Description

Technical Field

[0001] The utility model relates to the technical field of can-opening tools, and particularly relates to a knobless can opener. Background Art

[0002] For the convenience of life, people process some cooked products and pack them into cans for sealing. When needed, just open the can lid to eat, which is very fast. Since there are many varieties of canned foods, most of them are packaged in tinplate cans. When eating such canned foods, a cutting tool is needed to cut open the lid to take out the food. Therefore, can openers have emerged on the market, and the commonly used can openers are manual can openers and electric can openers.

[0003] However, in the existing manual can opener, generally, there is a handle, a rotating group and a cutting group, and the rotating group is connected with a knob. By manually turning the knob, the rotating group is rotated, and the cutting group cooperates with the rotating rotating group to cut the can lid. However, such a can opener needs to be provided with a knob to drive the rotating group to rotate, resulting in inconvenient operation when using the can opener. Moreover, since a knob needs to be added, the overall shape of the can opener is not beautiful enough. Therefore, the existing manual can opener needs to be improved. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a knobless can opener with reasonable design, simple and convenient operation, and beautiful and generous appearance.

[0005] To solve the above technical problems, the utility model can adopt the following technical solutions:

[0006] A knobless can opener includes a base, a power mechanism, a cutting rotation driving mechanism, a cutting mechanism and a handle. The power mechanism, the cutting rotation driving mechanism and the cutting mechanism are respectively installed on the base, and the power mechanism is connected with the cutting rotation driving mechanism. A meshing state is formed between the cutting rotation driving mechanism and the cutting mechanism. The handle includes an upper swing handle and a lower swing handle. The upper swing handle and the lower swing handle are respectively rotatably arranged on the upper and lower sides of the base and are respectively connected with the power mechanism. When the upper swing handle and the lower swing handle are opened / closed, both will drive the power mechanism to operate, and the power mechanism will drive the cutting rotation driving mechanism to rotate in the same direction.

[0007] In one embodiment, the power mechanism includes a power gear, a ratchet unit I, a ratchet unit II, a transmission gear and a ratchet spring. The power gear is respectively connected with the handle and the ratchet unit I. The ratchet unit I and the ratchet unit II are respectively connected with the cutting rotation driving mechanism. The transmission gear is respectively connected to the ratchet unit I and the ratchet unit II. The two ends of the ratchet spring respectively abut against the ratchet unit I and the ratchet unit II.

[0008] In one embodiment, the ratchet unit I includes a driving fixed ratchet I and a driven sliding ratchet I. The driving fixed ratchet I is fixedly connected to the power gear, and one-way teeth I are respectively provided on the driving fixed ratchet I and the driven sliding ratchet I. The one-way teeth I of the driving fixed ratchet I mesh with the one-way teeth I of the driven sliding ratchet I. A conical tooth I meshing with the transmission gear is also provided on the driving fixed ratchet I.

[0009] In one embodiment, the ratchet unit II includes a driving fixed ratchet II and a driven sliding ratchet II. One-way teeth II are respectively provided on the driving fixed ratchet II and the driven sliding ratchet II. The one-way teeth II of the driving fixed ratchet II mesh with the one-way teeth II of the driven sliding ratchet II. A conical tooth II meshing with the transmission gear is also provided on the driving fixed ratchet II.

[0010] In one embodiment, the meshing direction of the driving fixed ratchet I and the driven sliding ratchet I is opposite to the meshing direction of the driving fixed ratchet II and the driven sliding ratchet II.

[0011] In one embodiment, the cutting rotary drive mechanism includes a cone bit rod, a transmission shaft, an inclined wedge sleeve, an inclined wedge friction plate and a through pin.

One end of the transmission shaft is connected to the inclined wedge sleeve, and the other end is respectively connected to the ratchet unit I and the ratchet unit II. The transmission shaft and the cone bit rod are on the same axis. A limiting hole is opened on the cone bit rod, and the through pin is inserted into the limiting hole to limit the inclined wedge friction plate and the inclined wedge sleeve. A shaft sleeve is also sleeved on the cone bit rod, and a return compression spring is provided between the shaft sleeve and the cone bit disk.

[0012] In one embodiment, a connecting head is provided at one end of the transmission shaft.

When an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. On the contrary, when an element is referred to as being "directly on" another element, there is no intermediate element.

