After clamping, the tightening sleeve 24 is fixed by the second locking screw 25 to prevent the clamp from loosening during the process of rotating the tank cover.

[0043] In this embodiment, the positioning and cutting structure 3 includes a positioning pin 31, a tool 32, and a screw; the positioning pin 31 is divided into a conical end and a cylindrical end, the cylindrical end is provided with a thread, and is connected to the first threaded hole 112 by threading. When cutting the can, the positioning pin 31 is inserted into the center of the can cover for positioning; the tool 32 is divided into a tip 321 and a blade body 322, which is connected to the slide rod 12 through a through hole 323 on the blade body 322. The slide rod 12 drives the tool 32 to move to adjust the cutting radius; when adjusting the cutting radius or torque magnification by pulling the slide rod 12, the tip 321 connected to the head of the slide rod 12 is used as a reference to determine the cutting radius or magnification at the current position; the maximum cutting radius of the positioning and cutting structure 3 depends on the distance between the side of the limit block 13 with the pin 131 and the positioning pin 31.

[0044] In this embodiment, a second threaded hole 121 is provided at the tail of the sliding rod 12, a second slot 122 is provided at the head, and four third threaded through holes 123 are provided on the side of the second slot 122; the tool 32 is inserted into the second slot 122, and the tool 32 is fixed to the sliding rod 12 by threaded connection between the screw 33 and the four third threaded through holes 123.

[0045] In this embodiment, the bottle opener 4 includes a screw rod 41 and a working area 42 connected to the screw rod 41, and a fourth notch 43 is provided on the working area 42; the screw rod 41 is connected to the slide rod 12 through a second threaded hole 121; the bottle opener 4 and the slide rod 12 are fixed together by cooperating with the screw rod 41 and the second threaded hole 121, and the bottle cap of the wine beverage can be opened by utilizing the lever principle through the fourth notch 43 of the working area 42, and the torque can also be adjusted by adjusting the position of the slide rod 12; in addition, the bottle opener 4 can also be used as a handle to pull the slide rod 12 to move, thereby adjusting the cutting radius or torque ratio.

[0046] In this embodiment, the fixed elastic clamp 21 comprises a short threaded rod 211 and a first elastic ring 212; the movable elastic clamp 22 comprises a long threaded rod 221 and a second elastic ring 222. The elastic ring is a curved ring with good elasticity and a rough inner surface. As the clamping force increases, the opening of the elastic ring expands and fits tightly against the side of the can lid, improving the tightening effect and preventing loosening between the clamp and the can lid during operation.

[0047] In this embodiment, the short threaded rod 211 passes through the first threaded through hole 211 outward from one side of the working area 42 when the opener performs a clamping operation, and the elastic clamp 21 is fixed by the fastening nut 23; the long threaded rod 221 passes through the first straight hole 113.

[0048] In this embodiment, the main body of the tightening sleeve 24 is a cylinder, with a handle 242 connected to the head, and an internal threaded hole 241 provided inside the cylinder; the tightening sleeve 24 is placed along the second straight hole 114 and is engaged with the long threaded rod 221 through a threaded connection. By rotating the handle 242, the rotational motion can be converted into the linear motion of the mobile elastic clamp 22, thereby achieving the clamping operation of the can lid; when the tightening sleeve 24 is clamping the can lid or is idle, the second locking screw 25 should be tightened through the second threaded through hole 115 to fix the tightening sleeve 24 and prevent it from falling off. The multifunctional opener can realize the effortless opening of the bottle cap of wine and beverage through the bottle opener 4; the cutting radius can be adjusted by the positioning and cutting structure 3 to safely cut cans of most diameters; the elastic clamp can adapt to clamping iron can lids of different diameters, and the tightening sleeve 24 provides a stable clamping force. At the same time, the torque adjustment mechanism can adjust the length of the force arm, making it more effortless to handle can lids of various diameters.

