Hereinafter, preferred embodiments of the can opener according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, a can opener according to the present invention includes a body 10 having a first guide groove 12 formed therein and having a curved inner surface, A curved surface which is movable along a first guide groove (! 2) in the body part (10) is formed at one end and a curved surface which is movable along a first guide groove (! 2) And is inserted into a second guide groove 22 formed at the front of the handle 20 so as to be inserted into the handle 20, A hook 30 rotatable about a rotation axis 24 of the hook 20 and having a slope formed on an upper surface of the hook 30 so as to be rotatable about a lifting rotary shaft 26 formed at a front lower end of the pull 20, A rotatable lifting part (40), and a third gauge having a groove formed on the grip part (20) A fourth guide groove 16 formed in the body portion 10 so as to intersect the third guide groove 27 and formed in a straight line and a third guide groove 26 formed in the third guide groove 27, And a guide shaft 18 passing through the groove 16 and movable along the third guide groove 27 and the fourth guide groove 16.

First, a can body 10 according to the present invention is provided. As shown in FIG. 1, the body 10 is formed with a first guide groove 12 which is recessed therein and whose inner side is formed as a curved surface.

The body 10 may be configured such that the body 10 is composed of two plates and the first guide groove 12 in the plate is recessed.

A handle 20 is provided in the first guide groove 12. The handle 20 is configured to be rotatable about a handle rotation axis 14 formed in the body 10. [

A curved surface is formed at one end of the handle 20 so as to be movable along the first guide groove 12 in the body 10 and is protruded at the other end to be held by hand Holes and protrusions are formed.

A second guide groove (22) is provided at the lower end of the handle (20). The second guide groove 22 is formed in the handle 20 so as to provide a space for the hook 30 to be rotated by a predetermined angle. The hooking rotary shaft 24 is provided in the second guide groove 22.

In addition, the second guide groove 22 is provided with a hook 30. The hooking portion 30 is rotatable about the hooking rotary shaft 24 in the second guide groove 22 and has a hooking groove 36 formed at the front thereof.

More specifically, as shown in FIG. 1, the hooking portion 30 includes a first protruding portion 32 positioned above and extending forward and a second protruding portion 32 extending downward relative to the first protruding portion 32 A second protrusion 34 positioned to be relatively small with respect to the first protrusion 32 and a hooking groove 36 formed between the first protrusion 32 and the second protrusion 34 .

The surfaces of the first protrusion 32 and the second protrusion 34 facing each other may be curved. This is for the purpose of allowing the can of the can lid such as canned food to be easily inserted into the hook groove 36.

A hook 38 is provided at a portion where the first projection 32 contacts the hook groove 36 and at a portion where the second projection 34 contacts the hook groove 36. The hooking jaw 38 serves to prevent the hook inserted into the hooking groove 36 from being easily detached.

A lifting portion 40 is provided on a lifting rotary shaft 26 formed at a lower front end of the handle 20. The lifting unit 40 is configured to be rotatable around the lifting rotary shaft 26.

The lifting unit 40 may be configured such that the bottom surface is formed horizontally, the upper surface is formed as an inclined surface, and the tip ends protrude. This serves to guide the hook of the can lid of the canned food to be guided to the hooking groove 36 along the tip and the inclined surface of the lifting part 40.

A third guide groove (27) is formed in the handle (20). As shown in FIG. 1, the third guide groove 27 is formed to penetrate the handle 20 in a curved shape.

A fourth guide groove 16 is formed in the body 10 in a straight line so as to intersect the third guide groove 27. More specifically, as shown in FIG. 2, when the handle 20 rotates, the fourth guide groove 16 is formed in a path along which the third guide groove 27 moves, do.

And a guide shaft 18 passing through the third guide groove 27 and the fourth guide groove 16 is provided. The guide shaft 18 moves along the third guide groove 27 and the fourth guide groove 16 so that the handle 20 rotates about the handle rotation axis 14 with respect to the body 10 And serves to guide the rotation about the center.

As shown in FIG. 1, a plurality of latching grooves 19 are formed on the bottom surface of the body portion 10. As shown in FIG. 2, the catching groove 19 serves to support the edge of the can according to the size of the canned food when using the can opener of the present invention.

A counterbalance 50 is further provided at the rear of the body 10. The counterbalance 50 serves to correspond to the weight of the handle 20. In addition, the counterbalance 50 may rotate about an axis at the rear of the body 10.

Hereinafter, the action of the can opener according to the present invention will be described in detail.

2A, the ring S of the can lid of the can opener is seated on the tip of the lifting part 40 of the can opener of the present invention, and the ring S rises along the inclined surface, 30 are guided to the catching grooves 36. [

2B, when the hook S is hooked on the hooking groove 36, the tip of the lifting part 40 is moved downwardly of the can lid So that one end of the edge of the can lid is opened.

When the handle 20 is further rotated, the can lid is opened as shown in FIG. 2C. At this time, the other edge of the can lid is supported in the engaging groove 19 of the body 10, The can lid can be opened.
