Description

Technical Field

[0001] The invention belongs to the field of mahjong entertainment equipment, and relates to a mahjong machine, and in particular to an operating disk and a shuffling integrated system in the mahjong machine and a mahjong machine containing the integrated system. Background Art

[0002] An operating panel is usually provided in an automatic mahjong machine to allow the user to input operating instructions and / or view the use status. In addition, the shape of the operating panel is usually adapted to the mahjong push-in opening on the desktop, and the push-in opening is closed or opened by lifting and lowering. For example, when the operating panel rises, the gap between the operating panel and the push-in opening will be exposed, and the user pushes the mahjong tiles through the gap, and the mahjong tiles fall onto the shuffling plate below for shuffling; after the operating panel descends, it returns to a position flush with the desktop, closing the push-in opening.

[0003] The accuracy of the lifting and lowering position of the operating panel is very important to the user experience of the mahjong machine, especially the lowering position to close the push-in port. If the height is not appropriate when it descends to the end of the stroke, a gap will occur between the operating panel and the push-in port, which is not only unsightly, but also poses a risk of dust and debris falling in.

[0004] In order to facilitate the control of the descending position of the operating panel, there are some mahjong machines in the prior art that can limit the descending position of the operating panel. For example, CN201710626792.7 discloses a central lifting mechanism of a mahjong machine, in which a lifting rod limiter is provided on the lifting rod of the operating panel. Such a lifting rod limiter can limit the lifting rod, but its limit height is fixed, so it is not convenient to adjust the descending position of the operating panel during installation or maintenance. Summary of the invention

[0005] To solve the above problems, the present invention provides an operating disk and shuffling integrated system, which is arranged in a mahjong machine and is characterized in that it comprises: an operating disk mechanism, a shuffling mechanism and a mounting seat, the operating disk mechanism comprises an operating disk that can be raised and lowered and an adjustment limit sleeve located below the operating disk and used to adjust the height of the operating disk when the operating disk is lowered, the shuffling mechanism comprises a shuffling disk that can rotate to shuffle mahjong cards and a fixing cap for fixing the shuffling disk, the mounting seat is provided with a first threaded portion and a second threaded portion located below the first threaded portion, the adjustment limit sleeve is threadedly connected to the first threaded portion, the fixing cap is threadedly connected to the second threaded portion, and an elastic snap-fit ​​structure is provided between the adjustment limit sleeve and the fixing cap for limiting the relative rotation of the two.

[0006] The operating panel and shuffling integrated system provided by the present invention may also have such technical features, wherein a plurality of longitudinally extending snap-fitting convex strips are distributed on the adjustment limit sleeve, an elastic sheet is connected to the fixing cap, a plurality of longitudinally extending snap-fitting grooves are provided on the inner side of the elastic sheet, and the snap-fitting grooves are engaged with the snap-fitting convex strips to form an elastic snap-fitting structure.

[0007] Furthermore, the above-mentioned operating disk and shuffling integrated system provided by the present invention may also have such technical features, wherein the lower end of the adjustment limit sleeve has an extension portion extending vertically downward, the locking convex strip extends at least on the extension portion, the fixing cap has a receiving groove for accommodating the extension portion, the outer wall of the receiving groove is provided with a recessed opening, and the elastic sheet is connected to the recessed opening.

[0008] In addition, the operating disk and integrated shuffling system provided by the present invention may also have such a technical feature that the thread directions of the first threaded portion and the second threaded portion are opposite.

[0009] In addition, the operating panel and shuffling integrated system provided by the present invention may also have such a technical feature, wherein a vertical pipe for supporting the operating panel is movably penetrated through the mounting seat.

[0010] Furthermore, the above-mentioned operating panel and shuffling integrated system provided by the present invention may also have such technical features, wherein the operating panel mechanism also has a lifting drive unit for lifting the operating panel, and the lifting drive unit includes a lifting drive seat fixedly installed at the bottom end of the vertical pipe, a lifting drive member having a drive block at one end that contacts the bottom surface of the lifting drive seat, and a lifting drive motor, and the other end of the lifting drive member is installed on the output end of the lifting drive motor.

