Description

Technical Field

[0001] This invention relates to the field of hand tools, and more particularly to the field of pattern stamping technology, specifically to a rotating mechanism and stamping machine for stamping circular patterns. Background Technology

[0002] A stamping machine is a device that uses the pressure of two plates to transfer ink through the graphic portion onto a substrate. With a stamping machine, consumers can print their favorite designs on paper, clothing, or other stamping media. For example, Chinese invention patent application number CN201811045056.3 (publication number CN 109353135 A) discloses a stamping machine, including a body (1). The body (1) includes a base plate (2) for placing the substrate and the stamp, a pressure plate (3) that cooperates with the base plate (2) to press the substrate and the stamp, and a magnetic attraction structure (4) that generates mutual attraction between the pressure plate (3) and the base plate (2). The upper surface of the base plate (2) is provided with a working space (21) for placing the substrate and the stamp.

[0003] Compared to traditional manual stamping methods, the stamping machine disclosed in the aforementioned patent is easier to operate and can produce complete and uniform patterns. However, when users need to stamp circular text and / or patterns on the stamping carrier, this is generally achieved by manually rotating the stamping carrier. This method is not only cumbersome and inefficient, but the stamping carrier is also prone to displacement during the stamping process, resulting in the text or pattern not being accurately stamped to the required position, and thus failing to obtain the circular pattern desired by the user. Summary of the Invention

[0004] The first technical problem to be solved by the present invention is to provide a rotary mechanism for stamping circular patterns that is easy to use and has a good stamping effect, in contrast to the prior art.

[0005] The second technical problem to be solved by the present invention is to provide a rotating mechanism for stamping circular patterns with adjustable rotation levels, in contrast to the prior art.

[0006] The third technical problem to be solved by the present invention is to provide a stamping machine having the above-mentioned rotating mechanism, in contrast to the prior art.

[0007] The technical solution adopted by the present invention to solve at least one of the above-mentioned technical problems is as follows: a rotating mechanism for circular pattern stamping, characterized in that it includes a base, a rotating unit and an operating unit located on the rotating unit, wherein the rotating unit is disposed on the base and can rotate circumferentially relative to the base, the operating unit is detachably connected to the rotating unit, and a clamping space for holding the stamping carrier is formed between the rotating unit and the operating unit, and, in the rotating state of the operating unit, the operating unit, the rotating unit and the stamping carrier in the clamping space can rotate circumferentially synchronously relative to the base.

[0008] Furthermore, the top of the rotating unit has a first clamping plane, and the bottom of the operating unit has a second clamping plane. The first clamping plane and the second clamping plane are vertically opposite each other to form the aforementioned clamping space. The stamping carrier is generally a flat item such as paper, and the clamping space formed by the upper and lower planes can better hold the stamping carrier.

[0009] Furthermore, both the first and second clamping planes are circular in shape and their sizes are matched. The first and second clamping planes are vertically aligned, and the operating unit and rotating unit can rotate circumferentially around the central axis of the first and second clamping planes. This allows for better synchronous rotation of the operating unit, rotating unit, and stamping carrier.

[0010] Furthermore, a first magnetic suction element is embedded in the first clamping plane of the rotating unit, and a second magnetic suction element is embedded in the second clamping plane of the operating unit. The rotating unit and the operating unit are detachably connected through the mutual magnetic attraction of the first and second magnetic suction elements. This detachable connection facilitates easy assembly and disassembly, thereby simplifying the loading and unloading of the stamping carrier.

[0011] Furthermore, there are two first magnetic suction elements on the first clamping plane, and the two first magnetic suction elements are respectively located on both sides of the center of the first clamping plane. Correspondingly, there are also two second magnetic suction elements on the second clamping plane, which correspond one-to-one with the first magnetic suction elements. The two first magnetic suction elements have opposite magnetic properties, and each first magnetic suction element can form a magnetic connection with its corresponding second magnetic suction element. This can limit the relative assembly position of the operating unit and the rotating unit, thereby enabling more accurate assembly of the two.

