Apparatus for ligating wires

Abstract

A wire-ligating apparatus for twisting a wire to make a tie, comprises a main body; a rotational shaft rotatably coupled to the main body; a hooking part provided in a leading end of the rotational shaft, holding a wire; and a rotating means provided in the main body, rotating the rotational shaft so as to allow the wire held by the hooking part to be twisted. With this configuration, the present invention provides a wire-ligating apparatus making it easy to ligate the wires and unbind them, and at the same time, reducing the time consumed in ligating and unbinding the wires.

What is claimed is:  
     
         1 . A wire-ligating apparatus for twisting a wire to make a tie, comprising: 
 a main body;    a rotational shaft rotatably coupled to the main body;    a hooking part provided in a leading end of the rotational shaft, holding a wire; and    a rotating means provided in the main body, rotating the rotational shaft so as to allow the wire held by the hooking part to be twisted.    
     
     
         2 . The apparatus according to  claim 1 , wherein the rotating means includes a first driven bevel gear provided on one end of the rotational shaft, a driving bevel gear engaged with the first driven bevel gear, rotating the first driven bevel gear, and a driving part driving the driving bevel gear.  
     
     
         3 . The apparatus according to  claim 2 , wherein the driving part includes a press button exposed outside the main body, and a transmitting part provided between the press button and the driving bevel gear, transmitting a linear motion of the press button into a rotation motion of the driving bevel gear.  
     
     
         4 . The apparatus according to  claim 3 , further comprising a button spring coupled to the press button, elastically moving oppositely to the pressed direction of the press button.  
     
     
         5 . The apparatus according to  claim 2 , further comprising a variable rotating means changing the rotation direction of the rotational shaft.  
     
     
         6 . The apparatus according to  claim 5 , wherein the variable rotating means includes a second driven bevel gear disposed opposite to the first driven bevel gear, being engaged with the driving bevel gear, and an operating lever having a first end coupled to the rotational shaft and a second end exposed outside the main body, allowing one of the first and second driven bevel gears to be selectively engaged with the driving bevel gear by changing the position of the rotational shaft along the axial direction.  
     
     
         7 . The apparatus according to  claim 6 , wherein a means for receiving and supporting the rotational shaft is provided on an inner back side of the main body.  
     
     
         8 . The apparatus according to  claim 1 , further comprising a shaft housing enclosing one portion of the rotational shaft, disposed outside the main body, and a housing spring disposed between the shaft housing and the main body, elastically moving so as to allow the shaft housing to be separated relative to the main body.  
     
     
         9 . The apparatus according to  claim 1 , wherein the hooking part is provided with a pair of hooking portions for holding the wire.  
     
     
         10 . The apparatus according to  claim 9 , wherein on inner faces of the hooking portions are formed threads capable of being engaged with each other.  
     
     
         11 . The apparatus according to  claim 9 , further comprising a holding spring disposed between the pair of hooking portions, elastically separating the hooking portions from each other.