[0011] In addition, the operating disk and shuffling integrated system provided by the present invention may also have such a technical feature, wherein the shuffling disk is rotatably mounted on the mounting seat through a bearing, has a bearing seat portion for mounting the bearing, and the lower surface of the fixing cap abuts against the upper surface of the inner ring of the bearing, thereby pressing the bearing into the bearing seat portion.

[0012] Furthermore, the above-mentioned operating disk and shuffling integrated system provided by the present invention may also have such a technical feature, wherein the pressing rotation direction of the fixing cap is the same as the rotation direction of the shuffling disk.

[0013] The present invention also provides a mahjong machine, characterized in that it comprises an operating disk and a shuffling integrated system as described above.

[0014] Function and Effect of the Invention

[0015] According to the operating panel and shuffling integrated system and mahjong machine provided by the present invention, since the mounting seat is provided with a first threaded portion and a second threaded portion, the adjusting limit sleeve is threadedly connected to the first threaded portion, the fixing cap is threadedly connected to the second threaded portion, and an elastic snap-fit ​​structure is provided between the adjusting limit sleeve and the fixing cap. When not subjected to external force, the two do not rotate relative to each other, but can rotate relative to each other when subjected to external force. Therefore, on the one hand, the height position of the adjusting limit sleeve can be maintained during normal use, so that the descending position of the control panel will not change. On the other hand, the adjusting limit sleeve can be rotated to adjust the limit height by simply twisting the adjusting limit sleeve to overcome the elastic force and disengage the elastic snap-fit ​​structure, that is, to adjust the height of the operating panel when it is descended. This adjustment process can be achieved without removing the control panel, so this adjustment during installation and maintenance is very easy to achieve. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0028] The specific implementation of the present invention is described below with reference to the accompanying drawings and embodiments.

[0029] <Example>

[0030] Figure 1 , Figure 2 It is a structural diagram of a mahjong machine according to an embodiment of the present invention.

[0031] like Figure 1-2 As shown, this embodiment provides a mahjong machine 100 for automatically shuffling and loading mahjong tiles 200, including a loading mechanism 101, an operating disk mechanism 102, a table frame mechanism 103 and a shuffling mechanism 107.

[0032] The table frame mechanism 103 includes an outer frame 104, a table top 105 mounted on the outer frame 104, and a table base 106 for supporting the table top 105 and other mechanisms. The bottom of the table base 106 is provided with table legs for supporting the ground, and the middle of the table top 105 is provided with a push-in port 1051 ( Figure 1 , Figure 2 The table legs are omitted. Figure 2 The outer frame 104 and the table top 105 are further omitted).

[0033] Figure 3 The present invention is a structural diagram of a mahjong machine in which a card loading mechanism is omitted.

[0034] like Figure 1-3 As shown, the operation panel mechanism 102 is located in the middle of the table 105, and has an operation panel 21 that can be raised and lowered and used for the user to input operation instructions, a support member for supporting the operation panel 21, a limit unit for limiting the height of the operation panel 21 when it is lowered, and a lifting and lowering driving unit for driving the lifting and lowering of the operation panel 21. The operation panel 21 is adapted to the shape of the push-in port 1051, and when it is not raised, it just closes the push-in port 1051, and when it is raised, the push-in port 1051 is exposed, so that the user can push the mahjong tiles 200 in.

[0035] The shuffling mechanism 107 is used to receive used mahjong tiles 200 and shuffle them, and includes a shuffling tray 71, a shuffling tray installation unit for installing the shuffling tray 71, a shuffling tray driving unit for driving the shuffling tray 71 to rotate, and a shuffling tray height adjustment unit for adjusting the height of the shuffling tray 71.

[0036] In the present invention, the mounting structure of the operating disk 21 and the mounting structure of the shuffling disk 71 are realized through a common mounting seat, whereby the operating disk mechanism 102, the shuffling mechanism 107 and the common mounting seat constitute an operating disk and shuffling integrated system.

[0037] The common mounting seat and the corresponding mounting structure are described below with reference to the accompanying drawings.