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this utility model belongs. The terms used in the description of this utility model herein are for the purpose of describing specific embodiments only and are not intended to limit this utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0036] Please refer to Figures 1 to 9 , a knobless can opener, comprising a base 100, a power mechanism 200, a cutting rotation driving mechanism 300, a cutting mechanism 400 and a handle 500. The power mechanism 200, the cutting rotation driving mechanism 300 and the cutting mechanism 400 are respectively installed on the base 100, and the power mechanism 200 is connected to the cutting rotation driving mechanism 300. A biting state is formed between the cutting rotation driving mechanism 300 and the cutting mechanism 400. The handle 500 includes an upper swing handle 510 and a lower swing handle 520. The upper swing handle 510 and the lower swing handle 520 are respectively rotatably arranged on the upper and lower sides of the base 100 and are respectively connected to the power mechanism 200. When the upper swing handle 510 and the lower swing handle 520 are opened / closed, they will both drive the power mechanism 200 to operate, and the power mechanism 200 will drive the cutting rotation driving mechanism 300 to rotate in the same direction.

[0037] Specifically, in this embodiment, the upper swing handle 510 and the lower swing handle 520 of the handle 500 are respectively arranged on the upper and lower sides of the base 100, while the power mechanism 200, the cutting rotation driving mechanism 300 and the cutting mechanism 400 are respectively arranged on the base 100. Among them, the upper swing handle 510 and the lower swing handle 520 are respectively connected to the power mechanism 200, and the power mechanism 200 is also connected to the cutting rotation driving mechanism 300. When cutting a can lid is required, the user places the can lid between the cutting rotation driving mechanism 300 and the cutting mechanism 400, and the cutting rotation driving mechanism 300 and the cutting mechanism 400 bite the can lid. Then the user opens the upper swing handle 510 and the lower swing handle 520. While the upper swing handle 510 and the lower swing handle 520 are being opened, they will drive the power mechanism 200 to rotate. While the power mechanism 200 is rotating, it will drive the cutting rotation driving mechanism 300 to rotate clockwise. Similarly, when the user closes the upper swing handle 510 and the lower swing handle 520, the upper swing handle 510 and the lower swing handle 520 will also drive the power mechanism 200 to rotate. While the power mechanism 200 is rotating, it will also drive the cutting rotation driving mechanism 300 to rotate clockwise. When the cutting rotation driving mechanism 300 rotates clockwise, it will cooperate with the cutting mechanism 400 to realize the cutting of the can lid. Finally, by opening or closing the upper swing handle 510 and the lower swing handle 520, the power mechanism 200 is driven to operate. When the power mechanism 200 is operating, it will make the cutting rotation driving mechanism 300 always rotate in one direction, so that the structural design of the can opener is reasonable, the operation is more convenient and simple, and the knob in the prior art can be simplified, making the overall appearance of the can opener more beautiful and generous.

[0038] Please refer to Figures 2 to 4 , in order to enable the upper swing handle 510 and the lower swing handle 520 to drive the power mechanism 200 to rotate when opening / closing, therefore, in this embodiment, racks 530 are provided on both the upper swing handle 510 and the lower swing handle 520 of the handle 500. Among them, the racks 530 can be integrally formed with the upper swing handle 510 and the lower swing handle 520, or can be separately arranged, and are specifically selected according to actual needs. By means of the racks 530, the power mechanism 200 can be driven to operate, and further the cutting rotation driving mechanism 300 can be rotated to realize the cutting function of the can lid.

[0039] The power mechanism 200 includes a power gear 210, a ratchet unit I 220, a ratchet unit II 230, a transmission gear 240, and a ratchet spring 250. Among them, the power gear 210 meshes with the racks 530 of the upper swing handle 510 and the lower swing handle 520, and is connected to the ratchet unit I 220. The cutting rotation drive mechanism 300 is respectively connected to the ratchet unit I 220 and the ratchet unit II 230. The two ends of the ratchet spring 250 respectively abut against the ratchet unit I 220 and the ratchet unit II 230. When the upper swing handle 510 and the lower swing handle 520 are opened, the power gear 210 will be driven to rotate by the racks 530. The power gear 210 will drive the ratchet unit I 220 to rotate. While the ratchet unit I 220 is rotating, it drives the cutting rotation drive mechanism 300 to rotate clockwise. When the upper swing handle 510 and the lower swing handle 520 are closed, the power gear 210 will also be driven to rotate by the racks 530. The power gear 210 drives the ratchet unit I 220 to rotate. The ratchet unit I 220 drives the ratchet unit II 230 to rotate through the transmission gear 240. While the ratchet unit II 230 is rotating, it drives the cutting rotation drive mechanism 300 to rotate clockwise, so that the cutting rotation drive mechanism 300 always rotates in one direction to realize the cutting of the can lid.