[0012] Furthermore, the two first magnetic suction components are symmetrically arranged on both sides of the center of the first clamping plane, which enables stable assembly of the two while better achieving relative positioning between the operating unit and the rotating unit.

[0013] Furthermore, at least one of the first and second clamping planes is provided with an anti-slip pad. This increases the relative friction between each clamping plane and the stamping carrier, thereby enabling both to better drive the stamping carrier to rotate synchronously.

[0014] Furthermore, the operating unit includes a cylindrical operating knob, the bottom surface of which forms the second clamping plane, and an observation channel extending vertically along its central axis. An alignment structure is provided in the observation channel, which enables the alignment of selected points on the stamping carrier.

[0015] Furthermore, the alignment structure includes a cross-shaped alignment bracket, the center of which is located on the central axis of the aforementioned operating knob. The alignment bracket allows for positioning of the selected location on the stamping carrier, thereby ensuring the pattern is stamped in the correct position.

[0016] Furthermore, it also includes a rotation stop unit that allows the aforementioned rotating unit to rotate circumferentially relative to the base at a preset angle. This allows the user to obtain annular patterns at specific angular intervals as needed.

[0017] Furthermore, the rotary gear unit includes a gear shift ball, a gear shift groove into which the gear shift ball engages, and a gear shift spring. The rotary unit includes a disc-shaped rotating disk, with the gear shift ball disposed outside the rotating disk. The side of the rotating disk has an annular gear shift surface centered on the central axis of the rotating disk. The gear shift grooves are spaced circumferentially on the gear shift surface, and gear shift convex surfaces are formed at the gear shift surfaces between adjacent gear shift grooves. When the operating unit is rotated, the gear shift ball can slide circumferentially relative to the gear shift surface. When the gear shift ball is opposite to a gear shift groove on the gear shift surface, the gear shift ball engages in the gear shift groove, and the gear shift spring ensures that the gear shift ball always tends to move towards the gear shift surface. Thus, when the gear shift ball slides to the next gear shift groove, it can slide into the gear shift groove under the elastic force of the gear shift spring. The included angle between adjacent gear slot grooves is the included angle between repeating patterns in the annular pattern obtained by stamping. When the gear slot ball is inserted into the gear slot groove, the rotating disk stops rotating. At this time, the stamp stamps a pattern on the stamping carrier. As the gear slot ball slides along the gear slot annular surface, the stamp repeats the stamping in the circumferential direction to form an annular pattern.

[0018] Furthermore, the base has an upward-opening circular mounting groove. The rotating disk is fitted into this mounting groove and can rotate circumferentially relative to the base within the groove. The gear shift ring is located on the outer circumferential surface of the rotating disk. The base also has a first mounting channel matching the size of the gear shift ball. This mounting channel extends radially along the mounting groove and opens to the side wall of the groove. The gear shift ball is fitted into this first mounting channel and can move along its length. The gear shift spring is positioned between the gear shift ball and the inner end face of the first mounting channel. This design ensures stable installation of the gear shift ball and facilitates its sliding along the gear shift ring and into each gear shift groove sequentially.

[0019] Furthermore, the rotary gear unit includes a gear shift ball, a gear shift groove into which the gear shift ball is inserted, and a gear shift spring. The rotary unit includes a disc-shaped rotating disk, with the gear shift ball disposed outside the rotating disk. A circular mounting opening is provided on the base, and the rotating disk is fitted into the mounting opening and can rotate relative to the base within the mounting opening. Below the mounting opening is a mounting space communicating vertically with the mounting opening. The gear shift groove is formed on the bottom surface of the rotating disk, and the gear shift groove is circumferentially spaced around the center of the bottom surface of the rotating disk to form a gear shift ring. The gear shift ball and the gear shift spring are both disposed in the mounting space, wherein the gear shift ball and the gear shift ring are vertically aligned, and the gear shift spring causes the gear shift ball to always have a tendency to move towards the gear shift ring.