[0038] Figure 4 yes Figure 3 Longitudinal section view of the structure. Figure 5 yes Figure 3 The structural diagram of some components such as the shuffle plate and operating plate are omitted.

[0039] like Figure 3-5 As shown, the mounting seat 108 is the aforementioned common mounting seat, which is approximately cylindrical, and the upper end is provided with a first external thread portion 81 and a second external thread portion 82 from top to bottom, wherein the outer diameter of the first external thread portion 81 is smaller than the second external thread portion 82, and the thread directions of the first external thread portion 81 and the second external thread portion 82 are opposite. The mounting seat 108 is fixedly mounted on the table base 106. Specifically, the middle part of the table base 106 is recessed downward, and its size is slightly larger than the shuffle plate 71, so that the shuffle plate 71 can be accommodated in the recess. The bottom of the recess is a support plate 1061, and the mounting seat 108 is fixedly mounted at the middle position of the support plate 1061. In addition, a cover shell 1062 is also installed below the support plate 1061 of this embodiment, which is used to cover the periphery of the components below the support plate 1061 for shielding.

[0040] like Figure 4-5 As shown, the support member for supporting the operating panel 21 is a vertical pipe 22 , which is movably inserted into the mounting seat 108 , and the operating panel 21 is fixedly mounted on the top of the vertical pipe 22 .

[0041] Figure 6 1 is a structural diagram of a lifting drive unit according to an embodiment of the present invention.

[0042] like Figure 6 As shown, the lifting drive unit includes a lifting drive motor 231 , a lifting drive member 232 and a lifting drive seat 233 .

[0043] The lifting drive motor 231 is fixedly mounted below the support plate 1061 via a motor mounting bracket 2311 .

[0044] One end of the lifting drive member 232 is fixedly mounted on the output end of the lifting drive motor 231 , and the other end is provided with a driving block 2321 .

[0045] The lifting drive seat 233 is fixedly mounted at the bottom end of the vertical pipe 22, and its bottom surface contacts the driving block 2321. When the lifting drive member 232 rotates under the drive of the lifting drive motor 231, the end where the driving block 2321 is located can swing up and down, driving the vertical pipe 22 to rise or fall.

[0046] The operating panel limit unit includes an adjustment limit sleeve 24, which is in the shape of a truncated cone and has an internal thread on the inner surface, and is threadedly connected to the first external thread portion 81 through the internal thread. The upper end of the vertical pipe 22 passes through the fixed seat 108 and is located above the fixed seat 108, so that the operating panel 21 is located above the adjustment limit sleeve 24. When the operating panel 21 descends under the action of the lifting drive unit, the top of the adjustment limit sleeve 24 can contact the bottom of the operating panel 21 to limit the position of the operating panel 21 when it descends. By rotating the adjustment limit sleeve 24, the height position of the top of the adjustment limit sleeve 24 can be adjusted, thereby adjusting the high and low positions required when the operating panel 21 descends. The specific adjustment method will be described in detail later.

[0047] Figure 7 It is a structural diagram of a shuffle plate according to an embodiment of the present invention.

[0048] like Figure 7 As shown, the shuffling tray 71 includes a tray body 711, a sliding layer 712 and a plurality of blocking blocks 713. The tray body 711 has a sliding portion 7111, a card stopping portion 7112 and a card blocking portion 7113.

[0049] The sliding portion 7111 is in a truncated cone shape similar to a bamboo hat shape, and is located below the push-in port 1051, and is used to receive the mahjong tiles 200 dropped from the push-in port 1051 and allow the mahjong tiles 200 to slide thereon. The middle portion of the sliding portion 7111 is used to connect with the shuffle tray mounting unit, and is provided with a bearing seat portion 7114 that is recessed downward to form an annular groove. The cross section of the bearing seat portion 7114 is approximately L-shaped, and has a side wall extending downward from the inner edge of the sliding portion 7111 and a bottom wall extending horizontally inward from the side wall.