[0040] Please refer to Figures 2 to 6 , in order to enable the ratchet unit I 220 and the ratchet unit II 230 to reasonably drive the cutting rotation drive mechanism 300 to rotate. Therefore, in this embodiment, the ratchet unit I 220 includes a driving fixed ratchet I 221 and a driven sliding ratchet I 222. The driving fixed ratchet I 221 is fixedly connected to the power gear 210 by screws. One-way teeth I 223 are respectively arranged on the driving fixed ratchet I 221 and the driven sliding ratchet I 222. The one-way teeth I 223 of the driving fixed ratchet I 221 mesh with the one-way teeth I 223 of the driven sliding ratchet I 222. A bevel gear I 224 meshing with the transmission gear 240 is also arranged on the driving fixed ratchet I 221. The ratchet unit II 230 includes a driving fixed ratchet II 231 and a driven sliding ratchet II 232. One-way teeth II 233 are respectively arranged on the driving fixed ratchet II 231 and the driven sliding ratchet II 232. The one-way teeth II 233 of the driving fixed ratchet II 231 mesh with the one-way teeth II 233 of the driven sliding ratchet II 232. A bevel gear II 234 meshing with the transmission gear 240 is also arranged on the driving fixed ratchet II 231.

[0041] When the upper swing handle 510 and the lower swing handle 520 are opened, the power gear 210 will drive the active fixed ratchet wheel I 221 to rotate. When the active fixed ratchet wheel I 221 rotates, through the engagement between the one-way teeth I 223, it will drive the driven sliding ratchet wheel I 222 to rotate, and then drive the cutting rotation drive mechanism 300 to rotate through the driven sliding ratchet wheel I 222; when the active fixed ratchet wheel I 221 drives the driven sliding ratchet wheel I 222 to rotate, without external force applied, the active fixed ratchet wheel II 231 and the driven sliding ratchet wheel II 232 will bounce between each other. Therefore, when the upper swing handle 510 and the lower swing handle 520 are opened, only the ratchet unit I 220 will drive the cutting rotation drive mechanism 300 to rotate.

[0042] When the upper swing handle 510 and the lower swing handle 520 are closed, the power gear 210 will drive the active fixed ratchet wheel I 221 to rotate in the reverse direction. When the active fixed ratchet wheel I 221 rotates in the reverse direction, without external force applied, there will be a bounce between the active fixed ratchet wheel I 221 and the driven sliding ratchet wheel I 222, and it cannot drive the driven sliding ratchet wheel I 222 to rotate. Therefore, the ratchet unit I 220 will not act on the cutting rotation drive mechanism 300; at this time, through the transmission gear 240 meshing with the conical tooth I 224 of the active fixed ratchet wheel I 221 and the conical tooth II 234 of the active fixed ratchet wheel II 231 respectively, the active fixed ratchet wheel I 221 will drive the active fixed ratchet wheel II 231 to rotate. The active fixed ratchet wheel II 231 will drive the driven sliding ratchet wheel II 232 to rotate through the engagement of the one-way tooth II 233, and then drive the cutting rotation drive mechanism 300 to rotate through the driven sliding ratchet wheel II 232. Finally, the ratchet unit I 220 and the ratchet unit II 230 can drive the cutting rotation drive mechanism 300 to rotate reasonably, and make the cutting rotation drive mechanism 300 always rotate in one direction.

[0043] In order to make the ratchet unit I 220 and the ratchet unit II 230 drive the cutting rotation drive mechanism 300 to rotate alternately, the meshing direction between the active fixed ratchet wheel I 221 and the driven sliding ratchet wheel I 222 is opposite to the meshing direction between the active fixed ratchet wheel II 231 and the driven sliding ratchet wheel II 232.

[0044] Specifically during operation, place the can lid between the cutting rotation drive mechanism 300 and the cutting mechanism 400. The cutting rotation drive mechanism 300 and the cutting mechanism 400 bite on the can lid. At this time, the user opens the upper swing handle 510 and the lower swing handle 520 of the handle 500. While the upper swing handle 510 and the lower swing handle 520 are being opened, they will drive the power gear 210 to rotate. When the power gear 210 is rotating, the active fixed ratchet wheel I 221 connected to it will rotate. Since the driven sliding ratchet wheel I 222 is connected to the active fixed ratchet wheel I 221 through the one-way tooth I 223, the driven sliding ratchet wheel I 222 will also rotate. At this time, the driven sliding ratchet wheel I 222 will drive the cutting rotation drive mechanism 300 to rotate clockwise.

