[0026] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0027] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there may be an intervening element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. Conversely, when an element is said to be "directly on" another element, there is no intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] Please see Figure 1 and Figure 2A can-opening edge trimmer includes a main body 100, a drive unit 200 and a cutting unit 300 mounted on the main body 100. The drive unit 200 and the cutting unit 300 are in an interlocking state. The drive unit 200 includes a toothed rod 210, a bushing 220, a spring 230, a wedge sleeve 240 and a pin 250. One end of the toothed rod 210 is provided with a toothed disc 211, and the other end extends through the main body 100 and has a limiting hole 212. The bushing 220 and the spring 230 are respectively sleeved on the toothed rod 210 and located at the end where the toothed disc 211 is provided. The bushing 220 is close to the toothed disc 211, and the two ends of the spring 230 abut against the bushing 220 and the main body 100 respectively. The wedge sleeve 240 is sleeved on the extended end of the toothed rod 210, and the pin 250 is inserted into the limiting hole 212 to cooperate with the wedge sleeve 240.

[0030] Specifically, the drive unit 200 in this embodiment is mainly assembled from a roller rod 210, a bushing 220, a spring 230, a wedge sleeve 240, and a pin 250. This reduces the number of two butterfly springs and one gasket found in the prior art. By reducing the number of assembly parts in the drive unit 200, the accumulated error during assembly can be reduced, thereby improving the assembly accuracy of the drive unit 200 and ensuring the quality stability of the can opener. At the same time, by reducing the number of assembly parts in the drive unit 200, the production efficiency of the can opener can also be effectively improved, the production cost of the can opener can be reduced, and the service life of the can opener can be increased.

[0031] When opening the can, the can lid is placed between the drive unit 200 and the cutting unit 300, and the wedge sleeve 240 is rotated. When the wedge sleeve 240 rotates, it acts on the pin 250. Through the cooperation between the pin 250 and the wedge sleeve 240, the toothed rod 210 is driven to move axially, thereby reducing the engagement distance between the drive unit 200 and the cutting unit 300 and locking the can lid. Then, the wedge sleeve 240 continues to drive the toothed rod 210 to rotate, thereby causing the cutting unit 300 to cut around the can lid and complete the cutting directly. After cutting, the wedge sleeve 240 is rotated in the opposite direction, and the pin 250 also rotates in the opposite direction. With the reaction force of the spring 230, the toothed rod 210 is moved axially and reset.

[0032] In addition, this embodiment replaces the steel wedge sleeve 240 in the prior art with a wedge sleeve 240 made of engineering plastic material, which can effectively reduce production costs. Since the plastic material itself has a certain elasticity, the plastic wedge sleeve 240 can bear the elasticity when opening the can, replacing the two butterfly springs in the prior art, thereby improving assembly accuracy. It can also enable the can opener to open both thicker and thinner can lids, improving the user experience.

[0033] Meanwhile, by replacing the bushing 220 and spring 230 in the existing technology, the bushing 220 is brought closer to the gear disc 212. The bushing 220 can effectively improve the stress strength of the gear disc 212, thereby increasing the overall service life of the gear rod 210. Furthermore, replacing the original steel bushing 220 with a bushing 220 made of engineering plastic material can also effectively reduce production costs.

[0034] Furthermore, in this embodiment, both the limiting hole 212 and the pin 250 are square, and the limiting hole 212 is made by wire cutting. The circular limiting hole 212 made by drilling in the prior art is changed to a square limiting hole 212 made by wire cutting, which can improve the accuracy of the limiting hole 212 and facilitate the processing of the limiting hole 212.

[0035] In this embodiment, in order to drive the can opener to cut around the can lid, a number of teeth are distributed on the toothed disc 211. The teeth provide torque to the toothed rod 210 so that the toothed rod 210 can rotate around the can lid. The number of teeth is 28-36, which can effectively reduce the torque. When the toothed disc 211 rotates, the tooth marks produced by the front and rear teeth of the toothed disc 211 can overlap, thereby reducing misalignment and slippage, and reducing the generation of burrs.