[0050] In this embodiment, the upper surface of the slide portion 7111 is inclined, that is, in a normal installation and use state, the height of the outer portion of the slide portion 7111 is lower than the height of the inner portion, and the angle of inclination is 30 degrees. When the mahjong tiles 200 are pushed in from the push-in entrance 1051, they can slide downward on the slide portion 7111, and this scattered sliding process has the effect of disrupting the mahjong tiles 200.

[0051] The stop sign portion 7112 is connected to the outside of the sliding portion 7111, and extends outwardly around the sliding portion 7111 to form a ring. In this embodiment, the upper surface of the inner portion of the stop sign portion 7112 (i.e., the portion connected to the sliding portion 7111) has a small inclination, while the outer portion has no inclination and is horizontal.

[0052] The blocking portion 7113 is disposed on the outer edge of the stopping portion 7112 and extends upward from the outer edge to form a ring shape.

[0053] The sliding layer 712 is laid on the sliding part 7111 and the suspension part 7112. The sliding layer 712 of this embodiment is divided into a plurality of block parts, including a plurality of first sliding layer parts 7121 laid on the sliding part 7111 and a plurality of second sliding layer parts 7122 laid on the suspension part 7112, wherein the number of the first sliding layer parts 7121 and the second sliding layer parts 7122 is the same (8 each) and corresponds one to one.

[0054] The first sliding layer portion 7121 is in a curved fan shape, and each first sliding layer portion 7121 is bent toward the same side along the circumferential direction. The shapes of the two side edges of adjacent first sliding layer portions 7121 match, so that the gaps between each first sliding layer portion 7121 are in the shape of multiple evenly arranged spiral lines.

[0055] The second sliding layer portion 7122 is fan-shaped, and its inner edge is located at the junction of the sliding portion 7111 and the stop portion 7112, corresponding to the outer edge of the first sliding layer portion 7121 with a certain gap between the two; the outer edge of the second sliding layer portion 7122 extends to the stop portion 7113 and contacts with the stop portion 7113.

[0056] The first sliding layer portion 7121 and the second sliding layer portion 7122 are both made of composite fiber material, and in this embodiment, they are made of the fleece layer of nylon Velcro.

[0057] There are eight baffles 713, which are evenly distributed along the circumference and arranged on the outer part of the card-stopping portion 7112. The eight baffles 713 of this embodiment are respectively located between the gaps of two adjacent second sliding layer portions 7122, and the edge portions of both sides of each second sliding layer portion 7122 are also provided with notches corresponding to the baffles 713, so as to facilitate the exposure of the baffles 713. Each baffle 713 is a tendon block, that is, made of rubber or plastic material with a certain elasticity, which can block the mahjong tiles 200 for shuffling and reduce collision noise.

[0058] like Figure 4-5 As shown, the shuffle plate mounting unit includes a bearing 721 and a fixing cap 722.

[0059] The bearing 721 is sleeved in the middle of the mounting seat 108, and its inner ring is adapted and interference fit with the outer surface of the mounting seat 108, and the outer ring is adapted and interference fit with the inner surface of the bearing seat portion 7114. Thus, the shuffle plate 71 is rotatably mounted on the mounting seat 108 through the bearing 721.

[0060] The fixing cap 722 is roughly in the shape of a hollow cone, located above the shuffle plate 71, and is installed on the mounting seat 108 by being threadedly connected with the second external threaded portion 82. The lower surface of the fixing cap 722 abuts against the upper surface of the inner ring of the bearing 721, thereby pressing the bearing 721 into the bearing seat portion 722 and preventing it from loosening. In addition, in this embodiment, the pressing rotation direction of the fixing cap 722 (i.e., the downward rotation direction) is the same as the rotation direction of the shuffle plate 71. Therefore, even if the shuffle plate 71 contacts the fixing cap 722 when rotating and generates a certain driving force, the force can also make the fixing cap 722 produce a downward pressing rotation movement trend, so that the fixing cap 722 can be kept in a pressed state during use to avoid loosening.

[0061] Figure 8 yes Figure 4 A magnified view of part A.

