Specific embodiment

With reference to the accompanying drawing, specific embodiment of the present utility model is described in detail.

Join shown in Fig. 1-2, Fig. 1 is the binding clip expanded configuration schematic diagram of rotatable tool pincers provided by the utility model；Fig. 2 It is the binding clip closing structure schematic diagram of rotatable tool pincers provided by the utility model；

The utility model provides a kind of rotatable tool pincers, including handle 3, binding clip 1, casing group 2, shaft coupling 4, casing Group 2 includes mutually nested internally positioned inner tube 6 and external outer tube 5, and casing group 2 connects binding clip 1 and handle 3, Thus handle 3 control binding clip 1 movement；Shaft coupling 4 is connect and rotatable relative to handle 3 with handle 3；Shaft coupling 4 is arranged On outer tube 5, outer tube 5 is rotated with shaft coupling 4 and is rotated around the central axis of the outer tube 5, is arranged inside the outer tube 5 interior Pipe 6 moves one end that binding clip 1 is pivotably coupled to the separate handle 3 of outer tube 5 along 5 central axis of outer tube；Binding clip 1 with it is described interior The connection of pipe 6 is to the movement with inner tube 6 in outer tube 5；Handle 3 drives said inner tube 6 to be axially moved, to realize that binding clip 1 is opened Open and close are closed.

Wherein, handle 3 provided by the utility model includes fixed handle 9, flexible handle 10；The flexible handle 10 is opposite It is moved in fixed handle 9, the flexible handle 10 drives said inner tube 6 to be axially moved, to realize the open and close of binding clip 1 It closes.And the handle 3 in the utility model includes fixed handle 9, flexible handle 10, in this way by exerting a force on flexible handle 10, The folding of binding clip 1 can be driven, it is relatively laborsaving.In addition, outer tube 5 is process by stainless steel tube, outer tube 5 is hollow structure, The wall thickness of outer tube 5 is 0.3-0.5mm.The outer diameter of outer tube 5 is 5-8mm.
