Description

Technical Field

[0001] The utility model relates to the technical field of stringed instrument accessories, in particular to a guitar right hand nail trimming tool. Background Art

[0002] String instruments such as guitars are usually plucked with fingernails. Therefore, the shape of the fingernails has a great influence on the timbre and quality of the sound. To ensure the performance effect and quality, the fingernails need to be trimmed and polished before playing. The conventional trimming method is to trim the fingernails with nail clippers and then polish the fingernails with a polishing strip to achieve a nail shape that is suitable for the player's plucking posture.

[0003] Different players have different picking postures and nail shapes. The trimming and polishing of nails are key. The shape of nails should be trimmed according to the player's picking posture, so that the shape of nails fits the player's picking posture and habits, thereby ensuring the performance effect. For experienced players, it is not difficult to trim nails through conventional trimming methods to achieve the purpose of fitting their own picking posture and picking habits, but for beginners, this is more difficult.

[0004] Beginners generally have a low level of mastery of string instruments. On the premise of maintaining their own picking posture and habits, they can also trim the shape of their nails, but the trimming effect is poor and it is difficult to achieve an ideal nail shape. Beginners need to trim repeatedly and play the strings after each trimming until the string sound is satisfactory. Only then will the nail shape be suitable for their own picking posture. This process is very inconvenient.

[0005] The above conventional trimming and polishing process is relatively complicated and not friendly to beginners. For this reason, the authorization announcement number CN215933174U discloses a plucked instrument nail trimming device, in which multiple steel wires are arranged on the support, and the steel wires are equivalent to the strings. The surface of the steel wires is sandblasted to form a rough surface, which is used as a nail trimming tool. When in use, the nails are trimmed by plucking the steel wires, and the trimming fit is just adapted to the plucking habits, directly meeting the trimming requirements.

[0006] However, directly simulating the strings during the trimming process is different from the plucking posture of directly playing a string instrument, so there are also differences in the trimming of the nails. Moreover, the above nail trimming devices can only be used before and after playing a musical instrument, and cannot be used during the performance. The nails need to be roughly trimmed and finely trimmed, and the grain size of the steel wire sandblasting on the above nail trimming devices is consistent, which requires the use of multiple nail trimming devices with different grain sizes, which increases the cost of use, and the switching is more cumbersome. Summary of the invention

[0007] In order to solve the problem that conventional trimming tools are difficult to conveniently trim nails to match the string-stirring posture after one trimming, the utility model provides a guitar right hand nail trimming tool, which is adsorbed on the guitar panel and arranged on the path of the finger string-stirring action, so that the nails can be trimmed immediately while the strings are being plucked, thereby realizing convenient and accurate nail shape trimming.

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0009] The utility model relates to a guitar right hand nail trimming tool, which is arranged on a guitar panel and comprises a base, a suction cup, a sliding plate, a movable supporting shaft, a spacing adjustment mechanism, a fixed supporting shaft and a sandpaper ring.

[0010] The bottom surface of the base is provided with a suction cup to be adsorbed and connected with the guitar panel, so as to facilitate the disassembly and assembly of the base from the guitar panel. The sliding plate is slidably arranged in front of the base, and the dynamic support shaft is plugged and unplugged on the sliding plate. The sliding plate is convenient to move with the dynamic support shaft, and both ends of the dynamic support shaft are passed through the base. A spacing adjustment mechanism for driving the sliding plate to slide is arranged in the middle of the base, and the spacing adjustment mechanism is connected to the sliding plate, so as to facilitate the sliding plate to slide along the base.

[0011] The fixed support shaft is plugged in and out at the rear of the base, and the position of the fixed support shaft is fixed. The dynamic support shaft and the fixed support shaft are arranged in parallel with each other at a front-back interval. The sandpaper ring is wrapped between the fixed support shaft and the dynamic support shaft. The sandpaper ring is a flat ring structure formed by bonding at least two sandpapers with different mesh sizes, and can provide rough trimming and fine trimming functions.