[0062] like Figure 8 As shown, the lower end of the adjustment limit sleeve 24 is provided with a circle of extensions 241 extending vertically downward, and the fixing cap 722 is provided with a receiving groove 7221 for receiving the extension 241. Specifically, the outer wall height of the receiving groove 7221 is higher, formed around the outer periphery of the extension 241, and the inner wall height is lower, and the inner surface of the inner wall is the internal thread for threaded connection with the second threaded portion 82.

[0063] Fig. 9It is an exploded structural diagram of the mounting seat, the adjustment limit sleeve, and the fixing cap according to an embodiment of the present invention.

[0064] like Figure 8-9 As shown, in this embodiment, a plurality of engaging convex strips 242 extending longitudinally along the surface are evenly distributed on the outer surface of the adjusting and limiting sleeve 24 , and these engaging convex strips 242 all extend to the extending portion 241 .

[0065] Fig.10 1 is a structural diagram of a fixing cap according to an embodiment of the present invention.

[0066] like Figure 8-10 As shown, a recessed opening 7220 is provided at the upper end of the outer wall of the accommodating groove 7221, and an elastic sheet 7222 is connected to the recessed opening 7220. A convex block is provided on the inner surface of the elastic sheet 7222 (i.e., the surface facing the adjustment limit sleeve 24), and a plurality of engaging grooves 7223 extending substantially in the longitudinal direction are provided on the convex block. The size of the engaging grooves 7223 and the spacing between adjacent engaging grooves 7223 are matched with the size and spacing of the engaging convex strips 242, so that the engaging grooves 7223 can be engaged with the engaging convex strips 242. Since the fixing cap 722 is made of materials such as plastic, the elastic sheet 7222 itself has a certain elasticity and can apply a certain pressure to the engaging grooves 7223, so that the engaging grooves 7223 and the engaging convex strips 242 remain engaged when not subjected to external force, that is, the two are elastically engaged to form an elastic engaging structure. Therefore, when no external force is applied, the relative rotation between the fixing cap 722 and the adjusting limit sleeve 24 in the circumferential direction is limited by the engagement between the two, that is, the fixing cap 722 and the adjusting limit sleeve 24 cannot rotate relative to each other.

[0067] When the bearing 721 and the shuffling plate 71 are installed on the mounting base 108, when the operator (i.e. the technician who installs or repairs the mahjong machine 100) needs to further install the fixing cap 722 and the adjustment limit sleeve 24, the fixing cap 722 can be screwed onto the second external threaded portion 82 and tightened to press the inner ring of the bearing 721; then, the adjustment limit sleeve 24 can be screwed onto the first external threaded portion 81, and the adjustment limit sleeve 24 can be rotated and stopped at a suitable height position according to the required position when the operating plate 21 is lowered.

[0068] During the above-mentioned installation process or the process of adjusting the height position of the adjusting limit sleeve 24, when the operator rotates the adjusting limit sleeve 24, the force applied by the operator can overcome the elastic force of the elastic sheet 7222, and the engaging groove 7223 and the engaging convex strip 242 can be disengaged, so that the adjusting limit sleeve 24 can rotate relative to the fixing cap 722; when the operator no longer rotates the adjusting limit sleeve 24, the elastic force of the elastic sheet 7222 applies pressure to the engaging groove 7223, so that it returns to the meshing state with the engaging convex strip 242, so that the relative rotation of the fixing cap 722 and the adjusting limit sleeve 24 is restricted again.

[0069] Thus, the operator can conveniently adjust the height position of the adjustment limit sleeve 24 , and at the same time, the adjustment limit sleeve 24 will not rotate relative to the fixing cap 722 during normal use.

[0070] In addition, since the fixing cap 722 always has a tendency to rotate and tighten under the action of the shuffle plate 71, the fixing cap 722 will basically not rotate during actual use, and the adjustment limit sleeve 24 will not rotate accordingly, which can keep the upper end position of the adjustment limit sleeve 24 unchanged. In addition, in this embodiment, the outer surface of the fixing cap 722 is also provided with a plurality of convex strips, which can increase the surface friction and facilitate the operator to twist; at the same time, the engaging convex strip 242 extends to the inclined part of the adjustment limit sleeve 24, which can also increase the surface friction and facilitate twisting.

