As shown in fig. 7, the positioning groove 5-1 may be various, such as: a positioning groove concavely formed around the circumferential direction (which may be a complete circumference or a part of the circumference) of the drawbar 5 as shown in fig. 7-a; or as shown in fig. 7-B, a point-shaped positioning groove is formed on the wall surface of the pull rod 5. The tie rod 5 may use a rigid strip of material such as cylindrical metal strip, plastic strip, etc. of fig. 7-A, B or C, and may use a rigid strip of metal strip, plastic strip, etc. having a square or rectangular cross section as shown in fig. 7-D.

Since the flute is slid, it is difficult to pull the piston 4 to a position where a certain tone level is desired, and it is difficult for a user (especially a beginner) to play the musical instrument because the tone is changed without pulling to the corresponding position. According to the flute, the structure of the pull rod 5 is changed, the elastic device 3 is arranged at the tail part of the flute body 2, and the pull rod 5 can be positioned (actually, the piston 4 is positioned) in different positioning grooves 5-1 by the elastic device 3 through pushing and pulling the pull rod 5; the user can find a certain tone more simply and accurately.

The above-mentioned tone scale refers to each tone in the musical tone system, and can be divided into a basic tone scale and a variable tone scale.

In the musical tone system, the high and low signs of the recorded sounds are called notes. Each note represents a scale level. In the sound column, there are seven classes with independent names called basic classes,

the number of lines is l, II, III, IV, V, vl, VII.

In this embodiment, the basic sound levels are all the basic sound levels, the basic sound levels are continuously recycled in the low, middle and high ranges, and the sound level corresponding to the low-pitch range is

The scale of the middle pitch range is 1, 2, 3, 4, 5, 6 and 7; the corresponding high pitch range has a sound level of

As shown in FIGS. 2 and 3, as a specific embodiment, the elastic means 3 may directly use a positioning bead (shown in FIG. 4A) specifically comprising a housing 3-1, a spring 3-2 and a ball 3-3; the ball 3-3 is arranged in the shell 3-1 after compressing the spring 3-2, and the ball 3-3 is abutted against the pull rod 5; the ball 3-3 is connected with the pull rod 5 in a sliding way, and the ball 3-3 is used for being clamped in different positioning grooves 5-1 in the pushing and pulling processes of the pull rod 5; the relative position of the elastic device 3 and the flute body 2 in the pushing and pulling directions of the pull rod 5 is kept unchanged in the pushing and pulling processes of the pull rod 5. When the design mode is used, when the pull rod 5 is pushed or pulled, the user can feel the pause feeling when the elastic device 3 (particularly the ball 3-3) is clamped in the positioning groove 5-1.

Besides the above structure, the elastic device 3 may also be a pogo pin (as shown in fig. 4B, the reference numeral 3 is a pogo pin), a spring (as shown in fig. 4C, the reference numeral 3 is a spring), or other elements or devices with elastic function.

In the process of pushing and pulling the pull rod 5, there are many ways to keep the relative position of the elastic device 3 and the flute body 2 in the pushing and pulling directions of the pull rod 5 unchanged, so as to fix the elastic device 3 and the flute body 2 at the tail part of the flute body 2, so that when the pull rod 5 is pushed and pulled, the elastic device 3 only slides relative to the pull rod 5, and the position between the elastic device 3 and the flute body 2 is unchanged.

There are many ways to fix the elastic means 3 on the tail of the flute body 2. Fig. 4 shows a way, in particular, the elastic device 3 is directly fixed on the inner wall of the tail part of the flute body 2 (the fixing way can be welding, gluing, etc.), and the ball 3-3 is abutted against the pull rod 5. The state in fig. 4A is that the ball 3-3 is snapped into one of the positioning grooves 5-1.

Fig. 5 shows another way, as shown in fig. 2 and 5, said elastic means 3 further comprise a fixing sleeve 3-4 for fixing the casing 3-1; the fixed sleeve 3-4 is provided with a through hole 3-41 for the pull rod 5 to pass through; the fixed sleeve 3-4 is detachably connected with the tail part of the flute body 2, the fixed sleeve 3-4 can be directly sleeved at the tail part of the flute body 2, the fixed sleeve 3-4 can be made into a plug shape and inserted into the tail part of the flute body 2, and the fixed sleeve 3-4 can be in threaded connection with the tail part of the flute body 2; the shell 3-1 is fixed in the fixed sleeve 3-4.