[0020] Furthermore, the aforementioned rotary gear unit also includes a gear arm horizontally disposed in the aforementioned installation space. The top surface of the gear arm has a vertically extending second mounting channel. The gear shift ball is embedded in the second mounting channel and can move up and down along the depth direction of the second mounting channel. The gear shift spring is positioned between the gear shift ball and the inner bottom surface of the second mounting channel. The gear shift ball moves along the gear ring. When the gear shift ball engages in the gear shift groove, the rotating disk stops rotating, and the stamp imprints a pattern on the stamping carrier. When the gear shift ball abuts against the gear shift convex surface, the gear shift spring is compressed, causing the gear shift ball to tend to move upwards. Thus, when the gear shift ball slides to the next gear shift groove, it can engage in the gear shift groove under the elastic force of the gear shift spring.

[0021] Furthermore, the gear shift grooves are evenly spaced along the circumference of the gear shift rings, and there are at least two gear shift rings arranged at intervals on the bottom surface of the rotating disk. The number of gear shift grooves on each gear shift ring is positively correlated with its circumference. The gear shift arm can move horizontally within the installation space, allowing the gear shift ball to be vertically aligned with the corresponding gear shift ring. By moving the gear shift arm to align the gear shift ball with different gear shift rings, the angle between adjacent repeating patterns in the stamped annular pattern can be changed.

[0022] Furthermore, a gear shift post is vertically arranged in the installation space. The gear shift arm is elongated in shape, and the first end of the gear shift arm is pivotally connected to the gear shift post. During the rotation of the gear shift arm around the gear shift post, the gear shift ball can move back and forth and be positioned between different gear shift rings, thereby realizing the rotation of the gear shift arm. As needed, the gear shift ball can be adjusted to be opposite to the corresponding gear shift ring to obtain a ring pattern with the required included angle.

[0023] Furthermore, two limit posts are vertically installed in the installation space, one on each side of the gear shift arm. When the gear shift arm abuts against one of the limit posts, the gear shift ball is aligned vertically with the gear shift ring with the shortest circumference. When the gear shift arm abuts against the other limit post, the gear shift ball is aligned vertically with the gear shift ring with the longest circumference. This limits the movement of the gear shift arm, preventing the gear shift ball from slipping out during gear shifting and being unable to slide between different gear shift rings. In addition, each limit post supports the rotating disk, allowing it to rotate more smoothly around the rotating post.

[0024] Furthermore, a rotating column is vertically arranged in the installation space, and a vertically downward extending rotating bushing is provided at the center of the bottom surface of the rotating disk. The rotating bushing is sleeved on the rotating column and can rotate relative to the rotating column, thereby enabling the rotating disk to rotate more smoothly.

[0025] Furthermore, the second mounting channel is located in the middle of the gear shift arm, and the gear shift post is located on one side of the rotating post. The middle of the gear shift arm is bent to one side in the horizontal direction to form a clearance groove for the rotating post to be inserted. The limiting post includes a first vertical post and a second vertical post. There are two first vertical posts, which are respectively located on both sides of the first end of the gear shift arm, and there are also two second vertical posts, which are respectively located on both sides of the second end of the gear shift arm. This allows for better limiting of the rotation of the gear shift arm, and further better limiting of the movement of the gear shift ball between different gear shift rings, ensuring the accuracy of the gear shifting action.

[0026] Furthermore, the installation space includes a limiting annular surface corresponding to the rotation trajectory of the gear shift arm. This limiting annular surface has limiting grooves that correspond one-to-one with the gear shift rings. The second end of the gear shift arm has a protruding elastic limiting protrusion, which can slide along the limiting annular surface and engage with each limiting groove. On one hand, the engaging action of the elastic limiting protrusion with the corresponding limiting groove allows the gear shift arm to be positioned at the desired gear; on the other hand, it facilitates gear shifting operations for the user.

