         4 . The female lock of the string-locking device as  claim 1 , wherein the bottom board has binding surface connecting to the cloth element, the binding surface of the bottom board is installed with multiple protruding blocks; 
     
     
         5 . The female lock of the string-locking device as  claim 4 , wherein the protruding blocks installed on the binding surface of the bottom board are respectively a cone protruding block; 
     
     
         6 . The female lock of the string locking device as  claim 4 , wherein the protruding blocks installed on the binding surface of the bottom board are circularly installed on the peripheral of the connecting hole; 
     
     
         7 . The female lock of the string locking device as  claim 1 , wherein the main body is installed with an assembling grove, the front opening hole penetrates the two opposing walls of the assembling grove; 
     
     
         8 . The female lock of the string locking device as  claim 2 , wherein the main body is installed with an assembling grove, the front opening hole penetrates the two opposing walls of the assembling grove; 
     
     
         9 . The female lock of the string locking device as  claim 3 , wherein the main body is installed with an assembling grove, the front opening hole penetrates the two opposing walls of the assembling grove; 
     
     
         10 . The female lock of the string locking device as  claim 4 , wherein the main body is installed with an assembling grove, the front opening hole penetrates the two opposing walls of the assembling grove; 
     
     
         11 . The female lock of the string locking device as  claim 5 , wherein the main body is installed with an assembling grove, the front opening hole penetrates the two opposing walls of the assembling grove; 
     
     
         12 . The female lock of the string locking device as  claim 6 , wherein the main body is installed with an assembling grove, the front opening hole penetrates the two opposing walls of the assembling grove; 
     
     
         13 . A string locking device, containing female lock, male lock, and an elastic structure;
 the female lock contains a string restraining base and a bottom board, the string restraining includes a main body and a hollow bolt; the main body has a binding surface, and installed with an assembling grove; the binding surface is installed with a front opening hole penetrating the main body and connecting to the front opening hole; the hollow bolt penetrates the connecting hole of the bottom board and is bolted to the bottom board so that the protruding blocks on the binding surface of the main body press against the surface of cloth between the hollow bolt and bottom board;   the elastic structure is installed on the bottom of the assembling grove;   the male locking device has a lock body, the lock body is installed with a male lock opening hole, the male lock is assembled to the assembling grove so that the lock body presses against the elastic structure in order to accept a spring force, wherein the hole size and direction of the male lock opening hole matches with the hole size and direction of the front opening hole; the male lock also has a limiting section so that the bottom of the lock body is always sit in the assembling grove;   
     
     
         14 . According to the string-locking device stated in  claim 13 , wherein the limiting section is a clicking hook installed in the lock body so that when the spring force is larger than external force can press against the upper side edge of the front opening hole; 
     
     
         15 . The string-locking device stated in  claim 13 , wherein the elastic structure is a spring.
