An elastic coupling assembly comprises a first brake gear, a second brake gear, a coupling, a plurality of elastic bodies, a plurality of first protrusions, at least two second protrusions; wherein, the plurality of first protrusions is arranged on a surface of the first brake gear which faces the second brake gear; the at least two second protrusions are arranged at intervals on the surface of the coupling which faces the first brake gear; each second protrusion has a notch, each first protrusion is clamped between two adjacent second protrusions; when the first brake gear rotates in one direction, each first protrusion comes into contact with the corresponding elastic body, when the first brake gear rotates in the other direction, each first protrusion comes into contact with the second protrusion opposite to the corresponding elastic body. The present invention further comprises an elastic can opener having the elastic coupling assembly.

The present invention discloses an electric vacuum-pumping and tinfoil-cutting integrated machine. The integrated machine has a housing which comprises a fixed outer housing having an outer housing receiving cavity formed therein and a fixed inner housing having an inner housing receiving cavity formed therein, wherein a PCB and a battery are embedded in the inner housing receiving cavity of the fixed inner housing; and an electric tinfoil-cutting assembly is embedded on an upper end side of the fixed inner housing inside the outer housing receiving cavity of the fixed outer housing, and an electric vacuum-pumping assembly is embedded on a lower end side of the fixed inner housing inside the outer housing receiving cavity of the fixed outer housing. The present invention can achieve a vacuum-pumping function and a tinfoil-cutting function, and has the advantages of novel structural design, diversified functions and convenience in use.

An electric can opener with rotating spherical joint for removal a lid from a can is provided. The rotation of motorized driver in a helical cam moves readily a cutting blade toward a transport wheel to engage the end of the can, so that it is in the proper condition to cut end from the can. Further rotation of the transport wheel, forces the can against the blade to cut the end of the can.

An automated can opener includes a pry lip mounted to the lower surface of the housing and extending toward a drive gear. The pry lip configured to be inserted into a seam cut into the rim of the can.

A can opener contains: a first holder, a second holder, a transmission device, an eccentric gear, a rotating roller, a connector, a washer, a guiding roller, and a metal piece. The first holder includes a battery chamber, a cover, and a first switch. The second holder includes a first accommodation room, a plurality of first posts, and a second accommodation room. The transmission device includes a motor, a plurality of first driving gears, and a second driving gear. The eccentric gear includes an opening and a plurality of coupling pillars. The rotating roller includes a second post, and the connector includes a second arcuate orifice, a plurality of second coupling stems, and two second positioning pillars. The washer includes a third arcuate orifice and a fixing hole. The guiding roller includes a first pore and an abutting portion, and the metal piece includes a second pore and a contacting gear.

A power assist unit (70) to rotate the twist knob (50) of a typical manual can opener (20) includes a coupling head (72) that is rotated or powered by a hand-held power unit (74). The coupling head includes an elongated crossbar (76) connected at its center to a torque shaft (78) that projects outwardly from the head portion (80) of the power unit. Parallel engagement pins (82) project from the crossbar (76) to bear against opposite sides of the twist knob (50) for rotation of the twist knob.

Disclosed is a portable electric can opener, including an opener body. A bottom wall of the opener body is bent to form an L-shaped mounting portion; the cutting wheel penetrates out of a vertical side wall of the L-shaped mounting portion; the driving wheel is penetrates out of a horizontal wall surface of the L-shaped mounting portion; with a structural center of gravity distribution of the driving wheel device, the can opener can be directly placed on a can body; after the can opener is started, the driving wheel moves towards the cutting wheel to clamp the rim of the can body and walks along a top of the rim of the can body, so that the cutting wheel cuts the rim of the can body to finally automatically complete lid opening, so as to free both hands.