[0012] Furthermore, the base is a plate body with a "["-shaped cross-section, and the suction cups are arranged at the four corners of the bottom surface of the base, which improves the reliability of the base fixation. The suction cups are threadedly connected to the base to facilitate the disassembly and assembly of the suction cups. Slide grooves are provided on the inner walls on both sides of the base, and one end of the slide groove extends to the end face of the base to provide guidance for the movement of the sliding plate.

[0013] Furthermore, the sliding plate is also a plate body with a "["-shaped cross-section. The cross-section of the sliding plate is smaller than the cross-section of the base. The outer wall of the sliding plate fits with the inner wall of the base, and the two match each other, thereby improving the sliding stability of the sliding plate. The two ends of the sliding plate extend horizontally outward to form a slider, and the slider extends into the slide groove and slides along the slide groove, thereby facilitating the sliding cooperation between the sliding plate and the base.

[0014] Furthermore, long strip-shaped slideways are provided on both side walls of the base, which facilitates the dynamic support shaft to pass through the base, and the slideways and slide grooves are arranged in parallel with each other at intervals.

[0015] The dynamic support shaft is passed through between the two sides of the sliding plate, and the dynamic support shaft includes a long axis body, a knob and a threaded section. The threaded section is coaxially arranged at one end of the long axis body, and the threaded section extends into the slideway on one side and slides along the slideway. The other end of the long axis body extends outward through the slideway on the other side and is connected to the knob. The knob facilitates the rotation of the entire dynamic support shaft, and the threaded section prevents the dynamic support shaft from axial movement.

[0016] Furthermore, the fixed support shaft and the dynamic support shaft have the same structure and function, except that one is fixed and the other is movable. The fixed support shaft is inserted between the two sides of the base, and the threaded section of the fixed support shaft is threadedly connected to the base. The knobs of the fixed support shaft and the dynamic support shaft are both located outside the base, which facilitates the rotation and insertion and removal operations of the fixed support shaft and the dynamic support shaft.

[0017] Furthermore, the fixed support shaft and the dynamic support shaft are located at the same height plane, the spacing adjustment mechanism is arranged between the fixed support shaft and the dynamic support shaft, the fixed support shaft cooperates with the dynamic support shaft to tighten the sandpaper ring, and the spacing adjustment mechanism is arranged under the sandpaper ring to avoid interference between the spacing adjustment mechanism and the sandpaper ring when it moves.

[0018] Furthermore, the spacing adjustment mechanism includes a manual screw, a sliding seat, a connecting rod and a limit block. The manual screw is rotatably arranged on the base, and the manual screw, the fixed support shaft and the movable support shaft are arranged in parallel with each other. One end of the manual screw extends out of the base and is provided with a dial wheel to facilitate the rotation of the manual screw. The sliding seat is meshed on the manual screw, and the connecting rod is hinged between the sliding seat and the sliding plate. The base is also provided with the limit block for limiting the displacement of the sliding seat, which is convenient for limiting the moving position of the sliding seat.

[0019] Through the above technical solution, the beneficial effects of the utility model are:

[0020] The utility model has a reasonable structural design. The trimming tool can be firmly attached to the guitar panel through multiple suction cups. The trimming tool has a sandpaper ring that is stretched and tightened. When the performer plucks the strings, the nails move back and forth between the strings and the sandpaper ring. Since the performer must be in the plucked posture he is accustomed to when plucking the strings, the nails can be polished and trimmed when they contact the sandpaper ring. The nails can be corrected while plucking the strings, and the nails can be trimmed into the required shape very conveniently. In short, the fit of the trimmed shape can be matched with the habit of plucking the strings, and the trimming requirements can be directly met without the tedious operations of conventional multiple trimming and multiple string plucking inspections.

[0021] The fixed support shaft of the utility model is fixed, and the sliding plate can move with the moving support shaft on the base. The movement of the sliding plate is realized by the spacing adjustment mechanism, which can conveniently adjust the spacing between the fixed support shaft and the moving support shaft. The fixed support shaft and the moving support shaft are plugged in and out, which facilitates the installation and tightening of the sandpaper ring. The fixed support shaft and the moving support shaft provide support for the sandpaper ring to prevent the sandpaper ring from being soft and deformed, which is convenient for the performer to trim the nails. The sandpaper ring can be made of two or more sandpapers of different meshes bonded by double-sided tape, which can provide rough and fine trimming functions for the nails.