[0027] Furthermore, the base has a hollow structure, with its inner cavity forming the aforementioned installation space. The mounting opening is located on its top wall. The gear shift post, each limiting post, and the limiting groove are respectively formed on the inner bottom surface of the base. An operating opening is located on the side wall of the base, and the second end of the gear shift arm protrudes through this operating opening, forming an operating end for hand operation. This simplifies the internal structure of the base and makes gear shifting more convenient for the user.

[0028] The technical solution adopted to further solve the third technical problem mentioned above is: a stamping machine, including a base plate and a cover plate disposed on the base plate, characterized in that it has a rotating mechanism for stamping annular patterns as described above.

[0029] Furthermore, the rotating mechanism and the aforementioned base plate are either an integral part or detachably connected. The integral structure ensures the structural stability of both the rotating mechanism and the base plate, while the detachable connection allows the rotating mechanism to be connected to different types of base plates, meeting user needs.

[0030] Compared with the prior art, the advantages of the present invention are as follows: a clamping space is formed between the rotating unit and the operating unit. Since the rotating unit and the operating unit are detachably connected, it is convenient to place the stamping carrier in the clamping space. Furthermore, when the operating unit is rotating, the operating unit, the rotating unit, and the stamping carrier in the clamping space can rotate synchronously circumferentially relative to the base. That is, rotating the operating unit can realize the rotation of the stamping carrier, thereby realizing repeated circumferential stamping on the stamping carrier to form the desired annular pattern. Compared with the manual method, the present invention can realize the automatic rotation of the stamping carrier through the operating unit, which is convenient to operate. Moreover, the clamping and positioning by the operating unit and the rotating unit can prevent the stamping carrier from shifting during the stamping process, thereby ensuring the accuracy of the stamping position and the quality of the stamped pattern.

[0049] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0050] Example 1:

[0051] like Figures 1-8 As shown, a stamping machine for stamping circular patterns includes a base plate 2 and a cover plate 1 disposed on the base plate 2. The cover plate 1 and the base plate 2 are used to hold the stamp (generally made of silicone or rubber, with text and / or patterns on one side) and the stamping carrier (paper in this embodiment). In this embodiment, both the cover plate 1 and the base plate 2 are square plates, and a rotating mechanism 3 is provided at one end of the base plate 2.

[0052] Furthermore, the aforementioned rotating mechanism 3 includes a base 4, a rotating unit 5, and an operating unit 6 located on the rotating unit 5. The rotating unit 5 is mounted on the base 4 and can rotate circumferentially relative to the base 4. The operating unit 6 is detachably connected to the rotating unit 5, and a clamping space for holding the stamping carrier is formed between the rotating unit 5 and the operating unit 6. Furthermore, when the operating unit 6 is rotating, the operating unit 6, the rotating unit 5, and the stamping carrier in the clamping space can rotate circumferentially synchronously relative to the base 4. In this embodiment, the base 4 and the base plate 2 are integral, i.e., one end of the base plate 2 extends outward to form the base 4, and the clamping space is used to hold the stamping carrier.

[0053] As can be seen from the above, a clamping space is formed between the rotating unit 5 and the operating unit 6. Since the rotating unit 5 and the operating unit 6 are detachably connected, it is convenient to place the stamping carrier in this clamping space. Furthermore, when the operating unit 6 is rotating, the operating unit 6, the rotating unit 5, and the stamping carrier in the clamping space can rotate synchronously circumferentially relative to the base 4. That is, rotating the operating unit 6 can realize the rotation of the stamping carrier, thereby achieving repeated circumferential stamping on the stamping carrier to form the desired annular pattern. Compared with the manual method, the present invention can realize the automatic rotation of the stamping carrier through the operating unit 6, which is convenient to operate. Moreover, the clamping and positioning by the operating unit 6 and the rotating unit 5 can prevent the stamping carrier from shifting during the stamping process, thereby ensuring the accuracy of the stamping position and the quality of the stamped pattern.

