The structure of the traditional bottle cap is shown in figure 1, and comprises a cap body, an anti-theft ring and a tangent line. When the cover is opened, the cover torque force is applied, and the cover body rotates until the cover body is broken at a tangent line with the anti-theft ring, so that the bottle cover is opened. In life, the torque force of the broken anti-theft ring is required to be large enough to open the bottle cap. Sometimes, people unscrew the bottle cap a little first, so that the connection between the cap body and the anti-theft ring is exposed, then the bottle cap is cut off at a tangent line by a nail clipper, more than half of the bottle cap is cut off, and then the bottle cap is screwed again, so that less effort is required. In addition, the plastic bottle caps used by some manufacturers have different material quality, different cutting sizes of the anti-theft ring tangent lines of the bottle caps, and different cap opening torque forces. This brings inconvenience to the life of people.

Detailed Description
The utility model is further described in connection with the following detailed description, which is a further illustration of the principles of the utility model and not in any way limiting the utility model. The same or similar techniques as those used in the present utility model are not beyond the scope of the appended claims.
Referring to fig. 1-6, a portable bottle cap opening device: comprises a spiral fastening ring 4 and a shell 5; the outer side of the spiral fastening ring 4 is provided with left-handed external threads, and the inner side of the spiral fastening ring is used for being in contact with the cover body 1 of the bottle cover; a left-handed internal thread is arranged on the inner side of the shell 5; the left-handed external thread on the outer side of the spiral fastening ring 4 is matched with the left-handed internal thread on the inner side of the shell 5; the left-handed external threads on the outer side of the spiral fastening ring 4 and the left-handed internal threads on the inner side of the shell 5 are conical threads, and the inner diameter of the spiral fastening ring 4 can stretch out and draw back. The conical screw thread is used for reducing the inner diameter of the screw fastening ring 4 when the screw fastening ring 4 is fastened by screwing the outer shell 5 to the right and counterclockwise, so as to increase the friction force between the screw fastening ring 4 and the cover body 1.
For the bottle cap shown in fig. 1, the anti-theft ring 2 and the tangent line 3 are included, when the bottle cap is opened, the inner diameter of the spiral fastening ring 4 is slightly enlarged, the bottle cap is sleeved on the cap 1, then the shell 5 is held by hand and is forcefully screwed right, the shell 5 is screwed into the outer side of the spiral fastening ring 4 anticlockwise, and the inner diameter of the spiral fastening ring 4 is reduced. The right-handed friction force between the screw fastening ring 4 and the bottle cap body 1 drives the bottle cap to rotate right until the connection between the bottle cap body 1 and the anti-theft ring 2 is twisted off along the tangent line 3, and finally the bottle cap can be unscrewed.
As a preferred embodiment, the inner side of the screw tightening ring 4 is made of hard rubber, and is used as a contact surface with the cover 1 to increase friction between the screw tightening ring 4 and the cover 1.
In another preferred embodiment, referring to fig. 2, the spiral fastening ring 4 includes a fastening ring notch 6 as a space for the spiral fastening ring 4 to reduce its inner diameter. In the use process, when the shell 5 is screwed into the outer side of the spiral fastening ring 4 in a right-handed way to fasten the spiral fastening ring 4, the fastening ring notch 6 is slowly closed; the inner diameter of the screw tightening ring 4 is gradually reduced so as to increase the friction between the screw tightening ring 4 and the cover 1. In practice, the fastening ring notch 6 comprises a notch on the screw fastening ring 4 near one end of the anti-theft ring 2 of the bottle cap, and the notch may be a rectangular concave notch with a width of 1mm, so as to further leave a space for the screw fastening ring to reduce the inner diameter.
In a further preferred embodiment, referring to fig. 4 and 5, the housing 5 includes a telescopic rod 7, and the end of the housing 5 away from the screw fastening ring is a hand holding part; the telescopic rod 7 is embedded in the hand holding part and is used for increasing the arm of force for rotating the shell 5. In the use process, when the shell 5 is screwed in the right direction and the spiral fastening ring 4 is fastened at the outer side of the spiral fastening ring 4 in a anticlockwise manner, if the resistance is too large, the telescopic rod 7 can be pulled out, the arm of force for rotating the shell 5 is increased, and therefore the shell 5 is rotated more easily, and the bottle cap is opened.
In the above embodiment, the inner diameter of the screw tightening ring 4 is selected according to the size of the common mineral water bottle cap in the market. The inner side of the spiral fastening ring 4 is made of hard rubber material and is used for increasing friction force with the bottle cap; the outer side of the screw fastening ring 4 is provided with left-handed external threads and is matched with left-handed internal threads in the shell 5. The spiral running wire on the inner side of the shell 5 and the spiral running wire on the outer side of the spiral fastening ring 4 are conical threads, so that the inner diameter of the spiral fastening ring 4 can be reduced when the threads are fastened, and the friction force between the hard rubber and the bottle cap to be opened is increased.
When in use, the spiral fastening ring 4 is sleeved on the bottle cap body 1 to be opened, and then the shell 5 is screwed on the outer side surface of the spiral fastening ring 4 anticlockwise. Since the designed thread is a left-hand conical thread, the screw tightening ring 4 enters the outer shell 5 and contracts when rotating anticlockwise, so that the friction force between the screw tightening ring 4 and the bottle cap to be opened is increased. When the torque provided by the friction force is large enough, the connection between the bottle cap body 1 and the anti-theft ring 2 of the bottle cap to be opened is broken, and the bottle cap is opened.
In particular, the needle of the utility model is designed for opening the bottle cap with a right-handed thread structure. If the bottle cap with the left-handed thread structure is opened, the external thread of the screw fastening ring 4 and the internal thread of the shell 5 can be changed from left-handed threads to right-handed threads. Other modifications and substitutions readily devised by those skilled in the art from the teachings of this specification, including the modification of the external threads of the helical lacing wire 4 and the internal threads of the housing 5 to right-handed threads, are intended to be within the scope of the appended claims.