DETAILED DESCRIPTION

[0031] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings:

[0032] like Figure 1 to Figure 8 As shown, a guitar right hand nail trimming tool is arranged on the guitar panel 1. The specific arrangement position is on the path of the finger plucking action, that is, the nail needs to reciprocate between the strings and the nail trimming tool during playing, so that the nail can be trimmed while plucking the strings. When the sound of the plucking is satisfactory, the nail is trimmed to a suitable shape.

[0033] In this embodiment, the base 2, the suction cup 3, the sliding plate 4, the dynamic support shaft 5, the spacing adjustment mechanism 6 and the fixed support shaft 7 and the sandpaper ring 8 are included. Figure 1 and Figure 2 The base 2 is a plate body with a cross section in the shape of a "[". To facilitate the installation of the base 2 and the guitar panel 1, a suction cup 3 is provided on the bottom surface of the base 2.

[0034] Specifically, suction cups 3 are arranged at the four corners of the bottom surface of the base 2, and a cylinder is disposed above the suction cups 3. The cylinder is processed with threads, so the suction cups 3 can be threadedly connected with the base 2 to realize the disassembly and assembly of the suction cups 3. The base 2 is adsorbed and connected to the guitar panel 1 through the suction cups 3 to ensure that the base 2 is fixed on the guitar panel 1. Through the adsorption connection method, the base 2 can be installed at any position of the guitar panel 1 to match the string picking positions of different players.

[0035] A sliding plate 4 is slidably arranged in front of the base 2, and the sliding plate 4 can slide relative to the base 2. The contour shape of the sliding plate 4 is consistent with the contour shape of the base 2, that is, the sliding plate 4 is also a plate body with a cross-section in the shape of "[". The cross-section of the sliding plate 4 is smaller than the cross-section of the base 2, and the outer wall of the sliding plate 4 fits with the inner wall of the base 2 to ensure that the sliding plate 4 will not move left and right when sliding. Figure 4 and Figure 5 shown.

[0036] In order to guide the sliding plate 4 when sliding, the inner walls of both sides of the base 2 are provided with slide grooves 9, which have a certain length and one end of which is open, that is, one end of the slide groove 9 extends to the end surface of the base 2, so as to ensure that the sliding plate 4 can be smoothly installed in the slide groove 9 through the opening. At the same time, both ends of the sliding plate 4 extend outward horizontally to form sliders 10, which extend into the slide groove 9 and slide along the slide groove 9, thereby providing guidance for the sliding of the sliding plate 4.

[0037] The movable support shaft 5 is inserted and pulled out of the sliding plate 4, and the two ends of the movable support shaft 5 are inserted into the base 2. On the basis that the sliding plate 4 can slide, the movable support shaft 5 will move along with the sliding plate 4. In order to allow the sliding of the movable support shaft 5, the two side walls of the base 2 are provided with long slideways 11, and the slideways 11 and the slide grooves 9 are arranged in parallel with each other at intervals, and the slideways 11 can ensure that the movable support shaft 5 moves on the base 2.

[0038] The plug-in and pull-out relationship between the sliding plate 4 and the dynamic support shaft 5 is as follows: the dynamic support shaft 5 is inserted between the two sides of the sliding plate 4, so holes are opened on both sides of the sliding plate 4, namely, the light hole 12 and the threaded hole 13. The dynamic support shaft 5 includes a long shaft body 51, a knob 52 and a threaded section 53. The threaded section 53 is coaxially arranged at one end of the long shaft body 51, that is, one end of the long shaft body 51 is processed with a thread to form the threaded section 53. The threaded section 53 extends into the slideway 11 on one side and slides along the slideway 11. The other end of the long shaft body 51 extends outward through the slideway 11 on the other side and is connected to the knob 52. Turning the knob 52 can control the rotation of the dynamic support shaft 5.