[0036] Since the wedge sleeve 240 needs to rotate during the can opening process, and in order to reduce the wear between the wedge sleeve 240 and the main body 100, a gasket 260 is also provided at the extension end of the toothed rod 210. The gasket 260 is located between the main body 100 and the wedge sleeve 240. The gasket 260 can effectively reduce the wear of the wedge sleeve 240, thereby improving the service life of the can opener.

[0037] Please see Figure 3 In order to achieve axial movement of the toothed rod 210, in this embodiment, there are two protruding limiting arms 241 at the end of the wedge sleeve 240. The two limiting arms 241 are arranged opposite to each other, and an inclined guide slope 242 is formed between the two limiting arms 241. When can opening is required, the wedge sleeve 240 is rotated. As the wedge sleeve 240 rotates, the two ends of the pin 250 move from the lowest end to the highest end of the guide slope 242. The movement of the pin 250 drives the roller rod 210 to move axially, thereby reducing the engagement distance between the roller disc 211 and the cutting unit 300. After the roller rod 210 moves axially, it can continue to be driven to rotate through the limiting arm 241. After cutting is completed, the wedge sleeve 240 is rotated in the opposite direction, and the two ends of the pin 250 move from the highest end to the lowest end of the guide slope 242. The roller rod 210 is axially reset under the action of the spring 230, thereby increasing the engagement distance between the roller disc 211 and the cutting unit 300.

[0038] Please see Figure 3 and Figure 4 To facilitate the use of the can opener, in this embodiment, the drive unit 200 further includes a knob 270, which is fitted onto the wedge sleeve 240. The wedge sleeve 240 has a first snap-fit ​​groove 243 and a first snap-fit ​​strip 244 on its side wall. The knob 270 has a second snap-fit ​​strip 271 and a second snap-fit ​​groove 272 inside its sleeve hole. By inserting the second snap-fit ​​strip 271 into the first snap-fit ​​groove 243 and the first snap-fit ​​strip 244 into the second snap-fit ​​groove 272, the knob 270 can be connected to the wedge sleeve 240. This makes the assembly between the knob 270 and the wedge sleeve 240 convenient and simple, and the wedge sleeve 240 can be rotated by the knob 270, making it convenient to use the can opener.

[0039] Please see Figure 1 and Figure 2 In order to cut the can lid, the cutting unit 300 in this embodiment includes a cutter shaft 310, a support roller 320 and a cutter wheel 330. An installation groove 110 is provided on the main body 100. The cutter shaft 310 passes through the installation groove 110. The support roller 320 and the cutter wheel 330 are respectively sleeved on the cutter shaft 310 and located in the installation groove 110. The support roller 320 and the cutter wheel 330 are both made by stamping process.

[0040] By setting the support roller 320 and the cutter wheel 330 in the mounting groove 110 of the main body 100 and fixing them with the cutter wheel shaft 310, and by having the cutter wheel 330 cooperate with the toothed wheel disc 211 of the toothed wheel rod 210, the can lid can be cut. At the same time, the existing one-piece cutter wheel is split into a separate cutter wheel 330 and support roller 320. The support roller 320 and the cutter wheel 330 are respectively manufactured by stamping and then precision machining on a lathe. This makes it easier to process the support roller 320 and the cutter wheel 330, thereby improving the processing efficiency of the cutter wheel 330 and the support roller 320 and reducing production costs.

[0041] Finally, please see Figure 1 To facilitate the use of the can opener, in this embodiment, an auxiliary positioning ring 120 is provided on the main body 100. The auxiliary positioning ring 120 can help cut the can lid. At the same time, a handle 400 is also inserted into the main body 100. Specifically, a insertion groove 130 is provided on the main body 100, and a plug 410 is provided on the handle 400. Inserting the plug 410 into the insertion groove 130 can connect the handle 400 to the main body 100. The handle 400 can also make it convenient for the user to hold the can opener, thereby facilitating the use of the can opener and improving the user experience.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description; however, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model; furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
