Abstract
The present invention relates to a kind of tools for learning instrument expansion finger spacing, belong to orthopedic tool technical field.A kind of experienced qin expansion refers to device, including fingerstall, is placed in the telescopic rods of the fingerstall two sides, it is characterised in that: the fingerstall quantity at least two, and pass through telescopic rod change position and fixation between each other.The beneficial effects of the present invention are: simple structure, expansion refer to that spacing can be changed with several degree, is easy to use, various informative, occupied little space.Between adjacent fingerstall by can self-locking telescoping rod be connected to a fixed, achieve the purpose that take exercise each Fingers away from opening dynamics；Due to hinged with telescopic rod at the tie point of each fingerstall, fingerstall can be rotated around flexible rod axis, therefore can realize the function of space displacement, achieve the purpose that angle when finger is opened in adjustment.Guarantee practitioner during idle time can opponent's fingering row consciously or not consciously expansion span practice.
Description
Technical field
The present invention relates to a kind of expansions to refer to device, more particularly to a kind of work of practice thrum kind musical instrument expansion finger spacing
Tool.
Background technique
It playing the piano or hand should keep certain state when guitar, any one basic action exercise is bad,
It will lead to a series of problem.As finger is bad in place, not enough uprightly presses string.It is established for a piece of music very careful before fingering
Than much more significant careful, that fingering thinks the influence played than generally practising qin person.
Expansion refers to, is called the stretching, extension of finger, refers to finger is laterally flared, touching two fingers and finger between them
Several summations is less than the fingering of the interval number for two sounds to be touched.Beginner, especially adult, if it is correct to think little of culture
Hand-type, arrived certain degree, can not catch up with learn qin speed paces, seriously affect beginner because of wrong hand-type and play
Quality expands the tool of finger therefore, it is necessary to which providing a kind of expansion that flexibility ratio is relatively high refers to device when as learning instrument.
Summary of the invention
It is an object of the present invention to provide a kind of white silk qin expansions of achievable multiple degrees of freedom displacement to refer to device, mechanically
Expand span, make finger generate muscle memory, it can be achieved that spatial dimension intramedullary expansion finger purpose, to cultivate just organ learner
Correct hand-type.
In order to achieve the above object, The technical solution adopted by the invention is as follows: a kind of white silk of achievable multiple degrees of freedom displacement
Qin expansion refers to device, includes fingerstall, fixed telescopic rod, the telescopic rod is by stretching the lateral position for realizing that fingerstall drives finger
It moves, and is coupled on telescopic rod with spring button and several card slots, play fixed self-locking.
Above-mentioned white silk qin expansion refers to device, wherein the telescopic rod joint number is 2-3, it is isometric.
Above-mentioned white silk qin expansion refers to device, wherein plane where the telescopic rod is vertical with the axis of fingerstall.
Above-mentioned white silk qin expansion refers to device, wherein the fingerstall number is 2-4.
Above-mentioned white silk qin expansion refers to device, wherein the fingerstall is made of plastics or metal.
It is various informative the beneficial effects of the present invention are: structure is simple, between adjacent fingerstall by can self-locking telescoping rod be connected
Connect fixation, achieve the purpose that take exercise each Fingers away from opening dynamics；Due at the tie point of each fingerstall and telescopic rod
Hingedly, fingerstall can be around Plane Rotation where telescopic rod, therefore can realize the function of space displacement, when reaching adjustment to finger opening
The purpose of angle.
Detailed description of the invention
Fig. 1 is the whole assembling schematic diagram of the present invention；
Fig. 2 is overall structure of the present invention；
Fig. 3 is another structural schematic diagram of the present invention;
Fig. 4 is the schematic diagram of Telescopic rod structure of the present invention.
Wherein: 1. fingerstall；2. telescopic rod；3. telescopic rod-fingerstall connects boss；4. card slot；5. spring button.
Specific embodiment
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the overall structure diagram that present invention expansion refers to device.Include telescopic rod (2), the telescopic rod (2) and refers to
It is vertical to cover (1) axis, provides fixed and self-locking for single unit system.
Fig. 2 is that present invention expansion refers to structural schematic diagram after device fingerstall indexing.The telescopic rod (2) due to end and refers at this time
It covers (1) hingedly, therefore can realize the indexing function of fingerstall.
Fig. 3 is that present invention expansion refers to device telescopic rod schematic diagram.The each section of the telescopic rod (2) is by a spring button (5)
It is formed with several card slots (2), spring button (5) is pressed and is stuck on card slot, to realize self-locking function.
In conclusion white silk qin expansion of the invention refers to device, can be made of plastics or metal one it is small and exquisite, foldable, can be with
The exquisite expansion that body carries refers to tool, allows people when the free time, and consciously or not consciously expansion refers to opponent's fingering row
Away from practice, greatly shorten musical instrument beginner correct hand-type process.
Claims (1)
1. a kind of white silk qin expansion of achievable multiple degrees of freedom displacement refers to device, including fingerstall, it is placed in the telescopic rod of the fingerstall side,
It is characterized by: the fingerstall (1) at least two, the telescopic rod (2) is that fingerstall (1) provides displacement supporting role, described to stretch
Spring button (5) hingedly, by stretching telescopic rod (2), is stuck in some card slot (4) by contracting bar (2) beginning and end and fingerstall (1)