[0054] Furthermore, the top of the rotating unit 5 has a first clamping plane 50, and the bottom of the operating unit 6 has a second clamping plane 60. The first clamping plane 50 and the second clamping plane 60 are vertically opposite each other to form the clamping space. The stamping carrier is generally a flat item such as paper, and the clamping space formed by the upper and lower planes can better hold the stamping carrier. Preferably, the first clamping plane 50 and the second clamping plane 60 are both circular in shape and their sizes are matched. The first clamping plane 50 and the second clamping plane 60 are vertically opposite each other, and the operating unit 6 and the rotating unit 5 can rotate circumferentially around the central axis of the first clamping plane 50 and the second clamping plane 60, thereby better realizing the synchronous rotation of the operating unit 6, the rotating unit 5, and the stamping carrier.

[0055] There are various ways to achieve the detachable connection between the rotating unit 5 and the operating unit 6. In this embodiment, a first magnetic suction member 51 is embedded in the first clamping plane 50 of the rotating unit 5, and the exposed surface of the first magnetic suction member 51 is flush with or nearly flush with the first clamping plane 50. A second magnetic suction member 61 is embedded in the second clamping plane 60 of the operating unit 6, and the exposed surface of the second magnetic suction member 61 is flush with or nearly flush with the second clamping plane 60. The rotating unit 5 and the operating unit 6 are detachably connected through the mutual magnetic attraction of the first magnetic suction member 51 and the second magnetic suction member 61. The detachable connection between the rotating unit 5 and the operating unit 6 through magnetic attraction makes assembly and disassembly convenient, thereby facilitating the loading and unloading of the stamping carrier. Specifically, there are two first magnetic suction members 51 on the first clamping plane 50, and the two first magnetic suction members 51 are symmetrically arranged on both sides of the center of the first clamping plane 50. Correspondingly, there are also two second magnetic suction members 61 on the second clamping plane 60, which correspond one-to-one with the first magnetic suction members 51. The two second magnetic suction members 61 are symmetrically arranged on both sides of the center of the second clamping plane 60, and the two first magnetic suction members 51 have opposite magnetic properties. Each first magnetic suction member 51 can form a magnetic attraction connection with the corresponding second magnetic suction member 6152. This can limit the relative assembly position of the operation unit 6 and the rotation unit 5, thereby enabling more accurate assembly of the two. In this embodiment, each first magnetic suction member 51 and each second magnetic suction member 61 is a magnet. Of course, one can be a magnet and the other can be an iron sheet.

[0056] Preferably, at least one of the first clamping plane 50 and the second clamping plane 60 is provided with an anti-slip pad 52. The anti-slip pad 52 increases the friction between each clamping plane and the stamping carrier, thereby allowing them to better drive the stamping carrier to rotate synchronously. In this embodiment, the anti-slip pad 52 is disposed on the first clamping plane 50, and there are two anti-slip pads 52, circumferentially spaced from the two first magnetic suction members 51. Preferably, each second magnetic suction member 61 is surrounded by an anti-slip washer 611.

[0057] Specifically, the aforementioned operating unit 6 includes a cylindrical operating knob 62. The bottom surface of the operating knob 62 forms the aforementioned second clamping plane 60, and an observation channel 621 extending vertically along its central axis is provided on the operating knob 62. An alignment structure is provided in the observation channel 621. In this embodiment, the alignment structure is a cross-shaped alignment frame 63, and the center of the alignment frame 63 is located on the central axis of the operating knob 62. The alignment frame 63 can be used to position the selected point on the stamping carrier, thereby enabling the pattern to be stamped to the correct selected position.

