Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a can opener, and particularly to a wheel cutter type can opener.

[0002]

[Prior art]

 As shown in FIG. 1, the conventional can opener is provided with a vertical cutter 101 on one side of the handle body 10 and a hole 10 at the front end of the handle body 10 so that it can be used as a bottle opener. Such a can opener is applied simply by moving the hand back and forth and pushing, and the cutter 101 opens the lid of the can 20. FIG. 2 shows another conventional wheel cutter type can opener, in which two grips 301 and 302 form a pivotal connection, and one side of the two grips 301 and 302 is attached to one side. An active gear and a driven gear 40 are provided, and a wheel cutter 50 is coaxially connected to the outside of the driven gear 40. The active gear and the driven gear 40 can be driven by just meshing with each other. Can be rotated by a hand arranging blade 60 provided on the outside. At the time of use, two handle handles 301 and 302 are sandwiched between the edges of the canned lid, and the handwheel 60 is turned to advance the wheel cutter 50 along the canned lid, and the lid is cut open. In other words, in the above-described conventional wheel cutter type can opener, the incision of the lid is completed by manually turning the blade 60 manually with a finger.

[0003]

[Problems to be solved by the invention]

 However, the force of the finger is limited, and in order to adapt to the operation of the finger, the main body of the hand-operated blade 60 of the conventional wheel cutter type can opener described above is made short and small, and the moment to apply the force is relatively small. Therefore, even if 360 degrees of continuous force is applied, a considerable amount of force is spent, and even if the lid is not completely opened, the finger often gets tired, and it cannot be said that it is perfect. Accordingly, an object of the present invention is to provide a can opener which has a simple structure and can easily cut cans.

[0004]

[Means for Solving the Problems]

 A can opener according to the present invention for solving the above-mentioned problem includes first and second grips and a rocking handle which are pivotally connected, and wheel cutters at upper and lower ends of the pivotally connected ends of the first and second grips, respectively. The gear is pivotally connected, the fixed shaft of the gear is connected to the shank, and the shank is provided with a ratchet coaxial with the gear, and the ratchet meshes with the braking piece and is in contact with the braking piece. Can be driven. The can opener thus constructed is simple in that the gears of the first and second grips and the wheel cutter are sandwiched between the edges of the lid of the can, and then the shank is moved up and down. Can be driven in one direction to easily cut cans.

[0005]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIGS. 3 and 4, a can opener according to an embodiment of the present invention includes two handle handles 1, 2 and a swing handle 3, which are pivotally connected to each other, on the pivotal end of the two handle handles 1, 2. On the lower side, a gear 11 and a wheel cutter 21 are pivotally connected, respectively. The shank 3 is provided with a ratchet 31 connected to the same axis as the gear 11.

The front end of the handle 1 is an appropriate curved portion, the rear end is a long handle portion, and the front end of the curved portion has a hole 12 through which a plug shaft 13 passes, which is connected to the gear 11, and A pivot hole 14 is provided in the middle stage, and a stopper post 15 and rivets 151 and 152 are inserted into the pivot hole 14 to form a movable state with a corresponding end of the handle 2. The front curved portion of the handle 2 is opposed to the curved portion of the handle 1, and the rear end is a long handle, which is movably pivotally connected to the long handle 1, and corresponds to the two handles 1 and 2. The curved portions form a state of being exactly sandwiched. A hole 22 is provided at the front end of the handle 2, and a wheel cutter 21 is attached by a rivet 23. An annular groove 211 is provided inside the wheel cutter 21 so that the two handles 1 and 2 are interposed therebetween. When combined, the gear 11 can be just inserted into the annular groove 211 as shown in FIGS. Further, a locking projection 24 may be provided on the curved portion at the front end of the handle 2, and when the two grips 1 and 2 are sandwiched, the locking projection 24 appropriately fits as shown in FIG. Stop. Further, a hook-shaped groove 25 may be provided at an appropriate position of the handle portion of the grip handle 2 to be used as a bottle opener.

[0007] By the combination of the above members, as shown in FIG. 9, the gear 11 of the two grips 1 and 2 and the wheel cutter 21 can be sandwiched around the periphery of the lid 41 of the can 4, and the swing handle 3 Is moved up and down, and the ratchet 31 provided on the shank 3 is driven in one direction, so that the gear 11 coaxially connected to the ratchet 31 advances along the periphery of the lid 41 of the can 4, In addition, the wheel cutter 21 performs a cutting operation, and cans can be easily opened.

In the above-described coaxial connection of the plug shaft 13, the gear 11 and the ratchet 31, the plug shaft 131 may be rivet-fixed by penetrating the plug shaft 13, the gear 11 and the ratchet 31.

[0009]

[Effect of the invention]

 The can opener of the present invention is provided with two grip handles and a swing handle that are pivotally connected.A wheel cutter and a gear are pivotally connected to the upper and lower sides of the pivot contact end of the two grip handles, respectively. The ratchet is connected with the ratchet, and the ratchet is provided with a ratchet that is driven coaxially with the gear in one direction. The can opener constructed in this way is very elaborate and simple in structure, so it is convenient to use, and two handle grip gears and a wheel cutter are sandwiched around the periphery of a canned lid to form a swing handle. By moving the can up and down, cans can be easily cut open, which is extremely labor-saving and convenient.