[0071] The shuffle disk drive unit includes a shuffle motor 731 , a shuffle output gear 732 , a shuffle input ring gear 733 and an auxiliary gear 734 .

[0072] The shuffling motor 731 is fixedly installed below the support plate 1061, and its output shaft passes through the support plate 1061 upward.

[0073] The shuffling output gear 732 is installed on the output end of the shuffling motor 731 and is located below the shuffling disk 71.

[0074] like Figure 4 As shown, a ring gear is provided on the lower surface of the sliding portion 7111, namely, the shuffle input ring gear 733. The shuffle output ring gear 733 is distributed in a ring shape around the bearing seat portion 7114. The shuffle output gear 732 is meshed with the shuffle input ring gear 733, so that the shuffle motor 731 can drive the shuffle disk 71 to rotate through the meshing relationship between the two.

[0075] The number of auxiliary gears 734 in this embodiment is two, each of which is mounted on the table base 106 through a gear mounting seat. The gear mounting seat has a rotating shaft, and the auxiliary gear 734 is rotatably mounted on the rotating shaft and meshes with the shuffle input ring gear 733. The two auxiliary gears 734 and the shuffle output gear 732 are arranged at equal intervals in the circumferential direction (i.e., 120° apart from each other). Through the meshing action of the two auxiliary gears 734 and the shuffle input ring gear 733, the rotation process of the shuffle disk 71 can be made smoother.

[0076] like Figure 5 As shown, a plurality of shuffling plate height adjustment units 74 are evenly distributed circumferentially below the card stopping portion 712 .

[0077] Fig.11 It is a structural diagram of the shuffle plate height adjustment unit of this embodiment.

[0078] like Fig.11 As shown, the shuffle plate height adjustment unit 74 includes a height adjustment seat 741 and a rolling wheel 742.

[0079] The height adjustment seat 741 is fixed on the support plate 1061 and has a pair of seat plates 7411 arranged at intervals. Three height adjustment grooves 7412 with the same width but decreasing depths are arranged on the inner surface of each seat plate 7411 (i.e., the surface on one side facing the other seat plate 7411), and the height adjustment grooves 7412 on the two seat plates 7411 are arranged opposite to each other, and the depths of the height adjustment grooves 7412 at relative positions on the two seat plates 7411 are the same.

[0080] The rolling wheel 742 has a wheel body 7421 and a wheel axle 7422 arranged on the wheel body 7412. The diameter of the wheel axle 7422 is adapted to the width of the height adjustment groove 7412. The distance between the two ends of the wheel axle 7422 matches the distance between the two opposite height adjustment grooves 7412. The wheel body 7412 can be respectively placed in the two opposite height adjustment grooves 7412 so that the wheel body 7412 is located between the two seat plates 7411.

[0081] The wheel body 7421 is in contact with the lower surface of the disk body 711, and can support the card-suspending part 712 during the rotation of the shuffle disk 71. Since the card-suspending part 712 is at a certain distance from the bearing seat part 714, when a large number of mahjong tiles 200 are piled on the card-suspending part 712, it is easy to sink due to the load. The support of the wheel body 7421 can prevent the occurrence of such sinking phenomenon, so that the card-loading mechanism 101 can more easily absorb the mahjong tiles 200 on the card-suspending part 712. In addition, when the wheel shaft 7422 is placed in the height adjustment groove 7412 with different depths, the height of the support formed by the wheel body 7421 on the card-suspending part 712 is also different, and the height of the card-suspending part 712 can be slightly raised or lowered, so the support height can be adjusted according to mahjong tiles 200 of different specifications, further making the absorption action of the card-loading mechanism 101 easier to achieve.

[0082] The mahjong machine 100 of this embodiment can be used by four users at the same time, and accordingly, four card loading mechanisms 101 are provided, which are respectively located at the four corners of the table base 106. Each card loading mechanism 101 can absorb mahjong tiles 200 from the card resting part 7112, stack the tiles, and raise the stacked mahjong tiles 200 to the table for users to use. The specific structure and working principle thereof can adopt the existing technology, and will not be repeated here.