[0058] To allow users to obtain annular patterns with specific angular intervals, a rotating gear unit 7 can be further added, enabling the rotating unit 5 to rotate uniformly around the base 4 at a preset angle. In this embodiment, the gear unit 7 includes a gear ball 71, a gear groove 531 into which the gear ball 71 is inserted, and a gear spring 73. The rotating unit 5 includes a disc-shaped rotating disk 53. The gear ball 71 is disposed outside the rotating disk 53. The side of the rotating disk 53 has an annular gear surface 530 centered on the central axis of the rotating disk 53. The gear grooves 531 are evenly spaced around the gear surface 530, and gear convex surfaces 532 are formed at the gear surface 530 between adjacent gear grooves 531. When the aforementioned operating unit 6 is in a rotating state, the aforementioned gear shift ball 71 can move circumferentially relative to the gear shift ring surface 530. When the gear shift ball 71 is opposite to the gear shift groove 531 on the gear shift ring surface 530, the gear shift ball 71 is engaged in the gear shift groove 531. When the gear shift spring 73 abuts against the gear shift convex surface 532, the aforementioned gear shift spring 73 is compressed, causing the gear shift ball 71 to tend to move towards the gear shift ring surface 530. Thus, when the gear shift ball 71 slides to the next gear shift groove 531, the gear shift ball 71 can slide into the gear shift groove 531 under the action of the elastic force of the gear shift spring 73. The included angle between adjacent gear grooves 531 is the included angle between repeating patterns in the annular pattern obtained by stamping. When the gear ball 71 is inserted into the gear groove 531, the rotating disk 53 can remain stationary without external force. At this time, the stamp stamps a pattern on the stamping carrier. As the stamping carrier rotates around the axis under the drive of the rotating mechanism 3, the stamp can repeatedly stamp on the stamping carrier to form an annular pattern.

[0059] In this embodiment, the included angle between adjacent gear grooves 531 is 15° (that is, an annular pattern with an included angle of 15° can be obtained). By controlling the sliding distance of the gear ball 71 along the gear ring surface 530, annular patterns with included angles of 2×15°, 3×15°, 4×15°, 5×15°, 6×15°, etc. can be obtained respectively.

[0060] Furthermore, the base 4 has an upward-opening circular mounting groove 41. The rotating disk 53 is fitted into the mounting groove 41 and can rotate circumferentially relative to the base 4 within the mounting groove 41. The gear shift ring surface 530 is located on the outer circumferential surface of the rotating disk 53. The base 4 has a first mounting channel 42 that matches the size of the gear shift ball 71. The first mounting channel 42 extends radially along the mounting groove 41 and opens to the side wall of the mounting groove 41. The gear shift ball 71 is fitted into the first mounting channel 42 and can move along the length direction of the first mounting channel 42. The gear shift spring 73 is limited and installed between the gear shift ball 71 and the inner end face of the first mounting channel 42. This design ensures the stable installation of the gear shift ball 71 and facilitates the sliding of the gear shift ball 71 along the gear shift ring surface 530 and into each gear shift groove 531 in sequence.

[0061] Furthermore, in this embodiment, positioning holes 11 are respectively provided on both sides of the end of the cover plate 1 away from the rotating mechanism 3, and the bottom plate 2 is respectively provided with first elastic positioning posts 21 that can be inserted into the corresponding positioning holes 11. When the cover plate 1 is pressed down, each first elastic positioning post 21 is compressed, causing the cover plate 1 to tend to move upward. At the same time, second elastic positioning posts 12 are respectively provided on both sides of the bottom surface of the other end of the cover plate 1. When the cover plate 1 is pressed down, each second elastic positioning post 12 also causes the cover plate 1 to tend to move upward.

