Telescopic regulation structure

Abstract

The invention relates to a telescopic regulation structure, which mainly consists of an outer body, an inner body, an elastic element, a sleeve body and a fixing and placing device, wherein a stop ring is formed inside the outer body, a groove passage is arranged on the outer body, the inner body is placed inside the outer body, the elastic element and the sleeve body are sheathed outside the inner body, the elastic element is clamped between the stop ring and the sleeve body, and the moving or telescopic position of the inner body relative to the outer body can be determined by regulating the fixing and placing device. The telescopic regulation structure has the advantages that a simple structure is provided, the inner space and the volume can be freely regulated to become larger or smaller, and the operation is very convenient when the telescopic regulation structure is applied to tone tuning of flute musical instruments.

Description

technical field [0001] The telescopic adjustment structure of the present invention relates to a technology for adjusting the internal space volume of an article in a telescopic manner, especially after adjustment, a fixing and placing device can be used to achieve the purpose of fixing. Background technique [0002] Due to the advancement of science and technology and the rapid development of economy, industry and commerce, in this era of rapid industrial changes, although many items have been developed by predecessors, the functions of many structures are still not perfect, and there is still room and necessity for improvement and progress. [0003] In the known article structure, an inner daughter body is accommodated in an outer mother body, and the inner daughter body cooperates with a spring to move back and forth relative to the outer mother body. Its force control is still not ideal; for example, the structure shown in Taiwan Patent Publication No. 405561 "Improvemen...

[0003] In the known article structure, an inner daughter body is accommodated in an outer mother body, and the inner daughter body cooperates with a spring to move back and forth relative to the outer mother body. Its control of force is still not ideal; for example, the structure shown in Taiwan Patent Publication No. 405561 "Improvement of Bicycle Shock Absorber Combined with Pivot Structure" is an example, and it really needs to be improved
