         3 . The press release buckle as claimed in  claim 1 , wherein said base member comprises a coupling structure disposed around said accommodation chamber; said press member comprises a coupling structure disposed around the periphery thereof and coupled to the coupling structure of said base member to secured said press member to said base member and to allow vertical sliding movement of said press member relative to said base member between the top and bottom sides of said accommodation chamber in opening/closing said retaining gap. 
     
     
         4 . The press release buckle as claimed in  claim 1 , wherein the coupling structure of said press member comprises a plurality of coupling hooks; the coupling structure of said base member comprises a plurality of vertical coupling grooves spaced around an inside wall of said base member within said accommodation chamber for receiving the coupling hooks of the coupling structure of said press member and guiding movement of said press member up and down between the top and bottom sides of said accommodation chamber and a plurality of beveled guide faces located on the inside wall of said base member above said vertical coupling grooves and adapted for guiding the coupling hooks of the coupling structure of said press member. 
     
     
         5 . The press release buckle as claimed in  claim 4 , wherein the coupling structure of said base member comprises a plurality of springy hooks spaced around said accommodation chamber; the coupling structure of said press member comprises a plurality of above said vertical coupling grooves and adapted for guiding the coupling hooks of the coupling structure of said press member. 
     
     
         6 . The press release buckle as claimed in  claim 1 , wherein said base member further comprises two pivot pins respectively horizontally extended from the inside wall thereof at two opposite lateral sides in said retaining gap between said accommodation chamber and said front opening; said coupling shaft of said connection member comprises two pivot holes respectively and axially located on two distal ends thereof for receiving said pivot pins, and two end notches respectively and radially located on the two distal ends in communication with said pivot holes and facing said mounting block for guiding the two pivot pins of said base member into said pivot holes. 
     
     
         7 . The press release buckle as claimed in  claim 1 , wherein said press member comprises a sloping surface portion located on a top side thereof for pressing by said coupling shaft to lower said press member in said accommodation chamber. 
     
     
         8 . The press release buckle as claimed in  claim 1 , wherein said base member further comprises a narrow protruding block raised from the bottom wall thereof in a bottom side in said retaining gap. 
     
     
         9 . The press release buckle as claimed in  claim 1 , wherein said base member further comprises two horizontal stop flanges bilaterally suspending above said retaining gap. 
     
     
         10 . The press release buckle as claimed in  claim 1 , further comprising a mounting structure adapted for pivotally connecting said base member to an external object, said base member further comprising a bottom shank perpendicularly downwardly extended from a flat bottom surface of the bottom wall thereof and a guide block protruded from said flat bottom surface adjacent to said bottom shank; said coupling structure comprising a first mounting plate attached to one side of said external object, said first mounting plate comprising a center through hole for the passing of said bottom shank of said base member and an arched sliding groove located on a top wall thereof and extending around the center through hole and coupled to said guide block of said base member to guide rotation of said base member relative to said mounting structure within a predetermined angle, and a first fastening member inserted through a through hole on said external object and the center through hole of said mounting structure and driven into the bottom shank of said base member to pivotally connect said base member to said mounting structure and said external object. 
     
     
         11 . The press release buckle as claimed in  claim 10 , wherein said first mounting plate of said mounting structure further comprises two bottom mounting posts perpendicularly downwardly extended from a bottom wall thereof at two opposite sides relative to the center through hole of said first mounting plate and respectively inserted into one respective through hole on said external object; said mounting structure further comprises a second mounting plate attached to an opposite side of said external object opposite to said first mounting plate, said second mounting plate comprising a center through hole for the passing of said first fastening member and two mounting holes disposed at two opposite sides relative to the center through hole of said second mounting plate for receiving said bottom mounting posts of said first mounting plate, and two second fastening members respectively fastened to the mounting holes of said second mounting plate and said bottom mounting posts of said first mounting plate to affix said first mounting plate, said external object and said second mounting plate together.