[0062] During the stamping process, the stamping carrier is first placed on the upper surface of the base plate 2, with one end of the carrier clamped in the clamping space. The stamp is placed at the desired stamping position, the cover plate 1 is closed, and after positioning, it is pressed down, compressing each elastic positioning post, causing the stamp to adhere to the lower surface of the cover plate 1. The pressure applied to the cover plate 1 is released, and the cover plate 1 returns to its original upward position under the elastic force of the positioning posts. The cover plate 1 is then lifted, and the required ink is applied to the stamp. The cover plate 1 is closed again, positioned, and then pressed down, compressing each elastic positioning post, and the pattern on the stamp is evenly imprinted on the stamping carrier. The operating unit 6 is rotated synchronously with the rotating unit 5 and the stamping carrier. When the desired position is reached, the rotating unit 6 is stopped, and the cover plate 1 is pressed down, imprinting the pattern on the stamp onto the stamping carrier again. This process is repeated until a 360° rotation is achieved, resulting in the desired circular pattern.

[0063] Example 2:

[0064] like Figure 9 and Figure 10As shown, unlike Embodiment 1, the rotating mechanism 3 in this embodiment is detachably connected to the base plate 2. That is, the base 4 of the rotating mechanism 3 is detachably connected to one end of the base plate 2, so that different types of base plates 2 and cover plates 1 can be replaced as needed to meet the stamping requirements of different patterns. Specifically, in this embodiment, the inner end of the base 4 has a horizontally outwardly extending buckling protrusion 45, which has a buckling hole 451. The bottom surface of one end of the base plate 2 has an upwardly recessed buckling groove 21 for the buckling protrusion 45 to be engaged, and the buckling groove 21 has a vertically extending buckling protrusion 22 that can be engaged into the buckling hole.

[0065] Example 3:

[0066] like Figures 11-18 As shown, unlike Embodiment 1, in this embodiment, the base 4 has a circular mounting opening 43. The rotating disk 53 is fitted into the mounting opening 43 and can rotate relative to the base 4 within the mounting opening 43. Below the mounting opening 43 is a mounting space 40 that communicates vertically with the mounting opening 43. The gear position groove 531 is formed on the bottom surface of the rotating disk 53. The gear position groove 531 is evenly spaced around the center of the bottom surface of the rotating disk 53 to form a gear position ring 534. The gear position ball 71 and the gear position spring 73 are both disposed in the mounting space 40. The gear position ball 71 is vertically aligned with the gear position ring 534, and the gear position spring 73 ensures that the gear position ball 71 always tends to move towards the gear position ring 534.

[0067] Furthermore, the rotary gear unit 7 also includes a gear arm 74 horizontally disposed in the mounting space 40. The top surface of the gear arm 74 is provided with a vertically extending second mounting channel 741. The gear ball 71 is embedded in the second mounting channel 741 and can move up and down along the depth direction of the second mounting channel 741. The gear spring 73 is limited and installed between the gear ball 71 and the inner bottom surface of the second mounting channel 741. The gear shift ball 71 moves along the gear shift ring 534. When the gear shift ball 71 is engaged in the gear shift groove 531, the rotating disk 53 stops rotating, and the stamp imprints a pattern on the stamping carrier. When the gear shift ball 71 abuts against the gear shift convex surface 532, the gear shift spring 73 is compressed, causing the gear shift ball 71 to tend to move upward. Thus, when the gear shift ball 71 slides to the next gear shift groove 531, the gear shift ball 71 can be engaged in the gear shift groove 531 under the action of the elastic force of the gear shift spring 73.

[0068] Furthermore, the aforementioned gear position grooves 531 are evenly spaced along the circumference of the aforementioned gear position rings 534, and there are at least two gear position rings 534, spaced apart internally and externally on the bottom surface of the aforementioned rotating disk 53. The number of gear position grooves 531 on each gear position ring 534 is positively correlated with its circumference. The aforementioned gear position arm 74 can move horizontally within the aforementioned installation space 40, causing the aforementioned gear position ball 71 to be vertically aligned with the corresponding gear position ring 534, thereby achieving gear shifting. In this way, by moving the gear position arm 74 to align the gear position ball 71 with different gear position rings 534, the included angle between adjacent repeating patterns in the circular pattern obtained by stamping can be changed. Specifically, in this embodiment, there are five gear rings 534, and the gear arm 74 has five adjustable gears: 4th gear (angle of 90°), 6th gear (angle of 60°), 8th gear (angle of 45°), 12th gear (angle of 30°), and 24th gear (angle of 15°).

