DETAILED DESCRIPTION

[0012] The following is a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only a part of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0013] An inner cover bottle opener, characterized in that it comprises a first arm 1, a second arm 2, a metal sheet 7, and a rotating shaft 3, wherein the rear end 11 of the first arm is an upwardly open structure, and the rear end 12 of the second arm is a downwardly open structure, and the open structure is similar to a step-type structure, wherein the rear end 11 of the first arm is a downward step, and the rear end 12 of the second arm is an inverted step form, and the thickness of the first arm 1 is the same as that of the second arm 2, and the thickness of the two steps added together is the same as that of the first arm 1 and the second arm 2. The rear end 11 of the first arm and the rear end 12 of the second arm are arc-shaped structures, and a boss is arranged on the arc-shaped structure; when the opening is the largest in this embodiment, the boss contacts the other arm, thereby preventing the opening from being too large. A through hole is provided at the center of the arc-shaped structure. In this embodiment, the through hole is a countersunk hole, but it is also possible not to make a countersunk hole, as long as it is ensured that the rotating shaft 3 can be installed. The rotating shaft 3 is movably connected with the rear end 11 of the first arm and the rear end 12 of the second arm; after being connected with the rotating shaft, the first arm 1 and the second arm 2 intersect at the rotating shaft, and a spring mounting hole 13 is provided near the rear end 11 of the first arm and the rear end 12 of the second arm. The spring mounting hole 13 is provided on the inner side of the first arm 1 and the second arm 2, and the opening direction of the spring mounting hole 13 points to the other arm respectively. A spring 6 is installed in the spring mounting hole 13; this spring 6 can play the role of automatic opening. The metal sheet 7 is a long strip structure with a semicircular end and a rectangular end; the long strip structure is similar to the shape of a human fingernail, and the first arm 1 and the second arm 2 are both V-shaped structures, and the V-shaped structure is a V-shaped structure with an obtuse angle. The inner side of the V-shaped structure of the front end 14 of the first arm, i.e. the inner side of the obtuse angle structure, and the inner side of the V-shaped structure of the front end 15 of the second arm, i.e. the inner side of the obtuse angle structure, are both provided with a step lower than the upper plane and inclined downward. The first arm downwardly inclined step 9 is at the same height as the second arm downwardly inclined step 10, and is drilled with screw holes, the position of the screw holes must be ensured to be staggered with the position of the installed metal sheet; a metal sheet 7 is provided in the middle of the first arm downwardly inclined step 9, and the first arm metal sheet pressing plate 4 and the metal sheet 7 are fixed to the first arm downwardly inclined step 9 by the pressing plate screw 8; two metal sheets 7 are provided on the second arm downwardly inclined step 10, and the second arm metal sheet pressing plate 5 and the two metal sheets 7 are fixed to the second arm downwardly inclined step 10 by the pressing plate screw 8, and the metal sheet 7 on the first arm downwardly inclined step 9 and the metal sheet 7 on the second arm downwardly inclined step 10 form a triangular structure as a whole. The metal sheets 7 are made of steel sheets of equal length and the same shape. The inventors have found that a slight downward tilt of the metal sheet can better open the bottle and can also effectively avoid errors in processing and use. The metal sheet 7 installed by the first arm and the second arm forms a triangular structure. Since the triangle has stability, the bottle cap can be opened better and the bottle cap is not easy to fall off.

[0014] Furthermore, the rotating shaft 3 is an anti-loosening bolt. The rotating shaft 3 can also use a scissor shaft, a rivet, etc. to facilitate production and manufacturing, and the present invention uses an anti-loosening bolt.

[0015] Working principle: In this example, three metal sheets slightly tilted downward are inserted on the outer edge of the inner cover, and then the inner cover is pulled up. The reason why the metal sheets tilt downward is that it is difficult to keep the metal sheets parallel to the outer edge of the inner cover during production and use. If the metal sheets tilt upward, it will be more difficult to insert into the edge of the inner cover and damage the inner cover. This embodiment uses a clamp-shaped structure. During operation, hold the two ends of the clamp-shaped structure to facilitate force and lifting.

[0016] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