In addition to the adhesive means, this patent also provides a means of securing, as shown in fig. 6, the housing 3-1 within the pouch 3-41 using a securing cap 3-42. The side of the fixed cover 3-42 close to the shell 3-1 is provided with a buckle 3-421 for providing vertical (vertical refers to the pushing and pulling directions of the pull rod 5) fixation for the shell 3-1, and in order to enable the buckle 3-421 to better fix the shell 3-1, the side of the buckle 3-421 contacting with the shell 3-1 is provided with a groove part 3-423 matched with the shape of the shell 3-1. The edge of the fixing cover 3-42 is formed with a stop button 3-422 extending in the direction of the housing 3-1, and the stop button 3-422 is used for providing a stop for the housing 3-1 in the transverse direction (referring to the extension and contraction direction of the spring 3-2). The fixing mode is convenient to install.

The sliding flute can simply and accurately find a certain sound level in actual use. If the positioning groove 5-1 is of the type shown in fig. 7-B, the elastic means 3 is not easily caught in the positioning groove 5-1 since the pull rod 5 is rotated, and therefore, it is necessary to provide a structure for easily catching the elastic means 3 with the positioning groove 5-1. Specifically, as shown in fig. 7-C, a slide rail 5-2 is arranged on the pull rod 5 along the extending direction of the pull rod 5, and the positioning groove 5-1 is arranged on the slide rail 5-2; the elastic device 3 moves along the slide rail 5-2 in the pushing and pulling processes of the pull rod 5 and is clamped in the positioning groove 5-1 at the positioning groove 5-1. When the elastic device is used in the mode, the elastic device 3 can slide along the slide rail 5-2 and can be clamped in the positioning groove 5-1 when reaching the positioning groove 5-1. The slide rail 5-2 can be directly formed on the wall surface of the pull rod 5, but if the pull rod 5 is made of metal material, the cost for forming the slide rail 5-2 is higher, therefore, an implementable scheme is provided as shown in fig. 7-E, a sliding sleeve 6 is sleeved on the pull rod 5, and the positioning groove 5-1 and the slide rail 5-2 are directly formed on the sliding sleeve 6, so that the problems can be solved. The sliding sleeve 6 can be made of hard materials such as plastics. The pull rod 5 and the sliding sleeve 6 can be fixed by gluing.

In order to make it more convenient for the user to find a certain sound level accurately, a specific possible implementation is provided below, as shown in fig. 8, a sound name 2-1 for indicating the sound level is provided on the flute body 2, and the sound name 2-1 identifies the sound emitted by the mouthpiece 1 when the piston 4 is at the position corresponding to the sound name 2-1. In fig. 8, a specific notation of the note name 2-1 is provided, the range of the range from the top to the tail of the flute body 2 is

In addition, since the flute can be A, B, C, D, E, F, G tone,the pitch name 2-1 is not limited to the manner shown in fig. 8, and other pitch range ranges may be made.

The flute body 2 is made of transparent non-metallic materials, and the corresponding position of the piston 4 and the pitch name 2-1 can be clearly seen when playing. Although the flute body 2 made of non-metal material (such as plastic material) can reduce the production cost, the non-metal material has poor texture, the sound coming out is very thin, the penetration force is poor, and the tone quality is not thick, therefore, the flute body 2 made of metal material can be used, for example: aluminum alloy and the like, which are made of thin aluminum alloy materials, have strong vibration, stable, thick and penetrating sound, crisp and mellow tone, transparency and higher sound volume. If the flute body 2 is made of metal, the corresponding position of the piston 4 and the note name 2-1 cannot be visually seen during playing due to the fact that the metal is opaque, and in order to solve the problem, a specific implementation scheme capable of solving the problem is provided, as shown in fig. 8 and 9, the pull rod 5 is integrally U-shaped, one of two arms of the U-shaped is pushed and pulled in the flute body 2, the other arm of the U-shaped is arranged outside the flute body 2, an identification part 5-3 is arranged at the end part of the arm extending out of the flute body 2, the identification part 5-3 and the piston 4 are located at the same horizontal height, and the identification part 5-3 points to the piston 4. The design of this structure, no matter what material the flute body 2 is, will not influence the position of the piston 4 clearly indicated.

As shown in fig. 8, the number of the pitch names 2-1 is the same as the number of the positioning slots 5-1, (the upper and lower parts in this section are described by taking fig. 8 as an example), the user pulls the pull rod 5 downward, the elastic device 3 first touches the first positioning slot 5-1 at the lowest position on the slide rail 5-2, and at this time, the piston 4 is located in the pitch name 2-1 (in the figure:

) The corresponding position, the identification part 5-3 points to the phonetic name 2-1 (in the figure:

) At the moment, the playing flute can send out

The representative sounds.
