Quick release connecting device

Abstract

A quick release connecting device includes an actuating retainer having an internal receiving space, at least one first push section and a retaining section for detachably engaging with a first object; a fixing member including a body portion movably associated with the receiving space and a pivot portion formed on the body portion for detachably connecting with a second object; pin connection means connecting the body portion to the receiving space for the actuating retainer and the fixing member to move relative to each other within a limited range; an elastic element having two ends pressed against an inner wall surface of the receiving space and the body portion to control the limited movement of the actuating retainer and the fixing member and return them to their original positions. With the quick release connecting device, two mating objects can be conveniently repeatedly connected to and separated from each other.

         6 . The quick release connecting device as claimed in  claim 3 , wherein the body portion of the fixing member includes a long slide hole communicable with the receiving space; and the pin connection means being slidable in the long slide hole to thereby bring the actuating retainer and the fixing member to slide relative to each other within a limited range. 
     
     
         7 . The quick release connecting device as claimed in  claim 1 , wherein the actuating retainer and the fixing member connected to each other via the pin connection means are rotatable relative to each other within a limited angle. 
     
     
         8 . The quick release connecting device as claimed in  claim 7 , wherein the actuating retainer includes a pin connection slot communicating with the receiving space, and the pin connection means being located in the pin connection slot. 
     
     
         9 . The quick release connecting device as claimed in  claim 8 , wherein the pin connection slot is a locating hole formed on one or two lateral walls of the receiving space; and the pin connection means being rotatable in the locating hole to thereby bring the actuating retainer and the fixing member to rotate relative to each other within a limited angle. 
     
     
         10 . The quick release connecting device as claimed in  claim 1 , wherein the pin connection means includes a cylindrical pin integrally formed with or additionally assembled to the body portion of the fixing member. 
     
     
         11 . The quick release connecting device as claimed in  claim 10 , wherein the pin connection means further includes a pin holding hole formed on the body portion of the fixing member; and the cylindrical pin being inserted in, riveted to, expansion-fitted in, glued to or screwed into the pin holding hole. 
     
     
         12 . The quick release connecting device as claimed in  claim 1 , wherein the pin connection means includes a cylindrical pin integrally formed with or additionally assembled to the actuating retainer. 
     
     
         13 . The quick release connecting device as claimed in  claim 12 , wherein the pin connection means further includes a pin holding hole formed on the actuating retainer; and the cylindrical pin being inserted in, riveted to, expansion-fitted in, glued to or screwed into the pin holding hole. 
     
     
         14 . The quick release connecting device as claimed in  claim 6 , wherein the pin connection means includes a cylindrical pin integrally formed with or additionally assembled to the actuating retainer; and the cylindrical pin being transversely extended through the receiving space. 
     
     
         15 . The quick release connecting device as claimed in  claim 14 , wherein the pin connection means further includes at least one pin holding hole formed on the actuating retainer to communicate with the receiving space; and the cylindrical pin being inserted in, riveted to, expansion-fitted in, glued to or screwed into the pin holding hole. 
     
     
         16 . The quick release connecting device as claimed in  claim 1 , wherein the retaining section on the actuating retainer is a hook directed leftward or rightward relative to the actuating retainer. 
     
     
         17 . The quick release connecting device as claimed in  claim 16 , wherein the hook includes a beveled guide surface and a hooking surface connected to a lower edge of the beveled guide surface.
