Twisting roller with a locking and cutting mechanism for wire ends

Abstract

The present invention provides an improved twisting roller with a wire ends locking and cutting mechanism. The twisting roller includes a spool, a baffle plate at both ends, and a housing externally on the twisting roller. The locking groove and cutting groove are assembled onto the baffle plate of the twisting roller or hanging piece of the housing. A cutter is assembled into the cutting groove. The wires can be pulled through the locking groove and cutting groove for direct cutting. After the wires are cut, the wire ends are locked securely into the locking groove, and a portion is exposed for convenient operation and fixation with improved applicability.

1 . A twisting roller, comprising:
 a spool having wires would thereon;   an expanded baffle plate at both ends of said spool;   a cutter and a shield, assembled onto the baffle plate said cutter being assembled between the baffle plate and shield; and   a locking groove and cutting groove, assembled separately at both ends of said shield, said cutter having a blade exposed to said cutting groove.   
   
   
       2 . The roller defined in  claim 1 , wherein the baffle plate is provided with a trough for assembly of said cutter and said shield. 
   
   
       3 . The roller defined in  claim 1 , wherein the baffle plate is provided with a button, and an assembly hole, said assembly hole being placed oppositely said cutter and said shield, said cutter and said shield being assembled and positioned onto the baffle plate. 
   
   
       4 . A twisting roller, comprising:
 a spool, having wires would thereon;   an expanded baffle plate at both ends of said spool;   a housing, being assembled externally and having a hanging piece located on top of said housing; and   a locking groove and cutting groove, assembled separately at both ends of said hanging piece, said cutter having a blade exposed to the cutting groove.   
   
   
       5 . The roller defined in  claim 4 , wherein said housing is comprised of two semi-circular housings, said housing having an assembly surface with a button and locking hole arranged thereon. 
   
   
       6 . The roller defined in  claim 4 , wherein said housing is of a single Π-shaped structure, said housing having a flexible clipping arm is extended towards a bottom of both ends of said housing, the clipping arm having an axle block is protruded at two ends thereof opposite to a center. 
   
   
       7 . The roller defined in  claim 4 , further comprising:
 a recession placed laterally onto the cutting groove; and   a positioning pin placed into said recession, enabling assembly and positioning with said cutter.   
   
   
       8 . The roller defined in  claim 4 , wherein both ends of said housing have a convex portion, preventing wires from being trapped by said housing.
