Improved structure of can opener

The present invention relates to an improved construction of a can opener, which refers to a can opener construction that can be opened by rotation and applied to left and right tweezers.

In general life, canned foods have a long shelf life and are convenient to carry and eat. They are foods that are often used for outdoor tourism or picnics, and can openers are necessary tools for opening metal cans. The common can opener is used because the position of the cutting edge is on the left side of the pressing handle body. This is designed for the right scorpion, so the left scorpion is difficult to use, and the conventional can opener cannot be selected by the user. The can lid is opened, and when the can is cut out, the user must open the cut cover by hand, and the contents of the can often have soup, which is easy for the user to open the cover. Contamination to the contents is even easy to be cut by the cover, so it is necessary to improve.

Refer to the Republic of China Patent Announcement No. 365993 "Second Case of Wheel Knife Opener", which mainly solves the following problems: the conventional wheel cutter type can opener, which uses the continuous rotation of the finger to complete the cutting work, but the finger The output is limited, and it is suitable for the twisting operation of the finger. Therefore, the body of the knob is usually short and the force applied is relatively small, so that it is still difficult and laborious when continuously applying force, often before it is fully opened. Has caused finger acid fatigue.

In order to solve the above problems, the main structure of the patent is composed of two pivoting handles and a crank handle, and a wheel cutter and a tooth are mainly arranged on the upper and lower sides of the pivotal ends of the two grips. The wheel and the fixed shaft of the gear form an extension joint with the crank handle, and the rocker handle is provided with a coaxial ratchet wheel, and the ratchet wheel is in meshing contact with a brake pad, so that the ratchet wheel is constantly driven in one direction.

Although the above patent discloses that the two-handle gear and the wheel cutter can be clamped to the side wall of the can of the can, and then the rocker is rocked up and down, so that the gear of the handle can be driven in one direction and the can is easily and conveniently completed. The work is turned on, but the single wheel cutter takes a long time to cut along the top edge of the can, and when the cutting is completed, the top cover cannot be picked up at the same time.

Since the prior art is still unable to perfect such problems, it is necessary to break through and solve them. Therefore, how to improve convenience, practicability and economic benefits is a key project that the industry should strive to solve and overcome.

Therefore, the creators of this case have developed a solution that is more convenient, practical and economical in view of the fact that the lack of conventional can opener is ideal. Construction, in order to promote the development of society, and the creation of this creation.

Based on the improvement that the conventional can opener does not have the possibility of opening and closing the can lid, the creator is committed to researching and creating an improved structure of the can opener, the structure of which is as follows: an improved structure of the can opener, including: a telescopic cutting device comprising two corresponding cutting units, the cutting unit comprising a blade, and a telescopic unit connected between the two cutting units for adjusting the distance between the two cutting units, the telescopic unit The utility model comprises a cylinder and a piston rod which is movable and movable in the cylinder body, and a fastener is arranged on the outer side wall of the cutting unit, and the piston rod is connected thereto One of the cutting units, the barrel is connected to the other of the cutting units; and a holding unit, the holding unit is disposed on the telescopic cutting device and connected to one side of the telescopic unit.

In this embodiment, the holding unit includes a rod body, one end of the rod body is connected to the telescopic unit, and the other end of the rod body is provided with a handle.

In this embodiment, an elastic unit is disposed between the two cutting units, and the elastic unit is a telescopic spring.

The advantages of the benefits achieved by this creation are as follows:

1. This creation can be applied to the left and right hand tweezers, and then the can lid is cut by one-hand rotary cutting, which is more labor-saving.

2. This creation can be adjusted according to the size of various cans, and at the same time, the cut cover can be removed.

In order to give the reviewers a better understanding and understanding of the features of the creation and the efficacies achieved, the following is a description of the preferred embodiment and the detailed description. Three-dimensional structure diagram and second picture creation In a partial cross-sectional view, the present invention is an improved structure of a can opener, comprising: a telescopic cutting device 1 comprising two corresponding cutting units 10, the cutting unit 10 comprising a blade 100, the two A telescopic unit 12 is connected between the cutting units 10 for adjusting the distance between the two cutting units 10 . The telescopic unit 12 includes a cylinder 122 and a piston rod 120 telescopically movable in the cylinder 122 . The telescopic cutting device 1 further includes a fastening member 14 disposed on an outer side wall of the cutting unit 10. The piston rod 120 is connected to one of the cutting units 10, and the cylindrical body 122 is connected to the other cutting unit 10 by the piston rod. 120 is moved in the cylinder 122 to adjust the distance between the two cutting units 10; and a holding unit 3 is disposed on the telescopic cutting device 1 and connected to one of the telescopic units On the side, the holding unit 3 includes a rod 30. One end of the rod 30 is connected to the telescopic unit, and the other end of the rod 30 is provided with a handle 32.

Referring to the third embodiment, the first embodiment of the present invention uses a schematic diagram. If a can of a larger diameter is encountered, the two cutting units 10 are held open by the hand, and the piston rod 120 is stretched between the cylinders 122. Adjusting the action so that the cutting unit 10 can be smoothly opened, and then the cutting unit 10 is placed on the can, and the edge of the can lid A is more than the convex portion between the fastener 14 and the cutting unit 10, the blade 100 is pressed against the can lid A, and the handle 32 is pulled downward.