[0039] When the dynamic support shaft 5 is installed with the sliding plate 4: the threaded section 53 passes through the light holes 12 and the threaded holes 13 on both sides of the sliding plate 4 in sequence, so that the long axis body 51 is located in the openings on both sides of the sliding plate 4, and the dynamic support shaft 5 can be rotated at will. The knob 52 on the dynamic support shaft 5 is located outside the base 2 and fits the outer wall of the base 2. At this time, the dynamic support shaft 5 can no longer move axially. Only by rotating the dynamic support shaft 5 can it move axially, which can prevent the dynamic support shaft 5 from easily detaching from the sliding plate 4.

[0040] A fixed support shaft 7 is plugged in and out of the rear of the base 2, and the dynamic support shaft 5 and the fixed support shaft 7 are arranged in parallel with each other at intervals in front and behind, and the fixed support shaft 7 and the dynamic support shaft 5 have the same structure. Here, the fixed support shaft 7 is inserted between the two sides of the base 2. When the fixed support shaft 7 and the base 2 are installed: a light hole 12 and a threaded hole 13 are also opened on both sides of the base 2, and the threaded section 53 of the fixed support shaft 7 is threadedly connected with the base 2, and the knob 52 of the fixed support shaft 7 is also located outside the base 2, so that the axial movement of the fixed support shaft 7 can be limited to prevent it from easily detaching from the base 2.

[0041] The sandpaper ring 8 is used for trimming and polishing nails. The sandpaper ring 8 is wrapped between the fixed support shaft 7 and the dynamic support shaft 5. To ensure the flatness of the sandpaper ring 8, the fixed support shaft 7 and the dynamic support shaft 5 are located at the same height. The sandpaper ring 8 is a flat ring structure formed by bonding at least two sandpapers with different mesh sizes. Double-sided tape can be used for bonding. The shape of the sandpaper ring 8 is similar to a conveyor flat belt, such as Figure 3 shown.

[0042] The sandpaper ring 8 can be used for rough and fine trimming of nails by using sandpaper of different mesh sizes. When trimming nails, the sandpaper ring 8 at the position of the fixed support shaft 7 and the dynamic support shaft 5 is used for grinding, because the sandpaper ring 8 at this position is supported by the fixed support shaft 7 and the dynamic support shaft 5 to avoid compression deformation and failure to achieve the grinding effect.

[0043] The above plug-in connection between the fixed support shaft 7 and the dynamic support shaft 5 is for the convenience of installing the sandpaper ring 8. At the same time, the fixed support shaft 7 cooperates with the dynamic support shaft 5 to tighten the sandpaper ring 8, that is, the fixed support shaft 7 and the dynamic support shaft 5 are first approached to each other, and then move away from each other after the sandpaper ring 8 is installed, to ensure that the sandpaper ring 8 is smoothly opened.

[0044] The approach and distance between the fixed support shaft 7 and the dynamic support shaft 5 are realized by the spacing adjustment mechanism 6, that is, the middle part of the base 2 is provided with a spacing adjustment mechanism 6 for driving the sliding plate 4 to slide, the spacing adjustment mechanism 6 is located between the fixed support shaft 7 and the dynamic support shaft 5, and the spacing adjustment mechanism 6 is arranged below the sandpaper ring 8. The spacing adjustment mechanism 6 is connected to the sliding plate 4, and the sliding plate 4 can be driven to slide through the spacing adjustment mechanism 6, thereby changing the spacing between the fixed support shaft 7 and the dynamic support shaft 5.

[0045] The spacing adjustment mechanism 6 includes a manual screw 61, a sliding seat 62, a connecting rod 63 and a limit block 64. The manual screw 61 is rotatably arranged on the base 2, and the manual screw 61 is processed with thread teeth. The manual screw 61 is also processed with a retaining ring groove 14, and a retaining ring is arranged in the retaining ring groove 14. The retaining ring is not shown in the figure, and the retaining ring is against the inner wall of the base 2. The retaining ring can prevent the manual screw 61 from axial movement, such as Figure 6 The manual screw 61, the fixed support shaft 7 and the movable support shaft 5 are arranged in parallel with each other, one end of the manual screw 61 extends out of the base 2 and is provided with a dial wheel 15, which can be driven to rotate by rotating the dial wheel 15, and the dial wheel 15 is attached to the outer wall of the base 2.

