Description

Technical Field

[0001] The utility model relates to a cigar puncher for punching holes at the end of a cigar, in particular to a double-blade cigar puncher which is convenient for double-blade telescopic control. Background Art

[0002] A cigar punch is a general term for tools used to punch holes in the ends of cigars. The basic principle is to use the annular cutting edge of a cylindrical knife to align with the end of the cigar and screw it in to cut a circular through hole. When withdrawing, the cut part is taken out to connect the inside of the cigar with the outside world, making it easier for air to enter the cigar when smoking, so that continuous smoking can be achieved.

[0003] Traditional cigar punches mainly have a simple structure of one cylindrical knife. This simple cigar punch cannot meet the punching needs of cigars with different diameters. There are also traditional cigar punches with two cylindrical knives of different diameters, but the two cylindrical knives are connected to each other and their center lines do not overlap. One end of the two cylindrical knives is fixedly connected and the other end is separated. Although this structure has two cylindrical knives, it has obvious shortcomings in terms of ease of use and high-end product quality.

[0004] In order to solve the above problems, the applicant has applied for an invention patent with application number "202310056722.8" and name "Multifunctional cigar puncher", which was published on April 18, 2023. This invention patent application can realize the control of the extension and retraction of the large cylindrical knife and the small cylindrical knife respectively, and the center lines of the large cylindrical knife and the small cylindrical knife coincide with each other, with high integration, thus solving the above problems.

[0005] However, the above invention patent application still has the following defects: the control of the extension and retraction of the large cylindrical knife and the small cylindrical knife is achieved by the cooperation of structures such as the through hole, compression spring, ball bearing provided on the core shaft, the groove provided on the large knife mounting cylinder and the through hole on the small cylindrical knife. The structure involves many parts, the local structure is relatively complex, the processing and assembly are relatively cumbersome, which reduces the production efficiency, increases the production cost, and is more prone to failure; in addition, since the above structure needs to occupy the upper space of the core shaft, the length of the center hole of the core shaft is short, so the acupuncture length can only be short, which makes it inconvenient to use.

[0027] In order to enable the knife mounting cylinder 16 to move vertically relative to the upper section of the core shaft but not to rotate relative to the upper section of the core shaft, the hole wall surface of the central through hole of the knife cylinder bottom plate 18 is composed of two opposite knife cylinder vertical planes (not visible in the figure, but easy to understand) and two opposite knife cylinder arc surfaces (not visible in the figure, but easy to understand) arranged at intervals, and the side wall outer surface of the upper section of the core shaft is composed of two opposite core shaft vertical planes (not visible in the figure, but easy to understand) and two opposite core shaft arc surfaces (not visible in the figure, but easy to understand) arranged at intervals, the two knife cylinder vertical planes are in contact with the two core shaft vertical planes respectively, and the two knife cylinder arc surfaces are in contact with the two core shaft arc surfaces respectively.

[0028] In order to ensure that the large cylindrical knife 9 and the small cylindrical knife 12 stop moving upward after moving into position, the upper end hole wall of the central through hole of the cylindrical outer shell 1 is located above the internal thread on the outer shell and is provided with an outer shell circular step 7 for blocking the large knife mounting cylinder 13 from moving upward, and the middle hole wall of the central through hole of the large knife mounting cylinder 13 is located above the internal thread of the large knife cylinder and is provided with a large knife cylinder circular step 11 for blocking the small knife mounting cylinder 16 from moving upward.

The upper end of the second compression spring 10 contacts the top cover circular step 8, and the top cover 6 is located in the small cylindrical knife 12.

