disposed on the rod and is configured to guide the light of the LED lamp to the end of the driver.

Preferably, the light guiding unit comprises a plurality of light guiding strips fixed to the rod member at an interval around the axis of the rod member, each light guiding strip has a light incident end portion corresponding to the LED light and a sound adjacent to the light rod The light-emitting end of the end.

Preferably, the screwdriver further includes a plurality of grooves respectively spaced around the axis of the rod and extending along the axis of the rod. The grooves are respectively embedded in the light guide strips.

Preferably, the light guiding strips are fixed in the corresponding grooves by adhesive adhesion.

Preferably, the power supply unit of the LED lighting unit is a USB Rechargeable Battery.

The utility model has the advantages that the light output of the LED lamp disposed in the grip is guided to the end of the screwdriver by the light guiding unit disposed on the rod, and the clear lighting effect is achieved except when the screw is assembled in the dark place. In addition, for the in-line screw, the illumination light is not obscured by the through hole, and the screw can be directly and clearly illuminated to facilitate the assembly.

Other features and effects of the present invention will be apparent from the detailed description of the preferred embodiments of the drawings, wherein: FIG. 1 is a conventional LED-illuminated screwdriver for assembling an in-line screw; 2 is a side view of a preferred embodiment of the LED light guide type screwdriver; FIG. 3 is a side view of the preferred embodiment, illustrating a plurality of grooves in which a plurality of light guide strips are embedded in a rod; Figure 4 is a side cross-sectional view taken on line IV-IV of Figure 3; and Figure 5 is a schematic view showing the preferred embodiment for unloading an in-line screw.

Referring to FIG. 2, a preferred embodiment of the novel light guiding type LED screwdriver includes a screwdriver 1, an LED lighting unit 2, and a light guiding unit 3.

The screwdriver 1 includes a grip 11, a lever member 12 extending outward from an end face of the grip 11 along the axis of the grip 11. The grip 11 has an accommodating space 111, an opening 112 disposed away from an end surface of the rod member 12 and communicating with the accommodating space 111, and an end cover 113 closably sealed to the opening 112. The rod 12 is made of a metal material and has a driver end 121 away from the grip 11.

The LED lighting unit 2 is disposed in the accommodating space 111 of the grip 11, and includes an LED lamp 21 disposed adjacent to the rod member 12, a power supply unit 22 electrically connected to the LED lamp 21, and a power supply unit 22 disposed on the LED lamp 21 The switch 23 of the grip 11. The power supply unit 22 cooperates with the conduction of the switch 23 to form a pair of circuits for supplying power to the LED lamp 21. The power supply unit 22 is a USB (Universal Serial Bus) rechargeable battery, and the USB slot 221 of the power supply unit 22 is opposite to the opening 112. Preferably, the number of LED lamps 21 of the LED lighting unit 2 can be increased according to design or actual needs, and is not limited to one LED lamp 21.

The light guiding unit 3 is disposed on the rod member 12, and includes four light guiding strips 31 fixed to the rod member 12 around the axis of the rod member 12, respectively. Each of the light guiding strips 31 is an acryl light guiding strip, and has a light incident end portion 311 corresponding to the LED lamp 21 and a light exiting end portion 312 adjacent to the starter end portion 121. Each of the light guiding strips 31 is used to guide the light emitted from the LED lamp 21 to the driver end portion 121 for illumination.