[0045] When the active fixed ratchet wheel I 221 is rotating, it will drive the active fixed ratchet wheel II 231 to rotate as well due to the transmission gear 240. However, since the meshing direction of the one-way tooth II 233 between the active fixed ratchet wheel II 231 and the driven sliding ratchet wheel II 232 is opposite to the meshing direction of the one-way tooth I 223 between the active fixed ratchet wheel I 221 and the driven sliding ratchet wheel I 222, when the active fixed ratchet wheel II 231 rotates, it will not drive the driven sliding ratchet wheel II 232 to rotate. At this time, when the power mechanism 200 is operating, only the ratchet unit I 220 acts on the cutting rotation drive mechanism 300, and the driven sliding ratchet wheel II 232 in the ratchet unit II 230 will bounce with the active fixed ratchet wheel II 231 through the ratchet spring 250, and the driven sliding ratchet wheel II 232 will not act on the cutting rotation drive mechanism 300.

[0046] When the upper swing handle 510 and the lower swing handle 520 are being closed, the upper swing handle 510 and the lower swing handle 520 will also drive the power gear 210 to rotate. When the power gear 210 is rotating, the active fixed ratchet wheel I 221 connected to it will also rotate. At this time, due to the setting of the one-way tooth I 223 (the meshing direction of the active fixed ratchet wheel I 221 and the driven sliding ratchet wheel I 222 is opposite to the meshing direction of the active fixed ratchet wheel II 231 and the driven sliding ratchet wheel II 232), the active fixed ratchet wheel I 221 cannot drive the driven sliding ratchet wheel I 222 to rotate, and there will be a bounce between the driven sliding ratchet wheel I 222 and the active fixed ratchet wheel I 221. Therefore, the ratchet unit I 220 cannot act on the cutting rotation drive mechanism 300.

[0047] Under the action of the transmission gear 230, the driving fixed ratchet wheel I 221 will drive the driving fixed ratchet wheel II 231 to rotate. When the driving fixed ratchet wheel II 231 is rotating, due to the setting of the one-way teeth II 233 (the meshing directions of the driving fixed ratchet wheel I 221 and the driven sliding ratchet wheel I 222 are opposite to those of the driving fixed ratchet wheel II 231 and the driven sliding ratchet wheel II 232), therefore, it can drive the driven sliding ratchet wheel II 232 to rotate. When the driven sliding ratchet wheel II 232 is rotating, it will drive the cutting rotation driving mechanism 300 to rotate clockwise, so that the ratchet unit II 230 acts on the cutting rotation driving mechanism 300.

[0048] Finally, due to the meshing directions of the driving fixed ratchet wheel I 221 and the driven sliding ratchet wheel I 222 being opposite to those of the driving fixed ratchet wheel II 231 and the driven sliding ratchet wheel II 232, when the upper swing handle 510 and the lower swing handle 520 of the handle 500 are opened or closed, they will drive the cutting rotation driving mechanism 300 to rotate in the same direction (clockwise) through the ratchet unit I 220 or the ratchet unit II 230, so that the structural design of the can opener is reasonable and the operation is more convenient and simple. At the same time, by opening / closing the handle 500, the cutting rotation driving mechanism 300 can be driven to rotate. Therefore, the knob in the prior art can be simplified, the cutting efficiency can be doubled, and the overall appearance of the can opener is more beautiful and generous.

[0049] In addition, transmission gears 240 are arranged on both sides of the ratchet unit I 220 and the ratchet unit II 230. By arranging the transmission gears 240 on both sides respectively, the transmission can be more stable, thus ensuring the transmission effect between the transmission gears 240 and the ratchet unit I 220 and the ratchet unit II 230.

