Structure conducive to reduction of fastening element height

Abstract

A structure conducive to reduction of fastening element height, including a fastener and a body portion. The fastener has a head portion, fastening portion, rod portion, resilient component and resilient component placement portion. The body portion and fastener are movably fitted together. Therefore, the body portion is fitted to the first object, such that the fastening portion can be fastened to the second object and removed from the second object, thereby allowing at least two objects to be coupled together and separated repeatedly and rapidly.

What is claimed is: 
     
         1 . A structure conducive to reduction of fastening element height, comprising:
 a fastener having a head portion, a fastening portion, a rod portion, a resilient component and a resilient component placement portion; and   a body portion movably fitted to the fastener.   
     
     
         2 . The structure conducive to reduction of fastening element height according to  claim 1 , wherein the resilient component is placed within the resilient component placement portion. 
     
     
         3 . The structure conducive to reduction of fastening element height according to  claim 1 , wherein the resilient component placement portion is a dent recess, dent hole, dent portion, storage space defined by the fastening portion and the body portion, or storage space defined by the rod portion and the body portion. 
     
     
         4 . The structure conducive to reduction of fastening element height according to  claim 1 , wherein the resilient component placement portion is disposed within the fastening portion. 
     
     
         5 . The structure conducive to reduction of fastening element height according to  claim 1 , wherein, when the resilient component retracts, the resilient component placement portion nullifies retraction height of the resilient component to reduce corresponding height of the body portion. 
     
     
         6 . The structure conducive to reduction of fastening element height according to  claim 1 , wherein the rod portion is partially placed within the resilient component placement portion. 
     
     
         7 . The structure conducive to reduction of fastening element height according to  claim 1 , wherein the rod portion is partially placed within a dent recess, dent hole or dent portion of the resilient component placement portion. 
     
     
         8 . The structure conducive to reduction of fastening element height according to  claim 1 , wherein the head portion is a vertically movable pull member, rotatable operable member, or laterally movable sliding member. 
     
     
         9 . The structure conducive to reduction of fastening element height according to  claim 1 , wherein motion of the head portion causes the fastening portion to move toward the body portion, such that the resilient component is stored in the resilient component placement portion. 
     
     
         10 . The structure conducive to reduction of fastening element height according to  claim 1 , wherein the resilient component has an end abutting against the body portion and another end abutting against the resilient component placement portion. 
     
     
         11 . The structure conducive to reduction of fastening element height according to  claim 1 , wherein the body portion has a fitting portion adapted to be fitted to a first object. 
     
     
         12 . The structure conducive to reduction of fastening element height according to  claim 1 , wherein the head portion, the resilient component placement portion or the rod portion functions as a fastening portion adapted to be fastened to a second object. 
     
     
         13 . The structure conducive to reduction of fastening element height according to  claim 1 , wherein the resilient component placement portion is a blocking portion, such that the blocking portion and the body portion define a storage space. 
     
     
         14 . The structure conducive to reduction of fastening element height according to  claim 1 , wherein an end portion of the resilient component placement portion and the body portion are fitted to each other to define placement space height of the resilient component placement portion. 
     
     
         15 . The structure conducive to reduction of fastening element height according to  claim 1 , wherein the body portion has a blocking portion for blocking the resilient component or the resilient component placement portion, the blocking portion being a flat surface portion, stepped portion, dent portion, raised portion, oblique surface portion, arcuate surface portion or curved surface portion.
