Description

Technical Field

[0001] The present invention relates to the technical field of can openers, and more particularly, to a can opener with an adaptation function. Background Art

[0002] Existing can-opening tools usually have a cutting knife attached to a handle for cutting the joint edge of the can body. However, users have to exert a great deal of force to turn the handle and must hold the can with one hand and operate the cutting knife with the other hand to cut the joint edge of the can body. Such a can-opening method is laborious and inconvenient to operate.

[0003] Publication No. CN106672875A provides a can opener, which includes: an upper seat, a lower seat, a transmission device, an eccentric wheel, a roller, a coupling member, a gasket, a traction wheel and a metal plate. By pressing the first switch, the power of the motor is transmitted through gears to the large gear of the transmission device, causing the eccentric wheel to rotate. Due to the rotation of the eccentric wheel itself, the distance between the spindle of the roller and the axis of the eccentric wheel becomes larger, resulting in the automatic approach of the distance between the spur gear and the traction wheel for can opening. At the same time, the spindle of the spur gear moves outwards, tensioning the torsion spring. At this time, the torsion of the torsion spring is less than the resistance during can opening. When the resistance after can opening is less than the torsion of the torsion spring, due to the reaction force of the torsion spring, the spindle of the spur gear moves inwards, so that the spur gear and the traction wheel separate. When the spindle of the spur gear moves and touches the second switch, the motor stops to complete the automatic can-opening function. This solution mainly performs automatic can-opening operations through the cooperation of the spur gear and the traction wheel. Such a design can achieve convenient and labor-saving can-opening operations, but due to the limitation of the traction wheel, it cannot match cans of different sizes. Therefore, a one-piece cutter wheel and a can opener are provided to solve the problem that the existing can openers cannot match different cans. Summary of the Invention