[0050] Please refer to Figure 3 、 Figure 7 and Figure 9 As shown in, the cutting rotation driving mechanism 300 in this embodiment includes a cone rod 310, a transmission shaft 320, an inclined wedge sleeve 330, an inclined wedge friction plate 340 and a through pin 350. Among them, one end of the cone rod 310 has a cone disk 311, and the other end penetrates into the base 100. The inclined wedge sleeve 330 and the inclined wedge friction plate 340 are respectively sleeved on the cone rod 310, and the inclined wedge friction plate 340 is stacked on the inclined wedge sleeve 330. A connecting head 321 is arranged at one end of the transmission shaft 320. The connecting head 321 is sleeved with the inclined wedge sleeve 330. After the transmission shaft 320 is sleeved with the inclined wedge sleeve 330 on the cone rod 310, the transmission shaft 320 and the cone rod 310 are on the same axis. By the rotation of the transmission shaft 320, the cone rod 310 is driven to rotate. The other end of the transmission shaft 320 penetrates into the ratchet unit I 220 and the ratchet unit II 230 and is respectively connected with the driven sliding ratchet wheel I 222 and the driven sliding ratchet wheel II 232.

[0051] To ensure that the driven sliding ratchet wheel I 222 and the driven sliding ratchet wheel II 232 can drive the transmission shaft 320 to rotate, therefore, the transmission shaft 320 can adopt a square structure, and the driven sliding ratchet wheel I 222 and the driven sliding ratchet wheel II 232 are both provided with square holes that cooperate with the square-structured transmission shaft 320. Through the square holes, it can be ensured that the driven sliding ratchet wheel I 222 and the driven sliding ratchet wheel II 232 can drive the transmission shaft 320 to rotate, thereby enabling the transmission shaft 320 to drive the cone rod 310 to rotate. Of course, the transmission shaft 320 can also adopt other shaped structures to connect with the driven sliding ratchet wheel I 222 and the driven sliding ratchet wheel II 232, which is not limited here.

[0052] Furthermore, in order to limit the wedge sleeve 330 and the wedge friction plate 340 on the cone rod 310, a limiting hole 312 is also provided on the cone rod 310. The through pin 350 is inserted into the limiting hole 312 to realize the limitation of the wedge friction plate 340 and the wedge sleeve 330. After the can lid is placed between the cutting rotary drive mechanism 300 and the cutting mechanism 400, the cone disk 311 at the end of the cone rod 310 will cooperate with the cutting mechanism 400 to bite the can lid. When the upper swing handle 510 and the lower swing handle 520 of the handle 500 are opened, the ratchet unit I 220 in the power mechanism 200 will drive the transmission shaft 320 to rotate, thereby driving the cone rod 310 to rotate. When the cone rod 310 rotates, it will drive the through pin 350 to rotate. The through pin 350 will run relatively to the wedge friction plate 340, and through the wedge friction plate 340, the cone rod 340 will perform axial movement, thereby reducing the biting distance between the cone disk 311 and the cutting mechanism 400 and realizing the axial locking of the cutting rotary drive mechanism 300, so as to facilitate the cutting of the can lid.

[0053] In addition, a bushing 360 is also sleeved on the cone rod 310, and a return compression spring 370 is provided between the bushing 360 and the cone disk 311. When the cone rod 310 is axially locked, the cone disk 311 will squeeze the return compression spring 370. When the cone rod 310 drives the through pin 350 to rotate in the reverse direction, the through pin 350 will run relatively to the wedge friction plate 340 in the reverse direction. Under the elastic force of the return compression spring 370, the cone rod 310 performs axial movement reset, and the biting distance between the cone disk 311 and the cutting mechanism 400 is reset and increased, thereby realizing the axial unlocking of the cutting rotary drive mechanism 300. The axial movement structure of the cutting rotary drive mechanism 300 in this embodiment is prior art and can refer to Chinese Patent: CN221070938U, so it will not be elaborated here.

[0054] In order to enable the cutting mechanism 400 to cooperate with the cutting rotation driving mechanism 300, therefore, in this embodiment, the cutting mechanism 400 includes a fixed locking pin shaft 410, a cutter wheel 420, and a supporting wheel 430. An installation groove 110 is formed in the base 100. The fixed locking pin shaft 410 passes through the installation groove 110. The cutter wheel 420 and the supporting wheel 430 are respectively sleeved on the fixed locking pin shaft 410 and are located in the installation groove 110. By respectively arranging the supporting wheel 430 and the cutter wheel 420 in the installation groove 110, the cutter wheel 420 is made to cooperate with the gear wheel disc 311 at the end of the gear wheel rod 310, so as to realize the biting and cutting of the canned food lid, thereby forming the function of opening the can. And this cutting mechanism 400 is also prior art. For details, reference can be made to Chinese Patent: CN221070938U.