[0069] To better enable the rotation of the gear shift arm 74, a gear shift post 81 is vertically arranged in the installation space 40. The gear shift arm 74 is elongated, and the first end of the gear shift arm 74 is pivotally connected to the gear shift post 81. During the rotation of the gear shift arm 74 around the gear shift post 81, the gear shift ball 71 can move back and forth and be positioned between different gear shift rings 534, thereby adjusting the gear shift ball 71 relative to the corresponding gear shift ring 534 as needed to obtain the required annular pattern with the included angle.

[0070] Furthermore, in order to limit the movement of the gear shift arm 74 and prevent the gear shift ball 71 from slipping out during gear shifting and being unable to slide between different gear shift rings 534, the aforementioned installation space 40 is also vertically provided with limiting posts 91 and 92. There are two limiting posts 91 and 92, which are respectively set on both sides of the aforementioned gear shift arm 74. When the gear shift arm 74 abuts against one of the limiting posts 91 and 92, the aforementioned gear shift ball 71 is vertically aligned with the aforementioned gear shift ring 534 with the shortest circumference. When the gear shift arm 74 abuts against the other limiting post 91 and 92, the aforementioned gear shift ball 71 is vertically aligned with the aforementioned gear shift ring 534 with the longest circumference. In addition, a rotating column 82 is vertically arranged in the installation space 40, and a vertically downward extending rotating bushing 533 is provided at the center of the bottom surface of the rotating disk 53. The rotating bushing 533 is sleeved on the rotating column 82 and can rotate relative to the rotating column 82, thereby enabling the rotating disk 53 to rotate more smoothly.

[0071] Specifically, in this embodiment, the second mounting hole 741 is located in the middle of the gear shift arm 74, and the gear shift post 81 is located on one side of the rotating post 82. The middle of the gear shift arm 74 is bent to one side in the horizontal direction to form an avoidance groove 744 for the rotating post 82 to be inserted. The limiting posts 91 and 92 include a first vertical post 91 and a second vertical post 92. There are two first vertical posts 91, which are respectively located on both sides of the first end of the gear shift arm 74. There are also two second vertical posts 92, which are respectively located on both sides of the second end of the gear shift arm 74. This can better limit the rotation of the gear shift arm 74, and further better limit the movement of the gear shift ball 71 between different gear shift rings 534, ensuring the accuracy of the gear shifting action.

[0072] Furthermore, preferably, the installation space 40 is provided with a limiting annular surface 10 corresponding to the rotation trajectory of the gear shift arm 74. This limiting annular surface 10 has limiting grooves 101 corresponding one-to-one with the gear shift ring 534. The second end of the gear shift arm 74 is provided with an elastic limiting protrusion 742, which can slide along the limiting annular surface 10 and engage with each limiting groove 101. On one hand, the engaging engagement of the elastic limiting protrusion 742 with the corresponding limiting groove 101 can limit the gear shift arm 74 to the desired gear position; on the other hand, it facilitates gear shifting operations for the user using the gear shift arm 74. In this embodiment, the second end of the gear shift arm 74 is provided with an elastic sheet (e.g., a spring), the middle of which is bent downwards to form the elastic limiting protrusion 742. There are multiple ways to implement the installation space 40 in this invention. In this embodiment, the base 4 is a hollow structure, and its inner cavity constitutes the installation space 40. The installation opening 43 is provided on its top wall. The gear shift post 81, each limiting post 91, 92 and the limiting groove 101 are respectively opened on the inner bottom surface of the base 4. The side wall of the base 4 is provided with an operation opening 44. The end of the second end of the gear shift arm 74 is exposed in the operation opening 44 and forms an operation end 743 for hand operation. This makes the internal structure of the base 4 simple and makes it more convenient for users to switch gears.