[0046] The manual screw 61 is meshed with a sliding seat 62. The rotation of the manual screw 61 can drive the sliding seat 62 to move linearly. The moving direction of the sliding seat 62 is perpendicular to the moving direction of the sliding plate 4. A connecting rod 63 is hinged between the sliding seat 62 and the sliding plate 4. When the sliding seat 62 moves, it can push and pull the sliding plate 4 to move under the drive of the connecting rod 63. A limit block 64 for limiting the displacement of the sliding seat 62 is also provided on the base 2.

[0047] The installation and use process of the utility model is as follows: first, prepare the sandpaper ring 8 according to the demand, and then rotate the dial wheel 15 to rotate the manual screw 61, and pull the sliding plate 4 inward under the transmission of the sliding seat 62 and the connecting rod 63, so that the fixed support shaft 7 and the movable support shaft 5 are close to each other. Figure 7 As shown in A.

[0048] Then remove the fixed support shaft 7 and the dynamic support shaft 5. Here, you only need to rotate the fixed support shaft 7 and the dynamic support shaft 5 to disengage the threaded section 53 from the threaded hole 13. At this time, the fixed support shaft 7 can slide axially on the base 2, and the dynamic support shaft 5 can slide axially on the sliding plate 4. The fixed support shaft 7 and the dynamic support shaft 5 are manually pulled outward to make their threaded sections 53 away from the threaded hole 13. Figure 7 As shown in B. Then place the sandpaper ring 8 prepared in advance in the base 2, as shown in Figure 7As shown in Figure C, the fixed support shaft 7 and the dynamic support shaft 5 are manually pushed inward so that the threaded section 53 is close to the threaded hole 13, and the fixed support shaft 7 and the dynamic support shaft 5 are rotated so that they are respectively connected to the base 2 and the sliding plate 4. At this time, the fixed support shaft 7 and the dynamic support shaft 5 are inserted at both ends of the sandpaper ring 8, as shown in Figure C. Figure 7 The thumbwheel 15 is rotated in the opposite direction to move the sliding plate 4 outward, so that the fixed support shaft 7 and the movable support shaft 5 are separated from each other, and the sandpaper ring 8 can be gradually stretched out until it is tight, and the entire dressing tool is installed. Figure 7 By comparing the circled portion in Figure A with the circled portion in Figure E, it can be clearly seen that the dynamic support shaft 5 has slipped.

[0049] When the nail shape needs to be trimmed, it is fixed to a suitable position of the guitar panel 1 by the suction cup 3, such as Figure 8 When the player plucks the strings, the nails move back and forth between the strings and the trimming tool, and the sandpaper ring 8 at the fixed support shaft 7 and the movable support shaft 5 is used to trim and polish the shape of the nails, so that the player can trim the nails while plucking the strings, and the nails can be trimmed conveniently. Therefore, the nail shape that needs to be trimmed can be directly obtained according to the player's usual plucking posture, and the player can be trimmed once to match the plucking posture of the player.

[0050] It should be noted that: 1. You can first use the coarse sandpaper on the sandpaper ring 8 to roughly trim the nails, and then reduce the distance between the fixed support shaft 7 and the dynamic support shaft 5. At this time, adjust the position of the sandpaper ring 8 so that the fine sandpaper on the sandpaper ring 8 is located at the position of the fixed support shaft 7 or the dynamic support shaft 5, and then adjust the dynamic support shaft 5 to cooperate with the fixed support shaft 7 to support the sandpaper ring 8. You can use fine sandpaper to finely trim the nails, so that the nails can be easily polished into a shape suitable for your own string-playing habits. 2. This nail trimming tool can not only trim the nails during the performance, but also be removed from the guitar panel 1 and used alone.

[0051] The embodiments described above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, any equivalent changes or modifications made based on the structures, features and principles described in the patent scope of the present invention should be included in the patent application scope of the present invention.