[0049] When using the bottle opener 4 to open a bottle cap of a beverage or alcoholic beverage, one only needs to ensure that the bottle opener 4 can contact the bottle cap. If not, adjust the position of the slide bar 12 and extend the lever arm. Then, the lower edge of the fourth notch 43 of the working area 42 is inserted into the bottom of the bottle cap, and the upper edge presses against the upper surface of the bottle cap. Hold the bottle body with your left hand and the main body of the opener with your right hand, and use the principle of leverage to pry the bottle cap upward.

[0050] When using the positioning and cutting mechanism 3 to open a can, facing a ring-pull can, first insert the conical end of the positioning ejector pin 31 into the center of the can lid. Then, loosen the first locking screw 14, pull the slide bar 12, adjust the cutter 32 to the appropriate cutting position, tighten the screw 33 to fix the position of the cutter 32, and then slightly force the tip of the cutter 321 to cut into the can lid. Hold the opener body and rotate it around the positioning ejector pin 31 as the center of the circle to remove the can lid. Loosen the locking screw and tighten it again after the reset is completed.

[0051] When using the clamping structure 2 to unscrew the can lid, facing the sealed screw-cap can, first loosen the second locking screw 25, then rotate the tightening sleeve 24, and roughly adjust the movable elastic clamp 22 to a position where the distance from the fixed elastic clamp 21 is close to the diameter of the can lid. Then place the can lid between the two clamps and continue to rotate the tightening sleeve 24. Under the action of the thrust, the curvature of the elastic ring is expanded by the bottle cap and eventually approaches the diameter of the bottle cap, thereby clamping the can lid. Then tighten the locking screw to prevent the clamp from loosening.

[0052] Loosen the first locking screw 14, pull the slide bar 12 outward, adjust it to a specific magnification scale, and tighten the locking screw to prevent the extended lever arm from sliding.

[0053] Finally, hold the can body with one hand and the extended lever arm with the other hand, and rotate it with force to complete the can opening with less force. After completing the can opening operation, reset the parts of the opener.

[0054] The device can be widely applied to the opening needs of different kinds of cans or bottles by adjusting the cutting radius or the size of the force arm according to the actual use requirements.

[0055] Example 2

[0056] This embodiment provides an assembly method of the above-mentioned mouth opener; Figure 3a and Figure 3b As shown, the structure diagram of the base 11. The base 11 in the opener frame 1 is connected to the slide rod 12 of the torque adjustment mechanism. The slide rod 12 is inserted into the slide groove 116 at the tail of the base 11 through the slide groove 116. The slide rod 12 slides back and forth through the slide groove 116 to adjust the torque and lever arm of the opener.

[0057] The limit block 13 is matched with the slide bar 12 to ensure that the first notch 134 on the limit block 13 is correctly connected to the slide bar 12. In the idle stage, the limit block 13 is fixed in place by the locking screw to prevent the slide bar 12 from causing the tool 32 to slide and cause damage.

[0058] The fixed elastic clamp 21 and the movable elastic clamp 22 are connected to the first straight hole 113 and the threaded through hole of the base 11. The fixed elastic clamp 21 consists of a short threaded rod 211 and an elastic ring, and the curvature can be adjusted as needed. The movable elastic clamp 22 is connected to the tightening sleeve 24 via a threaded connection. Rotating the tightening sleeve 24 drives the movable elastic clamp 22 in linear motion, adjusting the clamping degree.

[0059] Positioning ejector pin 31 is installed in the threaded hole on substrate 11 surface, and when in use, it is inserted into the circle center of the tank lid, so that auxiliary cutting is carried out. Then, cutter 32 is connected to slide bar 12 by screw 33.

[0060] Finally, the screw rod 41 of the bottle cap opener 4 is matched with the threaded hole on the slide rod 12 to ensure its stable installation, thereby completing the assembly of the multifunctional opener.

[0061] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible.