[0030] like Figure 1 and Figure 2As shown, when in use, the process of extending the large cylindrical knife 9 is as follows: hold the tail cover 3 with one hand and keep it still, and hold the cylindrical shell 1 with the other hand to rotate, and the rotation direction is to make the large knife mounting cylinder 13 move upward. In this process, since the thread direction of the large knife cylinder outer thread is opposite to that of the large knife cylinder inner thread, the rotation of the cylindrical shell 1 will cause the small knife mounting cylinder 16 to have a tendency to move downward, but since the lower end of the small knife mounting cylinder 16, i.e., the small knife cylinder bottom plate 18, is blocked by the core shaft convex ring 19 and cannot move downward, the rotation of the cylindrical shell 1 can only make the large knife mounting cylinder 13 overcome the elastic force of the first compression spring 20 and move upward, thereby realizing the extension function of the large cylindrical knife 9, and the small knife mounting cylinder 16 remains in the initial position; when the large knife mounting cylinder 13 and the large cylindrical knife 9 move upward to the maximum position, The upper end of the large knife mounting cylinder 13 is blocked by the annular step 7 of the cylindrical shell 1 and cannot continue to move upward. At this time, the large cylindrical knife 9 can be used to punch the end of the cigar; after the punching is completed, the cylindrical shell 1 is rotated in the opposite direction (relative to the direction of the first rotation of the cylindrical shell 1). At this time, the large knife mounting cylinder 13 will move downward, and at the same time, the small knife mounting cylinder 16 has a tendency to move upward, but because the first compression spring 20 is compressed at this time and has a large elastic force, this elastic force makes the large knife mounting cylinder 13 have a large recovery force, which is obviously greater than the knife-out force of the small knife mounting cylinder 16, so the large knife mounting cylinder 13 and the large cylindrical knife 9 can move downward and reset normally, and at the same time, the small knife mounting cylinder 16 and the small cylindrical knife 12 remain motionless, thereby realizing the knife-collecting function of the large cylindrical knife 9.

[0031] The process of extending the small cylindrical knife 12 is as follows: hold the tail cover 3 with one hand and keep it still, and hold the cylindrical shell 1 with the other hand and rotate it in the opposite direction (relative to the direction of the first rotation of the cylindrical shell 1). During this process, the reverse rotation of the cylindrical shell 1 makes the broadsword mounting cylinder 13 tend to move downward, but at this time the lower end of the broadsword mounting cylinder 13 is blocked by the upper end of the shell positioning ring 2 and cannot move downward, so the cylindrical shell 1 will drive the broadsword mounting cylinder 13 to rotate in the opposite direction synchronously, so that the small knife mounting cylinder 16 overcomes the elastic force of the second compression spring 10 and moves upward, driving the small cylindrical knife 12 to move upward, realizing the extension function of the small cylindrical knife 12, and the broadsword mounting cylinder 13 remains in the initial position; when the small knife mounting cylinder 16 and the small cylindrical knife 12 move upward to the maximum position, the upper end of the small knife mounting cylinder 16 The knife mounting cylinder 13 is blocked by the annular step 8 of the knife barrel and cannot continue to move upward. At this time, the small cylindrical knife 12 can be used to punch the end of the cigar; after the punching is completed, the cylindrical shell 1 is rotated in the positive direction (relative to the direction of the first rotation of the cylindrical shell 1). At this time, the knife mounting cylinder 16 will move downward, and the knife mounting cylinder 13 has a tendency to move upward, but because the second compression spring 10 is compressed at this time and has a large elastic force, the elastic force makes the knife mounting cylinder 16 have a large recovery force, which is obviously greater than the knife-out force of the knife mounting cylinder 13, so the knife mounting cylinder 16 and the small cylindrical knife 12 can move downward and reset normally, and at the same time the knife mounting cylinder 13 and the large cylindrical knife 9 remain stationary, thus realizing the knife-collecting function of the small cylindrical knife 12.

[0032] If the need for acupuncture 15 is required, the acupuncture seat 4 is directly rotated to separate it from the core shaft 14, and the acupuncture assembly can be taken out. The acupuncture seat 4 is held by hand to use the acupuncture 15, and the acupuncture seat 4 is installed at the lower end of the core shaft 14 after use.
