[0025] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] refer to Figure 1-Figure 7 An embodiment of the present invention provides a can opener, including a mounting plate 1 and an opening assembly 2 installed on one side of the mounting plate 1, the opening assembly 2 including a guide plate 21, a driving turntable 22 and a plurality of cutter heads 23, the guide plate 21 is fixedly mounted on the mounting plate 1 and is provided with a plurality of guide grooves 211, the guide grooves 211 extend from the inside to the outside, the cutter heads 23 are slidably arranged in the guide grooves 211 and can move along the guide grooves 211, the driving turntable 22 is rotatably mounted on the mounting plate 1, the driving turntable 22 is provided with an arc-shaped protrusion 221, when the driving turntable 22 rotates, the arc-shaped protrusion 221 abuts against the cutter head 23 and can push the cutter head 23 to move outward along the guide grooves 211.

[0027] The present invention has a simple structure. When in use, the opening component 2 is aligned with the opening of the can. By rotating the driving turntable 22, the arc-shaped protrusion 221 of the driving turntable 22 pushes the cutter head 23 to move along the guide groove 211 toward the outside of the guide plate 21. When the cutter head 23 moves to abut against the inner side of the opening of the can, the mounting plate 1 is rotated to rotate the opener as a whole. During the rotation process, the cutter head 23 cuts the upper cover of the can and cuts off the side wall of the upper cover to separate the upper cover from the can body, thereby realizing rapid opening of the cover. The invention is convenient and quick to use and can be applied to the scene where the pull ring of the can is damaged or the user is accustomed to using a large-diameter cup for drinking. In addition, the cutter head 23 can change the distance moved in the guide groove 211 according to the diameter of the opening position of the upper cover of different cans until it abuts against the inner wall of the upper cover. In this way, the cutter head 23 is suitable for cutting the upper covers of cans of different sizes and is more widely used.

[0028] refer to Figure 1 and Figure 2 Furthermore, a driven gear 24 is coaxially fixed to the driving turntable 22, a rotating shaft is fixed to the mounting plate 1, a driving swing arm 25 is provided on the rotating shaft sleeve, and the driving swing arm 25 is provided with an active gear 251 meshing with the driven gear 24. By swinging the driving swing arm 25 using the lever principle, a smaller force can be used to make the cutter head 23 exert a larger pressure on the inner wall of the upper cover, thereby improving the cutting efficiency.

[0029] It should be noted that the driving swing arm 25 in this embodiment is provided with a plurality of teeth at one end close to the driven gear 24 for engaging with the driven gear 24, thereby driving the driven gear 24 to rotate during the swinging of the driving swing arm 25, which helps to reduce parts and improve assembly efficiency.

[0030] Preferably, reference Figure 2 and Figure 4 The driving swing arm 25 is connected with a return spring 26, so that after the cutter head 23 cuts the upper cover, the driving swing arm 25 returns to its original position under the action of the return spring 26, so that the cutter head 23 is no longer continuously stressed and remains in close contact with the upper cover, making it easier to remove after cutting.

[0031] In order to improve the strength of the opener structure, the driving turntable 22 and the driven gear 24 in this embodiment are integrally formed.

[0032] Preferably, in order to facilitate the user to rotate the opener while holding the mounting plate 1, the cutter head 23 can be continuously stressed and closely attached to the upper cover to transmit pressure, the opener of this embodiment also includes a hand-held swing arm 3, one end of the hand-held swing arm 3 is hinged to the mounting plate 1, and the other end is connected to the position of the driving swing arm 25 away from the driven gear 24. When in use, the user places the palm of the hand on the opener mounting plate 1, and the four fingers except the thumb are supported on the hand-held swing arm 3, and the thumb is supported on the other side of the mounting plate 1 away from the hand-held swing arm 3. The entire palm is in a state of holding the opener mounting plate 1, and the opening component 2 is placed in the upper cover, and the other hand fixes the can. At this time, the four fingers forcefully press the hand-held swing arm 3, one end of the hand-held swing arm 3 rotates, and the other end pushes the driving swing arm 25 to rotate, thereby driving the driving turntable 22 to rotate, so that the cutter head 23 slides out of the guide groove 211 and is closely attached to the inner wall of the upper cover, and the mounting plate 1 is held tightly and the hand-held swing arm 3 is rotated to achieve cutting of the upper cover.

[0033] Furthermore, the driving turntable 22 includes a turntable body and a plurality of guide blades 222 arranged circumferentially along the turntable body. An arc-shaped protrusion 221 is formed on one side edge of the guide blades 222 , and an accommodating groove 223 is formed between two adjacent groups of guide blades 222 to facilitate accommodating the cutter head 23 .

[0034] Furthermore, the mounting plate 1 in this embodiment is provided with a sleeve 4 for being sleeved on the outside of the can, the sleeve 4 is coaxially arranged with the driving turntable 22, the opening assembly 2 is accommodated in the sleeve 4, and the upper cover is inserted into the sleeve 4 when in use, which is beneficial to maintain the stability of the position between the upper cover and the opening assembly 2 during the force cutting process of the upper cover. At the same time, the sleeve 4 helps to prevent the blade 23 from scratching the user, thereby improving the efficiency and safety of cutting.

[0035] refer to Figure 5-Figure 7 The cutter head 23 of this embodiment includes a cutting wheel 231. The outer circumference of the cutting wheel 231 is provided with a cutting cone 232 which is inclined from bottom to top and toward the axis of the cutting wheel 231. When the cutting wheel 231 cuts the inner wall of the upper cover, the inner wall of the upper cover is bent outward under the pressure of the cutting cone 232, so that the cut section of the upper cover connected with the can body after being cut and broken is bent inward, thereby preventing scratches on users and improving safety in use.

[0036] Specifically, in this embodiment, the angle between the cutting cone 232 and the axis of the cutting wheel 231 is 40°-60°, which is conducive to bending the cutting end surface of the upper cover after cutting to prevent scratches on the user.

[0037] Furthermore, the circumferential surface of the cutting wheel 231 in this embodiment is formed by two symmetrically arranged cutting cone surfaces 232, so that the cut sections of the two parts separated after the upper cover is cut are both bent.

[0038] Preferably, there are four groups of cutter heads 23, and the four groups of cutter heads 23 are evenly arranged along the circumference of the guide plate 21, so that the user can complete the circumference cutting of the upper cover by rotating the mounting plate 190°, which is convenient and quick to use.

[0039] In summary, the present invention has a simple structure. When in use, the opening component 2 is aligned with the opening of the can. By rotating the driving turntable 22, the arc-shaped protrusion 221 of the driving turntable 22 pushes the cutter head 23 to move along the guide groove 211 toward the outside of the guide plate 21. When the cutter head 23 moves to abut against the inner side of the opening of the can, the mounting plate 1 is rotated to rotate the opener as a whole. During the rotation, the cutter head 23 cuts the upper cover of the can and cuts off the side wall of the upper cover to separate the upper cover from the can body, thereby realizing rapid opening of the cover. The invention is convenient and quick to use and can be applied to scenarios where the pull ring of the can is damaged or the user is accustomed to using a large-diameter cup for drinking. In addition, the cutter head 23 can change the distance moved in the guide groove 211 according to the diameter of the opening position of the upper cover of the can until it abuts against the inner wall of the upper cover. In this way, the cutter head 23 is suitable for cutting upper covers of cans of different sizes and is more widely used.