[0055] Finally, please refer to Figure 2 、 Figure 3 、 Figure 8 and Figure 9 When the cutting rotation driving mechanism 300 cooperates with the cutting mechanism 400 to cut the canned food lid, the canned food lid can be directly removed from the can. After removal, in order to facilitate the discarding of the canned food lid, in this embodiment, a reverse reset mechanism 600 is further provided on the base 100. Among them, the reverse reset mechanism 600 includes a pressing member 610 and a spring piece 620. The pressing member 610 can act on the driven sliding ratchet wheel I 222 and the driven sliding ratchet wheel II 232 respectively. The spring piece 620 can elastically reset the pressing member 610, and the pressing member 610 is provided with an inclined pressing surface 611 and a blocking portion 612. When the pressing member 610 is pressed downward under the action of an external force, the inclined pressing surface 611 of the pressing member 610 will act on the driven sliding ratchet wheel I 222, so that the driven sliding ratchet wheel I 222 is disengaged from the active fixed ratchet wheel I 221. At the same time, the blocking portion 612 of the pressing member 610 will limit and press the driven sliding ratchet wheel II 232, so that the driven sliding ratchet wheel II 232 is tightly connected to the active fixed ratchet wheel II 231.

[0056] The spring piece 620 in the reverse reset mechanism 600 will abut against the pressing member 610. When there is no external force acting on the pressing member 610, the spring piece 620 can elastically reset the pressing member 610. After the pressing member 610 is reset, the driven sliding ratchet wheel I 222 and the driven sliding ratchet wheel II 232 can also be reset by the ratchet spring 250.

[0057] In this embodiment, specifically when removing the lid, after the can lid is cut and removed, the user can directly press the pressing member 610, so that the inclined pressing surface 611 of the pressing member 610 acts on the driven sliding ratchet wheel I 222, thereby enabling the axial movement of the driven sliding ratchet wheel I 222 and disengaging from the meshing state with the driving fixed ratchet wheel I 221. When the driven sliding ratchet wheel I 222 moves axially, it will squeeze the ratchet spring 250, so that the ratchet spring 250 acts on the driven sliding ratchet wheel II 232, making the driven sliding ratchet wheel II 232 and the driving fixed ratchet wheel II 231 tightly meshed and connected. At the same time, the stopper portion 612 of the pressing member 610 will also move and limit and press the side wall of the driven sliding ratchet wheel II 232, so that the driven sliding ratchet wheel II 232 can be more tightly meshed and connected with the driving fixed ratchet wheel II 231. At this time, the user then opens the upper swing handle 510 and the lower swing handle 520 of the handle 500. Since the driven sliding ratchet wheel I 222 in the ratchet unit I 220 disengages from the meshing with the driving fixed ratchet wheel I 221, therefore, the driven sliding ratchet wheel I 222 cannot act on the cutting rotation driving mechanism 300 to rotate. However, the driving fixed ratchet wheel I 221 can drive the driving fixed ratchet wheel II 231 to rotate through the transmission gear 240. And under the dual action of the stopper portion 612 and the ratchet spring 250, the driving fixed ratchet wheel II 231 and the driven sliding ratchet wheel II 232 are tightly meshed and connected. Therefore, when the driving fixed ratchet wheel II 221 rotates, it can drive the driven sliding ratchet wheel II 232 to rotate through frictional pressure, so that the driven sliding ratchet wheel II 232 will not jump with the driving fixed ratchet wheel II 231. When the driven sliding ratchet wheel II 232 rotates, it will drive the transmission shaft 320 to rotate in the reverse direction (counterclockwise), thereby driving the tooth wheel rod 310 to rotate in the reverse direction (counterclockwise). When the tooth wheel rod 310 rotates in the reverse direction (counterclockwise), the axial unlocking of the tooth wheel rod 310 can be carried out through the pin 350, so that the biting distance between the tooth wheel disc 311 and the cutter wheel 420 increases. After the biting distance increases, the bitten can lid can be directly discarded, thereby realizing the automatic lid discarding function of the can opener.

[0058] In this embodiment, the reverse reset mechanism 600 can be arranged on the base 100 or on the handle 500, as long as the inclined pressing surface 611 and the stopper portion 612 of the pressing member 610 act on the driven sliding ratchet wheel I 222 and the driven sliding ratchet wheel II 232 respectively, and the elastic piece 620 can rebound and reset the pressing member 610. The specific position can be set according to the actual production requirements and is not limited here.
