The rear end cap 130 includes a power switch 134 at the center thereof for contacting the negative electrode of the battery 160.

Each of the folding knives 140 and 150 includes first and second flat plates 141 and 151, second flat plates 142 and 152, decorative covers 143 and 153, locking levers 144 and 154, spacers 145 and 155, Blades 146 and 156, and a fixed shaft 147.

The first and second flat plates 141 and 151, the second flat plates 142 and 152, the decorative covers 143 and 153, the locking levers 144 and 154 and the spacers 145 and 155 are assembled to form a sheath. The first flat plates 141 and 151 are metal plates and the lower bent portions 141a and 151a and the upper bent portions 141b and 151b are integrally formed at the lower and upper edges, respectively. The lower bent portions 141a and 151a are inserted into the sliding engagement grooves 111a and 112a and the upper bent portions 141b and 151b are inserted into the sliding engagement grooves 111b and 112b. The width between the lower bent portions 141a and 151a and the upper bent portions 141b and 151b of the first flat plates 141 and 151 is equal to or greater than the width between the sliding engagement grooves 111a and 111b and 112a and 112b It is preferable to have a large size. It is preferable that the first flat plates 141 and 151 are elastically inserted and coupled when the first flat plates 141 and 151 are coupled between the sliding engagement grooves 111a and 111b . Since the coupling is thermally tightly coupled to the flashlight body 110 through the incision surface of the body 110 while firmly coupling the knives 140 and 150, heat generated from the LED module is transmitted through the body 110, As well as a radiating function for radiating heat to the outside.

The decorative covers (143, 153) are coupled to the outer surfaces of the second flat plates (142, 152). The decorative covers 143 and 153 can provide an external design effect of the flashlight and the knife.

The first and second flat plates 141 and 151 and the second flat plates 142 and 152 are coupled in a sheath shape via locking levers 144 and 154 and spacers 145 and 155. The locking lever 144 includes a locking projection 144a and a hinge hole 144b protrusion 144c. The locking lever 144 is seated between the upper edges of the first flat plates 141 and 151 with the hinge hole 144b as a rotational center. The locking protrusions 144a and the protrusions 144c of the locking lever 144 are disposed opposite to each other with respect to the hinge hole 144b. The spacers 145 and 155 are fixed in a rivet manner between the first flat plates 141 and 151 and the rear edges of the second flat plates 142 and 152. The upper ends of the spacers 145 and 155 are arranged to support the rear ends of the locking levers 144 and 154. Therefore, when the protrusions 144c and 154c of the locking levers 144 and 154 are pressed, the spacers 145 and 155 support the rear ends of the locking levers 144 and 154. When the pressing force is removed, Is restored to its original position by elastic biasing force.

The knife blades 146 and 156 are formed with hinge holes 146a and 156a at the rear end center and locking grooves 146b and 156b at the rear end of the knife blade. Therefore, the knife blades 146 and 156 are rotatably coupled to the fixed shaft 147 and the hinge holes 146a and 156a are rotatable about the fixed shaft, and are rotatable between the front ends of the first and second flat plates 141 and 151 Lt; / RTI >

FIG. 6 is a view for explaining the back surface of FIG. 1, the blade open state and the folded state. 6, when the knife 146 is unfolded, the locking protrusion 144a of the locking lever 144 is inserted into the locking groove 146b, and the knife 146 is locked at 180 degrees. The locking lever 144 not only holds the blade 180 degrees in rotation, but also prevents the blade from being folded again. Therefore, in order to fold the blade 146, if the protrusion 144b of the locking lever 144 is pressed, the locking projection 144a is disengaged from the locking groove 146b, so that the locking of the blade 146 is released. In the folded state of the knife blade 146, the rear end of the knife blade is held in a state where the locking protrusion 144a of the locking lever 144 pushes the knife blade about the hinge hole 146a. Therefore, the blade 146 is kept folded in the sheath until an external force is applied.

The knives 140 and 150 are assembled and mounted on the sliding engagement grooves 111a and 111b (112a and 112b). The rear end of the knives 140 and 150 mounted on the incision surface of the body 110 is supported by the front end of the rear end cap 130,

Therefore, even if a knife is attached to the body 110, the entire outer shape maintains the appearance of the flashlight, so that the function as a flashlight can be sufficiently exhibited at normal times. In the case of using a knife at night, it is very convenient to use because it can illuminate sufficiently strong lighting from the side of the blade, so it can work in a very bright environment without knife shadow. In addition, in order to illuminate a strong light, the LED element generates a lot of heat, but the knife portion is thermally tightly coupled to the body to serve as a heat emission passage, thereby covering the thermal problem of the LED illumination.

Fig. 7 shows a perspective view of another preferred embodiment of the present invention in which the blade of the folding knife-equipped flashlight is unfolded.

The foldable knife-equipped flashlight 200 of another embodiment includes a body 210, a lamp head portion 220, a rear end cap 230, and an outer knife 240. The foldable knife-equipped flashlight 200 is coupled so that the blade is located at the rear of the light output port when the user's eye is centered so as to prevent the blade shadow from being generated due to the outer blade structure.

In the above-described embodiment, the main knife 140 is left as it is and the remaining knife 150 can be replaced with another hand tool such as a driver, an auger, or a wrench.

This design combines the folding knife to the outer periphery of the flashlight, and it can illuminate the blade part from the side with powerful illumination, so it can be used very much in outdoor activities such as fishing, hunting and camping while demonstrating the function of the flashlight at night.

Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the following claims It will be understood that the invention may be modified and varied without departing from the scope of the invention.