[0083] Example Function and Effect

[0084] According to the operating panel and shuffling integrated system and mahjong machine provided in this embodiment, since the mounting seat 108 is provided with a first threaded portion 81 and a second threaded portion 82, the adjusting limit sleeve 24 is threadedly connected to the first threaded portion, and the fixing cap 722 is threadedly connected to the second threaded portion 82, and an elastic snap-fit ​​structure is provided between the adjusting limit sleeve 24 and the fixing cap 722. When not subjected to external force, the two do not rotate relative to each other, making it difficult for the adjusting limit sleeve 24 to rotate. When subjected to external force, the two can rotate relative to each other so that the position of the adjusting limit sleeve 24 can be adjusted. Therefore, on the one hand, the height position of the adjusting limit sleeve 24 can be maintained during normal use, so that the descending position of the control panel 1021 will not change. On the other hand, the adjusting limit sleeve 24 can be rotated by only twisting the adjusting limit sleeve 24 to overcome the elastic force and disengage the elastic snap-fit ​​structure, thereby realizing the high and low adjustment of the descending position of the control panel 1021. The adjustment process can be realized without removing the control panel 1021, so installation and maintenance are very easy to achieve.

[0085] In the embodiment, since the thread directions of the first threaded portion 81 and the second threaded portion 82 are opposite, the elastic engaging structure will not cause the adjusting limit sleeve 24 and the fixing cap 722 to rotate together, thereby causing the two to loosen together. In addition, since the pressing rotation direction of the fixing cap 722 is the same as the rotation direction of the shuffle plate 71, the force generated by the contact between the shuffle plate 71 and the fixing cap 722 during rotation can keep the fixing cap 722 in a pressed state during use, further preventing it from loosening.

[0086] In the embodiment, since a locking ridge 242 is provided on the extension portion 241 of the adjustment limit sleeve 24, an elastic sheet 7222 is provided on the accommodating groove 7221 that accommodates the extension portion 241, the locking groove 7223 on the elastic sheet 7222 and the locking ridge 242 together constitute an elastic locking structure. Therefore, elastic locking can be achieved without setting up additional elastic components, and manufacturing and assembly are easier to achieve.

[0087] Those skilled in the art should understand that the present invention is not limited to the above-mentioned embodiments. The above-mentioned 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 technical solution may be subject to various changes and improvements, and these changes and improvements shall fall within the scope of protection claimed by the present invention.

[0088] For example, in the embodiment, the engaging convex strip 242 on the extension part 241 of the adjustment limit sleeve 24 and the engaging groove 7223 on the elastic sheet 7222 connected to the receiving groove 7221 together form an elastic engaging structure. As an alternative, the positions of the engaging convex strip 242 and the elastic sheet 7222 can also be exchanged, that is, a recessed opening is provided on the extension part 241 and connected to the elastic sheet 7222, and the engaging convex strip 242 is provided on the inner surface of the outer wall of the receiving groove 7221, as long as the engaging groove 7223 on the elastic sheet 7222 and the engaging convex strip 242 can be arranged relative to each other and can mesh with each other.

[0089] As a further alternative, the elastic snap-fit ​​structure may also be in other forms. For example, a snap-fitting groove is provided on one of the extension portion 241 and the receiving groove 7221, and a snap-fitting block with a spring is fixedly provided on the other, which can also play the role of snapping with each other when not subject to external force, and not snapping when subject to external force, and allowing the adjustment limit sleeve 24 and the fixing cap 722 to rotate relative to each other.

[0090] In addition, in the embodiment, the thread directions of the first threaded portion 81 and the second threaded portion 82 are opposite, and the two are not easy to be loosened together. However, when the pressing rotation direction of the fixing cap 722 is the same as the rotation direction of the shuffle plate 71, the thread directions of the first threaded portion 81 and the second threaded portion 82 can also be set to be the same. In this case, since the fixing cap 722 is pressed on the bearing 721 and is not easy to rotate, the elastic engagement can also make the adjustment limit sleeve 24 not easy to rotate.
